  • System and methods for heat recovery steam generators hot purging
    Patent number: 7861532
    Abstract: A method for operating an energy system includes calculating an auto-ignition temperature of a fuel in use with the energy system, storing the auto-ignition temperature in a system memory, unloading a gas turbine associated with the energy system to a pre-determined range of operations, controlling a temperature of the exhaust flow discharged from the gas turbine, opening an exhaust bypass damper to a pre-determined position to enable a pre-determined volume of air to enter an exhaust flow path defined within the energy system, and releasing the energy system for normal operation after a pre-determined amount of time has elapsed.
    Type: Grant
