Pyrolysis boiler with your own hands

Are you trying to find a cost-effective and environmentally responsible way to heat your house in the chilly winter months? In that case, creating your own pyrolysis boiler could be the ideal answer. Pyrolysis boilers use biomass energy to produce heat, making them a sustainable substitute for conventional heating techniques. We’ll discuss the idea of pyrolysis heating in this article and walk you through building a homemade boiler.

Through the process of pyrolysis, organic material is heated without the presence of oxygen, producing biochar and other byproducts as well as syngas, a flammable gas. Pyrolysis boilers can effectively turn biomass—such as wood chips, sawdust, or agricultural waste—into heat energy by using this process. Compared to fossil fuels, this renewable energy source has several benefits, such as lower operating costs and carbon emissions.

You can alter the design of a pyrolysis boiler to meet your unique heating requirements and resource constraints by building your own. With the flexibility of do-it-yourself construction, you can customize the size and features of your boiler to suit your needs, whether you’re looking to heat a larger residential property or a tiny cabin. Building your own boiler can also be a satisfying do-it-yourself project that gives you a sense of control and accomplishment over your home’s heating system.

Although the thought of creating a boiler from scratch may seem overwhelming, you can be confident that it’s a task that can be completed with the correct support and tools. We’ll guide you through the entire process of building a pyrolysis boiler in the sections that follow, from locating supplies to putting the parts together. Our thorough instructions and advice will help you confidently navigate the process, regardless of your level of experience with do-it-yourself projects or your lack of familiarity with home construction.

Principle of operation

Without knowing the fundamentals of how they work, it is hard to evaluate the benefits of pyrolysis boilers. First of all, what exactly is pyrolysis?

In essence, it is the breakdown of organic materials in the presence of very little air. Wood burns at 900–1200 °C in a typical boiler with adequate air flow. Burning one stack of firewood releases 4900 calories of heat over the course of three to four hours.

Table 1: Calorific value of various wood species used as firewood

The pyrolysis boiler breaks down solid fuel into solid sludge and gas while it burns at a temperature between 300 and 850 degrees Celsius. The flammable (pyrolysis gas) reacts with carbon and undergoes further processing in the absence of oxygen in a different chamber, increasing the thermal conductivity as a result.

As a result, during the pyrolysis process of dry distillation, solid sludge is burned alongside solid fuel at the same time as pyrolysis gas. All of this results in a single wood stack burning for up to 12 hours (as opposed to the typical 3–4 hours) and an efficiency increase of the boiler to 85–90% from the typical 65–70%.

Pros and cons of the equipment

Positive and negative traits are present in every unit. To make an informed decision, they need to be sufficiently evaluated.

• maintenance of a certain combustion temperature in automatic mode;
• Increased burn time of the tab on the background of increased efficiency of the boiler;
• Possibility to use various types of solid fuels, up to wood and agricultural products.

Using more than one-third of the total fuel polymers and rubber is not advised.

• large dimensions of the boiler due to the enlarged combustion chamber;
• special requirements for solid fuel – wood must be completely dry

Even a 25% moisture content in the fuel slows down the gas emission process, lowering the coolant’s temperature and decreasing efficiency.

• energy dependence – during operation, the boiler consumes electricity for the operation of the fan, creating a forced draft, and automation;
• the price is the most important disadvantage that makes you refuse to buy it.

For this reason, we suggest that you build a pyrolysis boiler yourself using the instructions, blueprints, and working principle found later in the piece.

Boiler device

The primary distinction between the standard and pyrolysis boilers is that the former has one combustion chamber, while the latter has two, separated by a grate. The fuel and solid residue burn in the lower combustion chamber, while the pyrolysis gases burn in the upper one. Such a layout of the furnace chambers enables process optimization, longer fuel combustion times, and increased efficiency.

Photo 2: Pyrolysis boiler schematic diagram

Pyrolysis is a process that can only occur in environments with restricted airflow, where fuel smolders instead of burning, producing more gas.

The features of the pyrolysis boiler include the reaction of carbon with the pyrolysis gas and increased aerodynamic resistance in the chimney as a result of the lack of air. An electric fan provides forced draught; in fact, pyrolysis boilers fall under this category of energy-dependent machinery because of this.

