Definitions

  • the invention relates to a gas surface burner for heating boilers according to the preamble of the main claim.
  • Such a gas surface burner is known from DE-A-35 03 553.
  • a short-burning surface flame standing in layers above the outflow surface can be generated, but it has been observed that particularly in the peripheral edge region of the poorly burning flame there are protruding, i.e. longer-burning flame regions, which also have negative effects on the measured NOX values to lead.
  • a further relevant prior art is represented by the following documents: US-A-1,582,634, DE-A-18 06 936 and DE-A-31 13416.
  • the invention is based on the object, starting from a gas surface burner of the type mentioned, to improve it in such a way that in the form of a surface flame directly behind the opening of the mixing chamber with a relatively low temperature and thus NOX-reducing burning gas-air mixture should also burn in the peripheral edge areas under these conditions.
  • this relatively simple measure of arranging a ring or frame-like edge cover can achieve that the peripheral edge regions burn largely in the manner of a surface flame, i.e. There are no protruding flame areas and the low NOX values to be achieved can be better achieved.
  • the mode of operation of such an edge cover it can initially only be assumed that a type of hot air or hot gas recirculation will presumably result in this area, whereby the recirculating hot gases also result in at least similar conditions for the edge areas of the surface flame as do those in the more inner areas the surface flame is present.
  • NOx reduction is also sought, but this is not a surface burner, but rather a burner tube which forms the end of an air-gas injector and is provided with an opening row on which a self-contained box is placed tightly and only has a slot arranged above the row of holes in the box lid.
  • a recirculation of hot gases from the combustion chamber is not given and possible, and the problem of stabilizing the edge flames of a surface burner does not exist with such a burner.
  • the gas supply connection on the box-shaped gas supply housing which is closed except for a necessary edge area with the burner plate, is arranged centrally for the most uniform gas supply distribution under the burner plate, the end of the mouth being provided with a closure plate provided with holes and openings arranged in the side wall of the end of the mouth are whose diameter is larger than that of the holes in the closure plate.
  • the requirement for equidistant spacing of the holes under the opening edge of the edge cover can be met most simply by arranging the holes in the burner plate in the form of a square grid, which, however, presupposes that the flame-retardant surface of the burner plate is also square and the outermost four rows of holes under the Edge of the corresponding square edge cover.
  • the holes of the burner plate must have a relatively small diameter, which is of the order of about 1 to 2.5 mm. In order to be able to make such smaller-diameter holes in the plate with as little effort as possible, only punching out is possible.
  • the burner plate must have a sufficient thickness in view of the temperature load in order to avoid warping of the plate. For this reason, the burner plate is formed from at least two spot-welded plate lamellae, the total thickness of which is greater than the diameter of the holes. This design of the burner plate means that its individual lamellae are accessible to a punching process for the attachment of the holes, which are then simply placed one on top of the other in alignment with the punched holes and spot welded the.
  • the burner plate is designed as a hollow body as a whole
  • this design ensures that every area of the burner plate, including the gas inflow channels, can be cooled.
  • This design also facilitates the manufacture of such a burner insofar as the hollow body can be easily assembled from two suitably perforated and pre-embossed shells, all of the assembly points, of course, having to be gastight and liquid-tight.
  • a practical embodiment of such a gas burning device can consist in that the gas inflow channels are designed in the form of inserted tubes which extend from one wall to the other wall of the hollow body. It is readily possible to arrange the tubes inserted into the hollow body in a gas- and liquid-tight manner, at least on the flame side, projecting beyond the wall of the hollow body in question.
  • ring-shaped, outward bends are expediently provided in the two hollow body walls, which can be easily formed when the respective shell is cut and pressed.
  • the gas inflow channels in the form of wall impressions on the gas supply-side hollow body wall and to connect the two walls of the hollow body around the gas outflow openings in a gas-tight and liquid-tight manner, which will be explained in more detail and where there is certainly the possibility of to establish the connection with a correspondingly dimensioned annular spot welding electrode around the respective outflow opening.
  • the embossed wall of the hollow body then represents itself similar to a waffle iron, whereby it must of course be ensured that the remaining cavity can be flowed through from the supply to the return connection.
  • it can advantageously also be ensured during the pressing process of the flame-side shell that ring-shaped offsets directed towards the flame side arise around the gas outflow openings.
