Effective Parameters on Performance of Multipressure Combined Cycle Power Plants

A parametric analysis is performed for numerous configurations of a combined-cycle gas turbine (CCGT) power plant, including single-pressure, double-pressure, triple-pressure, triple-pressure with reheat, and supplementary triple-pressure with reheat. The compression ratio of the gas turbine and the...
