【Abstract】 The advantages of the gas turbine and the gas turbine combined cycle (GTCC) generation technology were introduced and the fundamental thermodynamics principle of retrofitting the current coal-fired power plant applying gas-steam combined cycle with non supplementary fired HRSG was analyzed. The generation efficiency and economics of the coal-fired power plant retrofitted with gas-steam combined cycle with traditional non supplementary fired HRSG were analyzed and calculated and the technical and economic feasibility of such a retrofit were verified.更多还原
