The major materials issue in the commercialization of fluidized-bed combustion (FBC) systems for utility cogeneration applications is the corrosion/erosion degradation of in-bed components. To examine this issue, pertinent materials information was collected from 13 sources that included 16 different experimental fluidized-bed combustors (four pressurized, the other atmospheric), and a detailed analysis of the data was performed. The data analysis confirmed that austenitic stainless steels (notably Types 304 and 310) and cobalt-base alloys (notably Haynes 188) are superior to nickel-base alloys. Type 347 stainless steel and Incoloy 800H are questionable from the point of view of metal wastage. Very limited data are available for claddings and coatings. The correlations of the corrosion rate data presented in this paper for several of the more promising alloy candidates for air heater application provide guidelines for the selection of materials with reasonably assured performance in a corrosive environment.
