摘要
A nozzle for the cutting beard removal where by means of additional heat supply the beard is liquified and blown away by the kinetic energy of a gas jet are formed by an upper and a lower nozzle plate with fuel gas discharge openings and an oxygen slot formed between them which is feeding an ever increasing quantity of oxygen at its longitudinal ends. This is reached by the oxygen slot forming the discharge end of a cone emerging from a distribution chamber enlarged in its longitudinal direction.
