Definitions

  • the measure described in claim 3 also ensures that an inner secondary bend, which may overlap the inner wall part of the nozzle, cannot reach the outer wall part of the nozzle via the nozzle or jacket holder.
  • the second insulating section according to claims 3 and 4 is also advantageous that they are arranged at a "cold" point of the burner and can therefore be made of a less heat-resistant insulation material.
  • the insulation rings each represent part of the inner surface of the wall parts of the nozzle, so that these are also cooled by the cooling liquid.
  • the self-contained insulating coating is omitted from the insulating ring 17d according to FIG. 6.
  • This ring has only two metallic layers 38 ', 38 "which are mechanically held together by an insulating layer 39' formed from a sealing compound.
  • the insulating ring 17d formed in this way is overall more scratch-resistant and can be sealed well against the wall parts 13 'and 13" of the nozzle 5 .
  • a second insulating ring 18a is provided, which is stepped in a Z-shaped cross section.
  • the insulating ring 18a has an external thread 54 which is offset towards the center and which engages with a corresponding internal thread 55 in the rear section 11 ".
  • the insulating ring 18a has an external thread 54 which is offset towards the center and which engages with a corresponding internal thread 55 in the rear section 11 ".
  • a recessed cylindrical part 56 which fits into a corresponding recess 57 in the rear Section 11 "engages.
  • the cylindrical connection 56/57 is sealed by an O-ring 58.
  • At the opposite end of the second insulating ring 18a there is an extension starting from the inner surface 60 with an internal thread 62 which is in engagement with a corresponding external thread 63 of the front section 11 ′ of the inner wall part 11.
