扬州电厂330MW汽轮机组闭冷水系统节能改造

Energy save transformation of closed cooling system of 330 MW steam turbine unit in Yangzhou Power Plant

为研究330MW机组闭冷水系统在不同季节下的用水量,分析了江苏华电扬州发电有限公司闭冷水系统2012年全年的运行状况。基于闭冷泵的特性及选型原则,分析了选用小泵替代原大泵运行的经济性,提出了在闭冷水系统中增加一台小泵运行从而降低系统能耗的节能方案。改造结果表明:选用合适的小泵运行有效降低了闭冷水系统能耗,系统运行状况良好。

In order to study the water consumption of the closed cooling system for the 330 MW unit under different seasons,the operation conditions of closed cooling water system in the whole year 2012 Jiangsu Huadian Yangzhou Power Generation Corporation Limited were analyzed. Based on the features and selection principle of the closed cooling pump,the economy of small pump instead of the original large pump were analyzed. The energy saving plan of adding a small pump in closed cooling water system to reduce the system energy consumption were advanced.Transformation results showed : suitable small pumps can reduce energy consumption of closed cooling water system and the system is running in good condition.
