WebCh 10. Rankine Cycle. A steam power plant operates on an ideal reheat-regenerative Rankine cycle with one open feedwater heater, one closed feedwater heater, and one reheater. The fractions of stream extracted from turbines and the thermal efficiency of the cycle are to be determined. All the components in the cycle operate at steady state. WebQuestion: One modification of the Rankine cycle is to add a feedwater heater (called regeneration). An open feedwater heater (OFW) of the sort shown in the diagram is considered to be a constant pressure mixing point. It should be considered to be well-insulated. The feed that comes directly from the turbine has enthalpy of 2,380 kJ/kg.
