Description

Hintergrung der ErfindungBackground of the Invention

Die Erfindung betrifft einen Gebläsebrenner mit einem mit einem ersten Lochmuster versehenen, zur Flammenseite hin ausgewölbten Brennerblech und einem damit korrespondierenden mit einem zweiten Lochmuster versehenen, mit dem Brennerblech formschlüssig verbundenen und unter ihm angeordneten Verteilerblech, das außerdem randseitig mit einem dessen Ränder umfassenden Brennergehäuse verbunden ist.The invention relates to a forced draft burner with a a first hole pattern, towards the flame side bulging burner plate and a corresponding one with a second hole pattern, with the Burner plate positively connected and under it arranged distributor plate, which also with connected to a burner housing comprising its edges is.

Stand der TechnikState of the art

Ein solcher Gebläsebrenner wird z.B. von der Firma SUPERGAS, jetzt FURI-GAS hergestellt.Such a forced draft burner is e.g. by the company SUPERGAS, now FURI-GAS manufactured.

In der beiliegenden Fig. 1 ist eine schematische perspektivische Darstellung des dem Stand der Technik entsprechenden Gebläsebrenners gezeigt. Der allgemein mit 1 bezeichnete Gebläsebrenner ist im wesentlichen quaderförmig. Seine Oberseite, die das mit dem Lochbild S versehene Brennerblech 3 trägt, ist nach oben ausgewölbt. In Fig. 1 sind die Längskanten des Brennerblechs mit der Bezugszahl 8 und die kürzeren gewölbten Stirnkanten mit 9 bezeichnet.In the accompanying Fig. 1 is a schematic perspective Representation of the state of the art Fan burner shown. The one generally designated 1 Fan burner is essentially cuboid. His Top side, the burner plate provided with the hole pattern S. 3 wears, is arched upwards. In Fig. 1 are the Longitudinal edges of the burner plate with the reference number 8 and the shorter curved front edges designated 9.

Die Querschnittsdarstellung in Fig. 2 zeigt, wie im Stand der Technik das Verteilerblech 4 mit dem Brennergehäuse 2 entlang der Längskante 8 durch eine Schweißnaht 7 und mit dem Brennerblech 3 über an der Längskante 8 desselben angebrachte Noppen 6 und damit korrespondierende Bohrungen 5 im Verteilerblech 4 hergestellt ist. Diese Verbindungen sollen die miteinander korrespondierenden Lochmuster des Brennerblechs 3 und des Verteilerblechs 4 lagemäßig zueinander fixieren. Die Ausdehnung beim Erwärmen der beiden Bleche wird in Längsrichtung durch Langlöcher 5 im Verteilerblech 4 und in Querrichtung durch eine diagonale Anordnung der Noppenfixierung mittels der Noppen 6 gewährleistet.The cross-sectional view in Fig. 2 shows, as in the state the technology, the distributor plate 4 with the burner housing 2 along the longitudinal edge 8 by a weld 7 and with the burner plate 3 over the same along the longitudinal edge 8 attached knobs 6 and corresponding holes 5 is made in the distributor plate 4. These connections the corresponding hole patterns of the Burner plate 3 and the distributor plate 4 positionally fix to each other. The expansion when heating the two sheets is in the longitudinal direction through slots 5 in Distribution plate 4 and in the transverse direction by a diagonal Arrangement of the knob fixation using the knobs 6 guaranteed.

Allerdings besteht bei dem bekannten Gebläsebrenner der Nachteil, daß bei der Montage die Noppen 6 nicht sicher in den zugeordneten Löchern 5 sitzen und die beabsichtigte Fixierung, bedingt durch die Form der Noppen 6 nicht exakt ist. Weiter wird durch Wärmeausdehnung und durch entsprechende Spannungen die Schweißnaht 7 belastet, was teilweise zu Rissen in der Schweißnaht und zu Dauerbrüchen führen kann. Die unbestimmte Lage des Lochmusters des Verteilerblechs zum Brennerblech führt außerdem im Betrieb des Gebläsebrenners zum Pfeifen oder Rauschen.However, in the known fan burner Disadvantage that the knobs 6 are not securely in place during assembly the assigned holes 5 and the intended Fixation, due to the shape of the knobs 6 not exactly is. Next is through thermal expansion and through appropriate stresses on the weld 7, what partly to cracks in the weld seam and to permanent breaks can lead. The undefined position of the hole pattern of the The distributor plate to the burner plate also leads to operation the fan burner to whistle or rustle.

