The principle of operation of various types of diesel heat guns. Diesel heat gun: principle of operation, review of the best models and reviews Features of direct heating diesel heat guns

Essential in any space comfortable temperature conditions, but it is not always possible to provide this.

To solve the problem with heating, there is an option to use heat gun which works on diesel fuel, has small dimensions and is easily moved to the right place.

Also, these devices are convenient for use in the construction process, for example, for space heating where the installation of stretch ceilings takes place.

In a simplified form, the design of the heat gun is as follows set of components:

• fan;
• a heating element;
• fuel tank;
• frame.

Cannon work provided by the combustion of fuel, the heat obtained from combustion with the help of a built-in fan forms a stream of warm air that fills the space around.

However, such guns differ in the way they are heated. He happens two kinds: direct and indirect.

The differences between these methods are only that devices with a direct type of heating, together with warm air products of combustion enter the room fuel mixture such as soot and smoke. Heaters that operate in an indirect type need to be equipped special sleeve for removal of products of combustion and a flue.

Important: all heat guns are mainly powered by a 220 V network. The rate of heating the room depends on what air performance the device has.

Diesel heat gun repair

In case of malfunctions, it is better to contact a specialist, but there are such breakdowns that can be repair on your own:

1. After turning on the heater, it immediately turns off.. This can happen if any of the filters, the nozzle through which fuel is supplied or the combustion photo sensor is dirty, or the air supply pressure sensor is illiterately configured. The same problem may be due to the connections between the photosensor and the control panel board. The photo sensor reacts to the presence of light, therefore it is cleaned and the connections are checked for integrity and correct connection.
2. The device does not turn on, or the engine does not run for long. There may be several reasons for this failure. Low fuel level in the tank, as well as corrosion and clogging on the electrodes, or the presence of moisture in the fuel tank.
3. Fan idle when on. First of all, check the thermostat setting, which may be set too low. If this is not the reason, then check the electrical connections printed circuit board and engine. In the absence of such, the connections are restored.
4. weak flame. Such a malfunction is corrected by adjusting the level of thermal power.
5. Heat generator stopped working. This problem is caused by a blown fuse that needs to be replaced.
6. Equipment overheating. The reason for this is faulty wiring and it is possible to eliminate the malfunction only by replacing it. It is permissible to turn on the equipment only after it has cooled down, but it is recommended not to postpone a full repair.

As a rule, with the onset of the cold period of the year, the problem of heating premises for various purposes sharply arises.

And this applies to both private residential buildings and industrial premises different type. In such cases, the heat supply from the central heating system is expected. But what about when central heating still not working or not at all in the room?

In such situations, one usually tries to use alternative sources heating, which can safely be attributed to such a type of units as heat guns.

The modern market for heating equipment has enough wide range of heat guns various kinds. But special place this range is occupied by diesel.

To have an idea about this type of thermal units, in this article we will talk about what diesel heat guns are, what characteristics they have, and also where they can be used.

What are

Diesel heat gun is a kind of heating unit, whose main purpose is to quickly and economical heating such non-residential premises as production workshops, agricultural storage facilities, construction sites And so on.

A distinctive feature of this type of heat guns is that the thermal air flow is formed as a result of the combustion of liquid diesel fuel.

Advantages of application

The use of diesel heat guns for household purposes carries a number of positive and indisputable points, which are undoubtedly associated with the following advantages of this type of unit:

• excellent performance characteristics;
• simple maintenance;
• depending on the type, the power of diesel heat guns varies from 20 to 230 kW;
• enough economical consumption diesel fuel;
• opportunity to work in offline more than 10 hours;
• good functioning of the unit at low temperatures;
• perfectly heat large areas.

Based on the positive aspects of the diesel heat gun, we can safely say that it is effective device for space heating.

Kinds

Diesel heat guns are usually divided into two main options:

• aggregates direct heating;
• indirect heating units.

Consider the principle of operation of each of these types of heat guns.

direct heating

The principle of operation of a diesel heat gun is as follows:

As you can see, the principle of operation of a diesel heat gun with direct heating is quite effective and understandable.

But the unit of this type has one significant drawback: together with the air heat flow, the combustion products of diesel fuel also enter the room.

In this regard, the following requirements are imposed on the use of diesel heat guns:

• the use of this type of unit in residential buildings is prohibited;
• the room where the heat gun works must be equipped with a good ventilation system;
• with the help of this type of unit, it is allowed to perform all work operations, without exception, in open areas.

indirect heating

The principle of operation of a heat gun with indirect heating is almost the same as the previous type.

However, this type of unit has a significant advantage: the exhaust products of combustion are removed outside the premises through a specially equipped chimney. Thus, heat guns with indirect heating can be effectively used in residential premises, provided that proper ventilation is provided.

Converting direct heating to indirect

In order to understand this issue, you need to turn again to the design of these types of heat guns.

