The model described in Part I is applied to study an atmospheric fluidized‐bed coal combustor. Extensive case studies are investigated on the effects of: enhanced grid region heat and mass transfer; bed void fraction; emulsion phase temperature; elutriation rates; reaction rate parameters; feed particle‐size distribution; and particle superheat. Comparison is made with experimental results reported by Babcock and Wilcox. Proper representation of the grid region and use of actual feed distributions are shown to be essential to predicting combustor performance. Better particle elutriation and single‐particle combustion submodels are found to be key requirements for improved combustor modeling.
