Description

Die Erfindung betrifft einen Reihenbrenner für ein gasbeheiztes Gerät gemäß den Oberbegriffen der nebengeordneten Ansprüche.The invention relates to a row burner for a gas-fired device according to the preambles of the independent claims.

Von derartigen Geräten ausgehend ist es Aufgabe vorliegender Erfindung, durch Gestaltung solcher Brenner und deren Elemente bei Änderung des Gas-Luft-Gemisches den Anteil der Stickoxide (NOx) in den Verbrennungsgasen zu senken.Starting from such devices, it is an object of the present invention to reduce the proportion of nitrogen oxides (NO x ) in the combustion gases by designing such burners and their elements when the gas-air mixture changes.

Erfindungsgemäß wird dies bei einem Reihenbrenner eingangs bezeichneten Gattung durch die kennzeichnenden Merkmale der nebengeordneten Ansprüche erreichtAccording to the invention, this is achieved in the case of a series burner at the beginning by the characterizing features of the independent claims

Man kann eine wünschenswerte Vervielfachung der Reihen von Brennöffnungen dadurch erzielen, daß man einen zwischen die beiden zueinandergehörigen Halbschalen eingefügten Einsatz vorsieht, der bereichsweise mit den Wandungen der Halbschalen verbunden, gemeinsam mit diesen Wandungen zwei seitlich verlaufende Reihen von Brennöffnungen begrenzt.A desirable multiplication of the rows of combustion openings can be achieved by providing an insert inserted between the two half shells that belong to one another, which is connected in some areas to the walls of the half shells, and together with these walls delimits two rows of combustion openings running laterally.

Gegebenenfalls können die bereichsweise miteinander verbundenen beiden Einsätze der beiden Halbschalen noch eine in der Symmetrieebene des Reihenbrenners verlaufende dritte Reihe von Brennöffnungen begrenzen. Ausführungsbeispiele erfindungsgemäßer Reihenbrenner werden nachstehend anhand der Zeichnungsfiguren erläutert:If necessary, the two inserts of the two half-shells, which are connected to one another in regions, can also delimit a third row of combustion openings running in the plane of symmetry of the row burner. Exemplary embodiments of row burners according to the invention are explained below with reference to the drawing figures:

Im wesentlichen umfaßt der dargestellte gasbeheizte Durchlaufwasserheizer eine isolierende Wandung 1, die eine Brennkammer 2 umschließt, oberhalb derer sich ein mit Rippen 3 versehener Wärmetauscher 4 befindetEssentially, the gas-heated water heater shown comprises an insulating wall 1 which encloses a combustion chamber 2, above which a heat exchanger 4 provided with ribs 3 is located

Unterhalb der Brennkammer 2 befindet sich zumindest ein Reihenbrenner 5, der eine Vielzahl von aus je zwei Halbschalen 14 zusammengesetzte Brennerkammem 20 aufweist deren Oberseiten eine Gasgemischverteilungskammer 6 mit Brennöffnungen 7 und 8 bilden und die mit bereichsweisen Einprägungen 9 in diese Gasgemischverteilungskammer 6 mündende vertikale Mischkanäle 10 einschließen, denen unterseitig einzelne der Gaszufuhr dienende, an einem Gaszufuhrrohr 11 ausgebildete Gasaustrittsdüsen 12 koaxial zugeordnet sind.Below the combustion chamber 2 there is at least one row burner 5, which has a multiplicity of burner chambers 20 composed of two half-shells 14 each, the upper sides of which form a gas mixture distribution chamber 6 with combustion openings 7 and 8 and which include vertical mixing channels 10 opening into this gas mixture distribution chamber 6 with area-shaped impressions 9 , on the underside of which individual gas supply nozzles 12, which are provided on a gas supply pipe 11 and are used for gas supply, are coaxially assigned.

Wie die Fig. 2 und 3 zeigen, sind unterhalb der gemeinsamen Brennkammer 2 des Gerätes fünf Brennerkammem 20 mit beispielsweise je drei Mischkanälen 10 vorgesehen.As shown in FIGS. 2 and 3, five burner chambers 20, each with, for example, three mixing channels 10, are provided below the common combustion chamber 2 of the device.

