Abstract: A refuse feeder and charging system is provided for a solid waste destruction system wherein a high temperature disposal of waste materials occurs. In such a destruction system, waste materials must be fed or charged to the upper end of a vertical gasification chamber from which the waste materials move downwardly under the force of gravity as the combustible materials are converted to molten slag and resultant gases and vapors. The refuse feeder includes a storage hopper for uniformly feeding solid waste material contained therein to a conduit means which conveys the waste material to the aforesaid gasification chamber. The storage hopper further includes an inclined vibrating pan in the bottom thereof for facilitating the uniform conveyance of waste material to the conduit means and a first set of sealing doors which may be opened and closed for purposes of batch filling the storage hopper.

Abstract: A body including a discharge passage and a runner surface extending into the passage fits in an opening provided adjacent the bottom of a furnace wherein solid material is exposed to hot gas in a manner forming a liquid waste which flows along a bottom surface of the furnace for removal. The discharge passage communicates with an outlet for removing liquid waste, and the runner surface meets the furnace bottom surface with a substantial portion of the runner surface being within the furnace. A conduit arrangement is connected to the furnace bustle pipe for supplying hot gas through a passage in the body which is directed toward the runner surface, and auxiliary fuel can be supplied to the conduit. The liquid waste material flows along the furnace bottom surface and along the runner surface through the discharge passage to the outlet, and the location of the runner surface minimizes heat loss from the liquid material. The hot gas supplied to the liquid waste material keeps it in a flowing state.
