Paper Details

A steam power plant operating on a regenerative cycle, as illustrated in Fig. 8,5, includes just one feed water healer. Steam enters the turbine at 650(psia) and 900(oF) and exhausts at 1(psia). Steam for the feed water heater is extracted from the turbine at 50(psia) and in condensing raises the temperature of the feed water to within 11 (oF) of its condensation temperature at 50(psia) If the turbine and pump efficiencies are both 0.78 what is the thermal efficiency of the cycle and what fraction of the steam entering the turbine is extracted for the feed water heater?
