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. Gas turbine power plants are lighter and compact when compared to power plants running on vapour cycles. The power to weight ratios are generally high for high throughout Gas turbine power plants and hence are favoured for the aviation and also for power generation. A simple GT power plant is shown in the … Visa mer Internal combustion engines: Combustion of fuel is non-cyclic process.
