Abstract
This research project is intended to provide an understanding of the behavior and detailed information useful for the design of atmospheric fluidized combustors. Fluidized beds operated at room temperature are used to simulate the behavior of hot fluidized bed combustors, and are instrumented to provide detailed information about bubble movement, solids mixing, bed-to-tube heat transfer, gas flow and mixing and forces on the tube array. Detailed data are collected on elutriation of fines, and the de-fluidization and re-fluidization characteristics of a portion of a large bed. Physically reasonable models for tube-to-bed heat transfer, solids mixing, gas flow and mixing, and elutriation coupled with particle attrition are developed and compared with experimental data.Keywords
