1. A system for generation of a high temperature gas stream comprising:

  • a. a plasma generator unit having a housing, an arcing chamber inside the housing, first, second and third stationary primary electrodes spaced circumferentially around the inside of the housing to define an arcing region between the electrodes within the arcing chamber, and an opening at one end of the housing for exhausting the gas stream;

    b. power supply means to connect each of the first, second, and third electrodes to a separate phase of a three-phase alternating current supply voltage;

    c. oscillator means to inject an ionized oscillator gas into the arcing region;

    d. working gas supply means to deliver a working gas into the chamber; and

    e. control unit means to control the plasma generator unit, the power supply means, the oscillator means, and the working gas supply means.
