LONG-BURNING EVAPORATION BURNER Russian patent published in 2023 - IPC F23D5/04 F23L7/00 

FIELD: liquid fuel burners.

SUBSTANCE: long-burning evaporative burner device contains a housing, a furnace, a fuel supply tube, a built-in steam generator for superheated steam, consisting of three blocks, namely an evaporator tank in the form of a cylinder with covers on both sides, a steam separator in the form of an annular chamber located at the bottom of the evaporator tank coaxially with it and connected by a steam pipeline, a double blast unit, including a steam superheater in the form of a tube with hollow walls, a holder for two steam nozzles connected to the superheater by a branch pipe and a prechamber installed coaxially with the nozzle holder and the superheater, and the double blast unit itself is mounted in the side walls of the steam separator in a horizontal position. The device contains two cup-shaped covers installed on both end sides of the steam separator, where the lower cover functions as a furnace, and the upper cover functions as a thermal resistance, and also contains air supply pipes mounted in the side walls of the steam separator in the plane of the axis of the steam nozzles, in addition, it contains a thermal electric heater installed between the evaporator tank and the steam separator to start the device and a fuel supply tube is mounted obliquely into the side walls of the steam separator.

EFFECT: invention makes it possible to increase the thermal power of the device without increasing its dimensions.
