The presure ratio in a gas power plant is

WebbThus, even though the efficiency (which is not much dependent on the firing temperature) would peak at pressure ratios of about 30 : 1, typical simple-cycle gas-turbine power plants have pressure ratios of between 10 : 1 and 18 : 1, thus optimizing the power out. WebbThe gas turbine part of a combined gas-steam power plant has a pressure ratio of 16. Air enters the compressor at 300 K at a rate of 14 kg/s and is heated to 1500 K in the combustor. The combustion gases leaving the gas turbine flow thru a HRSG heat exchanger to heat the steam to 400 C at 10 MPa. The combustion gas leaves the HRSG …
