Abstract (en)
[origin: EP0743811A1] The DC arc plasma torch has first and second electrodes (1,2) formed as coaxial tubes on either side of a chamber (3) into which the gas to be decomposed is injected. The electrodes are open at the ends facing the injection chamber. Electrical connections allow application of direct current to the electrodes to establish an arc discharge between them. One of the electrodes is open at its outer end (6) to allow flow of the plasma (13) generated by the arc beyond the end of the electrode. Provision is made to inject air through holes (7,8) round the periphery of the outer end of the electrode to form a fluid layer separating the plasma from the wall of the electrode.