Kurzfassung der ErfindungSummary of the invention

Es ist allgemein Aufgabe der Erfindung, die Qualität des gattungsgemäßen Gebläsebrenners zu verbessern, so daß die genaue Korrespondenz des Lochmusters im Brennerblech mit dem Lochmuster des Verteilerblechs sichergestellt ist und keine Risse mehr in der Schweißnaht auftreten können.It is a general object of the invention, the quality of the Generic fan burner to improve, so that exact correspondence of the hole pattern in the burner plate with the hole pattern of the distributor plate is ensured and no cracks can occur in the weld seam.

Die obige Aufgabe wird bei einem gattungsgemäßen Gebläsebrenner erfindungsgemäß dadurch gelöst, daß die formschlüssige Verbindung des Brennerblechs mit dem Verteilerblech in Form von Lappen am Brennerblech und mit diesen Lappen korrespondierenden Schlitzen im Verteilerblech gebildet ist, durch die die Lappen formschlüssig greifen. The above task is carried out in a generic fan burner solved according to the invention in that the positive connection of the burner plate with the Distribution plate in the form of rags on the burner plate and with slots corresponding to this tab in the distributor plate is formed, through which the rag is form-fitting to grab.

Um eine für die Wärmeabfuhr günstige enge Anlage des Verteilerblechs und des Brennerblechs an der Gehäusewand des Brennergehäuses zu ermöglichen, sind die Lappen vom Brennerblech nach unten abgebogen, d.h. in der der Flammenseite entgegengesetzten Richtung, und durchgreifen so formschlüssig die Schlitze im Verteilerblech.In order for a narrow system of the Distribution plate and the burner plate on the housing wall of the burner housing, the rags are from Burner plate bent down, i.e. in the the Opposite side of the flame, and reach through this is how the slots in the distributor plate fit.

Wie im Stand der Technik sind das Brennerblech und das Verteilerblech vorzugsweise rechteckförmig, und die Lappen am Brennerblech und die damit korrespondierenden Schlitze im Verteilerblech liegen jeweils an zwei einander diagonal gegenüberliegenden Eckabschnitten der rechteckförmigen Bleche. Auf diese Weise wird die durch die Erwärmung der Bleche in Querrichtung bewirkte Ausdehnung aufgefangen.As in the prior art, the burner plate and Distributor plate preferably rectangular, and the rag on the burner plate and the corresponding slots in the distributor plate lie diagonally on two of each other opposite corner sections of the rectangular Sheets. In this way, the warming of the Sheets caught in the transverse direction caused expansion.

Vorzugsweise sind die Schlitze im Verteilerblech als Langlöcher ausgebildet, deren Längsrichtung in Längsrichtung des Verteilerblechs liegt. Auf diese Weise läßt sich die Wärmebedingte Dehnung des Verteilerblechs in dessen Längsrichtung auffangen.The slots in the distributor plate are preferably elongated holes trained, the longitudinal direction in the longitudinal direction of the distributor plate. In this way, the Thermal expansion of the distributor plate in its Catch lengthways.

Vorzugsweise ragen die freien Enden der Lappen des Brennerblechs zur kürzeren Rechteckseite desselben hin, so daß der Innenradius der Lappen zur Mitte des Brennerblechs hinweist.Preferably, the free ends of the tabs of the Burner plate towards the shorter side of the rectangle, see above that the inner radius of the lobes to the center of the burner plate points.

Damit die Lappen mit größerem Innenradius ausgeführt werden können, weist die diesem Innenradius benachbarte Längsseite der Langlöcher eine Durchstellung in Richtung des freien Endes des Lappens auf.So that the flaps are executed with a larger inner radius can, the longitudinal side adjacent to this inner radius of the elongated holes an extension towards the free End of the rag.

Vorzugsweise wird die im Stand der Technik übliche Schweißnaht, die das Verteilerblech mit der Gehäusewandung verbindet, durch eine formschlüssige Verbindung des Verteilerblechs mit dem Gehäuse ersetzt, die die durch die Wärmeausdehnung und die Spannung auf die Schweißnaht verursachten Dauerbrüche vermeidet.Preference is given to that which is customary in the prior art Weld that the distributor plate with the housing wall connects through a positive connection of the Distributor plate with the housing replaced by the Thermal expansion and tension on the weld avoids long-term breaks.

