ABSTRACT:
A combustion device for the pyrolytic destruction and gasification of industrial or other wastes, or lower sulfur fuels, is provided which includes an elongated cylindrical kiln body. Air is introduced into the kiln body by a plurality of pipes which define different combustion zones therewithin. A sorbent such as pulverized limestone may be introduced into each zone for reaction with the feedstock material to reduce undesirable flue emissions. The pipes are oriented within the kiln body to sweep the feedstock along the kiln body in a generally cyclonic pattern of torroidal shape and cross-sectional contour. The kiln may be rotated at various speeds corresponding to the force of the introduced combustion air to fluidize and entrain the feedstock material to be combusted.