The cost of a homemade model

The primary motivation, of course, is to manufacture the pyrolysis boiler by hand, searching for operating principles and drawings—banal economy. In the regions, a ready-made boiler typically costs between 36,000 and 37,000 rubles. (10 kW power, 100 sq. m.) to 140 000 rubles (38 kW capacity, 300 sq. m.). It is possible to save between 500 and 1500 u.е. in the independent boiler manufacture, but this comes at the cost of personal labor and materials.

Either way, this kind of work cannot be characterized as cheap or simple, so before attempting to construct a pyrolysis boiler yourself, evaluate your skills, go over all the drawings, and choose the precise materials that you’ll need.

How to make a pyrolysis boiler

• electric arc welding and 3-4 packets of electrodes;
• drill;
• small bolgar (circle 230).

The process of manufacturing with your own hands

A guillotine is the only tool that can cut metal perfectly straight; a bolt cutter can never produce such a cut. Saving money on metal cutting is not worth it because it can be costly.

1. Buying metal sheets and pipes at the metal depot, arrange in advance to cut them into the necessary fragments. In the future it will significantly reduce the time and give the opportunity to get even seams.

Picture 7: Metal cutting

1. From two parts start to assemble the boiler chambers – combustion and gas chamber

1. When both chambers are made, weld the air vents and the wall to the back of the chambers. In the photo for convenience, the channel is made of channel, but you can also make it from a profiled pipe 60×30, for which pre-cut small ventilation holes.

1. In the furnace chamber you make a hole for the air pipe and weld a spigot to it. Please note that this pipe must be connected to the boiler with a profiled pipe 20×20.

1. Manufacturing of a tubular heat exchanger – on the workpiece you cut several holes for a pipe D57 mm.

1. The D57 mm pipe is cut into pieces of equal size, which are then placed on the plate and welded around the perimeter.

1. Then the heat exchanger is welded by arc welding to the boiler and the throttle valve is made

1. The front wall is welded onto the chambers, where 2 holes are pre-cut – for the inlet and outlet air pipe

1. Next, the cover is welded on and a hog is welded in place of the damper

1. Assembled all the internal stuffing of the boiler, after which it is necessary to carefully clean the welding places with a bolgar or metal brush.
2. The outer casing on the boiler is made of 4 mm sheet and angles

1. In order to fasten the outer casing to the corners, small holes should be made in the workpiece. Each of them should be welded so that the sheet and the casing are qualitatively connected

1. Checking the tightness of the boiler with water – close the holes for the movement of the coolant with plugs and fill it with water. If it leaks in some place, make a note to reweld this place at once. The boiler must be completely airtight

1. The top cover should be additionally insulated

1. Threaded rods will be needed to regulate the operation of air dampers

1. The boiler is completely closed with an external casing, and a water drainage pipe is made of a profiled pipe.

1. The hinges are welded on and the door is put on. It is better to make it from cast iron plates, and use bricks for lining (protection from damage).

1. The lower chamber is also lined with refractory bricks – they should be cut and shaped so that the chamber is tightly fitted

1. In order for the boiler to meet the declared capacity, the damper in the lower chamber must meet certain parameters. When laying bricks, be sure to take it into account

1. A blast fan is welded onto the duct pipe (from profile pipe) to create a forced draught in the boiler

1. The lower chamber is also bricked up to make it as safe as possible and to optimize the combustion process.

1. To improve the operation of the boiler it is recommended to make turbo swirlers, on the one hand they improve heat transfer, on the other hand – clean the pipes from deposits.

1. Before starting the pyrolysis boiler, it is necessary to check how tight the seams are, using the same principle as in point 13 (see the following steps).above). But at the same time with water, it is necessary to create a pressure of 3-4 bar. You can use a special pressure tester for this purpose – when the pressure is increased, watch how quickly it decreases. If it"s fast – it"s leaking somewhere, look for it. If stabilized – everything is fine.

1. Be sure to install on the boiler safety group, which includes a pressure gauge, emergency pressure relief valve and air outlet. If the pressure increases above 3 bar, there will be an automatic reset.
2. In order to maximize the safety of the boiler and make its operation problem-free, it is recommended to install an automation unit. To find out how it works and why you need such automatic control, see the video instructions

Video 2: Pyrolysis boiler automation

First start

• When starting the boiler for the first time, connect it to the chimney and fill it with water

It is strictly prohibited to test a boiler that is empty and without a thermometer.

