摘要
A method for operating a power plant may include, during shutdown of a turbine, controlling a damper to move from a first position directing turbine exhaust to enter a heat recovery system to a second position to allow the turbine exhaust to enter a bypass stack and block the turbine exhaust to the heat recovery system. While the position of the damper is maintained in the second position, fired shutdown of the turbine may be performed. In response to instructions to start the turbine, air flow in an exhaust duct for a predetermined period of time is generated, and after generating the air flow for the predetermined period of time, the turbine may be started without performing a purge sequence for the heat recovery system. After starting the turbine, the damper may be controlled between the second position and the first position.
