Failure Analysis of Water-Wall Tubes in the High-Pressure ...

Based on the failure process of the boiler water-wall tubes and the experimental results a conclusion was drawn that the failure of water-wall tubes was mainly caused by pitting corrosion. Sulfide and chloride attack was the major cause of localized pitting corrosion on the inner surface and the outer surface damage was mainly due to the synergism of high temperature sulfide corrosion and flue gas erosion.

Engineer's Guide to Boiler Tube Inspections | Engineering360

Plant staff is often the first to observe issues such as increasing boiler make-up water levels or the characteristic sounds of superheater or reheater tube leaks. Occasionally tube leaks can be seen via boiler observation ports or high-temperature thermography cameras. And acoustical technologies enable incipient leak identification.
