The diesel heat gun is ideal for quickly heating a construction site, agricultural, warehouse or industrial premises. Since its operation is carried out on diesel fuel, it consumes electricity exclusively for the operation of automation and a fan. As the main advantages of such a technological solution, one can name a relatively high thermal power with rather small dimensions. The design of the heat gun contains the following main elements: a burner located in the combustion chamber, a fan engaged in forcing air, and a fuel tank.

Working principle

There are two types of units in this category: direct and indirect heating. In the first option, all exhaust, that is, exhaust gases, are inside the heated room. Notit is recommended to use such devices in residential buildings. An indirectly heated diesel gun means that the residues are removed to the street through an installed chimney. The room is exceptionally warm clean air. However, a prerequisite for the operation of such guns is the presence of high-quality ventilation, since oxygen in the room is heavily consumed during its operation.

Varieties

An indirectly heated diesel gun can have one of two design schemes. The first option is a device in which the burner elements are built into the body. The operation of a single axial fan provides air for heating, as well as oxygen required for the combustion process. A diesel gun of this type belongs to the category of semi-professional equipment. Its distinguishing feature is its sensitivity to fuel quality and voltage fluctuations in the supply network. Since only one fan is used for two air paths, any resistance in each of them can affect combustion and the operation of the device as a whole. Another scheme provides for the presence of a pair of fans: one provides a supply of clean air, and the second - the combustion process. Such a device is characterized by professional devices, the power of which starts from 50 kW. They are characterized by a long service life and maximum reliability.

Technical characteristics of diesel guns of indirect heating

This type of equipment usually hashigher power compared to analogues of direct heating. Any diesel gun is made of high-quality durable stainless steel, has a thermally insulating casing of the electric motor, and is also characterized by a resistant outer coating.

Indirect heating devices are focused on large rooms, characterized by high-quality air circulation. This type of device is capable of providing space heating, the area of which reaches 2200 square meters. In particular, the Master BV 690 E diesel gun is distinguished by just such an indicator. The approximate fuel consumption of such units varies between 1.44-18.5 l / h. At the moment, the main manufacturers of these devices are such companies as Master, BIEMMEDUE, Patriot Power.

Direct heating

Guns operating on this principle are designed for use in rooms with an area of \u200b\u200bno more than 500 square meters. In terms of operation, this type of device is as simple as possible. The output power can be 10-44 kW. Depending on the power, the weight of the units varies between 19-30 kilograms. The diesel gun of direct heating has a fuel tank, the volume of which depends on the dimensions of the device and can be 15-45 liters. Fuel consumption is 0.86-1.5 liters per hour. The fan is powered by an electrical network with a voltage of 220 or 400 volts. This type of diesel gun is produced by companies such as Master, Resanta, as well as Latvian and American companies.

Benefitsheat guns

Diesel-fueled equipment has a whole range of advantages. Since the device does not require connection to gas or electricity, it is distinguished by its autonomy and mobility provided by special wheels. With their help, the device can be moved to any place convenient for this. By using a diesel engine, high efficiency and productivity of the equipment is achieved.

Easy operation and absolute safety are achieved through the presence of a fumes cleaning system, a thermostat that prevents overheating, a housing that is completely isolated from the heating elements, and a stabilization system for the flame.

A diesel gun, the price of which is 40 thousand rubles or more, is designed to heat industrial premises, so you should not choose this device if you need to heat a house or apartment. As the main competitor of the gun in terms of heating large rooms, only one unit can be called - a heating solid fuel boiler. However, only a cannon can heat a really large room, as well as provide ventilation and air circulation.

Difficulties you may encounter when choosing

The thermal performance of the appliance must be selected depending on the total thermal power required to heat the room and guarantee the proper flow of technological processes. The required heat output is the calculateda value that depends on the average value of the winter temperature outside, the required temperature inside, as well as on the sum of the available heat losses. The last parameter depends on the material and thickness of the walls, ceilings, floors, sizes of gates and windows, and the performance of the supply and exhaust ventilation. These data can be determined from the design documentation of the building, for which a diesel gun will be used as a heating device.

Installation of the heater is allowed indoors or outdoors. The second option involves the mandatory organization of the supply of already heated air to the heated object. Most models of diesel guns have the ability to use them in combination with air distributors and air ducts.

Heating process

The speed with which the diesel gun will heat the room to the desired temperature depends on the flow of hot air. The more the heater is able to pass through itself, the sooner the heat will be distributed throughout the room. But here it is important to understand that it is impossible to increase the flow without increasing the power of the heater, and this entails an increase in fuel consumption.

Room heating speed

The diesel gun has one very important characteristic - the temperature difference between the intake and heated air. This parameter is directly dependent on the air performance of the device, efficiency and thermal power. The temperature of the intake air usually does not matter. ForFor most indirect heating appliances, the temperature difference is 50-70 degrees Celsius, and for direct heating it is 300-400 degrees.

Quite often, a diesel heating gun is used to maintain a certain temperature level in a room. This stability is achieved by installing controllers or thermostats that are connected to the control system. When using the equipment at low temperatures, it is required to provide heating of the fuel by 10 degrees above the cloud point. Therefore, diesel fuel is recommended to be stored in a warm room, as well as to use a special fuel heater.

If you need to move the diesel gun frequently, the right choice would be to purchase a mobile model with a set of wheels, as well as special devices for moving with a crane.

The subtleties of choosing a diesel gun

In the selection process, it is necessary to take into account the required performance of warm air for a particular room. The cost of the equipment is directly affected by the parameters of the device itself. When choosing diesel guns for space heating, you should take into account the power, dimensions, the absence of a chimney or its presence, the outlet air temperature, as well as other less important points.

It should be understood that a high level of performance in combination with maximum efficiency can only be obtained from a gun with direct heating. They should be installed where there is an opportunity for ventilation.premises, as well as with a high probability that people will not be there. For open-type premises, an indirect heat gun is well suited, as it is characterized by high power and demands for a large air inflow, which is sufficient in open air conditions. If you do not want to worry about turning off the device in winter, then you must choose a model with a heated filter element. In this case, even low quality fuel can be used.

Equipment through the eyes of the consumer: diesel gun

Reviews about this device speak in favor of the fact that this is the best solution for industrial and warehouse premises, where it is required not only to quickly warm up the entire volume of air, but also to maintain the temperature at the proper level. This equipment performs well not only in terms of high performance, but also fairly good fuel economy. It is important to understand that it is the diesel heating gun that is able to create the optimal temperature level in the overall room in the shortest period of time.
