Abstract

A hydrogen torch comprising concentric inner and outer fluid delivery tubes wherein the outer tube comprises silica and the inner tube comprises silicon carbide. One end of the inner tube is connected to a third tube comprised of silica which has an inlet in fluid connection with a hydrogen supply line. The outer tube is in fluid connection with an oxygen supply line. A reverse ball joint connection is used to join the tubes and defines an annulus between the inner and outer tubes through which the oxygen can flow and be isolated from the hydrogen flowing within the inner tube.
