FIELD: heating equipment.
SUBSTANCE: invention relates to heat engineering and can be used in boiler plants. Method for burning solid fuel includes feeding into the upper part of the furnace a solid lump fuel, removing solid combustion products from the bottom of the furnace, the supply of oxidizer to the furnace through the grate, the transfer of heat from the combustion of a heat exchange system with heat exchangers with a heat transfer fluid, and the removal of flue gases. Grate is made of vertical pipes with a coolant located in the center of the furnace, the supply of a gas oxidant is carried out along a vertical pipe inside the grate, the output of the combustion products is carried out through the side walls of the furnace, made of a refractory material with passage channels of gases.
EFFECT: increase of reliability and durability, increase of energy efficiency, expansion of used types of fuel, including low-energy ones.
