Despite using demineralized feedwater, water related tube failures still occur in some industrial boilers. The failures occur due to overheating or corrosion. The corrosion may be either caustic or acidic attack. These tube failures can be avoided by employing water treatment programs that minimize deposition and maintain boiler water chemistry that does not become aggressive to the boiler steel when it is concentrated. The best boiler water chemistry to maintain, congruent phosphate-pH treatment, equilibrium phosphate treatment or phosphate treatment, depends on individual system operating conditions. Experience indicates that boiler deposition and boiler water chemistry control are the most significant factors affecting boiler tube failures.
