Waste oil burner

For many homeowners, keeping their house warm and comfortable throughout the winter is a top concern. Conventional heating techniques, however, can be expensive and harmful to the environment. Waste oil burners can help with that. By recycling spent oil that would otherwise be thrown away, these cutting-edge gadgets provide an economical and environmentally responsible way to heat your house.

In essence, a waste oil burner is a boiler or furnace made especially to burn used cooking oil, motor oil, or other waste oils as fuel. Waste oil burners offer a sustainable method of utilizing these oils’ energy for heating as opposed to letting them go to waste or disposing of them incorrectly. This helps homeowners save money on heating expenses while also lessening the environmental impact of oil disposal.

The adaptability of waste oil burners is one of their main benefits. Residential residences, garages, workshops, and even small businesses can all make use of them. Waste oil burners are an affordable, dependable, and effective way to heat your workspace or living area without going over budget.

In addition, waste oil burners are more efficient than conventional heating systems. With these burners, you can cut down on the amount of fuel required to keep your home comfortable by a significant amount by recovering energy from used oil that would otherwise be wasted. This helps create a more sustainable and greener world in addition to saving homeowners money.

Making the nozzle of the waste oil burner

The most crucial component of a waste oil burner that you assemble yourself is the nozzle. The system’s safety and fuel efficiency are determined by how precisely it was manufactured. The burner will be more powerful the larger the nozzle orifice.

Furthermore, the air intake channel must be even and smooth in order for the torch’s shape to be ideal. Using pre-made jets with a hole of the necessary diameter, such as those from a gas stove or carburetor, is the best option.

However, using a drilling machine to drill a hole is also an option. Because it can be challenging to ensure that the hole is aligned, using a hand drill is not advised.

A hemispherical nut or a furniture handle with an appropriate diameter can be used to create the hemisphere. It is recommended to mount the nozzle flush with the hemisphere’s surface. In the worst situation, a metal strip bent like a rule with a nozzle welded to it is all that is needed.

It is possible to estimate the power of the resulting burner in advance with a known error. A burner that has a single 0.3 mm hole in it can generate about 16 kW of heat. If you require more power, it is preferable to create multiple holes spaced at least 8 mm apart rather than enlarging the existing hole. Experiments have demonstrated that when the aperture size exceeds 0.3 mm, the airflow becomes turbulent, resulting in a worse capture of waste vapors and a decrease in the device’s thermal efficiency.

Making the burner cover

A cover element allows access to the waste oil compartment during ignition. This component should weigh in a meaningful enough way. It is fixed to pre-welded canopies that are meant to be fixed to the structure’s neck. There is a chance that the device will spontaneously open while the burner is operating if the element is made with a less impressive weight. By observing the flame that forms when the oil-oxygen mixture burns in the structure’s body—which should be even and violet in color—you can determine whether the burner is operating correctly.

Advantages and disadvantages

The ability to use heavy liquid fuels is the primary benefit of the Babington supercharged burner. Waste oil, diesel, fuel oil, vegetable oil, biodiesel, and kerosene can all be used to power a homemade boiler. The burner operates well and heats the room efficiently even when there is paraffin, water, and other impurities in the fuel. All you need to keep in mind is that the boiler will need to be reconfigured, which will involve adjusting the amount of air that enters the combustion chamber and changing the fuel type.

The oil burner’s design is straightforward, allowing for complete independence in work performance. Correctly dosing the air and fuel mixture can be challenging, though. There is a need to use two finely adjustable pumps simultaneously. Additionally, every connection must be made completely tight to prevent air infiltration and, as a result, a decline in the equipment’s efficiency.

The tiny nozzle of the burner may clog during operation, which could impair the quality of fuel combustion by causing issues with the air mixture supply. If the heating boiler is utilized frequently, it is advised to carry out a thorough cleaning of the entire system every few months.

Taking the proper precautions against fire is also essential.

The heating boiler and burner must be placed far from any combustible materials, and fire-safe materials must be used to finish the floor and adjacent walls. Having a powder fire extinguisher that has been refilled on hand will help you put out an oil burner quickly in the event that one does break out.

General information

The Babington boiler appeared a long time ago and it is quite easy to guess who was its creator. Currently, the scope of application of such mini heating equipment is limited to heating of small rooms. Interestingly, the burner can be assembled from improvised materials and does not require any investment. In addition, there is no need to organize a chimney, as the combustion process does not produce smoke. Nevertheless, it is still necessary to take care of good ventilation in the room. By the way, the patent for the Babington burner was removed relatively recently, so in recent years the drawings of the unit have become available to everyone. But before proceeding to the assembly process, we would like to understand in detail how the device works. And first, a little history.

Fuel characteristics

Not only is waste fuel unclean, but it also sticks a lot. Ensuring that engine oil sticks to a thin layer of rubbing surfaces when operating in harsh conditions is one of the functions of additives in engine oil. Because too viscous fuel will not mix well with air, will not pass through the nozzle of the nozzle, or will not cover the atomizing head with an even layer, waste oil burners operate almost exclusively on fuel heating, which increases the fuel’s fluidity (see below). below).

