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.

Testing Alkalinity In Boiler Water - Taylor Technologies

Typically, as boiler operating pressure increases so does the need for higher purity water. At the same time, water treaters need to maintain a minimum level of OH alkalinity (generally, over 150 ppm as CaCO 3) to prevent scaling tendencies while ensuring excess alkalinity doesn't interfere with other chemical treatment components. In cooling water, treatment professionals aim to control alkalinity (and pH) to
