  • Method and system for reducing power plant emissions
    Patent number: 8104259
    Abstract: A method for operating a power plant to facilitate reducing emissions, wherein the power plant includes a gas turbine engine assembly and a carbon dioxide (CO2) separator. The method includes increasing an operating pressure of exhaust gas discharged from the gas turbine engine assembly, separating substantially all the CO2 entrained within the gas turbine engine utilizing the CO2separator to produce a CO2 lean airstream, reducing the operating temperature of the CO2lean airstream, and utilizing the cooled CO2lean airstream to facilitate reducing an operating temperature of air entering the gas turbine engine assembly.
    Type: Grant
    Filed: April 8, 2011
    Date of Patent: January 31, 2012
    Assignee: General Electric Company
    Inventors: Narendra Digamber Joshi, Lautaro Aspiazu Montgomery, James William Stegmaier

  • Methods for operating gas turbine engines
    Patent number: 6935119
    Abstract: A method for operating a gas turbine engine including a high pressure compressor, a variable inlet guide vane assembly and a water injection apparatus for injecting water into a flow of the engine is provided. The method comprises transmitting engine operating parameters including a temperature of the gas flow at an outlet of the high pressure compressor, T3, to an engine controller, using the controller to regulate a flow of water injected into the gas flow and to adjust a relative position of the inlet guide vane assembly until engine full power is about reached as determined by a pre-defined T3 operating parameter limit, and adjusting the controller to then facilitate operation of the engine with an increased output without exceeding the pre-defined T3 operating parameter limit.
