The second steam power plant operates on a regenerative Rankine cycle, where water is used as the working fluid. Steam enters the turbine at 8 MPa and 450 ºC. After isentropic expansion in the first stage of the turbine, steam is extracted at an intermediate pressure of 0.75 MPa and passed to a closed feedwater heater. The feedwater leaves the heater at 8 MPa and a temperature equal to the saturation temperature at 0.75 MPa.

Consider a reheat-regenerative vapor power cycle with two feedwater heaters, a closed feedwater heater and an open feedwater heater. Steam enters the first turbine at 8000 kPa and 480oC and expands to 700 kPa. The steam is reheated to 440oC before entering the second turbine, where it expands to the condenser pressure of 8 kPa. Steam is extracted from the first turbine at 2000 kPa and fed to the closed feedwater heater. The feedwater leaves the closed heater at 205oC and 8000 kPa and enters the boiler to complete the cycle. The condensate from the closed feedwater heater is throttled into the open feedwater heater. Steam extracted from the second turbine at 300 kPa is also fed into the open feedwater heater, which operates at 300 kPa. The stream exiting the open feedwater heater is saturated liquid at 300 kPa.
