    摘要： Maintenance operations for a hot gas path of a gas turbine require shutdown and cooled down conditions. When a gas turbine is shut down, thermal gradients in the rotor cause stresses that limit the life of the major components. As the cooling rate is increased to reduce the time, the stresses are increased, reducing rotor life. A method and equipment are provided to reduce the overall cycle time for the maintenance, yet mitigate the life penalties, thereby providing greater power production while maintaining (or potentially extending) rotor life. The method includes small hold times during the turbine shutdown and startup and slower turbine ramp rates during cooldown and startup, which more than offset thermal stresses from a forced cooldown, considerably shortening the overall operation.

    摘要： A system for operating a combustor includes a sensor that measures an operating parameter associated with the combustor and generates a signal reflective of the operating parameter. The operating parameter is reflective of an ash deposition rate or an accumulated ash buildup. A controller receives the signal, compares the signal to a predetermined limit, and generates a control signal. A method for operating a combustor includes operating the combustor at a first power level that produces a first temperature that is less than or equal to a first predetermined temperature and creating a layer of ash. The method further includes measuring an operating parameter reflective of an ash deposition rate or an accumulated ash buildup, comparing the operating parameter to a limit, and operating the combustor at a second power level that produces a second temperature that is greater than or equal to the first predetermined temperature.
