A system for providing a demand signal to control the boiler inputs in a boiler-turbine combination operating in a sliding pressure mode with the generation being controlled to a desired value. The demand signal for the boiler inputs is obtained by multiplying the ratio of first stage turbine pressure to throttle pressure by the throttle pressure set point and the throttle pressure set point is controlled so as to maintain the first stage temperature at a preset desired value. The demand signal is modified to trim the boiler inputs to maintain the throttle pressure at its set point. |
