  • Patent number: 5445088
    Abstract: This abstract describes a process for the complete oxidation of municipal refuse and certain hazardous materials. The facility to accommodate the process consists of a completely enclosed, rotating, cylindrical kiln wherein solids, liquids, and gaseous compounds are simultaneously oxidized. To supplement the burning process, natural gas will be injected into the kiln chamber through a regulatory apparatus. Within the oxidation chamber, temperatures of 3200 degrees F., plus, will be maintained by injecting a regulated flow of pure oxygen, as an oxidant, to ensure the complete oxidation of all materials. After suitable preparation, solids and liquids will be introduced into the kiln chamber through an enclosed, sealed, apparatus i.e., screw conveyor, to control refuse volumes. During the oxidation process, the refuse materials will be kept in suspension for an adequate dwell time by the tilted orientation and rotating operation of the kiln apparatus.
