Abstract

The main burner body (2) has an upstream inflow surface (4), and a downstream outflow surface (6), with passages (8) between the two surfaces. At least some of the openings (8'a,8'b) of the ducts (8) and situated in the inflow surface are spaced apart by unequal distances (d1,d2) in relation to the upstream, perforated reference plane (18). The distance-variations between the openings and the reference plane perform at least a periodic function in a direction across the flow direction of the gas mixture.

Description

Die Erfindung bezieht sich auf einen Brenner für gasförmige Brennstoffe, umfassend einen aus zumindestens einem plattenförmigen Teil bestehenden Brennerkörper mit einer in Strömungsrichtung des Gas-Luftgemisches stromaufwärtsen Anströmoberfläche, einer stromabwärtsen Ausflußoberfläche und zwischen ihnen verlaufenden Durchlaßkanälen, wobei von wenigstens einer Anzahl der in der Anströmoberfläche liegenden Mündungen der Durchlaßkanäle die jeweiligen Distanzen zu einer stromaufwärts davon liegenden perforierten Bezugsebene ungleich sind.The invention relates to a burner for gaseous Fuels comprising one from at least one plate-shaped part existing burner body with a Flow direction of the gas-air mixture upstream Inflow surface, a downstream outflow surface and between them passing through channels, of at least a number of those in the inflow surface lying mouths of the passage channels the respective Distances to an upstream thereof perforated reference plane are unequal.

Deratige Brenner sind an sich bekannt aus EP-A-0 602 831. Bei einem derartigen Brenner besteht der Brennerkörper meistens aus einem hitzebeständigen keramischen Material. Eine Anzahl der in EP-A-0 602 831 gezeigten Brennerkörper ist einfach gekrümmt.Such burners are known per se from EP-A-0 602 831. In such a burner there is the burner body mostly made of a heat-resistant ceramic material. A number of the torch bodies shown in EP-A-0 602 831 is simply curved.

Gasbrenner können beim Betrieb, unter bestimmten Umstanden insbesondere ein Resonanzgeräusch hervorbringen, das als störend empfunden wird. Um so mehr weil in der Praxis mehr und mehr moderne, sehr kompakte Hochleistungskessel nicht mehr in einen speziellen, abgeschlossenen Raum untergebracht werden, sondern dort aufgestellt werden, wo dies im Zusammenhang mit der Nutzung des vorhandenen Raumes so günstig wie möglich ist, sollte angestrebt werden, dieses Geräusch soviel wie möglich einzudämmen. Aufgabe der Erfindung ist es daher, Maßnahmen zu ergreifen, durch die das hervorgebrachte Geräusch sehr erheblich verringert, wenn nicht ganz eliminiert wird.Gas burners can operate, under certain circumstances in particular produce a resonance sound, which as is perceived as disturbing. All the more because in practice more and no more modern, very compact high-performance boilers more housed in a special, enclosed space be placed where it is in the Connection with the use of the available space as cheap as possible, should be aimed at this Curb noise as much as possible. Task of The invention is therefore to take measures by the noise produced is greatly reduced, if is not entirely eliminated.

Ausgehend von dem Gedanken, daß das hervorgebrachte Geräusch im wesentlichen von Resonanzen verursacht wird, hat Anmelderin gefunden, daß deren nahezu völlige oder sogar völlige Unterdrückung mit den Maßnahmen von Anspruch 1 erreicht wird. Überraschenderweise hat sich herausgestellt, daR, wenn diese Maßnahme erfüllt wird, die durch Resonanzen bedingte Geräuscherzeugung behoben wird. Eine periodische Funktion ist hier definiert wie eine Kurve mit einem wiederholt auftretenden Funktionswert und Verlauf, quer zur Gasgemischströmungsrichtung gesehen.Based on the thought that the sound produced is essentially caused by resonances Applicant found that its almost complete or even total suppression with the measures of claim 1 is achieved. Surprisingly, it turned out that if this measure is taken, the resonance conditional noise generation is fixed. A periodic Function is defined here like a curve with a Repeatedly occurring function value and course, across the Gas mixture flow direction seen.

