The Boiler Re-Tube! Why, When, and How is it Done? Part I

Fire­tube steam boilers are designed for the purpose of industrial scale heat exchange in order to heat saturated liquid entering the control volume to a saturated gas. Exiting gas leaving the control volume may experience a pressure drop when returning to atmospheric pressure.

Water Maintenance Essential to Prevent Boiler Scaling

Elements contained in hard water, like calcium and magnesium, form a buildup on the components of the boiler. Preventing this damaging accumulation of hard water deposits is crucial to maintaining the effectiveness of a boiler. Hard scale buildup, even a seemingly insignificant one of 1/8 of an inch, can reduce efficiency by up to 20-25% due to

Steam Boiler Scale Prevention and Cleaning Services

When untreated boiler water is heated, this calcium and magnesium will precipitate from the solution to form hard scale on the tube surfaces. In addition to the overheating and eventual failure of the boiler tubes due to scale, efficiency is also decreased in the short-term because of the scale's insulating effect on the heat transfer surfaces.

An Introduction to Treatment of Steam Boiler Water

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.
