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