DATA INTEGRATION METHOD FOR ECONOMIC EVALUATION OF WATERSPRAY COOLING INLET AIR IN A GAS AND STEAM TURBINE COMBINED CYCLE

To cool the inlet air is a simple and effective measure for improving the inlet air temperature behavior of gas turbine combined cycle(GTCC).For accurately analysing the economic behavior of inlet air cooling technology,important data have been provided,the inlet air temperature behavior of GTCC facility being simulated in this paper,and practical fitting formula being given.Combining three variables,namely the inlet air temperature behavior,the regularity of unit's load variation,and the local meteorologic parameter,an economic analysis method for waterspray cooling inlet air has been given on the basis of data integration.
