A comparative study of the influence of different means of cooling on the thermodynamic efficiency and specific power of combined (gas and steam turbines) cycle is presented. The study extends the previously developed methodology evaluating the influence of cooling and coolant requirements on gas turbine performance. In this study, the exhaust gases of the gas turbine are used as the heat source to a steam cycle using single reheat with a specified temperature difference at the pinch point. The sensitivity of the overall cycle efficiency to each key input parameter is reported.
