由于硫酸盐和硅酸盐等难溶垢的存在 ,工业锅炉单用酸洗的方法是难以一次性清洗干净的 ,即使除垢率达到了《低压锅炉化学清洗规则》中的要求 ,也会有残留的水垢 ,给锅炉安全经济运行带来不利影响 .本文对残留水垢提出了可在锅炉日常运行中清洗的方法 .
Because of the presence of difficult-to-dissolve scale such as sulfate and silicate, industrial boilers alone can not be cleaned in one step with a single pickling method. Even if the scale removal rate meets the requirements in the Low Pressure Boiler Chemical Cleaning Regulations, there will be The remaining scale, to the safe and economical operation of the boiler adversely affected.This paper proposed the residual scale can be cleaned in the daily operation of the boiler.