Die Fig. 4 und 5 zeigen die Gestaltung der oberen Bereiche eines solchen von den beiden Halbschalen 14 gebildeten Reihenbrenners 5, der - wie an sich bekannt - unterhalb der Gasgemischverteilungskammer 6 eine Einschnürung 15 aufweist.4 and 5 show the design of the upper regions of such a row burner 5 formed by the two half-shells 14, which - as is known per se - has a constriction 15 below the gas mixture distribution chamber 6.

Beim dargestellten Ausführungsbeispiel eines Reihenbrenners gehört zu jeder der beiden Halbschalen 14 je ein - aus Blech geformter - Einsatz 16, der - nur abschnittsweise - mit den Wandungen der Halbschalen 14 verbunden, gemeinsam mit diesen Wandungen zwei seitlich verlaufende Reihen 13 von Brennöffnungen 7 und 8 bildet, die einander abwechseln. Die größeren Brennöffnungen 7 weisen einen etwa rechteckigen lichten Querschnitt auf und sind die Haupt-Brennöffnungen, die kleineren Brennöffnungen 8 sind Hilfs-Brennöffnungen mit etwa kreisförmigem Querschnitt.In the illustrated embodiment of a row burner, each of the two half-shells 14 has an insert 16 formed from sheet metal, which - connected only in sections - to the walls of the half-shells 14, forms two laterally extending rows 13 of combustion openings 7 and 8 together with these walls that take turns. The larger firing openings 7 have an approximately rectangular clear cross section and are the main firing openings, the smaller firing openings 8 are auxiliary firing openings with an approximately circular cross section.

Die beiden nur bereichsweise miteinander verbundenen beiden Einsätze 16 begrenzen gemeinsam noch eine dritte, in der Symmetrieebene 17 des Reihenbrenners 5 verlaufende Reihe 13' von Haupt-Brennöffnungen 7 rechteckigen Querschnittes.The two inserts 16, which are only connected to one another in certain areas, jointly delimit a third row 13 'of main combustion openings 7 of rectangular cross section running in the plane of symmetry 17 of the row burner 5.

Alle diese Brennöffnungen 7 und 8 sind von bereichsweisen Einprägungen 9 bzw. 9' der Halbschalen 14 bzw. der Einsätze 16 begrenzt.All of these combustion openings 7 and 8 are delimited by area-specific impressions 9 and 9 'of the half-shells 14 and the inserts 16, respectively.

Während die Haupt-Brennöffnungen 7 über ihren gesamten Vertikalverlauf einen lichten Querschnitt konstanter Größe aufweisen, ist der lichte Querschnitt der Hiffs-Brennöffnungen B im unteren Bereich des Vertikalverlaufes geringer als im Mündungsbereich bzw. auch geringer als jener der Haupt-Brennöffnungen 7, so daß sich dort Haftflammen bilden.While the main combustion openings 7 have a clear cross section of constant size over their entire vertical course, the clear cross section of the Hiffs burn openings B is smaller in the lower region of the vertical course than in the mouth region or also less than that of the main combustion openings 7, so that form sticking flames there.

Die Einsätze 16 müssen im Rahmen der Erfindung selbstverständlich nicht unbedingt paarweise angeordnet werden, sondern sie können sich auch über die ganze Breite des Reihenbrenners erstrecken, also die Symmetrieebene 17 überbrücken und je zur Hälfte beidseits dieser Ebene 17 angeordnet sein.Of course, the inserts 16 do not necessarily have to be arranged in pairs within the scope of the invention, but they can also extend over the entire width of the row burner, that is to say bridge the plane of symmetry 17 and be arranged half on each side of this plane 17.

