Definitions

  • the invention relates to an atmospheric gas burner according to the preambles of the independent claims.
  • Such a gas burner is known both from US-A-45 25 141, DE-U-8 507 804 and De-U-8 603 672, the latter utility model being in the priority interval.
  • solid rings serve as holders, which are pushed onto the burner tube and fastened thereon in such a way that they surround the burner tube properly.
  • Such rings naturally have to be manufactured or kept in stock for the respective tube diameter of the burner tube with an inner diameter resulting in a snug fit. If the burner tube needs maintenance or replacement, these rings must either be replaced or removed in a time-consuming process.
  • DE-U-8 603 672 shows an atmospheric gas burner which has cooling rods above a burner tube in the flame area and is mounted between its end holders depending on the length of the burner tube with one or more holders which are fixed or detachably fixed to the burner tube, wherein the holders are designed as a clamp.
  • Such a suitably designed sheet metal lamella takes up little space, can be fastened in areas of the burner tube which are free of mixture outlet openings and can be produced from comparatively thin sheet metal, which accordingly has a low thermal conductivity. Characterized in that such a sheet metal structure rests in places on the burner tube wall, it forms a solid holder, nevertheless it can be produced from easily processable material with little effort and expense.
  • such a holder can consist of a structure which at least in regions comprises at least one cooling rod and is preferably formed from a band.
  • a structure can encompass the cooling rod in a circumferentially closed manner and form a double-walled supporting web or diverging spreading supporting legs below the cooling rod.
  • such structures can also be applied in pairs in each case only to flank areas of cooling rods and can have diverging open holders formed above these flank areas.
  • brackets are fastenable to pipe clamps, the inside diameter of which corresponds to the outside diameter of the burner tube and which can be clamped onto this compliant burner tube.
  • FIGS. 1 to 6 first show burner tubes 1 with brackets 3 which serve for the storage of cooling rods 2, which form at least one cooling rod 2 at least in regions comprising loops and are formed from a strip or wire.
  • the band structure embodying the holder 3 according to FIG. 1 encompasses the cooling rods 2 entirely, that is to say in a closed manner, and forms double-walled supporting webs below the cooling rods.
  • such a holder 3 forms spread legs below the cooling rods 2 and in the embodiment according to FIG. 5 the band structure embodying the holder 3 only rests on the flanks of the cooling rods 2 and forms open, above these flank regions with divergent wings Insert the cooling rods 2 suitable recordings.
  • All of these band structures have angle legs, the curvature of which corresponds to that of the wall of the burner tube 1 and are attached to this wall so as to lie flat against this wall.
  • Figures 7 to 18 show embodiments of brackets 3, which are attached to pipe clamps 4, with which they enclose the wall of the cylindrical burner tube 1.
  • Such an annular pipe clamp 4 rests directly on the outside of the burner tube 1 and ends on its underside in two parallel legs 6, the bores 7 of which are aligned and leave a distance 5 apart and which can be pressed against one another by means of a bolt (not shown) around the pipe clamp 4 to be clamped to the burner tube wall.
  • the actual holder 3 is welded onto the top of this pipe clamp 4; it consists of a disk 8 with two support arms, which in turn bear flat, folded legs 9 on the burner tube wall. These two support arms delimit a recess 10 through which the flames of the burner can propagate from one side to the other of the holder 3 as soon as the burner is ignited.
  • the radii defined by the center points of the grooves 11 include central angles ⁇ of a size of approximately 27 °.
  • Figures 8 and 9 show sections VIII and IX, which are guided along the radii of the two outer grooves 11 and show that the holder 3 has fastening members in the form of bends 13 and 14 on its two lateral edges; one bend 13 has a hole 15, the other 14 has an undercut 16.
  • the end of a bracket 17 can be passed through the hole 15, the other end of which can be anchored in the undercut 16 and which holds the cooling rods 2 in the grooves 11 and presses them against the bottom of these tapering grooves 11, so that they are also held axially in it.
  • the associated second bracket 3 is shown in Figures 10 and 17; in terms of the organs used to attach it to the burner tube 1, it is the same as that shown in FIGS. 9 and 16.
  • the holder 3 of this pipe clamp 4 has three round holes 18 for mounting the cooling rods 2, in which they slide and are only held radially .
  • FIGS. 11 and 12 show cross sections of the holder 3 according to FIG. 10 in the planes XI-XI and XII-XII.
  • FIGS. 13 to 15 represent design variants, according to which the retaining rods 3 are formed with an oblique reinforcement and can be manufactured in one piece with the pipe clamp 4.
  • FIG. 18 shows a single burner tube 1 in plan view.
  • This burner tube 1 is closed on its end face 20 and a mixing tube 22 is provided at the opposite end 21, which opens into the burner tube 1 and into which a gas supply line 23 blows gas mixed with air via a gas nozzle 24.
  • Groups of holes and groups of slots are arranged alternately as mixture outlet openings 25.
  • the cooling rods 2 run such that they only cover areas of holes, but never areas of the slot groups. If 25 larger and smaller recesses of another figuration are provided as mixture outlet openings, then the cooling rods 2 are to be dimensioned and arranged such that they cover or overflow the round openings.
  • brackets 3 are provided, one of which is closer to the end face 20 according to FIG. 17, whereas the other according to FIG. 10 slides the cooling rods 2 by length changes due to different expansion coefficients of the material of the cooling rods 2 or the burner tube 1 to be able to compensate.
