Title:

ELECTRIC ARC PLASMA TORCH

Document Type and Number:

WIPO Patent Application WO1995017278

Kind Code:

A3

Abstract:

The electric-arc plasma-steam torch has a housing accommodating coaxially arranged therein a nozzle anode and a cathode made fast in a holder. The housing communicates, via a pipe connector filled with a porous heat-conducting material, with a container. The container is filled with a moisture absorbent material which encompasses a tube running therethrough and made of a heat-conducting material. The tube has a flange at its end facing the nozzle anode. The flange is provided with passages on its end surface facing the nozzle anode. The aforementioned cathode holder is accommodated in the tube and is electrically insulated therefrom. A sleeve made of a heat-conducting material is interposed between the nozzle anode and the tube flange. The sleeve has passages on its outside cylindrical surface and on the surface contacting the nozzle anode. Steam resultant from the torch operation, is admitted, through the aforementioned passages, to the cathode and the nozzle anode, respectively, cools them and stabilizes the arc column by constricting the latter.
