A steam power plant is based on the Rankine cycle with reheat (refer to the figure below). Steam is produced by the boiler/superheater (H-1) at 100 bar and 600 C at a rate of 2.5 kgs. This is expanded to 10 bar in the turbine T-1 and then reheated to 600 °C in heater H-2. The steam is then expanded in turbine T-2 to a pressure of 0.1 bar. The steam is then condensed in condenser (C-1) which operates at...