  • the design principle of a coolable burner plate and its double-shell design also has the advantage of being able to dimension the sheet metal blanks larger and to keep the peripheral areas around free of gas outflow openings, the hole-free edges of the hollow body then being formed perpendicular to the burner plate surface to form a coolable peripheral wall limitation of the perforated burner plate .
  • a water-cooled shaft wall is thus created around and formed by the burner plate itself, which is also advantageous in terms of NOx reduction.
  • the aforementioned cover ring can be used here, but does not have to be provided.
  • This embodiment can also experience an advantageous further development in that one or the other wall of the hollow body, which extends perpendicular to the burner plate surface, is dimensioned longer than the other and in the protruding wall part, which is therefore no longer water-cooled, can flow through at least one gas, the free cross section heat exchanger approximately covering the burner plate at a distance above the burner plate and the short burner shaft together form a water-cooled element, so it is advantageously also easily possible to integrate a suitable heat exchanger without problems, for which the burner plate, which has been shaped into a pot, also forms the holder.
  • the gas surface burner consists of a mixing tube 14 provided with a blower connection with a central gas supply tube 13 which has perforations 16 in the area of the mixing tube 14 so that the gas can flow out there and with the air supplied by the blower rotor 15 can mix for which the mixing tube in the area of the blower housing 11 is provided with corresponding air inlet slots (not shown).
  • This mixing tube 14 is expediently arranged axially adjustable in the blower housing 11, which - as can be seen - is advantageously designed as a flat chamber 12.
  • the gas mixing tube 14 opens into a mixing chamber 5 which is relatively large in cross section and which is closed on the outflow side with a suitable perforated plate or a grating which forms the flame-effective surface 1.
  • the annular or frame-shaped edge cover 2 is arranged in its peripheral edge region, adapted to the cross-sectional shape of the surface, the opening cross section 3 of which corresponds to the flame-effective cross section of the surface 1. If it is a simple washer, this is of course fi at the desired distance by means of appropriate holding elements (not shown) xiert.
  • the edge cover on the fan side is provided with a circumferential web 4 which extends perpendicular to the plane of the edge cover 2.
  • a circumferential gap 6 can be provided between the mixing chamber 5 and the circumferential web 4, but care must be taken to ensure that recirculating hot gas 6 can flow into this circumferential gap, as indicated below with a dashed arrow.
  • the circumferential web 4 is advantageously provided with openings 7, so that hot gas can recirculate through these openings 7 from the combustion chamber 17 and then flow out again through the edge regions of the opening cross section 3 of the cover 2. This recirculating hot gas appears to create conditions for the edge areas of the flame which are automatically given for the flame areas located further inward, which are to a certain extent mutually supportive.
  • the circumferential web 4 is provided with a heat-insulating enclosure 8, for example made of ceramic fiber material or the like, which prevents heat radiation from the circumferential web 4.
  • the blower-side bottom 9 of the mixing chamber 5 is formed from heat-insulating material of the same type, this material being arranged directly on the blower housing 11, which forms a flat chamber 12 in which the blower rotor 15 with its motor 10 is eccentrically inserted Mixing chamber 5 leading mixing tube 14 is arranged.
  • the openings 7 can be more or less large and arranged in a more or less dense distribution on the circumferential web 4, which need not necessarily be circular holes as shown, but can also be slots or the like. Openings.
  • the swirl-imparting guide webs mediating the gas-air mixture can be arranged within the axially adjustable mixing tube, which then ensure a gas distribution in the mixing chamber 5 as a result of the swirl imparted in order to weaken a massive direct inflow of the central region of the surface 1.
  • the swirl-imparting guide webs mediating the gas-air mixture can be arranged within the axially adjustable mixing tube, which then ensure a gas distribution in the mixing chamber 5 as a result of the swirl imparted in order to weaken a massive direct inflow of the central region of the surface 1.
  • the surface burner consists of a box-shaped gas supply housing 212 with gas supply connection 27 and perforated burner plate 21 in association, as shown, wherein according to the embodiment, the gas supply housing 212 forms the lower part of a small heat exchanger arranged above it, which does not require any further explanation here.
  • the whole structure can practically be viewed as a small boiler.
  • the cross section of the gas supply housing 212 and thus also of the attached heating boiler is square according to the exemplary embodiment in FIG. 2, which is not binding, i.e. the whole could also have a circular cross section.
