ABSTRACT:
A portion of solid fuel is pyrolyzed in a pyrolyzer to produce combustible gases and carbonaceous material, the carbonaceous material being supplied from the pyrolyzer to a furnace. A further portion of the solid fuel is added to a furnace and is combusted with the carbonaceous material therein to produce combustion products that include hot flue gases and ash particulate. The combustion products are separated into a plurality of streams, one of which contains coarse ash and another of which contains flue gases and fine ash. A portion of the coarse ash is directed into the pyrolyzer while a further portion is disposed of, preferably by being used to heat air entering the furnace.
