ABSTRACT:
The present invention is a decontamination plant for removing contaminates from contaminated material. The decontamination plant comprises an outer shell including a cavity therein. A drum formed of heat conductive material is rotatably mounted in the cavity defined by the outer shell so as to form an annular heating chamber between the drum and the outer shell. A plurality of heat sources are positioned to discharge heat into the annular heating chamber. The drum also has an inner surface defining a decontamination chamber. A tube is concentrically supported within the decontamination chamber formed in the drum. The tube has an inlet which is in communication with the annular heating chamber so as to receive flue gases therefrom. The outlet of the tube is positioned to exhaust gases from the drum. The drum is slightly inclined from a material receiving opening to a soil discharge end so as to cause the material which is being decontaminated to progress through the decontamination chamber as the drum rotates. While the material is passing through the decontamination chamber, the material is held in contact with the heating drum and the heated tube so as to heat the material via conduction.
