Model of solid gas reaction phenomena in the fluidized bed freeboard
Journal Article

A comprehensive model incorporating elutriation, entrainment and reaction is presented to describe the chemical reaction and hydrodynamics occurring in the freeboard of a fluidized bed. A comparison of experimental data on the amount of particles elutriated and the concentration profiles of SO/sub 2/ and NO /SUB X/ obtained from the freeboard of fluidized bed coal combustion (FBC) by the Babcock and Wilcox Company with the calculation based on the proposed model to include the effect of interaction among the entrained particles is desirable. More experimental data with chemical reactions in the freeboard are needed to validate the model for applications to fluidized bed catalytic reactors.
