某电厂S109FA机组在运行过程中，突然出现机组除盐水补水量增大的异常现象，采用运行技术手段对机组除盐水补水量异常增大的分析判断，利用质量守恒定律分析，得出余热锅炉低压系统泄漏。结合同类型电厂的调研对比及广东电网公司电力科学研究院的分析，得出流动加速腐蚀是造成低压蒸发器泄漏的原因。根据机组的实际运行情况提出相应的解决方案，保证了机组的安全、经济运行。
某電廠S109FA機組在運行過程中，突然齣現機組除鹽水補水量增大的異常現象，採用運行技術手段對機組除鹽水補水量異常增大的分析判斷，利用質量守恆定律分析，得齣餘熱鍋爐低壓繫統洩漏。結閤同類型電廠的調研對比及廣東電網公司電力科學研究院的分析，得齣流動加速腐蝕是造成低壓蒸髮器洩漏的原因。根據機組的實際運行情況提齣相應的解決方案，保證瞭機組的安全、經濟運行。

With the help of operational and technological means , this essay introduces the analytic judgment of the abnormal augmentation of the amount of the desalted water supplement of the S 109FA unit in a power plant during its operation .Relevant analysis based on the law of conservation of mass reveals the leakage of the low -voltage sys-tem of the exhaust-heat boiler .The surveys in power plants of the same type together with the analysis performed by Electric Power Research Institute of Guangdong Power Grid Corporation show that the leakage of the low -pressure e-vaporimeter is caused by the flow accelerated corrosion .According to the operation of the unit ,this essay puts for-ward relevant solutions to ensure its safe and economical operation .
