In a steam power plant operating on the ideal regenerative Rankine cycle with one open feed water heater, steam enters the turbine at 9 MPa, 480oC and is condensed in the condenser at a pressure of 7 kPa. Bleeding from the turbine to the FWH occurs at 0.7 MPa. The net power output (W⋅ net) of the cycle is 100 MW. The boiler receives heat from a source at 1200oC and the condenser rejects heat to atmosphere at 100 kPa, 25oC.
(a) Perform an energy inventory and draw an energy flow diagram for the cycle. Determine (b) The thermal efficiency (ηth) and
(c) Energetic efficiency of the cycle.
