Abstract (en)
[origin: EP0017201A1] 1. Direct current plasma torch comprising a bar-shaped cathode and an anode symmetrical with respect to rotataion and disposed concentrically to said cathode and an annular clearance between cathode and anode for introducing the gas to be heated, the cathode having at its free end an annular edge and the free end of the cathode being located in an axially parallel magnetic field constant in time, while a magnetic field constant in time but diverging in the direction of flow exists in the area located downstream of the free end of the cathode such that the plasma arc forming between cathode and anode is caused to rotate, characterized in that the cathode (5) has a continuous inner bore (6), through which part of the gas to be heated is introduced into the plasma torch at such a velocity of flow that the point at which the plasma arc connects to the cathode is localized at the annular edge (7) of the cathode (5).
