Abstract

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.

Key words: feed water temperature, load, coal consumption rate, measure
