A steam power plant works on the Rankine cycle operates between the pressure limits of 30 bar and 0.1 bar. The boiler has an efficiency of 92% is capable of producing steam of 16-degree superheat with a feedwater temperature of 30°C. The net capacity of the plant is 25 MW. The efficiency of the pump and turbine is 95% and 92% respectively. The temperature of the water entering and leaving the condenser is 30°C and 38°C. The pressure in the condenser is 675 mm of Hg. Determine the following with neat T-S and line diagram. Take Calorific value of fuel is 42000 kJ/kg and the barometric reading is 760 mm of Hg. 1. Equivalent evaporation of boiler. 2. Mass flow rate of steam 3. Mass flow rate of fuel 4. Condition of steam at the exit of the turbine. 5. Vacuum efficiency of the condenser. 6. Condenser Efficiency 7. Rankine efficiency
