Turbine (HP) Re-heat Turbine (LP) Boiler Condenser 110 P2 PH Diagram 17 A co generating Rankine cycle is shown in Diagram 1F. 3.95% steam leaves the boiler at 450C and 4.5MPa. In the first turbine stage the steam is exponded to 600kPa. The steam is re-heated to 400C. The condensate leaves the condenser at 14kPa and 50C. The turbine has an isentropic efficiency of 0.965. 13% of the boiler steam is removed to the process heater operating at 200kPa. 36% present of the heat removed in the condenser is used to heat water in a small humidification unit. 1. Calculate the thermal efficiency, include the pump work (24) 2. Calculate the utilization factor for this cycle, include the pump work ( 3. Calculate the influence of the feed/process heater on the thermal efficiency of the cycle, include the pump work (7) 141 (7
