Corrosion Fatigue in Boiler Tubes – Thielsch Engineering

In boilers, corrosion fatigue cracking can result from the continued breakdown of protective magnetite film due to cyclic stresses. Examples of this type of failure include cracks in boiler components or tubes that are more highly stressed (such as bends or at other areas close to backstays or supports) when a boiler undergoes thermal fatigue

Three-drum boiler – Wikipedia

2019-11-11 · The move to water-tube boilers had already begun, with designs such as the Babcock amp; Wilcox or the Belleville. The three-drum arrangement was lighter and more compact for the same power. The new generation of “small-tube” water-tube boilers used water-tubes of around 2 inches (5 cm) diameter, compared to older designs of 3 or 4 inches.

Boiler (power generation) – Wikipedia

2019-10-13 · A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Finding the Root Cause of Boiler Tube Failures

Furnace water wall tubes can also fail from long-term overheat. In the case of water wall tubes, the tube temperature increases abnormally, most commonly from waterside problems such as deposits, scale, or restricted flow. In the case of either superheater or water wall tubes, eventual failure is by creep rupture.
