Description
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.
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
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

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
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.
Die Querschnittsdarstellung in Fig. 3, deren Schnittebene
durch die Befestigungsstellen des Brennerblechs 13 am
Verteilerblech 14 und des letzteren am Brennergehäuse 12
gelegt ist, zeigt, daß das Brennerblech 13 nahe der
Längskante 18 einen nach unten, d.h. von der Flammenseite
weggebogenen Lappen 16 aufweist. 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

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

Brennergehäuses 32 derart eingesetzt, daß die Lappen 31 des
Brennergehäuses 32 das Verteilerblech 34 unter Vorspannung
im Gehäuseinneren verklemmen. Damit eine für einen guten
Temperaturübergang vom Brennerblech 13 und vom
Verteilerblech 34 zum Brennergehäuse 32 gewünschte enge
Anlage desselben am Verteilerblech und am Brennerblech
ermöglicht ist, weist das Brennergehäuse 32 ähnlich wie in
Fig. 3 eine Stufe 35 auf, die in Längsrichtung des
Brennergehäuses, d.h. parallel zur Längskante 38 geht.
Sämtliche Verbindungen der in den Figuren 3 bis 5
dargestellten Ausführungsformen sind fertigungstechnisch
einfach und kostengünstig herstellbar. Die verschiedenen
Lappen 16, 25 und 31 können durch einen Stanz- und
Biegeschritt an den Blechen angebracht werden. Die Schlitze
15 in den Verteilerblechen 14 und 24 können vorteilhaft
zusammen mit den Lochmustern, beispielsweise durch
Lasertechnologie, gebildet werden. Die Durchstellungen 19
können durch eine Biegevorgang, in Fig. 4 z.B., zusammen
mit dem Biegen der Lappen 25 gebildet werden.This is because in the embodiment in FIG
