Determine the thermal efficiency and the required steam flow rate [kg/s] for a reheat-regenerative steam power plant which is to produce 200 MW of electricity. The turbine drives a generator with an efficiency of 94%. The turbine inlet conditions are 160 bar and 590 C; after reheat the steam is at 100 bar and 590 C; one closed heater is at 30 bar; an open feedwater heater is at 1.5 bar; and the condenser pressure is 0.10 bar. The turbine and pump efficiencies are 100%. The terminal temperature difference from both heaters is 3 C, and the drain from the closed heater is trapped to the open heater. The extracted steam exiting the closed heater is saturated liquid Also sketch the cycle on a T-s state diagram.
