Electromagnetically sustained plasma reactor

摘要

An improved plasma arc reactor is provided with variably positionable electrodes, including a cylindrical anode electrode having an inner, frustoconical cavity providing a reaction chamber and a spherical cathode ball electrode mounted therein. Between these electrodes an arc discharge is induced and sustained to heat and ionize an inert gas to produce an arc plasma for refining raw material introduced into the reaction chamber. A magnetic induction coil is mounted around the outer diameter of the anode electrode to thereby establish a magnetic field to rotate the arc discharge and plasma within the reaction chamber.
