The normal pH range for boiler water is typically between 10.5 to 11.5. This alkaline range is important because it helps to prevent corrosion within the boiler system. A higher pH indicates fewer hydrogen ions in the water, which reduces the risk of corrosion and promotes better scaling properties. This pH level also aids in the effectiveness of certain conditioning chemicals that are used to manage water quality in the boiler.

Boiler water that falls under the specified pH range typically ensures an optimal environment for steam production and boiler operation while minimizing issues related to corrosion and scale formation. Maintaining proper water chemistry is crucial for the longevity and efficiency of the boiler, making understanding pH levels an essential aspect of boiler operation and maintenance.
