Heat guns on diesel fuel: device and principle of operation

As homeowners, we’re always looking for new and inventive ways to keep our homes comfortable, particularly in the winter. One creative remedy that is becoming more and more popular is the use of diesel-fueled heat guns. These gadgets provide an effective way to heat areas, such as a garage, workshop, or even an entire house.

Making educated decisions about adding these heat guns to our heating systems can be facilitated by having a thorough understanding of their operation and guiding principles. Diesel-powered heat guns have distinct advantages over conventional techniques like wood stoves or electric heaters in terms of portability, efficiency, and affordability.

Diesel heat guns fundamentally work on a straightforward but efficient principle. They use diesel fuel, which is ignited inside the apparatus to produce a great deal of heat. After that, the heat is dispersed via a nozzle or heat exchanger, giving you exact control over the warmth’s direction and temperature.

The combustion chamber, which produces heat by igniting diesel fuel mixed with air, is one of the main parts of these heat guns. Heat is released during combustion and is subsequently carried into the surrounding air. The gun’s nozzle allows the heated air to be released, sending a constant stream of warmth in all directions.

Diesel heat guns are flexible and convenient, whether you’re looking to add to your current heating system or need a flexible heating solution for a particular space. Their capacity to swiftly elevate the temperature and their lightweight design make them perfect for a range of settings, including outdoor gatherings and construction sites.

How to choose?

The rate at which the room heats up is the first thing to consider when purchasing a heat gun. For instance, an 80 kW gun would be required for a 150 m² room. Additional attributes comprise the subsequent:

• thermal insulation of the housing – heating of the surface of the device during operation should not be more than +40 degrees Celsius;
• mobility – it is best to give preference to models with wheels;
• noise emission – keep in mind that the more powerful the fan of the equipment, the louder the sounds will accompany its work;
• option to adjust the heating – it is desirable that the equipment was supplemented with a button or handle, with which each user can independently set the necessary parameters of the thermostat;
• battery operation – if you plan to use the gun in conditions where there is no electricity, it is worth choosing a model that works from a storage unit; as practice shows, even a car battery is enough to achieve uninterrupted operation for several hours;
• when buying, be sure to ask about the overheating protection system: many manufacturers offer it as an additional device to maximize the safety of work; optimally, if the gun will be equipped with an automatic system to control the degree of heating and the option to turn off the equipment at overheating.

Basics of selecting diesel heat generators

The power output of a heat gun determines both how quickly it heats up and how big of an area it can cover, just like other heating appliances. However, aside from this crucial feature, there are additional subtleties that you should be aware of in order to make the best decision possible when purchasing a device.

Determining the required power of the device

The fuel consumption and heating speed are not the only factors that affect the heat gun’s power. Additionally, it is advisable to estimate the volume and presence of thermal insulation in the room that will be heated with a diesel heat generator before making a purchase, even though all technical specifications are included in the unit’s accompanying documentation. A small 10 kW gun can typically heat up to 100 m2 at a ceiling height of no more than 2.5 meters, but you can use a specific formula for more precise calculations.

The following algorithm can be used to determine the device’s heat output:

1. Calculate the volume of the room in m3 by multiplying the values of its width, length and height in meters.
2. Determine the difference between the outdoor temperature and the temperature required for the room.
3. Multiply the volume with the temperature difference and the heat loss coefficient.
4. And the last step is to convert the value from kcal/hour to the usual kW. To do this, you need to divide the obtained figure by 860.

The building’s level of thermal insulation and the materials used in its construction will determine the coefficient’s value:

• "cold" structures made of wood or metal will have an index of 3 to 4;
• Buildings with minimal insulation, one brick masonry and primitive roof construction – from 2 to 2.9;
• buildings with medium thermal insulation with double masonry, standard roofing and small glazing area – from 1 to 1.9;
• rooms with double-glazed windows, double brickwork, insulated walls and roof – 0.6-0.9.

Let us examine the algorithm’s performance in real-world scenarios. For instance, a metal hangar with a 150 square foot area, a height of 4 meters, and a temperature of +18 °C needs to be heated. In the winter, the outside temperature is typically ten degrees below zero.

67200 kcal/hour = (150 m2 * 4 m) * 28 °C * 4 = 860 = 78.14 kW

In other words, devices with a capacity of 80 kW and above should be considered when selecting a heat gun model. You can use the information in the table, which illustrates the relationship between the properties of heat generators and various building volumes while accounting for a 30 °C temperature difference, to estimate the power of the device.

And in this case, the fuel consumption indicator is highly conditional even though it appears to be a crucial parameter. No matter how advanced it is technologically, the appliance will only use as much fuel as is required to heat a specific building, depending on the temperature you choose, the size of the space, and the caliber of the thermal insulation.

