초록

A gas turbine system in which substantially all of the compressed air from the compressor portion of the gas turbine is used to fluidize a bed of solid fuel, such as char, in a pressurized fluidized bed gasifier so as to produce a hot gas. The hot gas flows through a heat recovery steam generator so as to produce steam, which is expanded in a steam turbine so as to produce shaft power. A first portion of the hot gas from the heat recovery steam generator is expanded in the turbine section of the gas turbine so as to produce additional shaft power. A seco...