• In the lower chamber put paper and on it literally 2-3 logs (a lot to check the boiler is not necessary), close the chamber tightly and open the throttle door. When the fan is on, light the paper.
• When all the wood has taken up fire, the damper closes to allow the fuel to start smoldering ("languishing"), at which point the pyrolysis process begins to work
• In the lower chamber, check when the combustion flame lights up. As soon as it lights up, mark the time for which the coolant will almost boil over.
• When the heat transfer medium reaches 100C, turn off the fan, the torch will also immediately go out.

Conclusion, reviews, tips

As you can see, building a pyrolysis boiler by hand is a costly and time-consuming project that won’t yield results for three to five seasons. In any event, it is advantageous since it is possible to make equipment that matches a specific room in addition to saving money on materials.

Pyrolysis boiler with their own hands

Boilers with gas generators and pyrolysis are commonly used to heat both residential and commercial spaces. Their work operates on a somewhat different principle than standard solid fuel models. Nonetheless, the device’s more intricate design offers many benefits and reduces the amount of money needed for heating.

Principle of operation and device of the pyrolysis boiler

The boiler is the fundamental component of any heating system. The boiler’s job is to heat the fuel-infused coolant before transferring it to the heating system. Pyrolysis boilers are among the most affordable and promising types of domestic boilers.

A type of solid fuel boiler called a pyrolysis boiler typically uses water heating and allows the fuel and any volatile materials to burn separately. Gas-generator boilers are another name for these boilers.

Pyrolysis is the process by which wood burns and breaks down into gas and solid residues like coal. Two prerequisites need to be fulfilled in order for the two processes to occur:

• high temperature;
• lack of oxygen.

A unique design found in pyrolysis boilers provides the required conditions. The firebox of such apparatus is split into two sections. When there is not enough oxygen in the loading chamber (first section), the fuel burns and pyrolyzes. Secondary air enters the combustion chamber (second part), where the released gases have completed burning. The main loading chamber’s heat dissipation is reduced by this design.

The fuel is placed on a grate that divides the two compartments. One distinguishing feature of boilers of the pyrolysis type that sets them apart from other heat-generating devices is the air supply, which flows through the fuel from top to bottom. Since the firebox increases aerodynamic resistance, forced draught arrangements are common. Usually, either a blast fan or a smoke pump is utilized.

The following is the order in which long-burning pyrolysis boilers operate:

1. Firewood (or other fuel) is placed on the grate and set on fire.
2. After closing the door, the smoke pump is started.
3. Under the action of high temperature (up to +800°C) charring takes place and wood gas is released.
4. The released products (carbon monoxide, hydrogen, hydrocarbons and nitrogen) flow under the grate.
5. Blowdown is added to the pyrolysis products – volatile substances are gradually burned, and part of the heat is returned to the layer of firewood located below.
6. Heat is used for heating heat carriers – air, water.

Advantages and disadvantages of pyrolysis boiler

The following benefits have made pyrolysis boilers more popular:

1. Complete combustion of fuel ensures economical combustion. In addition, this quality allows for less frequent cleaning of the ash pan and gas ducts.
2. Adjustable combustion process allows you to increase the duration of combustion of one furnace (about 12 hours).
3. Emissions of harmful substances into the atmosphere are reduced – the high temperature in the chamber from above suppresses CO.
4. Large, not chopped firewood is suitable for the furnace.
5. The possibility of full automation of the boiler and connection to any heating system.
6. The boiler can utilize rubber, plastics and polymers without polluting the environment.

Crucial! Boilers with gas generators are more energy-efficient than boilers without one. The equipment’s power can be adjusted between 30 and 100%, and the pyrolysis boiler has an efficiency of up to 85%.

The following can be linked to pyrolysis boiler drawbacks:

1. Large size of the plant.
2. Boiler efficiency decreases sharply if fuel with high humidity is placed in it.
3. Energy dependence of the boiler – without a smoke extractor the unit will not work.
4. At low loads (less than 50%) unstable combustion and tar in the gas ducts are observed.
5. It is impossible to organize an automatic supply of firewood.
6. High cost of pyrolysis boilers. You can save money if you make the boiler yourself. But the manufacture of the boiler – a fairly complex process that requires accurate calculations, drawing development and competent assembly.

