Abstract

Burner plate 1 of an atmospheric gas burner fed with a fuel/air mixture, mixture outlet orifices 3 passing through the said burner plate which has an irregular shape in order to avoid resonant vibrations during operations. Such an irregular shape lies, within the scope of the invention, in the design of the mixture outlet orifices 3, at least some of which are surrounded by edge regions 4 projecting from the plane of the burner plate. <IMAGE>

AT396819B Die Erfindung betrifft eine von Gemischaustrittsöffhungen durchsetzte Brennerplatte eines mit einem Brennstoff-Luft-Gemisch gespeisten atmosphärischen Brenners, die zur Vermeidung betrieblicher Resonanzschwingung«! eine unregelmäßige Gestaltung aufweist. Es hat sich gezeigt, daß eine regelmäßig gestaltete, d. h. Symmetrien aufweisende, Brennerplatte, insbesondere dann, wenn sie einer vergleichsweise kleinen Brennerkammer zugeordnet ist, dazu neigt, im Betrieb gemeinsam mit den Wandungen der Brennerkammer störende Resonanzgeräusche, insbesondere Pfeiftöne, zu verursach«!. Die Resonanz ergibt sich dadurch, daß die Wandungen der Brennerkamm«' als starr anzusehen sind und einander parallel gegenfiberliegen; vor allem gilt dies für die Brennerplatte und dem ihr gegenüberliegenden Boden der Brennerkammer. Aus der FR-OS 2 538 082 ist eine unregelmäßig gestaltete Brennerplatte mit unregelmäßig angeordneten Gemischaustrittsöffnungen bekanntgeworden. Diese Gestaltung wurde jedoch gewählt, um einen Kamineffekt zu simulieren. Außerdem ist die Herstellung einer solchen Brennerplatte sehr schwierig. Aufgabe der Erfindung ist es, ein« Resonanzwirkung auf einfache Weise wirkungsvoll vorzubeugen und die akustisch störenden Eigenschwingungen der Brennerplatte zu verhindern. Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die unregelmäßige Gestaltung der aus Blech bestehenden Brennerplatte in der Ausbildung von ungleichartigen Gemischaustrittsöffnungen besteht, wobei zumindest ein Teil der Gemischaustrittsöffnungen von aus der Brennerplattenebene auskragenden Randbereichen umschlossen ist Eine Ausführungsform einer erfindungsgemäß gestalteten Brennerplatte ist in der Zeichnungsfigur in einem Vertikalschnitt veranschaulicht Die Brenneiplatte (1) wird in Richtung der Pfeile (2) von einem Brennstoff-Luft-Gemisch durchströmt und weist zu diesem Zweck Gemischaustrittsöffnungen (3) auf, die das Innere der nicht dargestellten Brennerkammer mit der Atmosphäre verbinden und im Flammenbereich des Brenners münden. Gemäß der Ausführungsform ist ein Teil der Gemischaustrittsöffnungen (3) von profiliert«! Randbereichen umschlossen, die als Krägen (4) ausgebildet sind. Eine solche ungleiche, unregelmäßige Profilierung der Ränder der Gemischaustrittsöffnungen (3) führt bereits wirksam zur Verringerung der Resonanz. PATENTANSPRUCH Von Gemischaustrittsöffnungen durchsetzte Brennerplatte eines mit einem Brennstoff-Luft-Gemisch gespeisten atmosphärischen Gasbrenners, die zur Vermeidung betrieblicher Resonanzschwingungen eine unregelmäßige Gestaltung aufweist, dadurch gekennzeichnet, daß die unregelmäßige Gestaltung der aus Blech bestehenden Brennerplatte (1) in der Ausbildung von ungleichartigen Gemischaustrittsöffnungen (3) besteht, wobei zumindest ein Teil der Gemischaustrittsöffnungen (3) γοη aus der Brenneiplattenebene auskragenden Randbereichen (4) umschlossen ist. Hiezu 1 Blatt Zeichnung -2-AT396819B The invention relates to a burner plate of an atmospheric burner fed with a mixture of fuel outlet and air and which to avoid operational resonance oscillation. has an irregular design. It has been shown that a regularly designed, i.e. H. Burner plate having symmetries, especially if it is assigned to a comparatively small burner chamber, tends to cause disturbing resonance noises, in particular whistling tones, together with the walls of the burner chamber during operation. The resonance results from the fact that the walls of the burner comb are rigid and lie opposite one another in parallel; This applies above all to the burner plate and the bottom of the burner chamber opposite it. From FR-OS 2 538 082 an irregularly designed burner plate with irregularly arranged mixture outlet openings has become known. However, this design was chosen to simulate a chimney effect. In addition, the manufacture of such a burner plate is very difficult. The object of the invention is to effectively prevent a resonance effect in a simple manner and to prevent the acoustically disturbing natural vibrations of the burner plate. According to the invention, this object is achieved in that the irregular design of the burner plate made of sheet metal consists in the formation of dissimilar mixture outlet openings, at least some of the mixture outlet openings being surrounded by edge regions projecting from the burner plate plane Vertical section illustrated The fuel plate (1) is flowed through in the direction of the arrows (2) by a fuel-air mixture and for this purpose has mixture outlet openings (3) which connect the interior of the burner chamber, not shown, with the atmosphere and in the flame area of the burner flow out. According to the embodiment, part of the mixture outlet openings (3) is profiled by! Enclosed edge areas which are designed as collars (4). Such an uneven, irregular profile of the edges of the mixture outlet openings (3) already effectively leads to a reduction in the resonance. PATENT CLAIM Burner plate of an atmospheric gas burner fed with a mixture of fuel and air, which has an irregular design to avoid operational resonance vibrations, characterized in that the irregular design of the burner plate (1) made of sheet metal in the formation of uneven mixture outlet openings (3 ), whereby at least a part of the mixture outlet openings (3) γοη from the Brenneiplattenplane projecting edge regions (4) is enclosed.
