A regenerative vapor power cycle has three turbine stages with steam entering the first stage at 2500 lbf/in2 , 1000oF. The cycle has two feedwater heaters, a closed feedwater heater using extracted steam at 600lbf/in2 and an open feedwater heater operating at 60 lbf/in2 . Saturated liquid condensate drains from the closed feedwater heater at 600 lbf/in2 and passes through a trap into the open heater. The feedwater leaves the closed has .
