Steam at 150 bar, 550 C is expanded in a high-pressure turbine to 20 bar when it is reheated to 500 C and expanded in intermediate-pressure and low-pressure turbines to condenser pressure of 0.075 bar. There are five feedwater heaters, one extraction from high-pressure turbine at 50 bar, 3 from intermediate pressure turbine at 10 bar, 5 bar and 3 bar, and one from low-pressure turbine at 1.5 bar. The middle heater is the deaerator, and all others are closed heaters the power output if the steam flow rate is 300 t/h. Take TTD=0 for all the heaters.