Additionally, it is difficult to ignite waste fuel—to get it to burn as strongly as engine oil in a hot engine? Actually, the only tools that work well for quickly and consistently igniting waste oil are an electric spark and a gas torch. Nevertheless, there is one exception—see below.

Thirdly, the spent fuel contains water and/or antifreeze from the engine cooling system in addition to solid particles. Fuel filtration is a fairly involved procedure. Only if the fuel waste is continuously available, such as in the form of a fuel filter, does it make sense to organize it. A waste oil burner that is occasionally used in a fairly large and busy machine shop needs to be insensitive to both the water content of the fuel and solid contaminants.

Electricity for burner

This leads to the unfavorable conclusion that waste oil burners are not energy-independent. While it is possible to burn waste oil without heating or supercharging, these devices (see "The Waste Oil Combustion System") are not appropriate for waste oil combustion. below) are not burners per se; rather, they are components of heat-generating devices that were developed in tandem with them and only provide acceptable technical and environmental performance. It is therefore preferable to use a boiler or a waste oil burner if your power supply is unstable and waste oil is sufficient.

Advantages and disadvantages of the oil burner

There are several benefits to the oil burner designed by Babbington:

• Simple design, no moving parts.
• Affordability to make at home.
• Availability of well-calculated and accurate drawings on the Web.
• Exceptional cheapness of fuel. Enterprises that own a large fleet of automobile and tractor equipment can significantly save on heating and at the same time on the utilization of waste oil.
• High energy efficiency. Other waste oil burners use considerably more fuel per kilowatt of heat energy.
• Small dimensions allow the burner to be integrated into existing heating systems without significant modifications to them.
• High degree of fire safety.

The burner has a number of drawbacks in addition to these benefits.

• Sensitivity of the fuel path to contamination. Waste oil will have to be filtered.
• The need for electrical power to operate the fuel pump and air compressor.
• Unpleasant odor during operation. It is better not to use the burner in the premises of permanent presence of people or farm animals, or it will be necessary to ensure reliable removal of combustion products.

At-home waste oil burner

Overall, the benefits greatly exceed the drawbacks, and the Babbington burner is becoming more and more well-liked.

Burner operation

The burner’s simplified scheme is provided in the article, making it possible to comprehend the basic idea behind how it works. After atomization, the mixture is lit on fire and the flame is put to use. This burner can be installed in a boiler that runs on any kind of fuel. Generally speaking, nobody stops you from building the boiler yourself.

Keep in mind that there is essentially no vaporization while the system is operating because compressed air plays the majority of the role and all processes occur at low temperatures.

One way to improve combustion efficiency is to build a heating system and use only low-power TENs in it. In this instance, there will be a rise in efficiency, an improvement in heat transfer, and a beautiful, even flame.

How the burner appeared

Back in 1969, the inventor Robert Babington was granted a patent for this burner. It"s true that his term has long since expired. In 1979, Babington proposed a new burner design. It was fundamentally different in that it had a double air atomizer. This invention was very similar to the burner "Eirtonic", which was also made according to the technology of this inventor. It was used for military purposes on Naturally, the burner was powered by diesel fuel and was irreplaceable. The final design was proposed by John Archibald. Many people call this man the inventor of the Babington burner. But it"s impossible to give a definite answer. And I don"t think that"s important to us. The most important thing is to be able to create such a unit with your own hands and achieve its effective operation. Fortunately, this is not as difficult to do as it may seem at first glance.

What is required for manufacturing

A Babington burner diagram. (Toggle to make larger)

The burner is not at all difficult to assemble, but for smooth operation, a few parts need to fit together just right.

The burner is composed of the subsequent components:

1. Babington nozzle, as which a door handle may be used. It is usually placed in the burner.
2. A 20 lb (9 liter) propane cylinder that will act as a source of compressed air.
3. The pump for the liquid fuel is usually a gear oil pump. Connected via copper tubing.
4. A trimmed propane cylinder with a capacity of 100 pounds (45.36 liters) can fit as a burner guide tube. Mounted at the required height. You can also make do with a blowtorch.
5. A sump to collect impurities that have not been burned. A cut-off unnecessary cylinder will do.
6. A splash trap, because without it there will be splashes everywhere. For this purpose, a piece of beam is used.

This is crucial: since this kind of fuel can be hazardous, it is advised to prepare a fire extinguisher before creating the burner.

The principle of functioning of the burner

The waste, in our case fuel, is fed through a curved tube. As a result, due to the effects of surface tension, a thin film is formed which is pierced with air from tiny holes, usually no more than 0.010 mm in diameter. As a result, the fuel is atomized and enriched with oxygen. For this reason, no additional systems are required to organize the air supply, as the process is completely complete. This design is best suited for working with waste oil. This is due to the fact that regardless of the quality of the fuel composition and the presence of foreign elements in it, the burner will function. Of course, the heating efficiency in this case will be somewhat altered. Nevertheless, the Babington waste oil burner should be equipped with a sump with oil, which will be fed to the working body of the device with the help of it. Although this is a disadvantage, but it can not be called a significant disadvantage in any way.

