摘要: A control system for a heat exchanger, such as superheater in fossil fuel fired steam generator, uses multivariable non-linear regression equation to develop feed forward signal that continuously adapts itself changes variables adjust the enthalpy of entering and maintain substantially constant discharged from superheater. The develops feedback responsive temperature readjust required leaving at predetermined set point temperature.
