摘要
针对当前部分超(超)临界机组凝结水系统所面临的流动加速腐蚀问题,从FAC产生机理出发,对影响FAC速率的因素进行总结,讨论抑制流动加速腐蚀的措施。针对超(超)临界机组因凝结水含氧量问题而发生FAC的现象,寻找合理的解决方案,即在凝结水系统中选取合理的部位,分别实施加氧处理和注入联氨。
In view of flow accelerated corrosion problems faced by the condensate system of the current part of the su-per （super）criticality unit, starting from the FAC mechanism to summarize the factors influencing FAC rate, discuss the measure to restrain the flow accelerated corrosion. In view of the phenomenon of FAC produced by oxygen content of conden-sation water in the super （super） criticality unit, looking for a reasonable solution, in other words,oxygen and hydrazine were injected respectively in the reasonable part of the condensate system.
