Abstract: The invention is a plasma torch for insertion through an opening in the wall of a waste processing chamber. The plasma torch of the invention is characterized by comprising a coaxial sleeve having an upper end and a lower end. The sleeve surrounds at least the portion of the outer surface of the torch that is located in the opening, thereby forming an insulating chamber between the outer surface if the torch and the inner surface of the sleeve. At least a portion of the portion of the coaxial sleeve that surrounds at least the portion of the outer surface of the torch that is located in the opening in the wall of the processing chamber is porous or permeable to a heat exchanging fluid. The torch comprises an inlet for introducing the heat exchanging fluid into the insulating chamber. When the plasma torch is inserted through the opening, a gap exists between the processing chamber wall and the coaxial sleeve.

Abstract: The invention is an apparatus and method for on-line sorting of waste matter, at the entrance to a waste processing plant, according to the level of specific chemicals, typically chlorine detected therein. The apparatus comprises a waste matter inlet that provides waste matter to a weighing module, preferably until a preset limit is reached. Then, this control volume of waste is introduced into a pulsed neutron material analyzer that is optimized for the determination of the content of the specific chemical in the control volume. A control means such as a computer then decides whether the level of the chemical in the waste control volume is above or below a preset threshold, and accordingly channels the waste into one or another of two channels. One of these channels accepts waste with low content of the given chemical, for introduction into the waste processing chamber.

Abstract: A liquid waste feeding system having a liquid inlet to a plasma torch based waste processing chamber, disposed intermediate the primary plasma torch arrangement at the bottom end of the chamber and the top gas products outlet. the liquid inlet is positioned within the chamber such that liquid waste flowing from the inlet into the chamber is directed at a high temperature zone of waste column, and the liquid inlet is typically associated with a hot gas jet means. The hot gas jet means that provides the required high temperature zone may comprise one or more secondary plasma torches configured to provide hot gas jets into the liquid discharge zone of the inlet. Alternatively, the hot gas jet may be provided by the primary plasma torches, in which case the liquid inlet is disposed within a predetermined area close to and above at least one of the primary plasma torches.
