氧化铁垢就是垢中氧化铁含量超过60%～70%以上的水垢,或以氧化铁为主要成分的水垢。目前,高温高压锅炉对补给水采取了二级脱盐处理,已经避免了低压锅炉的那种以碳酸盐或硅酸盐为主要成分的结垢情况,而是以氧化铁垢为主,氧化铁垢已经成为高温高压锅炉安全运行的最大危害。 Iron oxide scale is scale in the iron oxide content of more than 60% ~ 70% scale, or scale as the main component of iron oxide. At present, the high temperature and pressure boilers take secondary desalination of make-up water, which has avoided the kind of scale formation with carbonate or silicate as the main component of low-pressure boilers. Instead, the scale mainly consists of iron oxide scale, iron oxide Scale has become the biggest harm to the safe operation of high temperature and pressure boiler.
