Closed feedwater heater temperatures

WebThe cooling water experiences a temperature increase from 16 to 28°C, with negligible pressure drop, as it passes through the condenser. The utility Engineers of the power plant have modified the cycle to include one closed feedwater heater using extracted steam at Per MPa and one open feedwater heater operating at Pof MPa. 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 output, and the thermal efficiency are to be determined. Assumptions1Steady operating conditions exist. 2Kinetic and potential energy changes are negligible.