Vorzugsweise erfüllt die Distanzvariation in einer Dimension des Brennerkörpers quer zu der Gasgemischströmungsrichtung zumindestens eine Periode der periodischen Funktion, die vorzugsweise eine Sinusfunktion ist. Auch eine Variation gemäß mehreren Funktionen ist möglich.The distance variation preferably fulfills in one dimension of the burner body transversely to the gas mixture flow direction at least one period of the periodic function, the is preferably a sine function. Another variation according to several functions is possible.

In einer bevorzugten Ausbildung wird ein Brennerkörper mit einer flachen Anströmoberfläche angewendet, und ist die Bezugsebene eine perforierte Platte, die in einer Dimension quer zu der Gasgemischströmungsrichtung wellenförmig verläuft. Jedoch ist auch eine Ausführungsform möglich, bei der die Bezugsebene eine im wesentlichen flache, perforierte Platte ist, während die Anströmoberfläche des Brennerkörpers in einer Dimension quer zu der Strömungsrichtung des brennbaren Gas-Luftgemisches wellenförmig verläuft. Diese flache Platte kann die herkömmliche Verteilerplatte sein.In a preferred embodiment, a burner body is used a flat inflow surface, and is the Reference plane is a perforated plate that is in one dimension wavy across the gas mixture flow direction runs. However, an embodiment is also possible which the reference plane is a substantially flat, perforated Plate is while the upstream surface of the burner body in a dimension transverse to the flow direction of the flammable gas-air mixture is undulating. This flat plate can be the conventional distribution plate.

Das Schutzbegehren erstreckt sich weiter auf einen in den Ansprüchen 7 und 8 definierten Gasbrenner.The request for protection extends to one in the Claims 7 and 8 defined gas burners.

Der in dieser Beschreibung und in den Ansprüchen verwendete Ausdruck "plattenförmig" impliziert nicht, daß die zwei Hauptdimensionen des Querschnitts des Brennerkörpers in einer flachen Ebene liegen.The one used in this description and in the claims The expression "plate-shaped" does not imply that the two Main dimensions of the cross section of the burner body in lie on a flat plane.

Die Figuren zeigen eine Ausbildung, in der der Brennerkörper im wesentlichen plattenförmig ist; jedoch ist auch eine Konfiguration möglich, in der der Brennerkörper im Schnitt kreisförmig of C-förmig ist, oder aber eine weitere Konfiguration aufweist.The figures show a design in which the burner body is substantially plate-shaped; however is also one Configuration possible in which the torch body in the cut is circular or C-shaped, or another Configuration.

Die Fig. 1 zeigt im Längsschnitt und schematisch einen Teil eines plattenförmigen Brennerkörpers 2 mit einer Anströmoberfläche 4, und einer Ausflußoberfläche 6 mit zwischen ihnen Kanälen 8, die in Anströmrichtung 10 eines brennbaren Gas-Luftgemisches, das über eine stromaufwärts des Brennerkörpers 2 angeordnete Verteilerplatte 12 mit Perforationen 14 anströmt, verlaufen. Beim Betrieb bilden sich Flammen 16 an der Seite der Ausflußoberfläche 6. Ein derartiger Aufbau mit Brennerkörper 2 und Verteilerplatte 10 ist an sich bekannt und hat die im Obenerwähnten beschriebenen Nachteile.Fig. 1 shows in longitudinal section and schematically a part a plate-shaped burner body 2 with a Inflow surface 4, and an outflow surface 6 with between them channels 8, the one in the flow direction 10 combustible gas-air mixture that has an upstream the burner body 2 arranged distributor plate 12 with Perforations 14 flow, run. Form during operation there are flames 16 on the side of the discharge surface 6. a such a structure with burner body 2 and distributor plate 10 is known per se and has the above mentioned disadvantages described.

