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. Ein solcher Brenner ist in der EP 0 235 789 A2 beschrieben.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 passages, 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. Such a burner is described in EP 0 235 789 A2.
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 Umständen 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 Invention is therefore to take measures by the noise produced is reduced significantly, 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, daß, 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 met by resonance conditional noise generation is fixed. A periodic Function is defined here like a curve with a Repeatedly occurring function value and course, transverse to 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 transverse 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 transverse to 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 inflow 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.

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

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

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

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

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%

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

durch die herkömmliche Verteilerplatte gebildet.4 shows an alternative implementation of the measures according to the invention. Here, the
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
