SOLID FUEL BOILER BURNER Russian patent published in 2019 - IPC F23B30/04 

FIELD: power engineering.

SUBSTANCE: solid fuel burner has combustion chamber (1) with air supply holes, driven by an electric motor, transmitted through the transmission, and an auger fuel feeder with an electric motor driving auger screw feeder (9), as well as elements of fuel supply channel (8) with an outlet in the near region of auger fuel supply device (9), for supplying fuel to combustion chamber (1), and air injection elements that supply air to the area below and/or above the fuel combustion layer, rotary combustion chamber (1), located in housing (2), is equipped with channels of primary and secondary air, and housing (2) is connected by hook clips with gear (6), mounted for rotation between two bearing cages installed between the main plate and a pressure plate with holes for supplying air from air discharge chamber (24), an adjustable gate valve, which, when increasing or decreasing the clearance of the holes, controls the ratio of secondary and primary air supplied to the channels of the primary and secondary air; auger fuel supply device (9) has an air supply channel located along the axis, the openings of which are openings located in the zone of air injection chamber (24) and the outgoing openings are openings in combustion chamber (1).

EFFECT: invention makes it possible to improve the quality of fuel combustion; it is quickly easy to separate the combustion chamber from the burner body.
