Definitions

  • the front end of the outer tube of the nozzle is generally provided with a surface and skirt, protruding beyond from the front end of the inner tube of the nozzle.
  • the diameter and the depth of the skirted surface must have a defined ratio which is a function of the diameter of the supply gas inlet channel and the pressure of the fluid in circulation.
  • the insulating member (5) which is essential to limit the location of the formation of sparks only at the end of the nozzle, as indicated above, is suitably arranged so as to cause the formation of sparks before the outlet of the gas mixture. As a result, the structure is simple and convenient to make.
  • the inner tube (1) and the outer tube (3) are both made of copper. We pass a mixture of propane and oxygen from preheating in an annular passage channel (4) provided between the tubes (1) and (3).
  • the electrical insulating member (5) is made of ceramic.
  • the inner surface (10) of the insulating member (5) faces a part of the channel (4) constituted by several grooves (14) formed by machining on the outer periphery of the inner tube (1), and in the direction of the axis of said tube (1).
  • the grooves (14) are arranged at equal intervals on the periphery of the tube (1).