Making a waste oil burner

The waste oil burner with its own hands, the working model of which is presented in the article, will work as effectively as the oxygen flow turns out to be intensive. At the heart of the system for correcting this parameter is a cup made of metal. It has a semicircular bottom, among other things, it has a hole that has a given diameter. This fairly simple part can also be made on a lathe. Make the bottom in the form of a hemisphere can be made with the use of cutters, and the work should be done by a professional turner. Correct the air flow with a curtain, which has a round shape. Its attachment should be made on the L-shaped axis, using for this purpose a screw M4, only in this way it will be possible to obtain a strong interface, which will have a burner made with their own hands, waste oil in it can become dangerous. But to avoid problems that can lead to fire, you can, if you follow the rules of fire safety.

An adapter needs to be used to guarantee a dependable connection between the hose and the outlet pipe. The latter needs to have a slit running the whole length of it. Among other things, the adapter will guarantee that the air gate valve operates normally.

Recommendations on manufacturing

Owing to its simplicity and widespread use, waste oil boiler burners are crafted by artisans in various forms. Here, we will outline the most basic design that can be replicated at home. First things first, you need to gather the required supplies. This is their list:

• Steel tee with internal threads with a diameter of 50 mm – for the body.
• A bend with external thread with a diameter of 50 mm – for the nozzle. Its length is taken at will, but not less than 100 mm – for the nozzle.
• Elbow made of metal DU10 with external threads – for connecting the fuel line.
• Copper tube DU10 of the required length, but not less than 1 m – for the fuel line.
• Metal ball or hemisphere, freely entering the tee – for the working part.
• Steel tube not less than DN10 – for air line connection.

Making a hole in the center of the sphere is the only precise action required to create a waste oil burner by hand. The hole’s diameter should be between 0.1 and 0.4 mm, ideally 0.25 mm. It can be made in two ways: either install a pre-made jaculator at 0.25 mm or drill with a tool of the proper diameter.

Crucial! The sphere will be installed in a housing (tee), so the hole must be made precisely in the center, with its axis parallel to the walls. Minimal deviation is permitted; otherwise, the torch may veer to one side, affecting the burner’s stability and efficiency.

Accurately drilling a hole this small is difficult since thin drills are brittle. Here are some guidelines on how to do this correctly:

Inserting the necessary diameter jets into the autonomous burner’s spherical portion is an additional method of creating a calibrated hole in it. In order to accomplish this, a reamer is used to process a hole that has been drilled with a diameter that is marginally smaller than the jets’ outer diameter. As shown in the video, the joker is polished and compressed inside.

Note: If large capacity burners are required, the jet diameter can be increased to 0.4-0.5 mm or two small holes drilled at least 7 mm apart can be drilled.

After this process is finished, we assemble the burner using the drawing as a guide:

It is required to drill a hole large enough to ignite the unit on the side of the nozzle. It is sufficient to have a fuel heating spiral with two to three turns in diameter. The completed item can be installed into any boiler, even a homemade one, by fixing it on a mounting plate. Once the work is completed, arrange the oil and air supply before connecting the fuel and air lines. The most basic way to supply fuel is by gravity; to do this, a waste oil container is hung from the wall above the burner, and a pipe is run from it.

Using a pump to transfer the oil allows you to use control units, monitoring sensors, and an automatic burner that is safer to use. The video provides comprehensive instructions for choosing components and putting the device together:

The burner’s fuel consumption shouldn’t go above one liter per hour if everything is done correctly and the air hole diameter is 0.25 mm. To ensure an even burning torch, there should be no black soot during combustion. The sphere can be moved back and forth or the air pressure can be changed to make adjustments. As long as the working pressure stays below 4 bar, any compressor—even one from a refrigerator—can handle its discharge.

Safety measures

• Oil burner and other HSPs can be dangerous if installed and operated incorrectly, to avoid fire it is necessary to follow a number of measures:
• Floors and walls made of combustible materials are covered with metal or asbestos sheets;
• The fuel reserve must be kept at a safe distance;
• oil leaks must be removed in good time;
• electrical components of the unit must be carefully insulated to avoid sparking in the area of oil atomization;
• the burner must be located out of reach of air currents and draughts.

When operating, a burner with an open nozzle should never be left unsupervised!

Unlike the blowtorch, the Babington burner is designed to run on waste oil; it is a dependable and long-lasting device that doesn’t require complicated maintenance. Sufficient maintenance procedures include blowing out the ducting at idle, periodically cleaning the fuel system, tank, and sump, and ensuring the compressor and oil pump are in good operating order. A long-lasting, cost-effective appliance with a long service life is a serviceable burner.

How the air is regulated

The determination of the airflow force will determine the fire’s intensity.

The system’s fundamental component is adjusting a steel ball or cup with holes of the proper size and a semicircle-shaped bottom.

A lathe is also used for this. Chisels are used to cut the proper hemisphere. It is fastened to the m4 screw’s L-shaped axis.

Remember: an adapter with a slit running the length of it is used to securely attach the hose outlet and guarantee correct operation of the air valve.