In dieem Fall mag es bedarfsweise auch ratsam sein, die Einsätze aus anderen hitzefesten Materialien auszubilden, z.B. aus keramischem Material. Es kann dann der einzelne Einsatz aus einer einzigen, mit Schlitzen und/oder Lochungen ausgebildeten massiven länglichen Platte bestehen, deren Längsränder satt an die Oberkanten der Halbschalen 14 anschließen.In this case, it may also be advisable, if necessary, to form the inserts from other heat-resistant materials, e.g. made of ceramic material. The individual insert can then consist of a single, solid, elongated plate formed with slots and / or perforations, the longitudinal edges of which closely fit the upper edges of the half-shells 14.

Aus den Figuren 6 und 7 geht ein weiteres Ausführungbeispiel eines Reihenbrenners hervor. Während beim Ausführungsbeipiel der Figuren 1 bis 5 ein Brenner mit stehenden Mischkanälen beschrieben wurde, ist bei dem Brenner nach dem Ausführungsbeispiel gemäß Figur 6 und 7 das Wesentliche eine Umlenkung 30, die zwischen den Mischkanälen 10 und der Gasluftgemisch-Verteilerkammer 6 vorgesehen ist. Die Umlenkung 30 muß sich nicht unbedingt am Ende sämtlicher Vormischkanäle 10 befinden, die Mischkanäle können sich auch nach dieser Umlenkung fortsetzung beziehungsweise die Umlenkung kann sich auch in der Gasgemisch-Verteilerkammer 6 befinden. Wesentlich ist auch bei diesem Ausführungsbeispiel, daß zwei oder mehr Mischkanäle in die gemeinsame Gasgemisch-Verteilerkammer 6 einblasen, womit ein hoher Primärluftanteil im Gasluftgemisch erzielbar ist. Verglichen mit einer Ausführungsform mit gegeneinander gerichteten Mischkanäten, die in eine gemeinsame Gasgemisch- Verteilerkammer einblasen, wird der Vorteil erheblich.geringerer Bautiefe erreicht, der nur mit einer geringfügigen Erhöhung der Bauhöhe kompensiert wird. Weiterhin ist hierzu nur ein einziges Gaszufuhrrohr erforderlich. Ist die bei dem Ausführungsbeispiel gemäß Figur 6 größere Höhe des Brenners nachteilig, so können die verschiedenen Mischkanäle auch nebeneinander in einer waagerechten Ebene angeordnet werden. Dann baut der Brenner allerdings breiter. Bevorzugt sind beim Ausführungsbeispiel der Figuren 6 und 7 die einzelnen einen Reihenbrenner bildenden Brennerkammern 20 aus jeweils zwei Blechteilen 14 gefertigt, die die Mischkanäle und die Gemischverteilerkammer als jeweils hälftige Einprägungen besitzen. Die beiden Blechteile 14 sind aneinandergelegt und längs ihres Umfangs gegebenenfalls auch im Mittenbereich miteinander verschweißt. Die Anfänge 31 der Mischkanäle können als aufgeweitete Öffnungen 32 gestaltet sein.A further exemplary embodiment of a row burner is shown in FIGS. 6 and 7. While a burner with standing mixing channels was described in the exemplary embodiment of FIGS. 1 to 5, the essential thing in the burner according to the exemplary embodiment according to FIGS. 6 and 7 is a deflection 30 which is provided between the mixing channels 10 and the gas-air mixture distribution chamber 6. The deflection 30 need not necessarily be at the end of all premixing channels 10, the mixing channels can continue after this deflection or the deflection can also be in the gas mixture distribution chamber 6. It is also essential in this exemplary embodiment that two or more mixing channels blow into the common gas mixture distribution chamber 6, with which a high proportion of primary air in the gas / air mixture can be achieved. Compared to an embodiment with mutually directed mixing channels that blow into a common gas mixture distribution chamber, the advantage is considerably greater. A lower overall depth is achieved, which is only compensated for by a slight increase in the overall height. Furthermore, only a single gas supply pipe is required for this. Is the greater height in the embodiment according to FIG. 6 disadvantage of the burner, the different mixing channels can also be arranged side by side in a horizontal plane. Then the burner builds wider. In the exemplary embodiment in FIGS. 6 and 7, the individual burner chambers 20 forming a row burner are each made of two sheet metal parts 14, which each have half the impressions of the mixing channels and the mixture distribution chamber. The two sheet metal parts 14 are placed against one another and welded to one another along their circumference, optionally also in the central region. The beginnings 31 of the mixing channels can be designed as widened openings 32.

