Water is the working fluid in an ideal regenerative Rankine cycle with one closed feedwater heater. Steam enters the turbine at 1400 lbf/in.2 and 1200°F and expands to 120 lbf/in.2, where some of the steam is extracted and diverted to the closed feedwater heater. The remaining steam expands through the second-stage turbine to the condenser pressure of 2 lbp/in.2 Condensate exiting the feedwater heater as saturated liquid at 120 lbf/in.? undergoes a throttling process as it passes through a trap into the condenser. The feedwater leaves the heater at 1400 lbf/in.? and a temperature equal to the saturation temperature at 120 lbf/in.? The net power output of the cycle is 283 MW.
