摘　　要：首先阐述循环水系统优化运行的目标值——最佳真空确定的原理;然后计算分析了凝汽器清洁情况对最佳真空的影响;最后利用凝汽器综合清洁系数来体现凝汽器水侧管壁脏污程度、汽轮机真空系统严密性对最佳真空的影响,提高了最佳真空的确定精度、得到的循环水系统优化方式更合理。Firstly, it was expound that circulated water system optimize operation target value -optimum vacuum principle. Afterward, it was calculated and analyzed condenser cleanliness condition Influence to optimum vacuum. Finally, condenser cleanliness coefficient was used to embody cleanliness degree about condenser tube wall of water side and vacuum system tightness which Influence to optimum vacuum. Thus optimum vacuum confirm precision is improved and circulated water system optimize operation model is more reasonable.

关 键 词：凝汽器 循环水系统 优化目标 清洁系数
