In order to determine the resistance of metal alloys to high temperature erosion-corrosion in fluidized-bed combustors, sub-sized finned tube bundles were installed in operating commercial fluidized-bed reactors used for the incineration of municipal sewage sludge. The alloys tested were Type 304 stainless steel, Incoloy 800H, Incoloy 601, Inconel 690, and Haynes 188. At the end of the test runs there was no visible evidence of deposits or of metal wastage. Metallographic and microprobe analysis revealed shallow internal attack, primarily oxidation, with some slight sulfide penetration. Differences in corrosive attack between alloys was minimal. The sulfidation attack on the tubes was not significant. Possible reasons for this are discussed. (JSR)
