Abstract
The invention relates to a liquid-cooled plasma burner, comprising a nozzle bore for the plasma gas jet to exit at a nozzle tip and a first section whose outer surface gradually tapers in the shape of a cone at an angle α in the direction of the nozzle tip, except for at least one deflection section that extends in the shape of a cone at an angle β in the direction of the nozzle tip. The invention also relates to an arrangement thereof with a nozzle cap and to a plasma burner comprising such an arrangement.
Claims25
A nozzle for a liquid-cooled plasma burner, comprising:
- a nozzle bore for a plasma gas jet to exit at a nozzle tip;
- a first section, the outer surface of said first section tapering in the shape of a cone in the direction of the nozzle tip at an angle α;
- and
- a plurality of deflection sections arranged on said outer surface, at least two of said deflection sections extending in the shape of a cone in the direction of the nozzle tip at angles β1, β2 to enhance cooling and coolant flow.
An arrangement, comprising:
- a nozzle having:
- a nozzle bore for a plasma gas jet to exit at a nozzle tip;
- and
- a first section, the outer surface of said first section tapering in the shape of a cone in the direction of the nozzle tip at an angle α, a plurality of deflection sections arranged on said outer surface, at least two of said deflection sections extending in the shape of a cone in the direction of the nozzle tip at angles β1, β2 to enhance cooling and coolant flow;
- a nozzle cap;
- and
- wherein the nozzle cap and the nozzle form a coolant chamber which is in fluid connection with a coolant supply line and a coolant return line, and wherein, at least in the region of the first section of the nozzle, the nozzle cap has an internal surface tapering in the shape of a cone in the direction of the nozzle tip.
