循环水量不足是引起石横电厂#1、#2凝汽机组真空偏低的主要原因之一。对循环水泵组进行了分析改造后,循环水量大幅增加,机组真空获得了满意的效果。本文介绍了改造后的试验结果,提出了改造后的运行方式并详细分析了改造后机组的运行经济性。
Insufficient circulating water is one of the main causes for the low vacuum of # 1 and # 2 condensing units in Shiheng Power Plant. Analysis of the circulating water pump group transformation, a substantial increase in circulating water, the unit vacuum obtained satisfactory results. This paper introduces the experimental results after the transformation, puts forward the modified operation mode and analyzes the operation economy of the modified unit in detail.
