Open and closed feedwater heater thermo
WebThe exergy destruction in the regenerator–mixer system can be further reduced if the closed feedwater heater is replaced with an open feedwater heater (OFW). This is in fact a direct contact heat exchanger. An improved Rankine plant design of regenerative type is introduced in Figure 5.18. WebThe temperature of the steam at the inlet of the closed feedwater heater, the mass flow rate of the steam extracted from the turbine for the closed feedwater heater, the net power …

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.
