Abstract (en)

[origin: WO9718692A1] A four-nozzle plasma generator comprising two anode electrode chambers and two cathode electrode chambers connected to DC power sources and generating four plasma jets of which the shape and the path are determined by an external magnetic field system. The plasma jets converge on a central area into which the material to be processed is injected, in order to form a single plasma stream. The nozzles are symmetrically arranged on a hood which includes a flat water-cooled diaphragm provided with a central aperture.
