RECUPERATIVE BURNER BLOCK Russian patent published in 2021 - IPC F23L15/04 

FIELD: energy.

SUBSTANCE: invention relates to the field of energy. The recuperative-burner block contains a burner and a recuperator with an air supply unit, which includes a flow swirl generator with a tangential air supply pipe, forward and reverse annular air ducts connected through a swirler, serially connected to the flow swirl generator and separated by a partition, while the return duct is connected to to the air manifold connected to the burner, a cylindrical heat-transferring wall, a smoke channel with radiation and convective stages, the latter containing a perforated pipe plugged from the rear end. The inlet part of the perforated pipe is made in the form of an inner quarter of a torus, on the outer surface of which there are protrusions, and on the inner surface of the cylindrical heat-transferring wall there is an annular flow divider.

EFFECT: invention makes it possible to increase the final temperature of the heated air and to increase the thermal efficiency of the proposed device.
