APPLICATION OF AGENT-DOSING TECHNOLOGY IN THE INTERNAL COOLING WATER SYSTEM FOR LARGE GENERATORS[J]. Thermal power generation, 2001, (1): 60-62. DOI: 10.19666/j.rlfd.2001.01.019.
大型发电机内冷水系统加药处理技术的应用
摘要
以潍坊电厂 1号机组 (30 0MW)为例
介绍了发电机内冷水系统采用化学清洗与MBT预膜的工艺条件和处理结果。实践表明 :发电机投入运行后
继续向内冷水中加入MBT
其浓度控制在 0 .5~2 .0mg/L
就可达到防腐防垢的目的。
Abstract
Taking 300 MW generating set No 1 in Weifang Power Plant as example
the technological condition and handing result of applying chemical cleaning and MBT film-formation in the system of generator’s internal cooling water are presented.The practice indicates that the purpose of anti-corrosion and anti-scaling can be realized after putting the said generator into operation by continuously dosing MBT into internal cooling water
and keeping the density of MBT in the range of 0.5~2.0 mg/L.
