Abstract:
A gas turbine system comprising:a gas turbine including a first compressor for compressing air, defining a first source of compressed air, a combustor in flow communication with said compressor for receiving a first portion of the air compressed by said first compressor, and a combustion turbine for expanding a hot working gas flowing thereto from said combustor;a second source of compressed air;an extraction air flow path for a second portion of said air compressed by said first compressor;an auxiliary air flow path for compressed air from said second source of compressed air;a pressurized fluidized bed combustor (PFBC) operatively coupled to at least one of said extraction air flow path and said auxiliary air flow path, for receiving compressed air therefrom for burning a solid fuel to produce hot gas;an expander turbine; anda hot gas flow path for conducting said hot gas from said PFBC to said expander turbine for generating power from said hot gas.
