Abstract:
1. A combined cycle power plant for producing electrical power comprising: A gas turbine engine with a compressor, a combustor and a turbine, the gas turbine engine burning a first fuel; a first electric generator rotatably connected to the gas turbine engine; a heat recovery steam generator with an inlet connected to an outlet of the turbine; a steam turbine connected to receive steam from the heat recovery steam generator; a second electric generator rotatably connected to the steam turbine; a second combustor for burning a second fuel to produce a hot gas stream; a bypass passage to connect the turbine outlet to an inlet of the second combustor; a hot gas stream passage to connect an outlet of the second combustor to the inlet of the heat recovery steam generator; and, some of a turbine exhaust is passed directly into the heat recovery steam generator while a remaining turbine exhaust is passed into the second combustor to produce the hot gas stream that is then mixed with the turbine exhaust to produce steam for the steam turbine.
