What is the reason for keeping a boiler feed water pH

This is one of the most asked about and often misunderstood applications for pH control in the chemical feed. Neutralizing amines are used in boiler water treatment to control condensate return line corrosion. Here's why: They are alkaline, which means they can neutralize acids that can form in the condensate by raising the pH.

Reasons why steam boiler water level too high and

Why is the pH in my boiler water high? 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. Why pH is important in boiler water? pH maintenance of the feed, boiler and condensate system is essential for corrosion control.

Considerations for High Pressure Boiler Chemical Treatment

typically, the boiler pH is 0.2 to 0.3 units lower that the feedwater pH value when ammonia is used. In addition the boiler water has essentially no capacity to buffer the pH in event of feedwater contamination. Consequently, where possible, it is advisable to use an amine with a low distribution ratio at boiler water temperature.
