摘要

Fireside corrosion shortens the service life of tubes in coal-fired and oil-fired boilers.Waterwall and superheater/reheater tubes may experience substantial wall loss as a result of fireside corrosion.Waterwall tube failures due to fierside corrosion are less common than failure of superheater/reheater tubes.Therefore,comments respective to waterwall tube failures are addressed only in the introduction section of this paper.Mechanisms of failures involving fireside corrosion of superheaters/reheaters are presented as Case Studies using actual laboratory analysis data.Available approaches to minimize fireside corrosion of superheaters/reheaters are reviewed.