If in units with direct heating, the combustion products come out with warm air, then this means that the combustion chamber is of an open type.

In a heat gun with indirect heating, emissions are removed using a nozzle, so the combustion chamber is presented as a closed heat exchanger. Consequently, the process of converting a direct heating heat gun into an indirect one consists in replacing the combustion chamber, as well as equipping the unit with an outlet pipe.

But here the obvious question arises about the effectiveness and cost of such a method of technical alteration of the heat gun, which remains open.

The lineup

Despite the fact that heat guns are rather narrow-profile equipment, nevertheless, on modern market these units are represented by many manufacturers.

After analyzing the products of manufacturers of heat guns, we have identified a number of the following most popular models:

Thus, we introduced you to all the characteristics of diesel heat guns, indicated the features of different types, and also provided a list of the most popular heat guns. We hope that the above information will greatly help you when choosing a heat gun.

Watch a video in which a specialist talks about the device and types of diesel heat guns:

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 because they can work 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.

Choice the best option heat gun should be based on the following factors:

1. Rent or buy. If the frequency of its use is low, then it is best to rent a convenient model.
2. Power. The maximum possible heating area directly depends on this parameter. it is possible by a simple ratio 1 kW = 10m ².
3. Possibility of venting combustion gases outside the premises. It is worth considering in advance the location of the gun and the installation of pipelines through which gases will be removed outside the building.

The device of the unit includes a metal case, which is able to protect the structure from various damages. Heating parts are fireproof. All models are lightweight, which allows them to be moved anywhere.

Diesel structures are often in demand in the construction of various facilities. They are used when necessary to quickly dry the surface. Liquid-fueled designs are of indirect and direct heating. The first method is to withdraw flue gases from the premises. The operation of such devices is accompanied by the burnout of oxygen, so they are used on outdoors or in well ventilated rooms.

How to choose a diesel heat gun?

Keep in mind that combustion products are expelled when starting a diesel-fuelled heat gun. Manufacturers offer two types of such devices: direct heating and indirect heating.

When choosing a design, the following factors are important:

• area of ​​the room;
• availability of fuel raw materials;
• the ability to withdraw harmful impurities, and ventilation;
• how it will be operated: permanently or periodically.

Diesel units contain a burner, combustion chambers, a fuel tank and a fan. Some products are equipped with wheels for ease of movement. Fuel is supplied by a pump.

Helpful information! When choosing a model, in the calculations, rely on the following indicators. For 10 sq. m. will need about 0.9-1.5 kW.

The nuances of choosing a direct heating diesel heat gun

heat gun on diesel fuel has a simple direct heating mechanism. Inside the product there is an electric motor and a fan. Using pumping unit fuel is delivered to the furnace tank. The burner is mounted inside the body, so there is no open fire.

When burned out, the diesel fuel warms up the air masses, which are removed from the fan. Heated air is distributed in space. And the smoke masses diverge into the inside of the building. Therefore, such devices can be used outdoors or in buildings with a good ventilation system.

Note! Such models are suitable for short-term work. For example, dry work surface at construction work or warm up a frozen engine.

How to choose an indirect diesel heat gun?

In indirect heating installations, in addition to the main elements, there is also a heat exchanger. The fuel moves from a special tank to the furnace tank. At the same time, the flue gases do not mix with the air masses from the fan, but exit through the chimney structure to the street.

When the device is turned on, the heat exchanger warms up and heats the air. At the outlet, such devices can emit from 50 to 110 degrees of heat. This technique is used in manufacturing and warehouses, as harmful gases do not pass inside. AT modern equipment furnace tanks are made of stainless steel.

Some appliances are equipped flexible hoses, allowing to release a warm stream to a certain area.

Helpful information! A thermostat can be connected to the equipment, which is mounted inside the building. At the same time, the equipment will be able to maintain the required temperature and will produce heat for about 17 hours.

Models of infrared diesel heat guns

The installation of an infrared diesel heat gun does not include a fan heater. Such heaters do not heat the atmosphere, but the surrounding objects with the help of infrared radiation.

Burner with diesel feed warms up infrared emitter, which heats surfaces and objects in the room. silent, as their device does without a fan.

Model overview

To decide which heat gun is better gas or diesel, a review of the prices of individual models will help.

How to calculate the power of the equipment?

An important factor influencing the preference for a particular product is power. This figure is in the range from 20 to 220 kW. To calculate the unit with what power you need, you need to calculate the volume of the room. For this, the height, width and length of the walls are determined. You should also know the quality of the thermal insulation. This coefficient will differ for non-insulated brick and wooden buildings, as well as in buildings with high thermal insulation. To carry out calculations, it is worth determining the difference in temperature values ​​​​inside and outside the building. In this case, the power of the device is calculated as follows, the volume of the room is multiplied by the temperature difference and the thermal insulation coefficient.

Models of heat guns on waste oil will be an excellent solution for heating any room.
