蒸汽凝结水供暖系统的腐蚀原因及防腐措施１９８８年我厂将蒸汽供暖系统改造为凝结水供暖。运行３ａ后，先后发现大部分钢制散热器发生腐蚀，系统ｐＨ值约５．０左右。产生腐蚀的主要原因为：①锅炉给水中游离的ＣＯ２和Ｏ２进入蒸汽即冷凝水中；②炉水中的部分Ｎａ２ＣＯ... Corrosion Causes and Anti-corrosion Measures of Steam Condensate Heating System In 1988, our factory transformed the steam heating system into condensate heating. After running 3a, it was found that most of the steel radiators were corroded and the system pH was about 5.0. The main causes of corrosion are as follows: 1 The free CO2 and O2 in the boiler feed water enter the steam, ie, the condensate water; 2 Part of Na2CO in the boiler water...
