Thermal gun on diesel fuel: the principle of operation, review of the best models and reviews

Heat guns are most often used to provide targeted heating. Their feature is the high power in the supply of air masses of a certain temperature. This is due to the widespread use of this equipment in the construction industry and industry. Properly selected heat gun on diesel fuel is able to perform concrete heating, maintain optimal microclimate in the production room, and protect plants in the greenhouse from hypothermia in the winter.

The principle of operation of heat guns

The organization of the working process in any heat gun provides for the possibility of activating the fan, which ensures the supply of air. In this case, this task is realized at the expense of energy generated in the combustion chamber of diesel fuel. In the design of the unit is provided a tank for pouring diesel fuel or kerosene. Through a special filter the mixture enters the sump, and then the pump pumps it into the nozzle for further use. Usually at the rear of the equipment there is a fan that feeds cold air masses into the combustion chamber, distributing diesel in it from the injector. In the end, there is a combustion of fuel, and already hot masses are sent to the target object. Under this scheme, a general principle of operation of a thermal gun on diesel fuel is constructed, but there are also some differences in the process, depending on the design features of a particular model. At least, there are fundamental differences in the operation of two types of such installations - with direct and indirect heating. It is worth to learn more about these types of heat guns.

Varieties of heat guns

Models with direct heating differ in that in the process of work, the combustion product is directly released into the exploitation zone - this can be, for example, a production room or a construction site. Modifications with indirect heating provide for the removal of combustion products beyond the boundaries of the working object. Obviously, direct heating has serious limitations in terms of use. In particular, such equipment can not be used in living quarters. In exchange for this inconvenience, the user receives higher performance.

In turn, the heat gun on diesel fuel indirect heating can be used in the premises where people are. Its design includes a mechanism for removing combustion products, which interfaces with the chimney channel through a special branch pipe. That is, in the process of working, heat flows get rid of burning, spreading around the room or shop in a relatively pure form. True, the operation of such models requires the organization of a ventilation system in the room, since the unit will process oxygen.

Main characteristics of the equipment

Among the main technical and operational parameters of thermal guns, it is worth noting the power, volume of delivered air and fuel consumption. As for power, this figure is in the average corridor from 10 to 80 kW. For residential premises, installations with a power potential of 15-25 kW are usually purchased. The industry uses more productive units with a capacity of about 200 kW. In order to ensure future savings, one should also take into account the volume of the combustible mixture, due to which the diesel thermal gun will work . The fuel consumption varies on average from 1 to 6 l / h. The higher the power, the more voracious the heat generator. Depending on the area of the room, the volume of warm masses that the installation will distribute will also be selected. This figure can be 200 and 3000 m ³ / h. For a living room there will be enough installation with an initial value of volume, and production facilities, warehouses and construction sites are serviced by high-performance heat guns.

Especially the combination of the performance of this model and the presence of a system for removing exhaust gases are distinguished. In other words, it is a thermal cannon on diesel fuel, which absorbed the dignity of domestic and industrial units of this type.

Reviews of the Jumbo 200 M from Ballu

If you need a high-performance gun, then you should contact the Jumbo 200 M from the Italian manufacturer of climate technology Ballu. This heat generator is oriented to the maintenance of large areas. According to the owners, the installation performs drying of warehouses, production halls, cellars, etc. for small periods of time. Of course, if necessary, the equipment can also be used as a heating system. It is important to note the reliability of the model. The fact is that the most frequent malfunctions of the heat gun on diesel fuel are associated with the burner and the fan. Designers have increased the strength characteristics of these parts, so criticism about the reliability of the Jumbo 200 M installation is practically not found. In addition, many emphasize the benefits of safety and limit thermostats, which increase the safety of the operation of the equipment.

How to choose the best option?

Consider not only the nature of the intended purpose, but also the dimensions and the need for additional functions. You can build on the strength and performance indicators. This will help determine the principle of the gun - with the withdrawal of spent combustion products or without it. In accordance with the size of the room, the dimensions that a thermal cannon can have on diesel fuel are determined. It is not difficult to install this unit with its own hands, but in the case of models that provide for the evacuation of gases, it may be necessary to equip the structure with nozzles and adapters for the chimney. It will also not be superfluous to calculate in advance the need for electronic control systems with the control of a heat gun.

Maintenance advice

Most heat generators work in an intensive mode, which increases the importance of technical measures for their maintenance. Mainly the user should take care of regular cleaning and replacement of filters. In particular, the air filtration element, which filters out fibers and fluff, should be updated every 500 hours of operation. As a rule, it changes at the end of each season. In order to avoid the need to repair the heat gun on diesel fuel in the part of the power fill, you should regularly take care of the fan. In a dirty condition, it hinders the work process, which increases the load on the generator. Therefore, at least once a season, the fan must be cleaned and cleaned.

Conclusion

In most cases, heat guns are massive structures, which at the same time have an impressive weight. Despite this, such equipment is quite practical in operation and performs its tasks without any problems. True, depending on the design, thermal cannons on diesel fuel may impose special requirements on the place of use. In general, this applies to models with indirect heating, the operation of which is possible only in rooms with organized ventilation. But also do not forget about the specifics of the use of aggregates, directly throwing out combustion products into the environment. Such models are desirable to be used outdoors or in production workshops where the presence of harmful substances will not be dangerous.
