RECUPERATIVE BURNER Russian patent published in 2017 - IPC F23D14/66 

FIELD: heating system.

SUBSTANCE: recuperative burner comprises a casing enclosed in a casing to form a smoke channel with a twist generator and a tangential air supply pipe installed in a casing with an annular clearance, a combustion chamber with gas nozzles in the inlet section and equipped with an exit nozzle and a swirler. The case of the recuperative burner is made in the form of a truncated cone tapering towards the exit nozzle.

EFFECT: intensification of heat transfer in the most thermally stressed sections of the combustion chamber and the burner housing near its outlet nozzle will allow the effective cooling by a swirling air flow, reducing the maximum temperatures and increase the operational reliability of the recuperative burner.