A heavy lid provides access to the machining chamber when ignition occurs. It is fixed to the body’s neck using welded canopies. It can open unintentionally when the weight is light. When the assembly is assembled correctly, the air-oil mixture inside the appliance burns, producing a violet flame with a uniform background while it is in use.

Note from the expert: In accordance with safety regulations, it is imperative to safeguard the nozzle-hose junction. A steel screen can be used to accomplish this. In the event that there are any loose joints, this will prevent the waste oil fuel from igniting.

Although making this burner is not too difficult, it is important to follow safety precautions both while working and in the future. It is crucial to understand that selecting a cylinder for the construction of the appliance body requires extra caution. When holes are made, the cylinder must be empty to prevent serious injuries.

See the video where the expert walks you through the process of creating a Babington burner by hand:

What is the difference between a blowtorch and a Babington burner?

It’s common to compare the operation of a supercharged burner to that of a blowtorch. Indeed, there are some similarities between their devices. However, the working principle is entirely different. Gasoline in a closed container is subjected to high air pressure produced by a hand pump in a blowtorch. The fuel is merely propelled upward toward the nozzle by this air; it does not mix with it. The gasoline travels through the pipe casing, where it is heated and vaporized before entering the injector nozzle. As it exits, the fuel burns and combines with the surrounding air to create a strong flame torch.

In a vertical Babington waste oil burner, everything occurs in reverse. Instead of fuel, air is forced through the nozzle, and the tainted oil is only heated to a specific temperature (no more than 70 ºC). In addition, some of the liquid burns and enters the sump rather than burning entirely. It is not possible to make a waste oil burner from a blowtorch because of how difficult it is to vaporize the waste oil and feed it through the nozzle into the combustion zone. This is just as risky as filling up a Babington unit with gasoline; it’s not only ineffective.

Drilling the holes

The opening’s diameter should be as small as feasible to allow the air flow to atomize the fuel as effectively as possible. One millimeter is the priority. Even so, holes as small as 0.020 are allowed. Special thin drills are used to extract them. You will see them sporadically if you view them from the side. Either way, the drilling procedure needs to be done cautiously and slowly. These holes will allow compressed air to pass through.

When it comes to spraying, air is a better option than gas. This is because the resource is so inexpensive. Paying for gas does not exempt you from paying for air. Furthermore, it requires very little, so standard aquarium compressors can be used. The Babington burner, the drawings of which are available in this article, is practically operational in theory. There are still a few minor details.

The main advantages of appliances

The mentioned burner can easily be made by you yourself. It will be possible to take it with you to the garage, to the dacha or on a camping trip, as well as in those places where there is no electricity, main gas or wood stoves. With the help of such a device, you will be able to heat water, cook food or heat a room quite quickly. Such an invention is suitable for those places where you can not make a fire, because the device produces a flame that is almost invisible, but it will be enough for cooking. The alcohol burner has a lot of advantages, among them we can highlight good performance in difficult weather conditions. And this is true even if the outside temperature drops to -40 degrees Celsius. If you make such a device yourself, you can feel how easy it is to use, compact, economical and affordable in terms of fuel purchase. The last factor can be called one of the most important advantages of such burners, as alcohol can be purchased everywhere. Among other things, the cost of such fuel is low, especially if you compare it with kerosene or gas.

Manufacturing of the installation

The gadget appears more like an empty gas cylinder from the outside. Locate an empty gas cylinder with the appropriate volume first.

The pouring funnel is then taken out and labeled for pipe fastening.

Within the indicated circle, pipes are drilled holes. It will be necessary to drill using a spiral-shaped drill bit. To eliminate the bridges that are between the drilled holes, use a chisel and a bolt cutter. One uses a mill or a round file to provide the desired shape.

After being made, the pipes are welded into place. A bolt cutter is used to saw off pipes after they have been measured. The lower portion of the pipe has a hole drilled for the m16 nut to be welded to. It is necessary in order to fix the oil nozzle.

What is a Babbington burner

The Babbington burner’s liquid fuel design is straightforward enough to construct in a home workshop by one person. The primary components and assemblies of the waste oil burner are as follows:

• tank with waste oil;
• fuel line;
• fuel pump; included in the break in the fuel line;
• A hemisphere with a hole of small diameter;
• air nozzle coming out of this hole;
• drip tray.

Diagrammatic schematic of the burner apparatus

At a certain altitude above the hemisphere, the fuel line ends. The exhaust runs down it and evaporates, drawing the vapors into the air stream to form a fuel mixture. The fuel that hasn’t had time to evaporate drips into the tray and returns to the fuel tank via a network of pipes.

Even though the device looks simple, precise manufacturing of the main parts and their proper positioning in relation to one another are necessary for both safe and effective operation. As a result, it is preferable to download the Babington burner ready drawings and adhere to the dimensions listed there.

Boiler automation

The burner can also be fitted with control automatics, which greatly increases the technique’s functionality. The control unit will be in charge of the burner’s intensity, enhancing safety and greatly enhancing fuel economy metrics.

Certain burner design schemes require the installation of water and flame temperature sensors as well as an extra controller. After obtaining the required data from external modules, the control unit shuts off the pump or closes the fuel line valve as needed. Both pre-made automation and homemade automation are options.

