Abstract

The moving characteristics of coal and RDF in a actual swirl-type precalciner were studied by numerical simulation. The gas phase is expressed with k- two-equation model and the solid phase is expressed with discrete phase model (DPM). The results show that the coal, carried by the gas flow which rises spirally in the precalciner, moves spirally along the wall of the column section of the precalciner, and the RDF rises spirally around the center axis of the precalciner. Since the RDF gatherers in the upper region, being away from the high concentration region of the coal, the initial combustion of RDF will affect the initial combustion of coal weakly. What we obtain in this study will provide theoretical basis to explore deeply the co-combustion mechanism and interactive influence between pulverized coal and RDF in the precalciner.
