BURNER OF SOLID FUEL BOILER AND METHOD OF USE THEREOF Russian patent published in 2021 - IPC F23K3/14 F23B40/04 

FIELD: physics.

SUBSTANCE: invention relates to the field of power engineering. Burner of solid fuel boiler installed vertically in furnace is made in form of inverted truncated cone of retort with holes for air supply. Cone is connected by narrow side with fuel supply device equipped with auger conveyor, and wide side - with shell of distributing element of air supply. Supply pipes of fuel and air supply are made from one pipe with inner sealed plug symmetrically relative to vertical axis of burner. On the intersection of longitudinal axis of fuel supply auger and vertical axis of truncated cone of retort there is backward connection of auger stripe of forward supply and reverse feed. In truncated cone of retort in holes for air supply, from lower row along circumference and upwards along rows, diameter is reduced in proportion with height between rows.

EFFECT: technical result is creation of solid-fuel boiler burner with rational arrangement of structure, with increased reliable and efficient operation.
