FURNACE WITH AN INCLINED-PUSHING GRATE FOR COMBUSTION OF GRANULATED AND BRIQUETTED FUELS Russian patent published in 2022 - IPC F23B10/00 

FIELD: thermal power engineering.

SUBSTANCE: invention relates to devices for burning granular or briquetted biofuels, as well as granulated or briquetted peat, and can be used in thermal power engineering. Furnace with tilting-pushing grate contains a combustion chamber separated by an arched vault, equipped with fuel supply devices, zonal input of primary air under the second and third zones of the tilting-pushing grate and recirculation gases under the grate and nozzles for feeding recirculation gases into the above-layer volume of the combustion chamber, located on opposite walls above the first zone of the grate with a half-step offset relative to the nozzles of the opposite wall, and nozzles for supplying secondary air located on opposite walls in one inclined plane above the second zone of the grate with a half-step offset relative to the nozzles of the opposite wall, and an afterburning and cooling chamber connected to the combustion chamber by an exit window located in the arched vault at the rear wall of the combustion chamber , and equipped with nozzles for introducing tertiary air, located on opposite walls in the same horizontal plane with a half-step offset relative to the nozzles of the opposite wall, the rear wall of the combustion chamber and its front wall in the zone of the afterburning and cooling chamber and the revolving chamber, as well as the walls of the revolving chamber are closed with gas-tight water-cooled screen panels, and the recirculation gases are introduced under the first zone of the grate, and the arched ceiling of the arched vault is made gas-tight from steel water-cooled pipes connected to collectors.

EFFECT: invention allows to reduce the emission of harmful substances.
