Description

Die Erfindung bezieht sich auf einen atmosphärischen Gas­brenner mit wenigstens einem langgestreckten, innerhalb einer Brennkammer angeordneten Brennerrohr, dessen Wandung an ihrer Oberseite Gemischaustrittsöffnungen für ein dem Brennerrohr zugeführtes Gas-Luft-Gemisch aufweist, wobei diesem, vorzugsweise metallenen, Brennerrohr zumindest eine Halterung für zumindest einen, vorzugsweise aus keramischem Material bestehenden, im wesentlichen zur Achse des Brenner­rohres parallelen, in einem Abstand von der Rohrwandung ver­laufenden Kühlstab zugeordnet ist.The invention relates to an atmospheric gas burner with at least one elongated burner tube arranged within a combustion chamber, the wall of which has mixture outlet openings on its top for a gas-air mixture supplied to the burner tube, this, preferably metal, burner tube having at least one holder for at least one , preferably made of ceramic material, essentially parallel to the axis of the burner tube and extending at a distance from the tube wall.

Ein solcher Gasbrenner ist aus US-A- 4 525 141 und aus der DE-U- 8 507 804 bekannt. Bei dem aus der USA-A vorbekannten Gasbrenner dienen als Halterungen massive Ringe, die auf das Brennerrohr aufgeschoben und daran derart befestigt werden müssen, daß sie das Brennerrohr satt umschließen. Solche Ringe müssen naturgemäß für den jeweiligen Rohr­durchmesser des Brennerrohres mit einem einen Paßsitz ergebenden Innendurchmesser gefertigt bzw. auf Lager gehalten werden. Bedarf das Brennerrohr einer Wartung oder eines Austausches, müssen diese Ringe entweder mitausgetauscht oder zeitaufwendig abgenommen werden. Durch den Paßsitz dieser massiven Ringe ergibt sich auch eine unerwünscht gute Wärme­leitung zwischen dem zu kühlenden Brennerrohr und den zu seiner Kühlung bestimmten Kühlstäben, so daß ein Teil der von letzteren im Flammenbereich zweckdienlich aufgenommenen Hitze nicht abgeleitet, sondern in das Brennerrohr einge­leitet wird.Such a gas burner is known from US-A-4,525,141 and from DE-U-8,507,804. In the gas burner previously known from the USA-A, massive rings serve as holders, which have to be pushed onto the burner tube and fastened to it 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. The fit of these massive rings also results in an undesirably good heat conduction between the burner tube to be cooled and the cooling rods intended for cooling it, so that part of the heat expediently absorbed by the latter in the flame area is not dissipated, but rather is introduced into the burner tube.

Bei den aus der DE-U vorbekannten Gasbrennern dienen als Halterung von Kühlstäben U-förmig abgekantete Bleche, die sich mit einem Steg quer über das Brennerrohr erstrecken und mit zwei senkrechten Schenkeln an den Brennerrohrflanken tangierend befestigt sind. Durch diese Art der Befestigung wird aber die Wandung des Brennerrohres örtlich erheblich geschwächt und diese Befestigung, die außerdem höhenver­stellbar sein soll, kann allzuleicht örtliche Schäden in dieser thermisch hochbeanspruchten Wandung verursachen und bildet diesbezüglich eine ständige Gefahrenquelle, zumal sich durch die Brennertemperaturen verursachte unterschied­lich thermisch bedingte Formänderungen zwangsläufig speziell in diesem Wandungsbereich ungünstig auswirken müssen.In the gas burners known from DE-U serve as a holder for cooling rods U-shaped folded sheets which extend across the burner tube with a web and are tangentially attached to the burner tube flanks with two vertical legs. With this type of fastening, however, the wall of the burner tube is considerably weakened locally and this fastening, which should also be adjustable in height, can all too easily cause local damage in this thermally highly stressed wall and forms a constant source of danger in this regard, especially since the burner temperatures cause different thermal conditions Changes in shape must inevitably have an adverse effect, especially in this wall area.

Erfindungsgemäß werden die oben geschilderten Nachteile der vorbekannten Halterungen bei einem Gasbrenner der eingangs bezeichneten Gattung dadurch vermieden, daß der Kühlstab, vorzugsweise eine Gruppe solcher Kühlstäbe gemeinsam, von zumindest einer an der Außenseite der Wandung des Brennerrohres bereichsweise aufliegend befestigten, als Halterung ausgebildeten Blechlamelle gehalten ist.According to the invention, the above-described disadvantages of the known holders in a gas burner of the type mentioned at the outset are avoided in that the cooling rod, preferably a group of such cooling rods together, is held as a holder by at least one sheet metal lamella which is attached to the outside of the wall of the burner tube .

