Closed feedwater heater temperatures
WebSome steam is extracted from the turbine at 1 Mpaa and is completely condensed in the closed feedwater heater and pumped to 8 Mpaa before it mixes with the feedwater heater at the same pressure in a mixing chamber. The Terminal Difference for the CFWH, (i.e., the difference between the temperatures of the fluids leaving the heater) is 5 deg C ...
