Definitions

  • the invention relates to a focal surface perforation according to the preamble of claim 1.
  • a fuel gas-air mixture is generated in fuel rods from atmospheric gas burners, that escapes through a perforation on the surface and burns there.
  • Breakthroughs create individual flames that are more or less from the burning surface take off.
  • W- or V-shaped ones are formed Flames, the outer wings of which move up and down. This leads to noise, whereby the noises of the equally frequented flames become relatively high Can add up noise levels.
  • the invention has for its object to provide a focal surface perforation excellent burning behavior combined with extremely strong noise reduction.
  • the focal surface perforation according to the invention has those mentioned in claim 1 Characteristics.
  • Fuel rods with parallel columns of slots are generally known. In doing so then 2 or 3 columns along the fuel rod axis next to each other.
  • she Slot rows consist of a multitude of long, narrow slots, the width of which must be less than 1 mm for safety reasons. 0.6-0.8 are common mm.
  • a maximum of 10 times the slot width has been found to be a suitable slot length. If you set the slot width at 0.7 to 0.8 mm, that would be a length of less than 8 mm. In particular, the middle web between the columns should be as possible be narrow. A convenient measure is a width of approximately the web width between the Slots, which should be about 7 times the slot width. At a The slot width of 0.7 to 0.8 mm would then be about 0.5 to 0.6 mm.
  • the width of the two outer intermediate webs between the columns also has an influence on the burning behavior and the noise level, but also on the stability of the fuel rod. It is recommended that the width of these two outer intermediate webs about 2 to 4 times, preferably 2.5 to 3 times, the width of the middle intermediate web is.
  • the slot width a is specified for safety reasons. It must be less than 1 mm, preferably between 0.6 and 0.8 mm.
  • the slot length b is at most 10 times the slot width a.
  • the web width c between the slots 3 and also the width of the middle intermediate web 5 between the columns 2 about 0.7 times the slot width a.
  • the width of the outer intermediate webs 6 between the columns 2 is preferably 2.5 to 3 times the width of the central intermediate web 5.
  • the continuous slots 7 have the slot width a and one lateral limiting dimension of the columns 2 on both sides by more than 1 mm Length.
