EXTERNALLY FIRED COMBINED CYCLE GAS TURBINE SYSTEM

摘要

A gas turbine system of the type haying a compressor fox compressing ambient air and producing compressed air, a heater for heating the compressed air to produce heated gas, a turbine for expanding the heated gas to produce. expanded gas, and an electric generator connected to the turbine for generating electricity that is supplied to a load, said system comprising: a) a source of energy including solar energy, oil shale, solid waste fuel, land fill gas, biomass, or combinations thereof, and/or solid, liquid, or gaseous hydrocarbon fuels, for heating said compressed air in the heater and producing heated gases; and b) a closed Rankine cycle power plant having a heat exchanger for vaporizing working fluid and producing working fluid vapor using heat contained in said heated gas, a vapor turbine for expanding the working fluid and producing power for the load, and expanded working fluid vapor, a working fluid condenser for condensing the expanded working fluid vapor and producing working fluid condensate, and means for returning said working fluid condensate to said heat exchanger.
