FIELD: heating.
SUBSTANCE: invention used for heat generation, light, power during burning fuel in radiation recuperative burner. The radiation recuperative burner consists of a case, inside of each a burner tunnel located, a countercurrent recuperator, which has at least one combustion product tunnel and at least one oxidant tunnel, burner tunnels fuel injection unit, connected to external pipeline for fuel supply, burner tunnels oxidant injection unit, connected to external pipeline for oxidant supply and combustion product discharge unit, connected to external pipeline for combustion product withdrawal, a lighter, at that part of the burner case in which burner tunnel located, made of fireproof and refractory materials, oxidant recuperator's tunnels have a thermal contact surface with combustion products tunnels, by opposite side of which gas flow direction is reversal, the oxidant tunnel exit connected to the burner tunnel, the combustion products tunnel entrance connected to the burner tunnel, the fuel injection unit hermetically connected to the burner tunnel, the oxidant injection unit hermetically connected to the recuperator's oxidant tunnel entrance, the combustion products discharge unit hermetically connected to recuperator's combustion products tunnel exit. The burner tunnel inside the case is sealed and isolated from outside environment, in the recuperator additionally created one or few fuel tunnels, which have thermal contact surfaces with the recuperator's combustion products tunnels, by opposite side of which gas flow direction is reversal, at the recuperator located inside of the burner case, its tunnels walls, which adjusted to the burner tunnel, made of fireproof and refractory materials, the fuel injection unit hermetically connected to the burner tunnels via recuperator's fuel tunnels, and part of the case external surface neighboring to the burner tunnel presents the burner radiation surface.
EFFECT: invention allows to create device, which can perform fuel total combustion and heat exchange at temperatures higher than 2000°C.
