Appearance

It takes into account such nuances as aesthetic appeal, achieved through the use of two basic shapes - rectangular and cylindrical, as well as high-quality paint and unit dimensions. If the device is planned to be used exclusively for domestic purposes in a small room, then a compact heater, the mass of which is 5-10 kilograms with dimensions in the range of 25-50 centimeters, is the best option. If there is a need to purchase a unit of greater power, then you should be prepared to transport equipment, the weight of which will be 50-150 kilograms with dimensions of 1-3 meters for each of the parameters.

Description of species

direct heating

The direct-acting unit operates according to the following scheme:

• the user pours diesel fuel or purified kerosene into the container, turns on the unit and sets the desired air heating parameters;
• the fan starts, as well as the fuel module; after that, diesel fuel begins to be supplied from the tank to the nozzles, where it is mixed with air;
• in the form of a fine dispersion mist, a warm air mixture enters the internal combustion chamber and is ignited using an electric glow plug;
• the photocell of the electrical circuit detects the ignition of the fire and after a few seconds the controller turns off the ignition electrodes;
• the main volume of the air mixture, as it were, washes the walls of the chamber from the outside, after which the heated air from the muzzle of the gun comes out; at this moment, a smaller part of the total air volume is burned and emitted as exhaust gases.

If the burner goes out, for example, after the liquid fuel runs out, the photosensor works again and sends a command to the control unit.After that, the latter immediately stops the pump, and after 15-20 seconds the equipment turns off. Combustion can spontaneously turn off if the thermostat fixes the heating of the surrounding space to the desired level. As soon as the room cools down, the burner will start working again.

However, along with the heat, soot enters the room, as well as an unpleasant smell. That is why the scope of use of such devices is limited to open areas where people are very rare.

indirect heating

Such a design assumes a closed combustion chamber, as well as a chimney, which will allow spent fuel exhaust to be removed outside the heated space. Fan heaters of this group have a slightly different principle of operation, namely:

• the combustion chamber is covered on all sides, the refractory plate is hermetically fixed and, in fact, becomes the front panel of the furnace
• the air is heated exclusively by the outer wall of the chamber;
• all combustion products through the upper pipe are brought out;
• the thermal gun must be connected to the chimney.

The removal of exhaust gaseous substances makes it possible to use this unit for heating enclosed spaces with poor ventilation.

However, we draw attention to the fact that it is still not worth heating residential areas with such a gun, since they do not have a draft sensor, as well as automation that can protect people from waste. The efficiency of indirect heating units is slightly lower, it does not exceed 60%, but they can be used in greenhouses, as well as on livestock farms

How to choose?

Usually diesel heat guns are bought when electric or gas ones are not suitable for some reason.

The maximum power of the guns reaches 200 kW, which is a great value. They can be used in large industrial facilities. However, these models also have several disadvantages. They are quite expensive, and they also have high fuel consumption.

There is also an important requirement for good ventilation, because the exhaust of these devices is powerful.

When choosing a device, you need to pay attention to several nuances:

1. heating type. Diesel guns of indirect heating are very similar to gas installations. Fuel is supplied to the nozzle and burns in the chamber. Air is blown into the room, heating it. Only in this case the chamber is closed, which increases the efficiency of the device. But its cost is almost 2 times more than that of gas models.
2. Fuel used. Most heat guns run on diesel fuel and kerosene. But there are devices that need only a specific type of fuel. If you use diesel fuel, then more harmful substances are released into the atmosphere.
3. The heating power indicates how much heat can be obtained from the gun. The larger this value, the faster it can bring the temperature to the desired value. This indicator also depends on what area can be heated.
4. Warm air capacity gives you an idea of ​​how much warm air passes through the unit.
5. Possibility to adjust the temperature. That is, when a certain value is reached, the device turns itself off. For this, a thermostat is installed on it.
6. Power consumption. This parameter is relevant in order to understand how much electricity will be spent during the use of the installation.
7. Fuel consumption and tank capacity.

Where do you use indirect diesel heat guns?

In the garageIn stock

The air temperature near the diesel gun can reach 400 degrees at the outlet. This means that combustible elements must be at a distance so that an explosion or fire does not occur.

Thus, it is necessary to choose the installation, taking into account all these nuances. It must meet the requirements. It is recommended that you read the specifications before purchasing. But not always the user has sufficient experience. Then you can designate a specialist budget and tasks. He will provide a choice of several models that are able to cope with them.

