Abstract:
A power plant comprising:a) a gas turbine unit having a compressor for compressing ambient air, a burner for heating air compressed by said compressor, a generator, and a turbine coupled to the compressor and to said generator for expanding air heated by said burner to drive said compressor and generator such that the turbine produces hot exhaust gases and the generator produces electricity; b) means for supplying fuel to said burner; c) a combustor for containing particles of solid fuel; d) means applying said exhaust gases to said combustor for fluidizing and combusting said particles in said combustor to produce hot products of combustion that include coarse ash particulate; e) a separator for separating ash particulate from said products of combustion and producing separated products of combustion; f) a waste heat boiler, separate from said combustor, responsive to said separated products of combustion for producing steam; g) means for supplying solid fuel to said combustor; h) a steam turbine for expanding said steam and producing power; i) a steam condenser unit for condensing steam expanded in said steam turbine; j) means for returning the condensate produced by said condenser unit to said waste heat boiler; and k) a pyrolyzer adapted to contain crushed oil shale for receiving ash extracted by said separator and producing a carbonaceous residue that is supplied to said combustor.
