The overall program objective is to determine the effect of operating and design parameters of fluidized-bed combustors (FBCs) on in-bed tube metal wastage. The overall program approach is: (1) develop an experimental approach for acquiring tube metal wastage data under controlled and measurable conditions that reproduce the combined local mechanical and chemical environment that exists at the FBC in-bed tube surface, (2) document the precise local mechanical and chemical environment at the in-bed tube surface of an FBC and correlate these local data with global bed operating and design parameters, (3) use the above experimental approach over the entire range of documented local environments to develop a complete database of tube metal wastage results, and (4) analyze this database to determine the effect of operating and design parameters on in-bed tube metal wastage. The project consisted of a literature review, facility design and fabrication, experimentation, and data analysis. The following chapters of this report summarize each of these activities. 80 refs., 47 figs., 11 tabs.