Advantages and disadvantages

Despite the fact that the modern industrial market offers a fairly wide selection of a wide variety of heating appliances, diesel guns have been in consistently high demand among consumers for many years. This is not surprising: despite the fact that the cost of similar electric and gas units is much lower, nevertheless, the operation of diesel equipment due to the low price of fuel is ultimately much cheaper. The list of advantages of diesel heat guns does not end there. Among the advantages of the equipment are the following:

• high efficiency parameter - even taking into account the need for regular ventilation and installation of supply ventilation, the diesel gun heats up the air space very quickly;
• ease of use - to activate the system, you just need to direct the gun nozzle to the very center of the room and turn it on;
• safety of operation - the most modern models of guns are equipped with all kinds of temperature controllers and photo sensors, which completely eliminates overheating of the device; in addition, the risk of accidental extinction of fire is reduced to zero;
• mobility - the diesel heat generator is quite compact and has a small mass; so, a device with a power parameter from 10 to 20 kW weighs about 10–12 kg, so there are no difficulties with its transportation;
• economy - a little fuel is needed to warm up a non-residential premises; for example, a unit with a power of 22 kW and a tank size of 15–20 liters spends no more than 2.5 liters of fuel per hour.

However, it was also not without drawbacks. Among them are the following:

• life-threatening fumes of kerosene and diesel fuel; however, this problem is usually solved with the help of an established ventilation system and chimneys;
• often users mention an increased noise level that irritates the ear; this is true - diesel guns cannot be attributed to silent devices, although the presence of such sounds is considered natural for any heater;
• some users are not satisfied with the dependence of equipment on the mains; the gun needs constant power to maintain the functionality of the pump and fan;
• some note the high cost of equipment, but it should be noted that the price of heat guns is fully offset by their durability, practicality, simple operation system, and economical fuel consumption.

Criterias of choice

Heat guns

The direct duties of heat guns include heating both residential and industrial premises.And this means that far from always the device is necessary to satisfy only the needs of a person in a comfortable temperature. Many technical facilities require maintaining the temperature for the safety of the goods or carrying out certain work.

Based on this, it becomes clear that the choice of this unit is a very important process that must be approached with all responsibility and care, and such an impressive number of different models only complicates the task. Therefore, in order to be guaranteed to choose a worthy model, you must adhere to the following criteria and selection rules:

Thermal gun

If a heat gun with direct heating is used, then at the time of operation of the tool, people should not be in the room without special protective equipment. Indeed, during the working process, hot air and gaseous combustion products (smoke, fuel vapors, and so on) are released into the atmosphere. Being left without adequate protection puts the airways, eyes and other exposed areas of the body at risk.

By and large, the internal structure of a diesel-powered gun, called an indirect heat generator, is almost identical to the direct-fired guns, also running on diesel. The only difference lies in the types of combustion chambers - for units with indirect heating, the chambers are closed, and for devices with direct heating, they are open. At the same time, functionally, guns with indirect air heating are much more attractive because all the spent combustion products do not enter the room, but are brought out into the street.

Features of the repair of diesel guns for space heating

Repair maintenance of a diesel-fueled plant can result in a significant amount of money. Only one diagnostic procedure costs about 1000 rubles. For this reason, many owners of garages and storage facilities resort to self-repair of structures.

How to repair a diesel heat gun yourself

If warm air does not move, the fan motor may be defective. Repair involves stripping the terminals, checking the winding on the motor (an analog tester is suitable for this), as well as insulation. Sometimes the damage is so serious that a superficial adjustment is not enough.In such cases, one thing remains - replacing the engine.

An important part of the design are nozzles. The quality of the work of these elements depends on the full functioning of the entire heating system. These parts rarely break, and you can buy new elements to replace failed ones at any store.

These parts rarely break, and you can buy new elements to replace failed ones at any store.

Modern heat guns are equipped with a convenient control panel that allows you to adjust the air heating temperature.

Much more often, the need to repair a diesel gun arises due to filter clogging. To eliminate this breakdown, it is enough to open the body of the structure, unscrew the plug and remove the contaminated element. After washing with pure kerosene, the filter is ready for further operation. Before installing this part in place, it is advisable to blow it out with a jet of compressed air.

Rules for the safe operation of diesel appliances

At operation of diesel appliances it is very important to adhere to the basic safety requirements. A container filled with fuel must not be placed closer than 8 m from sources of open fire and any heating devices. Important! Do not use gasoline instead of diesel

Volatile components of this substance increase several times the likelihood of an explosion.

Important! Gasoline instead of diesel is not allowed. Volatile components of this substance increase several times the probability of an explosion. A room with a working cannon must be left at the first appearance of these symptoms:

A room with a working cannon must be left at the first appearance of these symptoms:

• severe dry mouth;
• pain and discomfort in the nose and throat, as well as the eye area;
• headache that appeared suddenly;
• nausea.
