ABSTRACT:
A cogeneration plant is disclosed in which the feedwater from the deaerator heater is placed in heat exchange relation with the makeup water before the makeup water is delivered to the deaerator heater. The amount of heat transferred from the feedwater to the makeup water is controlled in response to the stack gas temperature. The feedwater from the heat exchanger is then placed in heat exchange relation with the stack gas, either in the economizer or through a separate coil, to take advantage of waste heat that would otherwise be lost.
