  • Method of operating a gas turbine power plant with auxiliary power to reduce emissions
    Patent number: 8495858
    Abstract: A method of operating a gas turbine power plant including an auxiliary power output for reducing power plant emissions. A heat recovery steam generator receives an expanded working medium from a gas turbine and removes heat from the expanded working medium to form a reduced temperature exhaust gas and to generate steam from the heat removed from the expanded working medium. A steam turbine and generator assembly operates on the steam to produce an auxiliary plant output. A selective catalytic reduction (SCR) system is provided for receiving the reduced temperature exhaust gas; and an auxiliary fan is powered by the auxiliary plant output to supply dilution air for further reducing the temperature of the exhaust gas to prior to passing the exhaust gas through the SCR system.
