Boiler tubes can fail due to problems on either the fire-side or the water-side of the tube. Part 1 of this article discussed fire-side failure mechanisms and measures for preventing failures. Here the author focuses on the tubes' water-side. The term water-side mechanisms'' refers to damage on the water side of the boiler tube (as opposed to the fire side). However, the water itself is often not the culprit. Water-side corrosion mechanisms may be classified into two major categories: physical and chemical. Physical mechanisms include steam blanketing and overheating. Chemical mechanisms include: deposition; caustic, acidic, and chelant corrosion; oxidation; and hydrogen embrittlement.