Eine solche geeignet gestaltete Blechlamelle beansprucht wenig Raum, kann in Bereichen des Brennerrohres befestigt werden, die frei von Gemischaustrittsöffnungen sind und ist aus vergleichsweise dünnem Blech herstellbar, das dem­entsprechend eine geringe Wärmeleitfähigkeit besitzt. Dadurch, daß ein solches Blechgebilde bereichsweise satt auf der Brennerrohrwandung aufliegt, bildet es eine solide Halterung gleichwohl es mit geringem Arbeits- und Kosten­aufwand aus einfach verarbeitbaren Material herstellbar ist.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 lies on the burner tube wall in some areas, it forms a solid holder, nevertheless it can be produced from easily processable material with little effort and expense.

Für eine zweckdienliche Gestaltung der Halterung stehen im Rahmen der Erfindung vorteilhafterweise mannigfaltige Möglichkeiten offen.Various possibilities are advantageously available within the scope of the invention for an expedient design of the holder.

So kann eine solche Halterung erfindungsgemäß aus einem zumindest einen Kühlstab zumindest bereichsweise umfassenden, vorzugsweise aus einem Band geformten Gebilde bestehen. Ein solches Gebilde kann den Kühlstab umfanggeschlossen umfassen und unterhalb des Kühlstabes einen doppelwandigen Tragsteg oder divergierend gespreizte Tragbeine bilden. Man kann aber auch solche Gebilde in paarweiser Anordnung jeweils nur an Flankenbereichen von Kühlstäben anliegen und oberhalb dieser Flankenbereiche divergierend offene Halterungen bilden lassen.Thus, according to the invention, such a holder can consist of a structure which comprises at least one cooling rod, at least in regions, preferably formed from a band. Such 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. However, 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.

Ferner ist es im Rahmen der Erfindung auch möglich, die Halterungen an Rohrschellen zu befestigen, deren lichter Durchmesser dem Außendurchmesser des Brennerrohres ent­spricht und die an diesem konformen Brennerrohr anklemmbar sind.Furthermore, it is also possible within the scope of the invention to fasten the brackets to pipe clamps, the clear diameter of which corresponds to the outer diameter of the burner tube and which can be clamped onto this conforming burner tube.

Weitere Erfindungsmerkmale solcher Rohrschellen sind nach­stehend erläutert und bilden die Gegenstände von Unter­ansprüchen.Further features of the invention of such pipe clamps are explained below and form the subject of subclaims.

Die Figuren 1 bis 6 zeigen zunächst Brennerrohre 1 mit zur Lagerung von Kühlstäben 2 dienenden Halterungen 3, die zumindest einen Kühlstab 2 zumindest bereichsweise umfassen­de Schlaufen bilden und aus einem Band oder Draht geformt sind.FIGS. 1 to 6 first show burner tubes 1 with brackets 3 used 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.

Das die Halterung 3 verkörpernde Bandgebilde nach Figur 1 umfaßt die Kühlstäbe 2 zur Gänze, also umfanggeschlossen und bildet unterhalb der Kühlstäbe doppelwandige Tragstege.The band structure embodying the holder 3 according to FIG. 1 comprises the cooling rods 2 in its entirety, that is to say in a closed manner, and forms double-walled supporting webs below the cooling rods.

Gemäß der Ausführungsform nach Figur 3 bildet eine solche Halterung 3 unterhalb der Kühlstäbe 2 gespreizte Standbeine und bei der Ausführungsform nach Figur 5 liegt das die Halterung 3 verkörpernde Bandgebilde nur an den Flanken der Kühlstäbe 2 an und bildet oberhalb dieser Flanken­bereiche mit divergierenden Flügeln offene, zum Einfügen der Kühlstäbe 2 geeignete Aufnahmen.According to the embodiment according to FIG. 3, 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.

Alle diese Bandgebilde besitzen Winkelschenkel, deren Krümmung jener der Wandung des Brennerrohres 1 entspricht und sind mittels dieser Winkelschenkel an dieser Wandung flächig anliegend befestigt.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.

Die Figuren 7 bis 18 zeigen Ausführungsformen von Halterungen 3, die an Rohrschellen 4 befestigt sind, mit denen sie die Wandung des zylindrischen Brennerrohres 1 umschließen. Eine solche ringförmige Rohrschelle 4 liegt unmittelbar an der Außenseite des Brennerrohres 1 an und endet an ihrer Unterseite in zwei unter Belassung eines Abstandes 5 einander parallel gegenüberliegenden Schenkeln 6, deren Bohrungen 7 fluchten und die mittels eines nicht dargestellten Bolzens gegeneinander preßbar sind, um die Rohrschelle 4 an der Brennerrohrwandung auzuklemmen.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 legs 6, parallel to each other while leaving a distance 5, the bores 7 of which are aligned and which can be pressed against one another by means of a bolt (not shown) around the pipe clamp 4 on the burner tube wall.

Auf der Oberseite dieser Rohrschelle 4 ist die eigentliche Halterung 3 aufgeschweißt; sie besteht aus einer Scheibe 8 mit zwei Tragarmen, die ihrerseits an der Brennerrohrwandung flächig anliegende, abgekantete Schenkel 9 tragen. Diese beiden Tragarme begrenzen eine Ausnehmung 10, durch die sich die Flammen des Brenners von einer zur anderen Seite der Halterung 3 fortpflanzen können, sobald der Brenner gezündet wird.The actual holder 3 is welded onto the top of this pipe clamp 4; it consists of a disc 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.

