In the used combined gas-steam power cycle, figure 1. The topping cycle is a simple Brayton cycle
that has a pressure ratio of 7. Air enters the compressor at 15°C at a rate of 10 kg/s and the gas
turbine at 950°C. The bottoming cycle is an ideal Rankine cycle between the pressure limits of 6
MPa and 10 kPa. Steam is heated in a heat exchanger at a rate of 1.15 kg/s by the exhaust gases
leaving the gas turbine and the exhaust gases leave the heat exchanger at 200°C.
