Carbon dioxide attack in boilers - Lenntech

Corrosion is the principal effect of dissolved carbon dioxide. The gas will dissolve in water, producing corrosive carbonic acid: H 2 O + CO 2 çè H 2 CO 3 çè H + + HCO 3-. The low pH resulting from this reaction also enhances the corrosive effect of oxygen. In boiler systems, corrosion resulting from carbon dioxide is most often encountered
