Thermal diesel gun is an ideal option for quick heating of a construction site, agricultural, warehouse or industrial premises. Since her work is carried out on diesel fuel, she spends electricity exclusively on the operation of automation and a fan. The main advantages of such a technological solution can be called a relatively high thermal power with a rather small size. The design of the heat gun contains the following basic elements: a burner located in the combustion chamber, a fan engaged in air injection, and a fuel tank.
Principle of operation
There are two types of units in this category: direct and indirect heating. In the first embodiment, all exhaust, that is, exhaust gases, are inside the heated room. It is not recommended to use such devices in residential buildings. Indirect heating diesel gun implies that the withdrawal of residues occurs to the street through an installed chimney. The room turns out to be exceptionally warm clean air. However, a prerequisite for the operation of such guns is the availability of high-quality ventilation, since oxygen in the room is greatly consumed during its operation.
Varieties
An indirect heating diesel gun may have one of two design schemes. The first option is a device in which housing elements of a burner device are integrated. The operation of one axial fan provides air for heating, as well as oxygen required for the combustion process. This type of diesel gun 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 ducts, any resistance in each of them can affect the combustion and operation of the device as a whole. In another scheme, a pair of fans is provided: one ensures the supply of clean air, and the other a combustion process. Such a device is characterized by professional appliances whose power starts from 50 kW. They are characterized by a long service life and maximum reliability.
Technical characteristics of indirect heating diesel guns
Equipment of this type usually has more power in comparison with analogues of direct heating. Any diesel gun is made of high-quality durable stainless steel, has a heat-insulating motor casing, and is also characterized by a stable external coating.
Indirect heating devices are focused on large rooms, characterized by high-quality air circulation. This type of appliance is capable of heating rooms with an area of 2,200 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. Currently, the main manufacturers of these devices are companies such as Master, BIEMMEDUE, Patriot Power.
Direct heating
Guns working on this principle are oriented to use in rooms with an area of not 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 direct heating diesel gun 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 operates from an electric network with a voltage of 220 or 400 volts. This type of diesel guns is produced by such companies as Master, Resanta, as well as Latvian and American companies.
Benefits of Heat Guns
Equipment running on diesel fuel has a whole range of advantages. Since the device does not require binding 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 convenient place for this. Through the use of a diesel engine, high efficiency and productivity of the equipment is achieved.
Simplicity in operation and absolute safety are achieved due to the presence of a system for purging from flue gas, a thermostat that protects against overheating, a housing that is completely isolated from heating elements, as well as a stabilization system for the flame.
The diesel gun, the price of which is from 40 thousand rubles and above, is intended for heating industrial premises, so you should not choose this device if you need to heat a house or apartment. In terms of heating large rooms, the main competitor of the gun is only one unit - a solid fuel heating boiler. However, only a cannon is capable of heating a truly dimensional room, as well as providing ventilation and air circulation.
Difficulties you may encounter when choosing
The thermal performance of the device should be selected depending on the total thermal power needed to heat the room and guarantee the proper flow of technological processes. The required heat capacity is a calculated value that depends on the average value of the winter temperature outside, the required temperature inside, as well as the sum of the available heat losses. The last parameter depends on the material and the thickness of the walls, floors, floors, dimensions of gates and windows, the performance of supply and exhaust ventilation. These data can be determined from the design documentation of the building for which the diesel gun will be used as a heating device.
Installation of a 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 diesel gun models have the option of using them in combination with air diffusers and air ducts.
Heating process
The speed with which the diesel gun warms up 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 rate
The diesel gun has one very important characteristic - the temperature difference between the taken and warmed air. This parameter is directly dependent on the air productivity of the device, efficiency and thermal power. The temperature of the intake air is usually not relevant. For most devices of indirect heating, the temperature difference is 50-70 degrees Celsius, and for direct - 300-400 gr.
Quite often, a diesel heating gun is used to maintain a certain temperature level in the room. This stability is achieved by installing controllers or thermostats that are connected to the control system. When using equipment at low temperatures, it is required to provide fuel heating 10 degrees above the cloud point. Therefore, it is recommended to store diesel fuel in a warm room, as well as use a special fuel heater.
If you need to frequently move the diesel gun, the right choice would be to purchase a mobile model with a set of wheels, as well as special devices for moving through a crane.
The subtleties of choosing a diesel gun
In the selection process, it is necessary to take into account the required productivity of warm air for a particular room. The cost of the equipment is directly affected by the parameters of the device itself. If you select diesel guns for space heating, you should take into account the power, size, absence or presence of the chimney, the temperature of the air at the outlet, as well as other less important points.
It should be understood that a high level of productivity in combination with maximum efficiency can be obtained only from a gun with direct heating. They should be installed where there is an opportunity for airing the premises, as well as with a high probability that people will not be there. Indoor heat guns are well suited for indirect heat guns, as they are distinguished by their high power and exactingness to a large air supply, which is sufficient in open air conditions. If you do not want to worry about turning off the device in the winter, 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 of this device speak in favor of the fact that this is the best solution for industrial and warehouse premises, where it is necessary 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 pretty good fuel economy. It is important to understand that it is a diesel gun for heating that can create the optimal temperature level in the overall room for the shortest period of time.
