Consider a regenerative vapor power cycle with a single open feedwater heater. Steam enters the first turbine stage at 12MPa, 500 0C, and expands to 0.3MPa where some steam is extracted and fed to the feedwater heater. The remainder expands through the second-stage turbine and exits at the condenser pressure of 0.01 MPa. Saturated liquid at 0.3 MPa leaves the open feedwater heater.

Steam is extracted at 2.0 MPa for CFWH and the remainder for reheating. The reheated steam enters the 2nd stage turbine at 1.5MPa and expands to 1.0 MPa where more steam is extracted for OFWH.
