<P>PROBLEM TO BE SOLVED: To provide an apparatus and method for controlling oxygen emissions from a gas turbine. <P>SOLUTION: A combined cycle power plant 10 includes a first compressor 16 for producing a compressed working fluid 22, and a turbine 20 downstream of the first compressor 16. The turbine 20 includes stationary components and rotating components and produces exhaust gases 38. A heat exchanger 32 downstream of the turbine 20 receives the exhaust gases 38 from the turbine 20, and a second compressor 48 downstream of the heat exchanger 32 receives the exhaust gases 38 from the heat exchanger 32 and provides a flow of the exhaust gases 38 to the turbine 20. A method for reducing oxygen emissions from a gas turbine 12 includes a step of flowing the exhaust gases 38 from the turbine 20 to the heat exchanger 32 and removing heat from the exhaust gases 38, and a step of increasing the pressure of the exhaust gases 38 to produce a pressurized exhaust gas and flowing the pressurized exhaust gas back to the turbine 20 to remove heat from the turbine 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