Die formschlüssige Verbindung des Brennergehäuses mit dem Verteilerblech kann entweder durch Lappen des Verteilerblechs, die entsprechende Löcher oder Schlitze im Brennergehäuse durchgreifen, oder alternativ durch am Brennergehäuse gebildete, nach innen ragende Lappen ausgeführt sein, die die Längskanten des Verteilerblechs so umgreifen, daß dieses in der Innenwölbung des Gehäuses verspannt ist.The positive connection of the burner housing with the The distributor plate can either be the corresponding holes or slots in the Reach through the burner housing, or alternatively by Burner housing formed inwardly projecting lobes be carried out so the longitudinal edges of the distributor plate grasp that this in the inner curvature of the housing is tense.

Nachstehend werden verschiedene Ausführungsformen der Erfindung anhand der Zeichnungsfiguren 3 bis 5 näher beschrieben.Various embodiments of the Invention with reference to the drawing figures 3 to 5 described.

Der Lappen 16 greift durch einen korrespondierenden Schlitz 15 im Verteilerblech 14. Letzteres ist durch eine Schweißverbindung 17 am Brennergehäuse 12 fixiert. Aus der Fig. 3 ist nicht ersichtlich, daß das Brennerblech 13 zwei Lappen 16 aufweist, die jeweils an einander diagonal gegenüberliegenden Eckabschnitten des Brennerblechs 13 abgebogen sind. Ferner sind die Schlitze 15 als Langlöcher ausgebildet, deren Längsseite in Längsrichtung des Verteilerblechs 14 ausgerichtet ist. Damit der Innenradius des Lappens bzw. der Lappen 16 möglichst groß ausfallen kann, sind die Längsseiten der die Schlitze 15 im Verteilerblech 14 bildenden Langlöcher nach unten ausgebogen, d.h. daß das Verteilerblech 14 an dieser Stelle eine zum freien Ende der Lappen 16 hinweisende Durchstellung aufweist. Damit sowohl das Verteilerblech 14 als auch das Brennerblech 13 möglichst dicht an der Innenwand des Brennergehäuses 12 anliegen können, hat das Brennergehäuse 12 eine in Längsrichtung verlaufende Stufe 10.The cross-sectional view in Fig. 3, the sectional plane through the attachment points of the burner plate 13 on Distribution plate 14 and the latter on the burner housing 12 is placed, shows that the burner plate 13 near the Long edge 18 one down, i.e. from the flame side bent tabs 16. The tab 16 reaches through a corresponding slot 15 in the distributor plate 14. The latter is by a weld 17 on the burner housing 12 fixed. 3 does not show that the burner plate 13 has two tabs 16, the each at diagonally opposite corner sections of the burner plate 13 are bent. Further the slots 15 are formed as elongated holes, the Longitudinal side in the longitudinal direction of the distributor plate 14 is aligned. So that the inner radius of the flap or the flap 16 can be as large as possible Long sides of the slots 15 in the distributor plate 14 forming elongated holes bent down, i.e. that this Distribution plate 14 at this point one to the free end of the Rag 16 has indicative passage. So both the distributor plate 14 and the burner plate 13 as close as possible to the inner wall of the burner housing 12 can apply, the burner housing 12 has an in Longitudinal step 10.

    Mit den oben anhand der Fig. 3 beschriebenen Maßnahmen läßt sich erreichen, daß das Lochmusters des Brennerblechs 13 genau zum korrespondierenden Lochmuster des Verteilerblechs 14 trotz der durch die Erwärmung verursachten Ausdehnung ausgerichtet ist und innerhalb der rechteckigen Öffnung des Brennergehäuses 12 zu liegen kommt.With the measures described above with reference to FIG. 3 achieve that the hole pattern of the burner plate 13th exactly to the corresponding hole pattern of the distributor plate 14 despite the expansion caused by the warming is aligned and within the rectangular opening of the Burner housing 12 comes to rest.

    Fig. 4 zeigt eine zweite erfindungsgemäße Ausführungsform des Gebläsebrenners. Die Fixierung des Brennerblechs 13 am Verteilerblech 24 ist genauso ausgeführt wie bei der in Fig. 3 gezeigten Ausführungsform. Anders ausgeführt ist in Fig. 4 jedoch die Verbindung des Verteilerblechs 24 an dem Brennergehäuse 22. Hierzu weist das Verteilerblech 24 nach oben, d.h. in Richtung der Flammenseite abgebogene Lappen 25, und das Brennergehäuse 22 entsprechende Langlöcher 23 auf, durch die die Lappen 25 greifen. Die in Fig. 4 gezeigte Fixierung des Verteilerblechs 24 am Brennergehäuse 22 vermeidet die Schweißnaht 17 gemäß Fig. 3 und trägt dazu bei, die Temperaturbeständigkeit des Brenners noch mehr zu verbessern.4 shows a second embodiment according to the invention of the forced draft burner.
