650 kg/min of superheated steam at 13 Mpa, 582 deg. C enters the turbine and initially expands isentropically to the pressure of 9.2 Mpa. After partial expansion, the steam was reheated with the same pressure at 9.2 Mpa and leaves the first reheater at 520 deg. C. It is once again expanded for the second partial expansion to a pressure of 5.4 Mpa where extraction of steam occurs. The remaining steam was reheated to a pressure of 4.9 Mpa and regained a temperature of 470 deg. C after the addition of heat in the second reheater. The final and complete isentropic expansion was executed until it reached an exhaust pressure of 0.04 Mpa. Draw the corresponding schematic diagram and its T-S diagram. Solve the following -total heat in MW -quality of steam before the condenser. -enthalpy entering the second reheater in KJ/Kg. -rejected heat by the condenser in MW. -net cycle work for the system in kJ/kg. -total reheating for the system in KW -net efficiency for the cycle. -turbine-generated…
