Hardness - Hard water does not foam. However, boiler water is deliberately softened to prevent scale formation, and this gives it a propensity to foam. Colloidal substances - Contamination of boiler water with a colloid in suspension, for example. milk, causes violent foaming. Note: Colloidal particles are less than 0.000 1 mm in diameter, and

Boiler Water Treatment Part 2 – Internal Treatment

These chemicals are used to raise the pH of the water within the boiler. In some circumstances the natural alkalinity of the feed water will be adequate to keep a high enough level of pH within the boiler. Generally these products should be dosed into the boiler feed tank, especially if sodium bisulphite is used, as this is acidic.

Boiler Tube Failures

Causes: Tube damage occurs due to the combination of thermal fatigue and corrosion. Corrosion fatigue is influenced by boiler design, water chemistry, boiler water oxygen content and boiler operation. Leads to the breakdown of the protective magnetite on the ID surface of the boiler tube. The loss of this protective scale exposes tube to corrosion.
