FIELD: heating.
SUBSTANCE: invention relates to the air heaters for the supply air indirect heating in the rooms inlet ventilation and autonomous air heating systems, located in the oil wells immediate vicinity, with the crude oil using as fuel. It contains housing with the air intake inlet, fan, combustion chamber and the recuperative heat exchanger, burner, fuel supply system with the filtration system and the heated air outlet. In front of the fan an air filters system is installed. Fuel filtration system includes dirt collector, self-cleaning coarse and fine filters. Heat-generating installation is made with removable panels, the combustion chamber is equipped with the removable cover, the heat exchanger is equipped with front and rear removable covers.
EFFECT: technical result is the soot formation reduction and possibility of its removal from the unit internal parts, which enables increase in the device operation efficiency with the oil using as fuel.
