One purpose for this study was to show that Mississippi lignite, with a high sulfur content, would burn in a fluidized bed. A second purpose was to determine if the alkaline minerals in the ash would capture sulfur dioxide emitted by the burning lignite. The experimental study revealed that sulfur was captured by the ash. The amount of capture depended on the operating conditions of the combustor. It was determined that limestone injection into the bed would be necessary to meet the environmental emission standards. The trends of the sulfur capture with operating conditions of the combustor are explained by using a pseudo steady-state model developed for combustion of a porous single char particle.
