Abstract:
A dual fluid cycle power/steam generator including a compressor, a combustion chamber, a gas turbine driven by combustion gases and steam from the combustion chamber and from which exhaust gas exits, a steam injection system for injecting steam within the combustion chamber, and wherein the steam injection system comprises:a superheater for injecting super heated steam, heated therein by the exhaust gases and steam which exits from the gas turbine, within the combustion chamber and wherein lower energy exhaust gases exit from the superheater;heat recovery means for using the lower energy exhaust gases from the superheater, to heat water into lower temperature process steam, and to provide lower temperature steam to the superheater; andalternate means for regulating the amount of heating of the low temperature steam by the superheater in a range from a minimum of no heating to a maximum amount of heating.
