HEATER AND EVAPORATOR BURNER Russian patent published in 2022 - IPC B60H1/03 F23D3/40 

FIELD: energy.

SUBSTANCE: invention relates to the field of energy. A heater with a cup-shaped heat exchanger and an evaporative type burner is proposed, including a combustion chamber with a cylindrical wall and a transverse wall with a through outlet to stabilize the flame, and a coaxial flame tube inserted into the heat exchanger with a gap to remove combustion products from the outlet of the flame tube along the inner surface of the heat exchanger and the outer surface of the flame tube welded to the transverse wall of the combustion chamber, while on the outer side of the flame tube and the transverse wall of the combustion chamber an annular ledge is formed and the outer side of the transverse wall of the combustion chamber is located across the flow of the discharged combustion products in the gap between the wall of the heat exchanger and the flame tube.

EFFECT: invention makes it possible to reduce the heating temperature of the transverse wall with a through outlet and increase the reliability of the burner and heater.