Gemäß Figur 7 und 10 sind im oberen Rand der Scheibe 8 der Halterung 3 drei sich abwärts verjüngende Nuten 11 angeordnet, deren Mittelpunkte auf einem Teilkreis 12 liegen, der zur Achse 13 des Brennerrohres 1 konzentrisch ist. Dadurch sind die Kühlstäbe 2 durchwegs gleich weit von der Brennerrohrwandung entfernt.According to FIGS. 7 and 10, three downwardly tapering grooves 11 are arranged in the upper edge of the disk 8 of the holder 3, the center points of which lie on a pitch circle 12 which is concentric with the axis 13 of the burner tube 1. As a result, the cooling rods 2 are equally far away from the burner tube wall.

Die von den Mittelpunkten der Nuten 11 definierten Radien schließen Zentriwinkel α einer Größe von etwa 27° ein.The radii defined by the center points of the grooves 11 include central angles α of a size of approximately 27 °.

Die Figuren 8 und 9 zeigen Schnitte VIII und IX, die entlang der Radien der beiden äußeren Nuten 11 geführt sind und zeigen, daß die Halterung 3 an ihren beiden seitlichen Rändern Befestigungsorgane in Form von Abwinkelungen 13 bzw. 14 aufweist; die eine Abwinkelung 13 besitzt ein Loch 15, die andere 14 eine Hinterschneidung 16.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.

Gemäß Figur 16 kann durch das Loch 15 das Ende eines Bügels 17 geführt werden, dessen anderes Ende sich in der Hinter­schneidung 16 verankern läßt und der die Kühlstäbe 2 in den Nuten 11 festhält und sie gegen den Boden dieser sich ver­jüngenden Nuten 11 preßt, so daß sie darin auch axial fest­gehalten werden.According to Figure 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.

Die zugehörige zweite Halterung 3 ist in den Figuren 10 und 17 dargestellt; sie ist hinsichtlich der zu ihrer Be­festigung am Brennerrohr 1 dienenden Organe gleich jener nach den Figuren 9 und 16. Die Halterung 3 dieser Rohrschelle 4 weist jedoch drei runde Löcher 18 zur Lagerung der Kühl­stäbe 2 auf, in denen diese gleitend lagern und nur radial gehalten sind.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. However, 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 .

Die Figuren 11 und 12 zeigen Querschnitte der Halterung 3 gemäß Figur 10 in den Ebenen XI-XI und XII-XII. Die Figuren 13 bis 15 stellen Ausführungsvarianten dar, denen­zufolge die Halterunen 3 mit einer Schrägversteifung ausge= bildet und mit der Rohrschelle 4 einstückig gefertigt sein können.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 stiffening and can be manufactured in one piece with the pipe clamp 4.

Die Anordnung der Rohrschellen 4 am Brennerrohr 1 ist in der Figur 18 dargestellt, die ein einzelnes Brennerrohr 1 in Draufsicht zeigt. Dieses Brennerrohr 1 ist an seiner Stirn­seite 20 geschlossen und am gegenüberliegenden Ende 21 ist ein Mischrohr 22 vorgesehen, das in das Brennerrohr 1 mündet und in das eine Gaszufuhrleitung 23 über eine Gasdüse 24 mit Luft vermischtes Gas einbläst.The arrangement of the pipe clamps 4 on the burner tube 1 is shown in FIG. 18, which 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.

Als Gemischaustrittsöffnungen 25 sind Gruppen von Löchern und Gruppen von Schlitzen alternierend angeordnet. Die Kühl­stäbe 2 verlaufen derart, daß sie nur Bereiche von Löchern abdecken, aber nie Bereiche der Schlitzgruppen. Sind als Gemischaustrittsöfnungen25 größere und kleinere Ausnehmungen anderer Figuration vorgesehen, dann sind die Kühlstäbe 2 so zu bemessen und anzuordnen, daß sie jeweils die runden Öffnungen abdecken bzw. überlaufen.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 larger and smaller recesses of another figuration are provided as mixture outlet openings 25, then the cooling rods 2 are to be dimensioned and arranged such that they cover or overflow each of the round openings.

Aus der Figur 18 ist auch ersichtlich, daß jeweils zweierlei Halterungen 3 vorgesehen sind, von denen die der Stirnseite 20 nähere nach Figur 17 ausgebildet ist, wogegen die andere nach Figur 10 die Kühlstäbe 2 gleitend lagert, um Längen­änderungen infolge unterschiedlicher Ausdehnungskoeffizienten des Materiales der Kühlstäbe 2 bzw. des Brennerrohres 1 aus­gleichen zu können.From FIG. 18 it can also be seen that two types of 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.
