Definitions

  • the invention relates to an atmospheric premixed gas burner arrangement having a burner plate which closes a burner chamber which is connected via at least one mixing tube to an injector inlet which is supplied with gas.
  • the mixing tubes are designed as separate parts which, on the one hand, are connected to the burner plate, which is likewise designed as an individual part, with an injector inlet, likewise formed as an individual part.
  • the aim of the invention is to avoid these disadvantages and to propose a premix gas burner arrangement of the type mentioned at the outset which can be produced simply and with little assembly effort.
  • the mixing tube is formed by a mixing tube section formed from the bottom of the burner plate and by a mixing tube section formed from the injector inlet Mixing tube section is formed, which are both inserted into one another.
  • the entire premix gas burner arrangement can be produced from only two parts, which can be easily connected to one another.
  • this results in a very short length of the sealing edges compared to the known solutions, in which sealing edges result on both sides of the mixing tubes.
  • the mixing tube section formed from the bottom of the burner plate is formed into a sleeve at its free end.
  • the two parts of the premix gas burner arrangement can be assembled particularly easily by further aids.
  • a gas distribution tube is arranged along each row of mixing tubes.
  • the bottom of the burner plate is provided with circumferential upstanding walls, which is provided in its upper regions with a circumferential formation, one with circumferential walls, which is shaped substantially in the opposite direction to the walls of the floor and on the walls of the bottom can be snapped on.
  • the burner plate can be manufactured very easily.
  • the premix gas burner arrangement 1 has an atmospheric gas burner and a burner plate 2, which, as can be seen from FIG. Outlet openings 16 are provided for a gas-air mixture, which are designed as slots 17 and bores 18.
  • the lid 5 also has circumferential side walls 6 which protrude downward and overlap the side walls 4.
  • the side walls 4 are provided in their upper end region with a convex shape 7 projecting outwards.
  • the side walls 6 of the cover 5 are provided with a circumferential bead 8 which is formed essentially opposite to the shape 7. This bead 8 is adjoined by an outwardly bent region 9, which makes it easier to put the cover 5 on.
  • Mixing tube sections 10 are formed, for example, by deep drawing, from the bottom 3 of the burner plate 2 made from deep-drawn sheet metal, as can be seen from FIG. 2, which shows the burner plate 2 with the cover 5 lifted off.
  • the mixing tube sections 10 are essentially trumpet-shaped and have a molded sleeve 11 at their free end.
  • a trumpet-shaped mixing tube sections are likewise formed from a substantially U-shaped injector inlet 12 arranged essentially parallel to the burner plate 2 13 deep-drawn, the ends of which are inserted into the sleeves 11.
  • gas distribution pipes 14 are arranged which are equipped with gas nozzles 21 which are aligned coaxially with the mixing pipe sections 13 which are arranged in rows 22 and columns 23.
  • a water-conducting cooling coil 15 is arranged above the burner plate 2.
