摘　　要：凝汽器真空与端差是影响凝汽器热力特性的重要指标。凝汽器端差是机组“达设计值”的一项主要指标,也是冷端优化的重要一环,端差治理是目前国内火电企业普遍面临的一大难题。本文对此类缺陷进行了分析、总结,以方便同型机组及时消除类似缺陷,避免类似缺陷的发生。The vacuum and end difference of condenser are important indexes that affect the thermodynamic characteristics of condenser.The end difference of condenser is not only a main index of"reaching the design value",but also an important part of cold end optimization.The treatment of end difference is a common problem faced by domestic thermal power enterprises.This paper analyzes and summarizes these defects in order to eliminate and avoid similar defects in time.
