What chemical can be added to boiler water to increase pH?

Adding sodium hydroxide to boiler water is a common practice for increasing pH levels. Sodium hydroxide is a strong alkaline substance that, when dissolved in water, raises the concentration of hydroxide ions in the solution. This increase in hydroxide ions leads to a higher pH, which is crucial in boiler operations to prevent corrosion and scaling. Maintaining an appropriate pH level is essential for optimal boiler performance and longevity, as it helps protect boiler materials from acidic conditions that can lead to damage.

The choice of sodium hydroxide as a pH adjuster is tied to its effectiveness and the desirable alkalinity it imparts to the water. High pH levels help in minimizing the formation of corrosive elements, ensuring better efficiency and safety of the boiler system.
