Abstract:
Plasma arc stream generator, of closed configuration, comprising electrode chambers working in pairs, each pair having an anode and a cathode and being connected to a DC power source, the plasma jets having current passing through them, with spatial orientation by means of an external magnetic field directed such that the plasma jets from the chambers converge and form a common plasma stream with a central zone of uniform or lowered temperature, characterised in that the generator comprises at least three pairs of electrode chambers as above, and the said chambers are arranged in relation to each other such that the assembly is symmetrical without all the chambers being positioned in the same circle, and in that said generator further comprises one or more magnetic orientation devices (of the jets) outside all the electrode chambers, the generator creating a common plasma stream of closed configuration, elongated in shape with a central zone of uniform or lowered temperature in relation to the peripheral zone resulting from the convergence of at least six plasma jets.
