Abstract
An improved configuration for dual fluid steam injected power generators incorporates means to bypass the steam generated by the heat recovery steam generator (HRSG) around the superheater. The bypass allows for variation in the amount of superheat added to the injection steam used by the gas turbine. In an alternative configuration, the bypass means is placed between the turbine gas outlet and the superheater gas inlet. The bypass allows the hot turbine exhaust gases to be switched between the HRSG gas inlet and the superheater gas inlet. Finally, a method for controlling the power output and amount of steam generated by a steam injected power generator is described.
