摘要
针对直流炉发电机组易发生流动加速腐蚀(FAC),造成水汽系统中设备的结垢、积盐速率偏高等问题,结合案例分析介绍了FAC机理、铁腐蚀产物迁移过程及FAC抑制方法等。结果表明通过给水加氧处理(OT)可有效抑制直流炉发电机组FAC发生。
To solve the problem that flow accelerated corrosion(FAC)is easy to occur in once-through boiler units,which may result in a higher rate of scaling and salt accumulation in the equipment of related water-steam systems,an introduction was presented on the FAC mechanism,the migration process of iron corrosion products and the FAC inhibition methods,based on case analysis.Results show that the FAC in once-through boiler units could be effectively inhibited by feed water oxygenation treatment(OT).