Popular are combined units that run on waste oil and other biofuels; if needed, built-in electrical elements can be used to heat the coolant. The ease of living in a private residence can be greatly enhanced by using a handmade oil burner, which is widely applicable in resolving heating issues in various rooms.

Working principle

The oil-air mixture is supplied through a pressurized nozzle in the majority of well-known oil burners. On the other hand, the Babington system uses a low-pressure pump to supply the oil, which then freely flows over or near a sphere-shaped surface. The fuel condenses into a thin layer and evaporates, being removed by the pressurized air stream that enters a tiny (up to 0.3 millimeter) hole in the sphere’s center. Fuel mixture plumes are created when air and oil vapor combine. When this torch is lit, the liquid heat exchanger in the boiler or the walls of the furnace both receive the necessary heat.

A portion of the oil runs off below the hole and into the fuel collection pan because it does not have time to evaporate and burn. Additionally, the spent oil is recycled as it enters the fuel tank from the sump.

Waste oil is heated to improve its fluidity and vaporizability. The device’s overall efficiency and the quality of the fuel mixture are enhanced by the heated waste oil being atomized into smaller droplets.

Waste oil burner with your own hands

One can construct the burner itself using unconventional tools such as copper tubing, fittings, and angles. The device works on a very basic principle: waste oil and air must be mixed in a specific ratio and heated.

The picture illustrates the general layout of the burner.

Here, air enters through the upper channel and oil enters through the lower tube. There is a side slotted nozzle on the air upper tube. The air channel’s cross-section measures 0.8 mm, while the oil hole measures 2 mm in diameter. In this basic system, the amount of oil used is determined by the air supply; the higher the air flow, the greater the amount of waste oil used.

Additionally, the burner’s approximate scheme is depicted in the picture below.

Here’s an illustration of a do-it-yourself installation:

• a homemade waste water boiler has been welded;
• The burner is mounted on top of the tank, the oil supply is regulated by a tap;
• on the side at the bottom of the boiler there is a heating element, it is necessary only for the initial heating of oil up to the temperature of +60ºC, further the heater is switched off and is not needed anymore. The heating element is located at such a level that it is always in oil and will not burn (3 cm below the bottom level) ;
• during operation there are about 50 grams of oil in the tee, the waste heats up very strongly, so there is no sense in keeping the heating element switched on;
• on the side of the tank for control there is a translucent tube, with its help you can see how much oil is currently in the tank;

• the level is marked on the tank with lines, the maximum level on the top and the minimum level on the bottom;
• automatic oil supply to the tank here is carried out through a crane, which is installed at the bottom of the tank on the side;
• the burner itself is attached through a metal spacer to the tank body, it gets very hot during operation;
• the system is connected to a compressor, in order to start the device, the compressor must be switched on. To start the pressure needs a small, somewhere 0,1-0,2 Atm;
• then it is necessary to open the oil supply and ignite the burner;

• In such a scheme, the working air pressure of 0.5-1 Atm is sufficient, and the oil is consumed very economically.

Such a burner is more than sufficient to heat a small space; the system uses waste and air resources wisely, so a strong compressor does not need to be installed. Large rooms therefore require a more powerful installation, and it is preferable to heat a boiler with a liquid filler via pipe distribution rather than using air.

General view of the finished construction

The flame will be maintained with the aid of a cinder block near the outlet.

There should not be any smoke when the burner is operating properly. There will only be hot, wavy air at the output.

The burner has an oil pump underneath it. Its function is to draw oil from the settled oil tank, which travels twice around the propane cylinder (while it is heated), exits through the door handle, and splatters.

Note: Since controlling the propane supply solely with the cylinder handle is very inconvenient, there is no regulation of the propane supply in this installation; automation can be installed on everything else.

Additionally, the suspension is immediately poured into the sump, eliminating the need for a fuel tank and simplifying the design. Although there are several drawings of these burners, we will now focus on the most basic version.

Benefits of this kind of burner:

• Easy enough to make without anyone"s help.
• cheap way of getting heat.
• An efficient and functional device, it is lightweight, which gives the design mobility.

The experimental part

A reservoir with a 70 milliliter capacity can be used. The nozzles should be made in 16 pieces, with one centimeter separating each one. With a single refill, the approximate burning time is 25 minutes. Experience has shown that the type of fuel used in such devices affects both the duration and intensity of combustion. The medical alcohol vapors provide the best combustion. It burns less intensely when salicylic acid is used in those circumstances. The burner will indicate the shortest burning time if it is powered by food alcohol.

Pros and cons of the Babington burner

This kind of burner device is unique in that its positive and negative sides counterbalance one another. The use of heavy liquid fuels of any quality is the main benefit, as you may have already surmised. A homemade burner with an air supercharger can operate effectively even when the waste oil contains a lot of impurities (unlike other stoves made for the use of similar fuel).

