ABSTRACT:
Combustible gases are produced from a solid fuel by pyrolizing the fuel in a pyrolyzer containing a low grade solid fuel producing combustible gases, and carbonaceous material that is combusted in a furnace to produce hot products that include hot flue gases and particulate material. The hot products are separated into a plurality of streams, one of which contains comparatively coarse ash which is directed into the pyrolyzer for effecting the pyrolyzation of the fuel. A stream of reaction gases is applied to the pyrolyzer in such a way that the stream of reaction gases bubbles through the carbonaceous material in the pyrolyzer without fluidizing such material. In effect, the reaction gases activate the void fraction in the pyrolyzer thereby reducing the residence time of the material therein. In one embodiment of the invention, the combustible gas produced by the pyrolyzer is burned in a combustion chamber of a boiler that produces boiler flue gases which constitute the reaction gases applied to the pyrolyzer. In a further embodiment, the combustible products produced by the furnace are separated into a stream containing flue gases and ash. At least a part of the latter stream may constitute the reaction gases applied to the pyrolyzer.