Fuel for pyrolysis boiler

Firewood or fuel pellets work better for pyrolysis boilers. Wood that is 400–450 mm long and has a diameter of 100–250 mm can be loaded. The fuel briquettes measure 300 by 30 mm. Sawdust and small wood waste can be burned alongside firewood, but the total volume of the loading chamber should not exceed 30%.

When using dried wood, the boiler runs as efficiently as possible. Furthermore, this condition enables you to prolong the installation’s lifespan.

One kilogram of wood with a 20% moisture content burns for four solar kWh, while wood with a 50% moisture content burns for two.

Wood tar that has been liquefied can be used as pyrolysis oil in industrial settings. Although the material has a high calorific value (about 40,000 kJ/kg), the metal and lining are badly impacted by the strong acidic reaction of the pyrolysis oil. It is therefore undesirable to use it in residential boilers.

To make or not to make a pyrolysis boiler on your own

Boilers that use pyrolysis are efficient and modern, but they are also costly. A basic domestic boiler should cost no less than $1,000. Imported gas generator units are priced an order of magnitude more.

Making a pyrolysis boiler yourself or having the installation manufactured by experts is a feasible option. Although the second option will be more expensive than the first, depending on the size of the boiler, it will be able to save a significant amount of money in comparison to buying new equipment.

Picture of a homemade pyrolysis boiler

Of course, it would be inaccurate to describe the boiler’s assembly as being entirely inexpensive and easy. Prior to building the apparatus, you should evaluate your own skills and knowledge and read up on all the details regarding the boiler’s components and operation.

Development of the drawing and calculation of the pyrolysis boiler

It’s crucial to adhere exactly to the pyrolysis boiler’s developed drawings while operating. This is a sketch of the most widely used self-assembly design. The heater has a 40kW design. The internal volume of the device cannot be altered, but its design can.

A – circuit controller for boilers;

B is the loading door;

C is the door to the ashtray;

E is the thermal fuse sensor (R 1/2) coupling;

F is the emergency system spigot (a safety valve is installed in the supply line beside the safety group assembly using a tee);

G – boiler circuit supply line;

H: the protective heat exchanger’s cooled water supply, R ¾;

K is the safety heat exchanger’s hot water supply, R ¾;

L is the boiler circuit return line;

M: the emptying pipe and expansion tank.

A private home typically only needs a 40 kW boiler. Larger or smaller capacity installations require corresponding adjustments to the boiler’s other parameters. The efficiency and longevity of the installation are ensured by the pyrolysis boiler’s proper size ratio.

Table showing the compliance of the pyrolysis boiler with the produced output

Crucial! A boiler that can produce between 25 and 30 kW of heat will be the best choice for a small home. The production of small equipment will reduce assembly costs and time.

Understanding the internal structure of the boiler will be aided by the 3D visualization of the connections between each boiler unit.

Putting the boiler into operation

The boiler needs to be filled with water and connected to the chimney before it can be started. To regulate the coolant’s temperature, the boiler needs to have a thermometer. Boiler designs include holes for installing thermometers.

Here is the order in which the pyrolysis boiler system is turned on:

1. Connect the fan to the power supply and check its operation. Set the air dampers to the center position.
2. Put paper in the gasification chamber and place a small amount of firewood on top of it. Close the gasification chamber door.
3. Open the chimney damper, turn on the fan and ignite the paper.
4. When the wood is well heated, the chimney flap must be closed.
5. Control of the ignition of the combustion flame of pyrolysis gases is done through the lower combustion chamber.
6. Flame intensity/color can be adjusted by moving the flame damper. When the boiler is properly adjusted, the flame is yellow-white in color.
7. Note how long it takes for the water in the boiler to boil over. When the temperature reaches +100°C, switch off the fan. After this, the torch will go out, and the water will begin to gradually cool down.

Pyrolysis boiler with their own hands: drawings, schemes

Each and every home in areas far from central heating used to have a solid fuel boiler. Both wood and coal are used to heat it. Regretfully, there were drawbacks to this design as well. The primary issue was using’s inconvenience.

Pay heed. Electric heaters are installed quite frequently, but it’s important to understand that using them to heat a home is an expensive endeavor.

Fortunately, a worthwhile substitute that you can construct yourself is a pyrolysis boiler. This article will provide an overview of the primary plans and illustrations. These kinds of devices can generate heat through the burning of wood or specialized briquettes. Furthermore, waste from factories that produce wood can be used.

