pH Treatment | CleanBoiler.org

A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic (alkaline). Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. Careful control of boiler water chemistry can

Controlling TDS in the Boiler Water | Spirax Sarco

An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as: Example 3.12.3. A boiler water sample has an unneutralised conductivity of 5 000 μS/cm at 25°C.

2015-9-19 · pH Control The pH value is a number between 0 and 14, which indicates the degree of acidity or alkalinity of the water. A pH value of 7 is neutral with values below 7 being acid and above 7, alkaline. If the boiler water is acidic, then corrosion of the boiler metal will occur. To prevent this corrosion, the boiler water should be kept alkaline.
