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

The Importance of Boiler Water and Steam Chemistry

The Importance of Boiler Water and Steam Chemistry. Steam Purity. Purity or chemistry requirements for steam can be as simple as a specified maximum moisture content, or can include maximum concentrations for a variety of chemical species. Often, for low pressure building or process heater steam, only a maximum moisture content is specified.
