The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9. Pure water is neutral, with a pH of 7.0. When chemicals are mixed with water, the mixture can become either acidic or basic (alkaline).

What is the reason for keeping a boiler feed water pH

Chemical reactions happen very fast at elevated temperatures. Because of this we try to operate the boiler at the lowest possible corrosivity relative to pH (Note: this is only for boiler operating without high purity feedwater). That point is aro

ph control of boiler water - spartan controls


2015-2-17 · A major element of boiler water treatment is controlling corrosion by keeping the boiler water pH slightly alka-line. Alkaline pH causes an oxide film to form on the boiler tube surfaces that protects the base metal from further corrosion and allows breaks in the film to heal efficiently. pH control involves feeding sodium hydrox-

The importance of pH in steam-boiler water - Heating …

If the pH is lower than that, the water will start eating the pipes. If it’s higher than that, the water won’t corrode metal, but it may begin to foam, and that’s not good. Hold that thought for a moment. You’re on a job and you have a steam boiler that’s taking on a lot of feed water because the system has leaks.

Controlling the PH of water is the first step towards boiler treatment. We all know that if PH is below 7 the solution is acidic and above 7 it’s alkaline. For boiler water PH is maintained between 11-11.8 and that of feed water between 7-9. Effects. If either of the values increases, water will accordingly become acidic or alkaline, leading
