摘要： A temperature control system for a superheater of a drum or separator type fossil fuel fired steam generator develops a feed forward signal (F 2c ) that continuously adapts itself to changes in system variables to adjust the enthalpy (h₃) of the steam entering the superheater to change the heat absorption therein in accordance with changes in system variables to thereby maintain a substantially constant enthalpy (h₄) of the steam discharged from the superheater. The system develops (27,31) a feedback signal responsive to changes in the temperature (T₄) of the steam discharged from the superheater (1) to readjust the enthalpy (h₃) of the steam entering the superheater as required to maintain the temperature (T₄) of the steam discharged from the superheater at a predetermined set point value (29).
