Exergy analysis of high-pressure feed water heating system at three power plant loads

The paper presents an exergy analysis of high- pressure feed water heating system from cogeneration power plant at three different loads. Analyzed system consists of feed water pump, feed water heater and pressure reduction valve. Each feed water high-pressure heating system component has the highest exergy destruction at low plant load-188.96 kW for feed water pump, 1064.73 kW for feed water heater and 93.57 kW for pressure reduction valve. Feed water pump has the lowest exergy efficiencies which range is between 77.11 % and 81.35 %, feed water heater has exergy efficiencies between 86.07 % and 89.82 %, while pressure reduction valve has the highest exergy efficiencies (between 93.78 % and 95.67 %).
