Diesel thermal gun: device, pros and cons, opportunities. Diesel heat guns and their varieties Diesel infrared guns

For heating hangars, awnings, sports and exhibition halls, structures of agro-industrial and livestock complexes, as well as other large industrial and construction facilities for various purposes, heat gun. It is a mobile powerful air heater. A special heating element is installed in the gun body, which heats up to a high temperature. The air passing through it, pumped by the built-in fan, enters the room with a powerful high-temperature air stream. The combustion chamber is made of heat-resistant alloy steel. through the diesel heater of large air flow. The wear-resistant outer coating of the gun body is designed for long-term operation of the diesel air heater.

Depending on the heating method heating element There are 4 types of heat guns:

- heat guns diesel;

Heat guns gas;

Heat guns without power regulation;

Heat guns direct heating.

Available in two types diesel heat guns : direct and indirect action.D diesel thermal cannon direct action can be used for air heating only when there are no people, animals, etc. in a heated room. This requirement is due to the fact that the air repeatedly passing through the heat gun loses oxygen and becomes saturated with its combustion products.

Air heaters indirect heating are distinguished by the absence of emissions of combustion products into a heated room, and can be used in places where people are located. Diesel guns indirect action have special heat exchanger, which provides a withdrawal harmful emissions outside the heated area, while in working room clean heated air is supplied. Powerful indirect air heaters operating with diesel fuel, have a burner flame control system. For achievement complete combustion fuel, a mechanism for regulating the flame torch is provided. Also, all units are equipped with protection against overheating. Automatic maintenance of the set temperature is provided by a built-in thermostat, which is equipped with most models of diesel air heaters.

diesel heat gun, enough fuel, in non-stop operation, for 8-16 hours, depending on the model and the volume of the fuel tank.

Diesel heat gun during operation, it creates a powerful directed jet of hot air, the temperature of which at the outlet reaches 255 degrees (depending on the model and type of product). The heat transfer process of the air heater occurs almost instantly. High performance and forced circulation air when using a heat gun allow you to quickly heat up and maintain the desired temperature in a large room.

Rapid heating of the room is possible with the help of special thermal equipment. In addition to stationary devices, there are also mobile thermal stations. Their principle of operation is based on the creation of a powerful heat flux, which in a short time raises the temperature in the room to the required value. Such a need may arise during construction and repair work, to comply temperature regime in production.

by the most popular view such equipment are heat guns. Depending on the type of energy carrier, they can be gas, electric or diesel. The latter are the most popular, as they can work in offline. But when a diesel engine is running, exhaust gases and combustion products are released. In order to protect the people in the room, we have developed special kind diesel gun with indirect heating.

Structurally, it is a movable platform, in the lower part of which there is a fuel tank and a supply system to the upper cone chamber.

With the help of a pump, the fuel is metered into the combustion chamber, which is located in the main cone according to the "pipe in pipe" type. The small chamber is completely isolated from external environment, except for the withdrawal system carbon monoxide. In the process of burning diesel fuel, the walls inner chamber heat up. At the same time, the fan starts to work, which creates an air flow passing over the surface of the inner chamber. In the process of its movement, heat from the walls is transferred to the moving air and further into the premises.

The advantages of such an operational heating system:

1. High rate of temperature rise.
2. Long operating time without refueling - up to 10 hours.
3. Independence from the presence of the main heat carriers - gas, electrical network with plenty of power.
4. Mobility.
5. Possibility of installation.

The main characteristics for these heating devices are:

• Thermal power - 21 to 220 kW.
• Tank volume and fuel consumption in various operating modes.
• The area of ​​the heated room. This parameter is given without taking into account the height of the ceilings and the area of ​​window structures.
• The volume of air flow for 1 time.

Despite their narrow focus, there are many manufacturers on the market that offer different types heat guns running on diesel fuel.

As such a replacement, you can buy an indirect diesel heat gun with suitable characteristics.

The device and principle of operation of a diesel heat gun

The heat gun is a universal device for space heating. The principle of operation of such structures is quite simple: diesel burns inside the heater, as a result of which heat is generated, which is supplied to the room by a powerful fan.

Diesel fuel is used as fuel. Some models are able to run on used and filtered oil or kerosene. Thanks to the progressive internal device these designs have high power and coefficient useful action, which reaches almost 100%. All diesel heat guns are dependent on electricity. Some low-power modifications can operate on 12 V or 24 V, but most models for normal functioning 220V required.

Electricity is used to start the burner. In addition, it is necessary for the transport of heat due to the rotational movements of the fan. The burner not only atomizes the fuel, but also contributes to the air supply. As a result of this process, a mixture is formed that is highly flammable. Thanks to this, the flame is stable.

Affordable price of diesel guns and the possibility efficient heating premises without central system heating, made these designs so popular. This type equipment is capable of generating a large number of heat, thereby expanding the scope of its application.

Important! Solar powered guns cannot be used to heat residential areas.

Scope of diesel structures:

• heating of warehouse type premises;
• backup heating at poorly insulated facilities in cases where frosts uncharacteristic for the area occur;
• heating of construction sites where heating has not yet been installed;
• organization of heating in hangars used for storage of equipment;
• installation of stretch ceilings;
• heating of greenhouse structures used for growing crops.

In addition, you can buy an indirect heating diesel gun to organize heating in the garage.

Why is it profitable to buy a diesel gun: design advantages

Guns that heat rooms by burning diesel fuel have many undeniable advantages. They are compact in size and light in weight, while they have excellent technical specifications. These designs are easy to use. The mechanism is launched with just one push of a button.
The user has the ability to control the temperature in the room.

