In combined cycle, the highest plant efficiency does not require the highest gas turbine efficiency or pressure ratio. A balance has to be struck between the gas turbine firing (combustion) temperature and pressure ratio to maximize the steam cycle output. In such circumstances, inlet air warming using scavenged heat can improve CCGT efficiency ...
