An 850-MW Rankine cycle operates with turbine inlet steam at 1200 psia and 1000°F and condenser pressure at 1 psia. There are three feedwater heaters placed optimally as follows: (a) the high-pressure heater is of the closed type with drains cascaded backward; (b) the intermediate-pressure heater is of the open type; (c) the low- pressure heater is of the closed type with drains pumped forward. Each of the turbine sections has the same polytropic efficiency of 90 percent. The pumps...

A power plant operates on a regenerative vapor power cycle with one open feedwater heater. Steam enters the first turbine stage at 12 MPa, 560°C and expands to 1 MPa, where some of the steam is extracted and diverted to the open feedwater heater operating at 1 MPa. The remaining steam expands through the second turbine stage to the condenser pressure of 17 kPa. Saturated liquid exits the open feedwater heater at 1 MPa. The net power output for the...