Small malfunctions could happen, but the presence of water or car antifreeze in the waste water (within acceptable bounds) is not a problem. The truth is that liquid hydrocarbons have a lower surface tension than water. As a result, when air is forced into the Babington burner, the waste oil film separates from the working surface more readily. In the event that there is a small amount of water present in the oil, it essentially flows down into the sump rather than into the combustion zone.

Advice: Abusing the burner device’s "omnivorousness" is still not worth it. Prior to use, it is preferable to pass the waste oil through a coarse mesh filter.

The large variety of liquid fuels that can be utilized is another feature that makes the user happy. It is true that the burner’s fuel and air dosages will need to be adjusted when converting from one to the other. These kinds are listed as follows:

• waste oils and fuels of any origin and viscosity – from automobiles, machine tools and other machines and mechanisms;
• diesel and biodiesel;
• fresh, old and burned out vegetable oils;
• fuel oil;
• light-colored heating oil, kerosene.

And now for the drawbacks, which are equally manifold. Handcrafted by them, the Babington oil burner is a comparatively basic apparatus. Additionally, it can be difficult to arrange the drainage and dosed fuel supply. To control the intensity of combustion, you need a fuel path with a dosing system, a pump, and two containers. Simultaneously, it is imperative to guarantee the dependability of connections, lest the oil eventually begin to leak.

The boiler room is seldom clean when the house is heated by liquid fuels, much less when waste oil is burned. It should be acknowledged that the furnace room will inevitably contain dirt and smells. This is particularly noticeable when attempting to troubleshoot or modify the Babington burner to function with a homemade stove or other device. Equipment reconfiguration to convert from waste oil to diesel, fuel oil, or vegetable fuels is also included in this.

Every now and then the burner breaks down because the nozzle—more specifically, the tiny air hole—clogs. The compressor side is most likely the source of the issue. For instance, a worn-out piston group can result in malfunctions by allowing oil from the crankcase to enter the nozzle.

It is important to discuss fire safety precautions separately. It is advised to have a fire extinguisher close by when performing any work associated with installing an oil burner. The latter must always be kept in the boiler room.

Functioning principle of the burner

By using a high-pressure air jet to atomize the fuel, the burner produces results. A tiny hole has been drilled in the spherical surface, through which the fuel flows. A pressurized air tube is located inside the sphere. It bursts through a small aperture, atomizing and blasting off part of the fuel to form a torch in the shape of a cone.

The remaining fuel enters a unique sump beneath the sphere through gravity. After that, it can go back to the main tank.

Though there is a big distinction between the two, some people think the burner’s working principle is similar to a blowtorch’s.

Principle of operation for the waste oil burner

Air moves the fuel in a blowtorch without mixing with it. Additionally, a cone of atomizing aerosol is created in the Babington burner when the air jet goes straight through the fuel stream. This makes sure that tiny droplets have better contact with oxygen in the air, which improves fuel burning efficiency. For this reason, oil could be burned, but gasoline is used in blowtorches.

The torch may become unstable, extinguish itself, or explode when the burner is lit. This is a result of the fuel not having had enough time to properly warm up.

Remodeling industrial burners

It is important to note that building a waste-oil burner from the ground up is far simpler than modifying commercial models. You will still need to make investments, after all. For instance, you will need to spend a lot of money remodeling the diesel fuel burner. As a result, the design becomes extremely complex and the oil needs to be heated. Purchasing an already-made oil burner or creating one yourself is far less expensive.

Some people try to make a burner from a blowtorch. But this is not a very good option, because the principle of its operation is very different from what is necessary. The nozzle is heated and the oil is forced out of the nozzle by pressure. Gasoline is a purified fuel, which is not the case with waste oil. It contains metal impurities, combustion products of diesel or gasoline, as well as other types of contaminants. As a result, the nozzle clogs very quickly. You can, of course, modernize it, but it"s not worth it – it"s too expensive and labor-intensive. Therefore, it is recommended to favor the Babington burner.

Infrared heater

The idea of making an infrared heater by hand might have originated from the use of homemade gas burners. These heaters are intended for use in garages or homes where gas prices are continuously rising. The simplest method of staying warm is to use regular kitchen foil. The wall behind the radiator is where it should be mounted. Heat will not be able to escape through the walls because heat streams will be reflected from the aluminum surface and into the space.

A spiral can be used in a more complex version. You will need to buy an infrared port and an incandescent coil from the store in order to accomplish this. It is very easy to make such a device: all that needs to be done is insert the spiral into a metal block that is connected to the electrical grid. The resulting structure is connected to an infrared port. The basis for this device’s operation is the port’s capacity to transmit the thermal data it receives from the hot spiral throughout the room.

A heater designed with a small tin box and graphite sand is ideal for garages and other small non-residential spaces. Such a device is very small, takes up little room, and does the tasks that are given to it flawlessly. It is necessary to completely wash and dry the container before beginning any work.

It is crucial that it matches your vision of what the ideal future heater should look like, even though it can be any size or diameter.

Fill the box halfway with a mixture of one part graphite to one part fine sand. A circle the right size for the iron container must be cut out of a sheet of tin plate, and the lead wire must be attached to the edges of the circle. This structure needs to be placed on top of a sand and granite mixture, then covered with the leftover mixture. Next, a lid needs to be placed on the container and tightened to create artificial pressure. The vehicle battery is linked to the vessel body’s second wire.

