ABSTRACT:
A transferred-arc plasma reactor is disclosed. The reactor comprises a bottom portion defining a crucible for collecting molten material, an anode adapted to contact the molten material in the crucible, a sleeve mounted on top of the crucible and electrically insulated therefrom, a cathode assembly including a cathode mounted on top of the sleeve and electrically insulated therefrom, means for introducing feed material conveyed by a carrier gas near the top of the sleeve so that the material is fed against the inner wall of the sleeve, melted under the heating energy radiated by a plasma arc formed between the cathode and the molten material to form a falling film of molten material which flows down along the inner wall of the sleeve and drops into the crucible underneath, and outlet ports in the bottom portion of the reactor for exiting the carrier gas and the non-reacted plasma forming gas.
