Patent ·
OSTI ID:6493923
This patent describes a method for heat rate improvement. It is used in a steam turbine thermal cycle employing a steam-to-steam reheating system having a high pressure moisture-separator-reheater (MSR) with a reheater drain for fluid, feedwater heaters connected in series to heat feedwater at increasing pressure, each of the feedwater heaters having an inlet, an outlet for feedwater, and a heat exchanger connecting in heat exchange relationship with feedwater exiting the highest pressure feedwater heater. The system utilizes scavenging steam to prevent moisture buildup.
