Abstract
An apparatus and method for cleaning hot gases containing gaseous contaminants and particulate contaminants, including sticky components where a vessel contains a walled housing and a divider which separates an enclosed area therebetween into dirty and clean gas sections. A moving bed of coarse particulate material is contained in the walled housing with gases, after flow through a portion of the moving bed, passing into the second section where hollow, ceramic, barrier filter units remove the remaining solids therefrom. Sorbent material removes gaseous contaminants, sticky components are retained in the moving bed of coarse particulate material, and the filter units remove fines so that the hot gases are discharged clean from the vessel.
