ABSTRACT:
According to the present invention, a sealing chamber is provided into which a noncombustible residue from an incinerator, furnace or the like is moved. The residue may be sprayed with a liquid upon entering the sealing chamber to effect cooling and compaction of the residue. The sealing chamber is provided with a vibratory discharge mechanism which serves to convey the residue out of the chamber and to compact the residue accumulated in a vertical column in the chamber to provide an effective seal against the diffusion and entry of air into the combustion area of the incinerator. Controls are provided in the sealing chamber to maintain the seal and to actuate the vibratory mechanisms for moving the residue. By the time the residue reaches the discharge of the chamber, the liquid in the residue is evaporated by the residual heat in the residue particles. The dried particles are thereafter transported by a transport conveyor from the outlet of the vibratory discharge conveyor to an appropriate point of disposal.
