In accordance with the present invention, a method for supplying solid material such as hot carbonaceous material from a pyrolyzer or reactor to a furnace, is provided comprising providing a screw conveyor for receiving the solid carbonaceous material from the pyrolyzer or reactor preferably from above the conveyor and transporting it along its length to a vaned rotor preferably positioned on the axle of the screw conveyor preferably substantially near the end of the screw conveyor for supplying the carbonaceous material to the furnace.

Method of and means for producing combustible gases from low grade fuel

Combustible gases from pulverized solid fuel are generated by semi-coking the pulverized solid fuel in a reactor in the absence of oxygen to produce a solids stream that includes carbonaceous material and a gas stream that includes hydrocarbon gases and tar fumes. The carbonaceous material in the solids stream is gasified in a fluidized bed using steam and hot air to produce an output stream that includes combustible gases and coke particles. The output stream is combined with the gas stream to form a combined stream which is separated into a combustible gas stream and a hot particulate stream. At least a part of the hot particulate stream is applied to the reactor.

Method of and apparatus for producing combustible gases from pulverized solid fuel

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.
