FIELD: power industry.
SUBSTANCE: method of solid fuel combustion involves fuel combustion on a grate, air supply to combustion zone via a duct above the grate, air exhaust through the grate slot to a duct, small fuel and slag fraction filtering in the duct, further removal of combustion remainders from the grate and duct by duct wall opening and grate slop cleaning. Small fuel fractions are removed before burning, dried during burning and fed to a next grate with smaller slot, positioned below the first grate.
EFFECT: higher fuel combustion grade, simplified furnace design, enhanced furnace efficiency.
