OPTIMIZATION OF HYDROGEN FUELED GAS-TURBINE STEAM-TURBINE COMBINED CYCLE

The optimum cycle of hydrogen fueled gas turbine-steam turbine combined cycle has been determined by the multiplier method. In order to apply the multiplier method to this cycle, the thermodynamic properties of steam such as enthalpy and entropy should be expressed as functions of temperature and pressure. In the present study, they are approximated by polynomial functions. These procedures, therefore, can be applied to the combined cycle successfully and optimum working conditions of the combined cycle have been made clear.
