Rankine Cycle Power Plant Analysis Power-Turbine The Power Plant Analysis shown below is for the purpose of showing how Rankine Cycle efficiency is affected by Source (Boiler) Temperature and Sink (Condenser) Temperature A 37 MW Power Plant is analyzed with conditions established in the Power Plant Project document Please note-If there are no pipe losses, oulet of each component=Inlet of next component (i.e. Property 3=Property 3') otherwise the properties will be different (i.e. In this case Boiler Outlet 1 is not equal to Turbine Inlet 1) Alll Qdot and Wdot values are in kJ/s (kW) unless the heading is in MW Net MW Output 37 Case 1-High Boiler Temperature/Pressure and Low Condenser Temperature/Pressure Turbine In-1' Pressure (kPa) Temperature (deg.
