Assuming a 20 MW simple cycle gas turbine with a firing temperature of 1600K develop an analysis of a combined cycle. Assume that Tmax in the Rankine cycle is 560 C Pmax = 60 Bar and Pmin = 0.08 Bar. Assume an air inlet temperature of 300 K and use realistic component efficiencies. (?t = 0.88 ?c = 0.86 and ?st = 0.89). You may use interactive thermodynamics on this assignment but do a hand calculation on the waste heat recovery steam generator. You may use an open feedwater heater if you want but not a reheat. Determine the overall cycle efficiency.
