Patent ID: 8104283

Claim:
A method of controlling a steam generating boiler system having a furnace, a superheater section and a reheater section, comprising: obtaining, at a controller, a first signal, the first signal being indicative of a desired value of: a reheater control variable, or a reheater manipulated variable, and the first signal being not indicative of a superheater spray setpoint; obtaining, at the controller, a second signal indicative of an actual value of: the reheater control variable, or the reheater manipulated variable; using the first signal in conjunction with the second signal to generate, by the controller, a third signal; and using the third signal in conjunction with a signal indicative of a firing rate to generate, by the controller, a fourth signal to control: a fuel feedwater ratio of the furnace and a boiler of the steam generating boiler system, a fuel/air mixture provided to the furnace, or an amount, a quanity or a type of fuel, to thereby control a steam temperature generated by the superheater section.