  • the annular or frame-shaped edge cover 22 is arranged over its edge regions, adapted to the cross-sectional shape of the burner plate 21, the opening cross section 23 of which corresponds to the flame-retardant surface of the perforated burner plate 21, ie the outermost holes 25 of the burner plate 21 are located under the opening edge 24 of the edge cover 22, which is provided with side openings 213 in the formation or profiling, for example, for the recirculation of hot gases from the area outside the edge cover professional.
  • the outer holes 25 of the burner plate 21 located under the opening edge 24 of the edge cover 22 are, as shown in FIG. 4, arranged at the same or approximately the same distance from one another, the hole density of the burner plate 21 in the region below the opening edge 24 being the same or approximately the same the hole density of the entire burner plate 21.
  • This arrangement and allocation of the holes 25 would be easiest to implement if the holes 25 of the burner plate 21 were arranged in the form of a square grid. If, in this case, the burner plate were punched out in a circle, the condition of equidistant spacing of the holes under the opening edge 24 and the requirement for approximately the same hole density in the edge region would no longer be met.
  • the mouth end of the gas supply connection 27 is arranged centrally under the burner plate, the mouth end 26 being provided with a closure plate 29 provided with holes 28 (FIG. 3), with openings 211 around the side wall 210 of the mouth end 26 are arranged, the diameter of which is larger than that of the holes 28 in the closure plate. If these lateral openings 211 were not present, there would be a preferred flow against the center area of the burner plate 21, which would, however, prevent the formation of a surface-burning flame.
  • the burner plate 21 is formed from at least two spot-welded plate lamellae 21 ', the total thickness of which is greater than the through Knife of the holes 25.
  • the thickness of the two plate lamellae 21 ' is 2.5 mm and can therefore still be punched with respect to the holes 25 if they also have a diameter of 2.5 mm, for example. Due to the aligned joining and spot welding of the two plate fins 21 ', the burner plate 21 is then sufficiently stable against thermal distortions.
  • 0.5 to 4 gas mixture passage openings are preferably provided per cm 2 of burner area.
  • the burner also consists of a gas supply housing 318 with a gas connection 319 and with a multiplicity of gas outflow openings which are arranged uniformly distributed in a coolable burner plate 31 which closes the housing 318.
  • the burner plate 31 is designed as a hollow body 32 and is provided with supply and return connections 33, 34, the gas inflow channels 36 leading to the gas outflow openings 35 of the plate 31 being arranged in the hollow body 32, the walls of which 37 separate the interior of the hollow body 32 from the channels 36, which means nothing else that all areas of the burner plate 31 are directly accessible from the cooling medium.
  • the gas inflow channels 36 are designed in the form of gas and liquid-tight tubes 38, which extend from one wall 32 'to the other wall 32 "of the hollow body 32 and, in a preferred embodiment, at least on the flame side via the wall 32' of the hollow body 32.
  • the tubes 38 are, as can be seen from the sectional area in FIG. 1, enclosed in annular, outwardly directed crimps 310 of the two hollow body walls 32 ', 32 ".
  • FIG. 5 is preferred, in which the hollow body is formed from two shells and that of the gas outflow openings 35 kept free edges 312 of the hollow body 32 to form a coolable peripheral wall 313 of the perforated burner plate 31 perpendicular to the burner plate surface 314.
  • the entire burner plate is shaped into a pot-like structure, the side walls of which can also be cooled directly in the area of the flame front.
  • Corresponding embossments 320 in the region of the coolable peripheral boundary wall 313 serve to stiffen the entire pot.
  • the wall 32 ′ of the hollow body 32 extending perpendicular to the Benner plate surface 314 is also longer than the other.
  • the resulting and protruding wall part 315 can be used as a holder for a gas-flowable, the free cross section approximately covering the burner plate 31 covering heat exchanger 316, which is arranged at a suitable distance above the burner plate 31.
  • the hollow body 32 is expediently connected on the return side to the flow connection 317 of the heat exchanger 316, so that there is a continuous flow for the cooling medium for the whole, namely from the burner plate connection to the heat exchanger flow.
  • the burner plate or the gas mixture outflow openings on the gas mixture inflow side are covered with a fine-meshed grille 41, which once equalizes the mixture inflow to the openings and in particular counteracts the risk of flashback in the mixture inflow chamber under the burner plate.
  • the arrangement of such a grid 41 or single-mesh screen can also be used in the embodiments according to FIGS. 5 to 7.