Beim Ausführungsbeispiel gemäß Figur 8 ist der Reihenbrenner gemäß dem Ausführungsbeispiel nach Figur 6 und 7 weiter verbessert worden. Für den Fall, daß sich an den Mischkanalenden im Bereich der Umlenkung ungünstige Strömungsverhältnisse ergeben, sind die Umlenkungen alle an die Enden der einzelnen Mischkanäle verlegt Die Umlenkung erfolgt um jeweils 90°, ohne daß die Mischungsverhältnisse im einen Kanal Einfluß auf die des anderen Kanals haben. Die Austritte der Mischkanäle blasen alle gerade und gleichlinig in die Verteilerkammer ein. Ein etwaiges Rückprallen eines Gasstroms in einem Mischkanal hat keinen Einfluß auf die Gemischverteilung in einem anderen Kanal. Statt zwei Mischkanälen sind bei diesem Ausführungsbeispiel drei gewählt Die Mischkanäle nach dem Ausführungsbeispiel der Figur 8 liegen übereinander, sie können aber auch nebeneinander oder teitweise übereinander und nebeneinander liegen. Es ist möglich, die Umlenkung im obersten Mischkanal Ober einen größeren Winkel als 90° zu ziehen, falls man auf die Mischungsverhältnisse in dem Teil des Reihenbrenners verstärkt Rücksicht nehmen will, der dem Gaszuführungsrohr zugeordnet ist Es besteht auch die Möglichkeit, die Umlenkung der Mischkanäle, die dem dem Gaszufuhrrohr abgewandten Teil des Reihenbrenners zugeordnet sind, durch Verstärkung oder Rücknahme zu beeinflussen mit dem Ziel, daß der Gasluftgemisch-Austritt durch die Brennöffnugnen Ober die gesamte Längserstreckung des Reihenbrenners gieichmäßig wird.In the exemplary embodiment according to FIG. 8, the row burner according to the exemplary embodiment according to FIGS. 6 and 7 has been further improved. In the event that there are unfavorable flow conditions at the mixing channel ends in the area of the deflection, the deflections are all moved to the ends of the individual mixing channels. The deflection takes place by 90 ° in each case, without the mixing ratios in one channel having an influence on that of the other channel . The outlets of the mixing ducts all blow straight and straight into the distribution chamber. Any rebound of a gas flow in one mixing channel has no influence on the mixture distribution in another channel. Instead of two mixing channels, three are selected in this exemplary embodiment. The mixing channels according to the exemplary embodiment in FIG. 8 lie one above the other, but they can also lie side by side or partially one above the other and side by side. It is possible to pull the redirection in the uppermost mixing channel at a greater angle than 90 ° if you want to take greater account of the mixing ratios in the part of the in-line burner that is assigned to the gas supply pipe. It is also possible to redirect the mixing channels, which are assigned to that part of the in-line burner which faces away from the gas supply pipe, to be influenced by amplification or withdrawal with the aim that the gas-air mixture outlet through the combustion openings above the entire longitudinal extent of the in-line burner becomes the same.

Bei den Ausführungsbeispielen gemäß der Figuren 6 bis 8 bestehen die Reihenbrenner bevorzugt aus Blechschalen, dies kann, muß aber nicht so sein. Beispielsweise wäre auch eine Einformung der Verteilerkammer beziehungsweise der Mischkanäle in ein Druckgußteil mit hälftigen Schalen möglich.In the exemplary embodiments according to FIGS. 6 to 8, the row burners preferably consist of sheet metal shells, but this may or may not be the case. For example, the distribution chamber or the mixing channels could also be molded into a die-cast part with half shells.
