PLASMABRENNER

This invention is related to a new plasma burner comprising an electrode holder for the support of a centrally arranged and an outer electrode, means for applying an electrical voltage for producing an electric arc between the electrodes, and means for the supply of gas to the electric arc area of the electrode. The plasma burner is characterised in that the electrodes constitute a continuously consumable electrode system consisting of an inner, pipe or rod-shaped electrode (1) which is arranged coaxially in an outer, pipe-shaped electrode (11), so that between the electrodes there is formed a passage of annular cross-section, and in that the electrode holder (2, 3; 12, 13) is designed to conduct gas through the passage between the electrodes (1, 11) forwards to a front, free end of the electrodes where the electric discharge occurs from the end of the inner electrode.
