Definitions

  • the invention relates to a row burner for a gas-fired device according to the preambles of the independent claims.
  • a desirable multiplication of the rows of combustion openings can be achieved by providing an insert inserted between the two half shells that belong to one another, which is connected in some areas to the walls of the half shells, and together with these walls delimits two rows of combustion openings running laterally.
  • the two inserts of the two half-shells which are connected to one another in regions, can also delimit a third row of combustion openings running in the plane of symmetry of the row burner.
  • Exemplary embodiments of row burners according to the invention are explained below with reference to the drawing figures:
  • the gas-heated water heater shown comprises an insulating wall 1 which encloses a combustion chamber 2, above which a heat exchanger 4 provided with ribs 3 is located
  • At least one row burner 5 which has a multiplicity of burner chambers 20 composed of two half-shells 14 each, the upper sides of which form a gas mixture distribution chamber 6 with combustion openings 7 and 8 and which include vertical mixing channels 10 opening into this gas mixture distribution chamber 6 with area-shaped impressions 9 , on the underside of which individual gas supply nozzles 12, which are provided on a gas supply pipe 11 and are used for gas supply, are coaxially assigned.
  • five burner chambers 20, each with, for example, three mixing channels 10, are provided below the common combustion chamber 2 of the device.
  • each of the two half-shells 14 has an insert 16 formed from sheet metal, which - connected only in sections - to the walls of the half-shells 14, forms two laterally extending rows 13 of combustion openings 7 and 8 together with these walls that take turns.
  • the larger firing openings 7 have an approximately rectangular clear cross section and are the main firing openings, the smaller firing openings 8 are auxiliary firing openings with an approximately circular cross section.
  • combustion openings 7 and 8 are delimited by area-specific impressions 9 and 9 'of the half-shells 14 and the inserts 16, respectively.
  • the clear cross section of the Hiffs burn openings B is smaller in the lower region of the vertical course than in the mouth region or also less than that of the main combustion openings 7, so that form sticking flames there.
  • inserts 16 do not necessarily have to be arranged in pairs within the scope of the invention, but they can also extend over the entire width of the row burner, that is to say bridge the plane of symmetry 17 and be arranged half on each side of this plane 17.
  • inserts may also be advisable, if necessary, to form the inserts from other heat-resistant materials, e.g. made of ceramic material.
  • the individual insert can then consist of a single, solid, elongated plate formed with slots and / or perforations, the longitudinal edges of which closely fit the upper edges of the half-shells 14.
  • FIGS. 6 and 7 A further exemplary embodiment of a row burner is shown in FIGS. 6 and 7. While a burner with standing mixing channels was described in the exemplary embodiment of FIGS. 1 to 5, the essential thing in the burner according to the exemplary embodiment according to FIGS. 6 and 7 is a deflection 30 which is provided between the mixing channels 10 and the gas-air mixture distribution chamber 6.
  • the deflection 30 need not necessarily be at the end of all premixing channels 10, the mixing channels can continue after this deflection or the deflection can also be in the gas mixture distribution chamber 6. It is also essential in this exemplary embodiment that two or more mixing channels blow into the common gas mixture distribution chamber 6, with which a high proportion of primary air in the gas / air mixture can be achieved.
  • the advantage is considerably greater.
  • a lower overall depth is achieved, which is only compensated for by a slight increase in the overall height.
  • only a single gas supply pipe is required for this.
  • the different mixing channels can also be arranged side by side in a horizontal plane. Then the burner builds wider.
  • the individual burner chambers 20 forming a row burner are each made of two sheet metal parts 14, which each have half the impressions of the mixing channels and the mixture distribution chamber.
  • the two sheet metal parts 14 are placed against one another and welded to one another along their circumference, optionally also in the central region.
  • the beginnings 31 of the mixing channels can be designed as widened openings 32.
  • the row burner according to the exemplary embodiment according to FIGS. 6 and 7 has been further improved.
  • the deflections are all moved to the ends of the individual mixing channels.
  • the deflection takes place by 90 ° in each case, without the mixing ratios in one channel having an influence on that of the other channel .
  • the outlets of the mixing ducts all blow straight and straight into the distribution chamber. Any rebound of a gas flow in one mixing channel has no influence on the mixture distribution in another channel. Instead of two mixing channels, three are selected in this exemplary embodiment.
  • the row burners preferably consist of sheet metal shells, but this may or may not be the case.
  • the distribution chamber or the mixing channels could also be molded into a die-cast part with half shells.