A cover on such a device allows for control over the heating temperature. The temperature of the tin box will be stronger with tighter screws. It will lose heat with less. It’s crucial to keep such heaters from overheating. In these situations, the box will start to glow red or orange. The process of sand sintering happens when the homemade gas burner overheats, which reduces its efficiency. Gut shake the device to make it work again.

Gas infrared heater is more expensive in terms of materials, as it requires the purchase of a small infrared ceramic heater. It is best not to buy a large device, since it will be "fed" from a small propane cylinder, with a volume of 1 liter. In addition, a burner is needed – a nozzle with a special tap. First of all, you need to get rid of all the burner nozzles, leaving only the pipe and the faucet. A hose is put on the pipe, which should be a little more than half a meter long. To this device and connects the cylinder with gas. It is very important that it is in a vertical position when doing so, as the gas movement is upward, not horizontal. Such a heater works for two hours on an ordinary 200-gram cylinder.

Fishermen often use such a device during winter fishing in a tent. A stock of gas cylinders allows you to comfortably spend the night on the ice. In addition, this design is safe, there is no open flame that can cause harm. Ceramic tile is enough for 10 minutes until it is fully heated, after which it begins to actively radiate heat, heating the air around it.
How to make a gas burner with your own hands? Or a heater? Very simple! The main thing is to know the internal structure of these devices in order to have an idea of its operation. After that, making a homemade construction is not difficult. The main thing is to remember to observe safety precautions when working with open fire or its sources.

General information

Around the middle of the 20th century, heavy fuel-powered autonomous heating boilers first appeared. Engineer Robert Babington received a patent in 1969 for a novel burner design that included an air atomizer. This feature guaranteed the heater’s maximum fuel combustion, superior efficiency indicators, and device safety. The original Babington boiler modifications were made to run on diesel fuel and were utilized for military applications.

Then, waste oil and other heavy petroleum products could be used because of the design’s modernization.

The Babington burner operates on a different principle than traditional oil boilers. Fuel is delivered via low-power pumps and nozzles, such as waste oil or other oil and air mixtures. Diesel or spent oil flows down a hemisphere’s working surface to form a thin layer. There is a tiny hole, no bigger than 0.3 millimeters, in the middle of the nozzle. A saturated fuel-air jet is created when compressed air is introduced through an aperture, allowing a portion of the surface to be separated from the oil film.

A strong and steady flame torch is created when the saturated fuel-air mixture is ignited. The fire is focused on the boiler or furnace, which heats the water jacket directly through the walls or through the coolant that is circulating inside. One or more fuel tanks for running out of fuel are located directly beneath the hemisphere. A pump is used to remove any extra waste and return it to the combustion chamber.

The used waste oil is further heated to increase burner efficiency while lowering fuel consumption. This allows for the following to be guaranteed:

• The heated fuel forms a thin film on the working surface, which is better atomized by the saturated air flow.
• The tiny droplets in the air jet are easily ignited, which subsequently improves the combustion performance of the heater.
• The fuel consumption is reduced, while the efficiency of the heating system is also increased.

Electric heating elements or additional heat removal from the burner itself can be used for fuel heating. In the first scenario, the boiler is energy-dependent and can only operate at its peak fuel and efficiency when connected to an electrical source.

Babington burner: subtleties in construction and use

Fabrication and testing of Babington burner nozzles

Is it possible to make a blowtorch run on waste fuel?

A traditional blowtorch works on the basis of igniting gasoline vapors that are forced outward by compressed air. Air is forced into the burner’s fuel tank to produce this effect.

What would happen if used oil was put into a blow torch?

Oil needs to be heated in order to evaporate, even when it is under pressure. Poor atomization will result in an uneven flame and make it challenging to light the burner. Oil burns and produces a lot of carbon deposits and soot, which causes the nozzle to stick quickly, reduce its cross-section, and eventually cause the lamp to fail. Increasing the nipple’s cross-section will also have the opposite effect of what is intended; the oil will atomize into large drops, making it impossible to get a consistent flame from the torch.

Furthermore, contaminants like water, diesel, gasoline, and antifreeze are frequently found in used oil and can result in internal lamp flashes. The task will become even more complex if you need to set up a filtration system in order to use waste as fuel for a blowtorch.

It is challenging and dangerous to use a gasoline blowtorch as a waste oil burner in light of all the challenges. As a result, its design needs to be enhanced or altered entirely.

Which gas to choose

A gas burner designed specifically for hand soldering uses fuels like these:

• natural gas;
• propane;
• butane;
• propane-butane mixtures.

Stated differently, on mixtures of hydrocarbons and atmospheric air. A temperature of two thousand degrees Celsius can be achieved through the use of 100% isobutane fuel.

Acetylene is a material that raises the temperature to a maximum of 3000 degrees Celsius. However, a number of factors make such an apparatus unpopular at the moment, including the requirement for continuous oxygen, the high degree of risk, the requirement to use costly calcium carbide for operation, and others.

