Abstract
A superheater spray water control system for variable pressure applications produces an output signal representative of expected superheater absorption as a function of measured steam flow, compensates the signal for temperature variations within the superheater and adjusts it for over/under fire transients. An output signal representative of required superheater absorption from the drum to the superheater outlet, together with a spray water enthalpy signal obtained as a function of measured stem flow, is used with the compensated and adjusted actual superheater absorption and measured steam flow signals to produce a spray quantity demand signal.
