An investigation was carried out on the fireside corrosion potential of commercial boiler tube alloys at elevated temperatures when exposed to the combustion products from a series of coals. The results of these laboratory and field tests were reported previously. In some supplementary tests, the effect of chloride was investigated on similar alloys while firing a high-chloride mid-western US bituminous coal in the same laboratory furnace. On the basis of exposure in the convection pass at temperatures from 1100-1700 F, Inconel Alloy 690 was found to have very good corrosion resistance, while Incoloy 800 H and Tp-310 s.s. were good transitional materials. Poor materials were T-22, 316 s.s., Inconel 617 and Inconel 671.
