HMK-4: Combined cycle A combined power plant consisting of a closed gas turbine unit using air and a steam turbine cycle such that the heat rejected from the air is used to produce steam in a steam generator. The air leaving the steam generator at 200°C and is cooled to the compressor inlet temperature by a separate cooler which rejects heat to waste. The properties of the working fluid for each cycle are tabulated below. Assume ideal operation for both cycles and calculate: a. Steam mass flow per unit mass of air. b. Total power output per unit mass of air. c. Thermal efficiency of the combined cycle. Pressure ( bar) Air cycle | Steam cycle | Steam Condenser generator Pump
