针对热力厂及宾馆、饭店蒸汽锅炉产生的冷凝回水中由于二氧化碳的腐蚀引起回水“发红”不能回用的问题,采用在蒸汽中加入中和胺,提高 pH值的方法,可以有效的提高回水回收率,经济效益显著。

The steam boilers used in thermal stations and hotels- generate condensed return water, Due to the corrosion caused by carbon dioxide, the return water turns red and can not be re-used.The solution to thisproblem is adding neutralizing amine to the steam to raise the pH level of the condensed water.This solution effectively raises the water-recovery rate and brings significant economic benefits.