Other important nuances

Once you have selected the two most crucial parameters (power and heating method), you should consider additional features.

For instance, given that nearly all guns have the shape of an elongated cylinder, a detail like the shape initially appears to be purely a "matter of taste." However, it is preferable to select rectangular units from high power devices because the heated air flow is distributed over a greater area with these units. Rectangular cannons with multiple nozzles can process a lot of air quickly, which makes them popular for drying building materials and setting up simultaneous heating for multiple rooms.

Additional technical characteristics

1. Thermal insulation of the case – the surface temperature of the device itself should not exceed 40 degrees Celsius during operation.
2. Mobility – it is convenient when the device is equipped with a wheeled base, but lightweight guns up to 22 kW can be mounted simply on a stable base. In this case, it is worth paying attention to the weight of the set, material and strength of the tray.
3. Noisiness – the more powerful the fan of the device, the louder will be the "musical accompaniment" during its operation.
4. Ability to adjust the temperature – the device should be equipped with a knob or button, with which you can independently program the thermostat parameters.
5. Battery operation – if the object is not connected to the power grid, you can choose a gun that operates from a storage tank. Electricity consumption of the device is low (mainly power supply is required for the fan), varies within 100-500 W/h, so even a car battery is enough for uninterrupted operation for several hours in field conditions.

Additionally, it’s important to find out if a safety mechanism against overheating is included when making a purchase (some manufacturers offer it as a separate device). The gun should have an automatic heating level control system and a fuel-sense shutdown mechanism for safe operation. Fuels like gasoline, acetone, fuel oil, and alcohol are not allowed to be used with direct heating guns as they can damage the device and cause a fire or fuel vapor explosion.

Another crucial detail to discuss with the equipment seller is the kind and specifications of the suggested fuel. GOST 305-82 specifies that "winter" automobile DT or clarified (aviation) kerosene should be used with most diesel guns.

You can make your own heat gun if buying one is not an option. Read on to learn what you’ll need for this.

Calculation of the minimum required power

The following formula is used to determine an electric heat gun’s power:

• V – volume of the room (it can be found by multiplying the area by the height), m3;
• T – indicator of the difference between outdoor and indoor air temperature, oC;
• K – the coefficient of thermal conductivity, it depends on the type of insulation of the room: 3-4 – for simple metal and wooden uninsulated structures;
• 2-2.9 – buildings with simple single brickwork and simple roof and window construction;
• 1-1,9 – buildings with double brickwork, a small number of windows, average thermal insulation;
• 0.6-0.9 – buildings with double thermal insulation, insulated windows, walls and roof.

Consider this instance. For a 24 m2 garage with good insulation and a 3 m ceiling height, we must select a heat gun. The volume will be 72 m^3, or -24 * 3. The temperature inside is +15°C, while the outside is -20°C. There is a -35оС temperature difference. This is how the calculations will appear:

P is equal to 72*35*1 = 2520 kcal/h.

Since 1 kW = 860 kcal/hour, this value must be divided by 860 in order to convert it to kilowatts.

860 = 2.93 kW is 2520.

Therefore, the heat gun’s power requirement should be at least 3.5 kW and no less than 3 kW if a power reserve is included.

Shape and size

The lightweight, compact design of electric heat guns falls between 3 and 30 kg. This is a portable device that is easy to move around.

The gadget may have a rectangular or cylindrical shape. Because the first version’s heat energy is dispersed over a bigger surface area, it is better suited for indoor work.

Rectangular forms work better for spot heating because they have unique mesh heaters.

Duration of operation

A continuous operation mode is present in most models. They are able to run continuously for extended periods of time. Typically, the technical specifications provide a value of 24/1 or 24/2.

This indicates that the device operates without interruption for one or two hours each day.

In our article about heat guns running on diesel fuel, we"ll dive into how these devices work and what makes them effective for heating homes. Diesel heat guns operate by burning diesel fuel in a combustion chamber, which generates heat. This heat is then transferred to the surrounding air via a heat exchanger and blown out through a nozzle or duct, distributing warmth throughout the space. The principle behind their operation is simple: diesel fuel is ignited, producing hot gases that heat up the air passing through the heat exchanger. This heated air is then directed where it"s needed, efficiently warming up the environment. Understanding the device and its operation can help homeowners make informed decisions about heating their houses effectively and efficiently.

Wiring diagram for the heat gun

There are many different types of heat gun designs, but the electric heating gun design is the most straightforward and safest. A substantial air flow strikes the heating element when the fan is operating. A thermostat is used to set the desired temperature for the air during heating. Depending on how the heat gun is made, its housing may be able to rotate.