What is a pyrolysis boiler

How it works

You can comprehend the fundamentals of the pyrolysis heating system’s operation by looking at its schematics and drawings. However, in order to make this device with your own hands, you must gain a deeper understanding of it.

Dry distillation is essential to the operation of the pyrolysis boiler process, which is manually constructed in accordance with the blueprints and schematics provided in the article. The decomposition process starts when the temperature reaches 500–600 degrees Celsius. Two products come from it: natural coke and gas.

Atoms of oxygen are combined with the gas produced inside the structure. The combustion is initiated by this. Naturally, the chamber that you constructed with your own hands in accordance with blueprints and schemes needs to be at the right temperature for everything to work as planned.

Carbon comes into contact with pyrolysis gas, which is produced in the boiler by hand. This in turn sets off a response. However, the device needs to be made precisely in accordance with plans and drawings in order for this to be feasible.

Smoke is produced as a byproduct of the pyrolysis process, which is carried out in a long-burning boiler by hand in accordance with widely used drawings and schemes, but it is free of dangerous substances. As a result, there is not much environmental damage.

The fact that the pyrolysis boiler was constructed by hand in accordance with blueprints and designs has the significant benefit of almost completely eliminating waste output. This results in the release of a significant amount of heat energy, which heats a sizable area.

The process of pyrolysis is classified as exothermic. All processes that release heat are generally referred to by this name. However, not everything is that easy. The truth is that this heat is required to achieve further fuel heating and drying.

Advantages and disadvantages

Before you become an expert at the pyrolysis boiler, there are some crucial details that you should understand based on schematics and drawings. Let’s begin by discussing the benefits and drawbacks of the design.

The following benefits of homemade pyrolysis boilers can be attributed to:

• Maintaining the set temperature of the heating medium for a long period of time.
• Large volume of the feed chamber.
• High efficiency.
• The possibility of utilization of woodworking waste in a pyrolysis boiler made according to drawings.

However, the fuel had to contain no more than thirty percent of additional components in order for the handcrafted pyrolysis boiler to function as required.

Every design has drawbacks, and in this instance those are as follows:

• large dimensions,
• dependence on network availability,
• Demanding fuel.

The high purchase cost of the pyrolysis system is another factor contributing to its drawbacks. However, it can be greatly decreased if you build the device by hand using blueprints and sketches.

Undried wood cannot be placed in the pyrolysis boiler that was constructed by hand in accordance with the plans and drawings. The key point is that high humidity prevents the pyrolysis reaction from occurring. The efficiency falls off quickly, even at a tiny percentage. This is as a result of heat energy being transformed into vapor.

The requirement that the device have a fan explains why it needs to be connected to the network. He is the one who gives you permission to provide a forced-draught pyrolysis boiler that you made yourself using blueprints and designs.

Constructing a DIY pyrolysis boiler can be an enjoyable and economical approach to heat your house with the least amount of negative environmental impact. By utilizing the process of pyrolysis, you can transform waste biomass into useful thermal energy and lower your carbon footprint and heating costs.

The adaptability and customization possibilities of a do-it-yourself pyrolysis boiler are among its main benefits. Based on your individual heating requirements and the resources at your disposal, you are free to select the size and design of your boiler. You can modify your boiler to effectively burn biomass fuels like wood chips, sawdust, or other materials to generate heat for your house.

In addition, you can take charge of your heating system and lessen your dependency on conventional fossil fuels by building your own pyrolysis boiler. You can contribute to the fight against climate change and local air pollution by using renewable biomass materials.

However, it’s crucial to proceed cautiously and pay close attention to safety when building a pyrolysis boiler. Adherence to safety protocols and meticulous planning are imperative when handling combustible materials and elevated temperatures. To reduce the possibility of mishaps and guarantee the safe and effective operation of your do-it-yourself boiler, make sure you study and abide by best practices for boiler design, construction, and operation.

In conclusion, building a pyrolysis boiler with your own hands offers a sustainable and cost-effective solution for heating your home. By harnessing the power of pyrolysis, you can convert waste biomass into valuable heat energy while reducing your reliance on fossil fuels. With careful planning and attention to safety, you can enjoy the benefits of a DIY pyrolysis boiler and contribute to a cleaner, greener future for generations to come.