Zur Realisierung des erfindungsgemäßen Vorschlags ist gemäß Fig. 1 stromaufwärts der Anströmoberfläche 4 eine in eine einzige Richtung gewellte, perforierte Platte 18 angeordnet, die die in den Ansprüchen genannte Bezugsebene bildet. So ist also für zum Beispiel den Durchlaßkanaal 8a die Distanz dessen Mündung 8'a, mit d1 angedeutet, unterschiedlich von der Distanz d2 zwischen der Mündung 8'b dieser Fläche. Die Wellungen in der Platte verlaufen nach einer Sinusfunktion; ihre Nullinie ist mit 20, die Periode mit P und die Spitze-Spitze-Amplitude mit A angedeutet. Werte für diese, für eine praktische Ausbildung gewählten Größen, werden am Ende dieser Beschreibung gegeben.1, a perforated plate 18 corrugated in a single direction is arranged upstream of the inflow surface 4, which forms the reference plane mentioned in the claims. Thus, for example, for the passage channel 8a, the distance of its mouth 8'a, indicated by d 1 , is different from the distance d 2 between the mouth 8'b of this surface. The corrugations in the plate follow a sine function; its zero line is indicated by 20, the period by P and the peak-to-peak amplitude by A. Values for these sizes chosen for practical training are given at the end of this description.

Es sei bemerkt, daß es zum Erreichen der bezweckten Wirkung nicht wesentlich ist, ob die Verteilerplatte 12 vorhanden oder nicht vorhanden ist.It should be noted that it is intended to achieve the intended effect it is not essential whether the distributor plate 12 is present or does not exist.

Die Fig. 2 zeigt in Perspektive, wie die erfindungsgemäßen Maßnahmen in der Praxis auf einfache Weise realisiert werden können. Der Brennerkörper 2 ist in einem Gehäuse 22 angeordnet; die Ausflußoberfläche des Brennerkörpers 2 bildet die Oberfläche dieses Gehäuses. In dieser Ausbildung wird die Unterseite des Gehäuses durch die Platte 12 gebildet, und eine gewellte, perforierte Metallplatte 24, die die Bezugsebene 18 in Fig. 1 bildet, ist zwischen Brennerkörper 2 und Verteilerplatte 12 angeordnet. Diese gewellte Platte 24 kann aber auch, wie einleuchtend sein wird, die Unterseite des Gehäuses bilden, wobei die Platte 12 dann entfällt.Fig. 2 shows in perspective how the invention Measures can be implemented in practice in a simple manner can. The burner body 2 is in a housing 22 arranged; the outflow surface of the burner body 2 forms the surface of this housing. In this training the bottom of the housing is covered by the plate 12 formed, and a corrugated, perforated metal plate 24, which forms the reference plane 18 in Fig. 1 is between Burner body 2 and distributor plate 12 arranged. This corrugated plate 24 can also be as obvious will form the bottom of the case, the plate 12 is then omitted.

Die Figur 3 zeigt, wie die erfindungsgemäß vorgeschlagenen Maßnahmen ohne weitgehende Modifikationen in einer bereits bestehenden Konstruktion realisiert werden. Mehr insbesondere zeigt Fig. 3 ein Detail eines von Anmelderin hergestellten und auf den Markt gebrachten Heizkessels vom Typ "Ecomline". Bei diesem Kessel wird das brennbare Gas-Luftgemisch über den Zuführstutzen 30 zugeführt und strömt dann in Richtung auf den Pfeil 32 zu der Brennereinheit 34, mit, in Strömungsrichtung 32 gesehen, nacheinander der Verteilerplatte 36 (vergleichbar mit der Verteilerplatte 12 in Fig. 2) und dem perforierten keramischen Brennerkörper 38 (vergleichbar mit dem Brennerkörper 6 in Fig 2, beziehungsweise 1).Figure 3 shows how the proposed according to the invention Measures without extensive modifications in one already existing construction can be realized. More in particular, Figure 3 shows a detail of one made by the applicant Manufactured and placed on the market from Type "Ecomline". In this boiler, the combustible gas-air mixture fed through the feed pipe 30 and flows then in the direction of arrow 32 to the burner unit 34, with, viewed in the direction of flow 32, one after the other Distribution plate 36 (comparable to distribution plate 12 in FIG. 2) and the perforated ceramic burner body 38 (comparable to the burner body 6 in FIG. 2, or 1).

