Definitions

  • the invention relates to an atmospheric gas burner or the like via a mixing tube. from a gas nozzle arranged at a distance from the inlet of this mixing tube and fed with a gas-primary air mixture burner chamber.
  • the air ratio of the mixture that is to say the proportion of the combustion air in the mixture, must have an optimal size.
  • the problem therefore arises of keeping the actual air content of the mixture, which is influenced by various parameters, including the gas pressure at the gas nozzle, at its level, although the local conditions can be different.
  • the volume flow of the mixture can only be reduced by precisely adapting the primary air ratio to the prevailing local conditions, e.g. gas type, gas pressure and the like, in order to stabilize the flames.
  • the object of the invention is to enable such an exact adaptation of the primary air ratio to the given local conditions in a simple manner, namely by retrofitting gas burners manufactured in series at their installation site.
  • Another object of the invention is to provide components for such gas burners that enable such retrofitting without any significant assembly effort.
  • the design of the stem of the mixing tube is assigned a stem which, if necessary, determines the size of the primary air portion.
  • a stem can be made for certain predetermined local conditions and can easily be installed in a desired position in the area of the inlet of the mixing tube.
  • Such a stem can be fastened to the gas nozzle holder connecting the gas nozzle to the mixing tube, the desired position of the cover already resulting from the manner in which it is fastened without further action.
  • the cover on the Gas nozzle holder can be pushed on or plugged on and held positively in this desired position.
  • this can be achieved very simply in that the gas nozzle is held on the mixing tube by means of an angular holder, one angle leg of which supports the gas nozzle and the other leg of which is attached to the outside of the mixing tube, around the gas nozzle at a desired distance from the inlet distance of the mixing tube.
  • the cover can also be made very simple and robust, namely, for example, consist of a U-profile, the web on which the gas nozzle connects with the inlet of the mixing tube leg of the holder lies flat and whose two legs between the gas nozzle and the Limit the space of the mixing tube inlet on both sides.
  • the U-profile of the cover e.g. by means of extensions of its two legs projecting inwards against each other on both sides, form a guide for the leg of the angular holder resting against its web.
  • a cover designed as a rectangular or square profiled sleeve with two flanges can overlap the leg of the angular holder resting on the mixing tube and thus results in an easy to manufacture and reliable form-fitting connection.
  • an end wall can also be provided which attaches to the bottom of the cover and engages under the gas nozzle with a recess.
  • the cover can also be fastened to the end of the mixing tube forming the inlet, in which case it expediently consists of a sleeve which can be plugged onto the free end of the mixing tube and which is axially displaceable and adjustable into its desired position is, it only has to extend over a part of the circumference of the mixing tube to facilitate its attachment.
  • the size of the primary air portion flowing to the gas-air mixture can also be varied very delicately and set to an optimal target value such that recesses penetrate the wall of the cover.
  • recesses can be used for the regulation of the primary air portion in the sense of the invention, but also their shape.
  • round, preferably circular, rectangular or square and / or triangular recesses can advantageously be provided.
  • a gas nozzle (not shown) is attached coaxially to the angle leg 3 of an angular holder 5, the other angle leg 4 of which is attached to the outside of the cylinder wall along a generatrix of the cylindrical wall of the mixing tube 1, at a predetermined desired distance x. e.g. is welded on.
  • this gas nozzle holder which is manufactured as standard, are matched to a specific gas pressure and only result in an optimal air ratio at this gas pressure, i.e. an optimal ratio of the gas and primary air components in the gas-air mixture.
  • the primary air supply must be throttled in the space between the gas nozzle and the mixing tube inlet.
  • a cover 5 suitable for this consists, according to a first embodiment, of a U-profile, the web 6 of which rests flat on the angle leg 4 connecting the gas nozzle to the mixing tube 1 and the two legs 7 on both sides of which limit and cover the space between the gas nozzle and the mixing tube inlet .
  • the shape of the cover 5 is also matched to the holder 2 of the gas nozzle 9 on the mixing tube 1, namely this cover 5 consists of a sheet metal bent to form a sleeve with an approximately square profile, the upper side of which is only two mutually facing flanges 10 are formed, with which this cover 5 rests on the top of the leg 4 attached to the mixing tube 1 of the holder 2.
  • These flanges 10 hold the cover 5, which consists of a base 11 and the two side walls 12, on the angle leg 4.
  • this cover 5 has an end wall 13, which engages under the gas nozzle 9 with a recess 14 and thereby centers the cover 5 with respect to the axis of the mixing tube 1.
  • the side walls 12 of the cover 5 can be penetrated by recesses 15 of any design, the shape and size or number of which can be used to regulate the extent of the primary air flowing into the gas stream.
  • a cover 5 consists of a circular profiled sleeve, the inside diameter of which corresponds approximately to the outside diameter of the mixing tube 1 adjoining the front side of a burner chamber 16, but which extends only over part of the circumference of the mixing tube and e.g. is resilient, can be attached to the mixing tube 1.
  • This sleeve-shaped cover 5 is axially displaceable within the distance x with respect to the gas nozzle 9 and the mixing tube 1 and its respective optimal position can be determined empirically.
  • Figures 10 to 15 show various options for the design of recesses 15, which can be provided in the wall of a cover to allow the most optimal possible adjustment of the optimal primary air content, with the shape of these recesses 15 targeted to the displaceability of the cover 5 can be considered with respect to the wall of the mixing tube 1.
  • This cover 5 is mounted either by axially sliding it onto the free end of the mixing tube 1 or by clamping the resilient sleeve in a direction perpendicular to the axis of the mixing tube 1
  • this cover 5 can be adjusted by axial displacement such that the size of the remaining Distance from the gas nozzle 9 or by the shape, size and number of the areas of the recesses 15 of the wall of the cover 5 which remain open in each case, the supply of the correct proportion of primary air is ensured.
  • FIG. 10 shows, for example, four circular recesses 15 in the cover wall
  • FIG. 11 shows two circular recesses 15 of larger diameter
  • FIG. 12 shows two longitudinal slots 15, the course of which has the consequence that the primary air inflow changes continuously, linearly when the cover 5 is displaced this inflow can be changed progressively according to a third-order function when a triangular recess 15 according to FIG. 13 is arranged.
  • FIGS. 14 and 15 show embodiments with a large number of relatively small recesses 15, which can be formed in any desired systematic arrangement in the wall of the cover 5.
