Abstract (en)

[origin: US4594496A] A plasma burner for introducing an ionizable gas stream into an electric arc comprises a nozzle having an outlet opening for discharging the gas stream. The outlet opening is defined by an outlet part of the nozzle; the outlet part has an inner nozzle face conically tapering, at an acute first cone angle, in a direction of the outlet opening. The plasma burner further has an electrode surrounded by the outlet part and having an outer electrode face conically tapering, at an acute second cone angle, in the direction of the outlet opening. The inner nozzle face and the outer electrode face together define a conical annular channel.
