... of the location of the failure to the locations of other system components—for example, the location of a tube rupture in relation to those of burners or soot blowers—is an important phase of on-site examination. It is usually helpful for the individual making the on-site examination to have an assortment...

... superheater tubes undergo damage in the form of high-temperature degradation as the microstructure decomposes, oxidation forms on the inside diameter, and the tube wall thins. This damage would not be considered a failure until the tube ruptures. However, monitoring the damage is necessary to allow tube...
