  • Apparatus for incinerating combustible material
    Patent number: 4859177
    Abstract: A rotary kiln device for incinerating combustible materials such as municipal and commercial waste materials. The kiln is a co-current gas-material flow apparatus. The kiln is divided by means of a dam into a drying zone and a combustible zone. Waste material is retained within the drying zone sufficiently long so that that moisture contained in the material is driven off. Air for combustion is supplied directly to the combustion zone, bypassing the drying zone so that self-sustaining combustion may take place.
