4.3 Boiler water should be maintained at pH 11. Generally, the higher the pH (basic), the less soluble some solids are in the water. The lower the pH (acidic), the more soluble these solids are. 4.3.1 Hard scale is most often formed when dissolved solids are deposited directly on a heat transfer surface as water changes to steam.

High-Purity Boiler Water pH Measurement
Mar 01, 2019 · As long as the conductivity is greater than 50µS/cm at 25C and the suspended solids concentration is low, the use of a general-purpose pH sensor is ideal. The cutoff point between low-
A common recommendation is to maintain boiler water at 8.5 pH. Acidic water is corrosive. Alkalinic water is more prone to scaling. Alkalinity is a measure of the bicarbonate (HCO3), carbonate (CO3) and hydroxyl (OH) ions in the water. pH and alkalinity ratings are NOT the same and are NOT proportional. pH is rated on the Scale and alkalinity is measured in parts per million (ppm).
