FIELD: combustion apparatus.
SUBSTANCE: invention relates to power engineering. Dark type radiator with burner (1), fan (3) and radiating pipe (4), wherein burner (1) is connected to the combustible gas supply, and the suction side fan (3) is connected to ejector (32), in which the inlet branch pipe is connected to the waste gas discharge channel, wherein the combustion air sucked by fan (3) serves as a working medium, so that fan (3) supplies to burner (1) a mixture of exhaust gas and combustion air, wherein burner (1) serves to supply flame (6) to radiant tube (4), combustible gas supply (2) is connected to a hydrogen source serving as a source of combustible gas, is equipped with gas nozzle (21), at a distance from gas nozzle (21) there is ignition device (11).
EFFECT: invention makes it possible to reduce risks of flame back impact to the nozzle, to reduce emission of harmful substances.
