A large engineering design firm is designing a superheated steam turbine system which has an available boiler that can supply steam to the turbine at 80 bars and 600C. The Rankine cycle is planned to have three regenerative heaters. One engineer suggests that these should be placed at equal pressure increments except for the exhaust which is set to 1.0 bar. The pressures would be for reheat #1 at 60 bar, reheat #2 ant 40 bar, and reheat #3 at 20 bar, with the steam leaving the turbine at 1.0 bar. A second engineer disagrees and says that the thermal efficiency would be higher if the reheat occurs at pressures with equal increments of enthalpy drop. You are tasked with determining which approach has the higher cycle efficiency. Assume pump work is small and can be neglected. Cool Prop Temperature (C) 100 450 300 250. 200 150 100 50 6 0 Which is more efficient, equal pressure increments or equal enthalpy increments? 6 8 2 13 m1 3 12 11 m2 10 m3 4 1-m-m2-m3 5 4 Entropy (kJ/kg/K)
