摘　　要：某火力发电厂发电机组凝结水系统并行除氧器水位自动调节系统和凝结泵变频自动调节系统,机组低负荷工况运行时,由于除氧器水位调节阀开度过小,系统存在很大的节流损失,凝结泵变频调节实际的节能效果大打折扣。探索一种低负荷或深度调峰条件下火力发电机组凝结水系统除氧器水位自动调节的方法,以达到降低节流损失,降低机组能耗的目的。The condensate system of a thermal power plant condensate system paralleled deaerator water level automatic adjustment system and condensate pump frequency automatic adjustment system,in low load operating conditions,due to the deaerator water level adjustment valve opening too small,the system had a large throttling loss,the actual energysaving effect of condensate pump frequency adjustment was greatly reduced.This paper explored a method of automatic adjustment of deaerator water level in condensate system of thermal power generator set under low load or deep peaking shaving conditions,in order to achieve the purpose of reducing throttling loss and energy consumption of the set.