On a horizontal surface, the angle is selected in both directions from the main axis. The unit starts working after it is connected to the mains and the light indicator lights up. The appliance is started by a switch, i.e. by setting it in a certain position. The required output is selected with another switch. In the electrical circuit has a special thermal switch, which completely disconnects the heat gun from the network when the temperature of the body exceeds 100 degrees Celsius. The use of this gun is optimal in cold or moderate climates. The humidity of the room must not exceed 80 percent. Do not allow the electric heat gun to get wet. The climatic conditions of the room must allow for reliable and safe operation of the unit.

Starting up and safe operation

Usually, the units arrive partially disassembled. That is, you will have to install the handle (or metal arches) and fix the gun’s "muzzle" on a wheeled cart. If the gun uses direct heating, all that needs to be done is fill the fuel tank, plug it into the electricity grid, adjust the heating temperature, and flip the power switch. The gun’s integrated thermostat ensures that it will shut off when the air temperature rises and restart when it drops, saving fuel and avoiding overheating.

Make sure the following safety precautions are followed before operating the equipment:

1. The gun is installed on a stable and level horizontal surface made of non-combustible materials, such as concrete. If the floor is made of wood, sheet metal can be placed under the unit.
2. The distance from the nozzle from which the hot air flow will be supplied to the nearest object is at least 2 meters (on the right and left it is desirable to maintain a distance of 80-100 cm).
3. Before the first start-up or after long storage it is recommended to open the casing and manually check the fan impeller to make sure that it rotates freely.
4. The unit will "signal" the need for refueling by intermittent combustion or emission of white smoke. To refill the fuel, be sure to disconnect the heat gun from the power supply.
5. Always turn off the gun with the toggle switch and wait for the fan to stop completely. For indirect heaters, this process may take 2-5 minutes, but is necessary to cool the combustion chamber. Only then can the plug of the appliance be pulled out of the mains supply.

Installing a chimney, which is a round pipe made of non-combustible material with a maximum length of three meters, is a prerequisite before turning on the diesel indirect heater. Flexible aluminum corrugation is a convenient option if a long-distance outlet is needed, but it will need to be replaced multiple times during the heating season.

A much longer-lasting option is to use a section of steel pipe to connect to a nearby vent. The indirect heating gun’s chimney path should be laid out in a straight line with a maximum of one 90-degree bend.

In terms of maintenance, cleaning the combustion chamber of soot and dust and washing air filters on a regular basis are essential for the trouble-free operation of diesel heat generators. Maintaining the cleanliness of the unit’s interior around the nozzle and engine is also crucial.

Device	Principle of Operation
Heat guns on diesel fuel typically consist of a fuel tank, a combustion chamber, a heat exchanger, a fan, and a nozzle.	When diesel fuel is sprayed into the combustion chamber and ignited, it creates a flame that heats the heat exchanger. The fan then blows air over the heat exchanger, heating it up. This hot air is then directed out of the gun"s nozzle, providing warmth to the surrounding area.

Diesel-fueled heat guns are a practical and economical way to heat spaces, especially in places where electricity might not be easily accessible. These gadgets work on a straightforward principle, producing heat through combustion. They generate hot air through the burning of diesel fuel, which can be used to heat up commercial, industrial, or residential areas.

The actual device is made up of a few essential parts, such as a fuel tank, nozzle, fan, and combustion chamber. The diesel fuel is ignited after being mixed with air and pumped from the tank into the combustion chamber. Heat is produced during combustion and is subsequently transmitted to the air moving through the chamber. This heated air can be directed to the desired area for heating with the assistance of the fan, which helps to circulate it.

The adaptability of heat guns running on diesel fuel is one of their benefits. They can be used for a variety of tasks, such as defrosting frozen pipes, drying out damp areas, and heating construction sites and warehouses. They are a popular option for short-term heating requirements, like those during construction projects or outdoor events, due to their portability and comparatively simple operation.

However, when utilizing heat guns powered by diesel, it’s crucial to take safety precautions. When used improperly, they carry the risk of carbon monoxide poisoning or fire because they involve combustion. Regular maintenance is required to ensure safe and efficient operation, and proper ventilation is crucial to prevent the buildup of fumes. To reduce risks and maximize performance, users should also abide by the instructions and suggestions provided by the manufacturer.

In conclusion, heat guns that run on diesel fuel offer a practical and efficient way to heat areas in which electricity might not be available or practical. These devices generate hot air by using combustion energy, which can be directed to warm different types of environments. Despite their portability and versatility, users must put safety first in order to prevent any potential risks related to their use. Diesel-powered heat guns can be useful instruments for preserving comfortable temperatures in a range of settings with the right use and upkeep.
