FIELD: heating.
SUBSTANCE: device for gas heating comprises a cylindrical body equipped with a nozzle of air supply. Inside the body there is a perforated cylinder installed coaxially, in the cavity of which there is a cylindrical body coaxially installed in the chamber of gas heating. The cavity between the perforated cylinder, the cylindrical body of the gas heating chamber and the circular chamber of fuel supply with an inlet fuel nozzle, installed at the end of the perforated cylinder, forms a combustion chamber. In the cavity of the gas heating chamber body there is a coaxially perforated cylinder for supply of cold gases with an inlet nozzle of cold gases, installed coaxially. The gas heating chamber is equipped with a nozzle for discharge of hot gases.
EFFECT: provision of effective heating of various gases, including combustible ones, and air with exclusion of direct contact of heated gases with spent smoke gases and their subsequent mixing.