It is more than possible to obtain hydrogen at home, and such a device can produce a temperature as high as 2500 degrees Celsius. But the initial ingredients required to produce this material—hydrocyanic acid is the primary mixture—are also highly costly. They’re risky as well. The odorous nature of hydrogen is another drawback.

Methane, for example, is not used in home burners for reasonably apparent reasons. The gas is extremely poisonous as well. Regarding methane vapors, they burn with a small flame and have an average temperature of 1100 degrees Celsius within the structure.

Nozzle

The first step is to create a spherical nozzle that will eventually hold fuel. Create a hole in the sphere that is roughly 0.25 mm in diameter.

Keep in mind that the diameter is influenced by the DIY burner’s power. The power decreases with decreasing diameter and vice versa.

You will face every challenge when creating the nozzle. The air passage channel needs to be made perfectly flat. The air must be beaten forward, not against the nozzle walls. Creating the hole using a specialized machine is the best choice.

However, if you are fortunate enough to locate a nozzle with the appropriate diameter, seize the chance and position it in the spherical element’s center. In the event that a hemisphere is not found, a tiny piece of sheet metal with an internal nozzle attachment can be used. You will thus receive an atomizing oil nozzle. It will be filled with warmed fuel, and the air coming in will cause atomization. Installing a device like this in a universal boiler provides an affordable and effective source of heat.

Waste oil burners present a viable option for homeowners looking for more environmentally friendly heating solutions. Used oils, like motor or cooking oil, can be recycled and used as energy by these burners to heat spaces. These systems lessen heating costs and their impact on the environment by recycling waste oil that would otherwise be disposed of. Waste oil burners can be a useful addition to any home looking to reduce its carbon footprint because they are adaptable and can be used with a variety of heating systems. These burners offer an effective and environmentally responsible solution for insulation and heating needs with the right upkeep and installation.

Babington burner with their own hands drawings and something else

As noted above, the fuel should flow along the curved surface, which is necessary for effective combustion. Many people use ordinary door handles. The first thing to do is to cut off the base, you can do this with an ordinary hacksaw. Then solder the copper adapter. Next, a source of gas is introduced or Pay a little attention to the cleaning of the surfaces. They should be well treated and preferably degreased. Sometimes hollow balls of different diameters, made of metal, are used in place of the handle. Large-diameter balls are more preferable, as they provide a fast fuel supply and create a thin film, and this is an advantage. In addition, the large ball has a larger hole

This is crucial if waste oil containing a lot of foreign objects is utilized. Consequently, choose the first option if you have to choose between a large and a small ball.

Peculiarities of burner manufacturing

One that is made by hand ought to be compact and look like a gas cylindrical. Metal sections of pipe are fixed to the body from both the top and bottom. They ought to be placed across from one another and secured with welding. To feed the oil-oxygen suspension into the compartment where combustion occurs, the lower section is necessary. A burner socket is located in the upper section. It shoots forth the flame torch with a high temperature. It is necessary to use a household vacuum cleaner with significant power in order to create air flow into the construction for flame formation.

Advantages of waste oil burners

Nearly any type of oil can be used with a waste oil burner, including diesel fuel, heating oil, compressor oil, motor, transmission, and working fluids with viscosities up to 90 SAE.

The following tasks can be completed successfully with the help of this equipment:

• Reliable provision of the cheapest possible source of energy;
• complete solution to the problem of utilization of used oil;
• absolute independence from interruptions of centralized networks and rising energy prices;
• possibility of connection with heating boilers and heat generators of any type and manufacturer;
• complete combustion of waste oil without emission of smoke and odors;
• environmental protection from uncontrolled mass release of used oil without its treatment and recycling;
• quick payback and high reliability of the equipment;
• excellent maintainability – all spare parts are available for periodic replacement and maintenance.

In technical spaces up to 900 m2, waste oil burners provide extremely affordable heating (previously waste oil was simply thrown away). Examples of these facilities include car service stations, railroad depots, aircraft hangars, workshops, and other spaces.

Device, principle of operation

The purpose of waste oil-powered universal burners is to initiate and sustain combustion. They are integrated into paint booths, heat generators, and water heating boilers.

Almost every liquid burner uses the same mechanism and working principle:

• a fuel pump pumps the fuel into a sealed combustion chamber, where it is heated to the temperature necessary to turn on the compressor;
• air from the room is mixed with fuel under pressure and this mixture is fed into the combustion chamber through a nozzle;
• with the help of a fan heated air is distributed in the room (in order not to appear during combustion soot, soot and smoke, fuel is pre-filtered).

Reliability is enhanced by the availability of automatic burner operation regulation in high-quality multifuel models. Even though the waste oil container is a little distance from the device, the pump can easily handle the supply of waste oil.

The fuel supply unit, also called a fispacket, consists of a floating fuel collector, a fuel filter, and a supply pump. Certain models—Kroll KG UB 20 or Kroll KG UB 55 fispaket, for instance—do not come with the basic delivery set and must be purchased separately from the compressor. However, most of the time, like with the Euronord EcoLogic 60, it comes pre-installed and has a fuel level sensor.
