The report discusses a model, developed to describe the physical characteristics of the particulates emitted from fluidized-bed combustion (FBC) systems and to evaluate data on FBC particulate control systems. The model, which describes the particulate emissions profile from FBC, considers the attrition of the bed material and the recycling of the elutriated fines in addition to other FBC phenomena. For a given combustor design and set of operating conditions, the particle profile program projects the mass rate and size distribution of the solids in the bed draw-off and carry-over streams, as well as those emitted from particle removal devices of any given configuration. Examples of particulate emission and control are given for both atmospheric-pressure and pressurized FBC systems. The effect of calcium-to-sulfur ratio, rate of sorbent attrition, superficial gas velocity, and recycle cyclone efficiency was examined by using the model. A manual for the particle profiles program comprising a quick-reference user's section, as well as a more detailed descriptive section, is provided in the full report.
