  • Plasma burner for transferred electric arc
    Patent number: 5206481
    Abstract: A plasma burner has an annular passage extending along an insulated tube defining the outer wall of the electrode lance and located between the electrode lance and the multi wall burner shell to deliver the auxiliary gas outwardly of the plasma gas. The nozzle forming end of the electrode lance has a coolant circulation as has the burner shell and the annular passage extends substantially to the coolant inlets and outlets of the burner. The construction avoids the formation of parasitic arcs.