Many diesel designs have a built-in system for connecting a rheostat. The principle of operation of this mechanism is very simple. Before launching the gun, it is enough just to set the required parameter. When the room temperature reaches this value, the automatic shutdown equipment. When the temperature drops below the level of the specified mark, the structure will start on its own.

Diesel guns are economical, fuel consumption depends on the technical parameters of the device. Equipment with a power of 20 kW and a capacity of 550 m³ / h will need about 1.5 liters of diesel fuel to warm up this volume. Using such a gun, you can achieve quick results. According to the manufacturer's information, diesel devices heat up the room instantly. The air temperature of +10°C in a room with a volume of 120 m³ can be raised by a gun to a level of +180°C in 15 minutes. And this speed is not the limit.

Diesel devices are safe to operate. If the room is well ventilated, the inhalation of burnt air does not cause such unpleasant consequences as headaches and dizziness. Quality constructions are able to work in a long mode without additional refueling. The guns are equipped with tanks of large volumes, thanks to which they are able to work continuously throughout the day.

Note! The body of the structure is heated to a temperature of + 30-35 ° C maximum. Therefore, accidentally touching the gun will not cause burns.

Disadvantages of using diesel heat guns for a garage

The customer reviews left about diesel heat guns for the garage not only reflect the advantages of these designs. Sometimes they also have shortcomings that were identified by users during the operation of the device.

Often mentioned high level noise as a serious hearing irritant. Although the presence of sounds is considered normal for heating equipment. Guns do not belong to the category of silent devices. Some manufacturers offer models with reduced operating noise levels. For example, the Master BLP 15M diesel heat gun produces no more than 20 dB. This figure is considered very low.

Many users find the dependence of appliances on the electrical network inconvenient. The gun does need power for the fan and pump, and there is no way around these requirements. However, most often such structures are used at facilities where there is electrical wiring.

Among the shortcomings is also mentioned high price diesel heat guns. However, it should be noted that the cost of such devices is fully justified by their reliability and comfortable operating system. Many people are concerned about the cost of diesel fuel, which is more expensive to buy than liquefied gas in balloons. Although the fuel consumption of these devices is small.

How to choose a heat gun according to technical parameters

One of the most important technical parameters any heat gun is the level of its performance. In the characteristics, manufacturers indicate the number of kilowatts that the gun is capable of delivering in intensive operation. You can also calculate the performance level yourself.

An average power of 1 kW is enough to heat an area of ​​10 m², provided that the ceiling height does not exceed 3 m. This indicator is conditional, since it depends on the operating conditions of the room that needs heating.

Factors that affect heating efficiency:

• wall thickness;
• availability and quality of insulation;
• condition of the ventilation system;
• heat leakage (frequency of opening gates or doors);
• number of windows and doorways, their size;
• outdoor air temperature;
• the condition of the floors;
• wind strength, etc.

The price of an indirect diesel heat gun is not an indicator of quality. When choosing a device, it is advisable to pay attention to powerful modifications. The higher this figure, the better. If there is a lot of heat, you can always reduce the intensity of work. And if there is a shortage of heating, you will have to buy another device, which will significantly affect the budget. For efficiency diesel heater the place of its installation also has an effect.

Useful advice! AT large rooms it is advisable to use several heaters. Arranging appliances diagonally will be more effective than placing them along a wall.

Cold air is always heavier than warm air, so it always accumulates in the lower part of the room. Based on this, it becomes clear that installing the gun on a hill or turning its working edge up does not increase the heating efficiency. The most optimal position of the equipment is horizontal.

The performance of thermal ventilation equipment is another parameter that you should pay attention to. For an indirect heating diesel gun Ballu BHDN-20, this figure is 500 m³ / h. This means that the device is able to effectively heat the specified volume of air within 1 hour.

Last but not least are the dimensions and weight of the structures. The mass of heat guns can vary between 3-30 kg. Most of them have a mobile design, so they are easy to use. The smaller the device, the easier it is to move.

Features of direct heating diesel heat guns

Direct heating guns are the simplest devices that can serve as heat sources. Such structures have open chamber combustion. A pump equipped with a nozzle is installed inside, due to which a torch effect is provided. Behind these elements is a fan. All the heat that is generated in the process of fuel processing is supplied to the room along with the products of its combustion.

1. Diesel fuel from the tank is fed into the heating filter.
2. The compressor transports fuel to the injector.
3. The diesel fuel is ignited by the glow plug.
4. A fan mounted behind the burner captures cold air from the room to the combustion chamber, where it is heated.
5. The protective grid located in the front of the device delays the flame, preventing it from penetrating outside the combustion chamber housing.
6. After heating, the air is fed back into the room.

Features of indirect heating diesel heat guns for the garage, prices and reviews

This type of gun functions in much the same way as direct fired designs. The only difference is that the products of combustion, which are formed in the process of fuel exhaustion, are removed outside the room. For this, a chimney is used. Thanks to this, indirect heating guns can be used in almost any room with a sufficient level of ventilation.

In construction closed chamber combustion nozzle installed. In addition, the gun has a system designed to remove combustion products. The air blown by the fan does not come into contact with the torch. Its heating is provided by blowing the combustion chamber.

Average prices for diesel heat guns of indirect heating:

Useful advice! Define thermal power space heating appliance can be used with this formula: Q (in kcal/h) = K × V × ΔT, where Q is required level heat output, K is a coefficient reflecting the degree of heat dissipation, V is the total volume of the room, and ΔT is the difference between the outdoor temperature and that required to create a comfortable indoor microclimate.
