    摘要: A system that controls temperature in a heat recovery steam generator (HRSG). One heat recovery steam generator system may include a first exhaust path. The heat recovery steam generator system also may include a second exhaust path. The heat recovery steam generator system may include a first damper configured to selectively allow a portion of an exhaust to flow through the second exhaust path.

    摘要: A technique of controlling a boiler system such as that used in a power generation plant includes using manipulated variables associated with or control inputs to a reheater section of the boiler system to control the operation of the furnace, and in particular to control the fuel/air mixture provided to the furnace or the fuel to feedwater ratio used in the furnace or boiler. In the case of a once-through boiler type of boiler system, using the burner tilt position, damper position or reheater spray amount to control the fuel/air mixture or the fuel to feedwater flow ratio of the system provides better unit operational efficiency.
