System and methods for heat recovery steam generators hot purging

A control system (100) for use in operating an energy system includes calculating an auto-ignition temperature (202) of a fuel in use with the energy system, storing the auto-ignition temperature in a system memory, unloading a gas turbine (102) associated with the energy system to a pre-determined...

Zusammenfassung:	A control system (100) for use in operating an energy system includes calculating an auto-ignition temperature (202) of a fuel in use with the energy system, storing the auto-ignition temperature in a system memory, unloading a gas turbine (102) 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 (104) 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.
