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.
