| Abstract: | The feed water temperature is an important economical index,which influences on the coal consumption rate directly,and finally influences on the generating cost.The structure,operation characteristics and thermal insulation of high-pressure heater,low-pressure heater,pipeline and valves were analyzed;and based on this analysis,the factors influencing on feed water temperature were found;the measures for increasing the feed water temperature were determined.By continuous perfection of relevant measures,the economical benefit of the unit operation can be further increased. |
