The fireside corrosion potential of commercial boiler tube alloys at elevated temperatures when exposed to the combustion products from a series of coals was investigated. The results of the laboratory and field tests were previously reported. In a supplementary phase of the program, the effect of chloride on similar alloys while firing a naturally occurring high chloride Midwestern bituminous coal in the same laboratory furnace were studied. On the basis of exposure in the convection pass at temperatures from 1100 to 1700 F, Inconel Alloy 690 was very good while Incoloy 800 and Tp-310 S.S. were good transitional materials. Poor materials were T-22, 316S.S., Inconel 617, and Inconel 671. 4 refs.
