Water Handbook - Preboiler & Industrial Boiler Corrosion

In high-purity systems, raw water in-leakage (e.g., condenser leakage) lowers boiler water pH when magnesium hydroxide precipitates, resulting in corrosion, formation of atomic hydrogen, and initiation of hydrogen attack. Coordinated phosphate/pH control can be used to minimize the decrease in boiler water pH that results from condenser leakage.

Boiler Layup Procedures Water Technology Report

Jul 24, 2017 · This procedure involves filling the boiler, feedwater heaters, and deaerators with demineralized water, treating the water with a chemical oxygen scavenger, and adjusting the pH between 10 and 11. For boilers without superheaters or for boilers with drainable superheaters, sodium sulfite and caustic soda are generally used for this purpose.
