This paper describes efforts to estimate the potential effects of chloridebearing North American coal on fireside corrosion in utility boilers. Chloridebearing North American coal is similar to British coal, and this study draws heavily on published British data and experience. Generally, chloride effects on furnace wall tubes are attributed to chloride-accelerated sulfidation, and the accelerating effect appears to increase with temperature. This study concludes that the tubes most affected are those in contact with incompletely oxidized, sulfur-bearing combustion gases.
