Feedwater Heater

The high pressure feedwater heater is a counter flow, shell and tube heat exchanger that raises the temperature of the feedwater before entering the steam generator. By raising the feedwater temperature, the steam generator is more efficiently sized for its task of converting feedwater to steam and the plant operates at a higher efficiency. Steam is drawn from an extraction point on the turbine and the condensed drains cascade to the deaerator and join into the feedwater stream.
