  • Sludge handling and feeding system
    Patent number: 6176187
    Abstract: A system for handling aqueous sludge to a combustor such that pollutant emissions associated with combustion operations, e.g., cement manufacturing, are reduced. Sludge is accumulated at a receiving site from where it is transported to a sludge conduit. The sludge is then introduced from the sludge conduit into a combustion apparatus at a point effective to reduce pollutant emissions produced by the combustion operation.
