A combined cycle power plant to generate a net power output of 550 MW. The maximum temperature of the Brayton cycle is 1150 K. Air intake condition is 100 kPa and 30°C. Condenser pressure of the Rankine cycle is 45 kPa. Boiler (heat exchanger) pressure of the Rankine cycle is 10 MPa. The isentropic efficiency of the gas turbine is 0.87 and that of the compressor is 0.85. Isentropic efficiency of the feedwater pump is 0.8, and that of the steam turbine is 0.81. Use constant specific heats for air at the inlet temperature to each component. Use EES to:1- design the cycle (basic design = a cycle that does not violate any laws2 - run optimization trials to reach a maximum overall thermal efficiency3 - run performance trials to show the effect of Brayton pressure ratio on the thermal efficiency while keeping the basic design for the Rankine cycle4 - Add second law analysis to your EES code and generate data for irreversibility and 2nd - law efficiency of each of the components of both cycles
