- Title
Chloride Pitting of Steam Generator Boiler Coils.
- Authors
Ifezue, David
- Abstract
In this case study, pitting observed on boiler coil samples were analyzed. Chloride pitting was confirmed by chlorides identified in energy-dispersive X-ray (EDX) spectra and maps. The pitting failure was caused by initial chloride fluxing of the oxide/scale layering, followed by a chloride concentrating mechanism. The observed pitting can be prevented by water treatment to eliminate the halide ions followed by boiler scale and deposition control treatment.