Wie sich aus den Figuren ergibt, kann die erfindungsgemäß vorgeschlagene, gewellte und perforierte Platte 40 ohne nennenswerte Änderung der Konstruktion zwischen der Verteilerplatte 36 und dem Brennerkörper 38 angeordnet werden; die Praxis hat gezeigt, daß diese an sich sehr einfache Maßnahme zu einer überraschenden und erheblichen Abnahme des vom Brenner beim Betrieb hervorgebrachten Geräusches führt. Die einfache Befestigung des Brenners 34 an der Kesselkonstruktion 42 unter Einfügung der Dichtungsprofile 44 macht den Brenner 34 gut zugänglich.As can be seen from the figures, according to the invention proposed, corrugated and perforated plate 40 without significant change in construction between the Distributor plate 36 and the burner body 38 are arranged will; practice has shown that this in itself is very simple measure to a surprising and substantial Acceptance of that produced by the burner during operation Noise leads. Easy attachment of the burner 34 on the boiler structure 42 with the insertion of the Sealing profiles 44 make the burner 34 easily accessible.

In einer in der Praxis geprüften Ausbildung hat die Brennerplatte 38 die folgenden Abmessungen: Länge x Breite = 226 x 90 mm; und hat die perforierte, gewellte Platte 40 die Abmessungen Länge x Breite = 235 x 92 mm; die in Fig. 2 abgebildeten Wellungen stehen quer zu der Längsrichtung, haben eine Periodizität von 36 mm (also insgesamt 6 ganze Wellungen über die Längsrichtung) mit einer Spitze-Spitze-Amplitude von 6 mm. Der Perforationsgrad der Verteilerplatte 36 betrug 4% und derjenige der perforierten Platte 40, 50% bei einem im wesentlichen regelmäßigen Perforationsmuster.In a course tested in practice, the Burner plate 38 the following dimensions: length x width = 226 x 90 mm; and has the perforated corrugated plate 40 die Dimensions length x width = 235 x 92 mm; that in Fig. 2 shown corrugations are transverse to the longitudinal direction, have a periodicity of 36 mm (a total of 6 whole Longitudinal corrugations) with a peak-to-peak amplitude of 6 mm. The degree of perforation of the distribution plate 36 was 4% and that of the perforated plate was 40.50% with a substantially regular perforation pattern.

Die Fig. 4 zeigt eine alternative Realisierung der erfindungsgemäßen Maßnahmen. Hier ist die Ausflußoberfläche 52 des Brennerkörpers 50 eine flache Ebene, und ist die Anströmoberfläche 54 in einer Richtung quer zu der Anströmrichtung des brennbaren Gas-Luftgemisches gewellt ausgeführt, wodurch auch hier als Effekt erzielt wird, daß die jeweiligen Distanzen der Mündungen der angrenzenden Durchlaßkanäle 58, die zwischen Anströmoberfläche 54 und Ausflußoberfläche 52 verlaufen, unterschiedlich sind. Die Distanz ist für den Kanal 58a mit d3 und für den Kanal 58b mit d4 angegeben. Die perforierte Bezugsebene 60 wird hier durch die herkömmliche Verteilerplatte gebildet.4 shows an alternative implementation of the measures according to the invention. Here, the outflow surface 52 of the burner body 50 is a flat plane, and the inflow surface 54 is designed to be corrugated in a direction transverse to the inflow direction of the combustible gas-air mixture, which also has the effect here that the respective distances of the mouths of the adjacent through-channels 58 which run between the inflow surface 54 and the outflow surface 52 are different. The distance is given for channel 58a with d 3 and for channel 58b with d 4 . The perforated reference plane 60 is here formed by the conventional distributor plate.

Der Vorteil dieser Konstruktion besteht darin, daß die zusätzliche Zwischenplatte entfallen kann, jedoch steht dem gegenüber, daß der Brennerkörper 50, wie die Zeichnung zeigt, stellenweise ziemlich dünn sein wird.The advantage of this construction is that the additional intermediate plate can be omitted, but that is opposite that the burner body 50 as the drawing shows will be pretty thin in places.
