Description

Die vorliegende Erfindung bezieht sich auf einen Gasbrenner gemäß dem ersten Teil des Anspruchs 1.The present invention relates to a gas burner according to the first part of claim 1.

Ein solcher Gasbrenner ist bekanntgeworden aus der DE-C-355 384, die sich mit einer Regelung der Gas- und Luftzufuhr für einen Gaskocher befaßt. Gegenüber diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, im Zentrum des Brennerkörpers einen Luftstrom zu erzeugen, der nach außen abgelenkt wird, so daß über diese Ablenkung die außenbrennenden Flammen am Brennerkörper ihrerseits mit abgelenkt werden und nicht mit einer kalten Fläche eines zu beheizenden Bauteils, wie eines Kochers, einer Absorptionswärmepumpe, in Berührung kommen können.Such a gas burner has become known from DE-C-355 384, which deals with regulating the gas and air supply for a gas cooker. Compared to this prior art, the invention has for its object to generate an air flow in the center of the burner body, which is deflected to the outside, so that the outside burning flames on the burner body are in turn deflected with this deflection and not with a cold surface of one to be heated Component, such as a stove, an absorption heat pump can come into contact.

Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved by the characterizing features of claim 1.

Weitere Ausgestaltungen und besonders vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche beziehungsweise gehen aus der nachfolgenden Beschreibung hervor, die ein Ausführungsbeispiel der Erfindung anhand der Figur der Zeichnung näher erläutert. Die Zeichnung zeigt einen Brenner in einer Seitenansicht, teilweise geschnitten.Further refinements and particularly advantageous developments of the invention are the subject of the subclaims or emerge from the following description, which explains an exemplary embodiment of the invention with reference to the figure of the drawing. The drawing shows a burner in a side view, partially cut.

Bei dem in der Figur dargestellten Brenner handelt es sich entweder um einen Gasbrenner. Es kann sich um einen atmosphärischen Brenner wie auch um einen Gebläsebrenner handeln, wenn er als Gebläsebrenner ausgebildet ist, kann das Gebläse im Zuge der anströmenden Frischluft oder auch abgasseitig angeordnet sein. Der Brenner ist eine geschweißte Blechkonstruktion und weist einen Zylinderkörper 1 auf, der einen Zylindermantel 2, einen untenliegenden eingesetzten Boden 3 und einen obenliegenden eingesetzten Deckel 4 aufweist. Der Zylinderkörper ist somit als Hohlkörper ausgestaltet und weist einen Außenmantel 5 und einen Innenmantel 6 auf, der einen zylindrischen Hohlraum 7 umschließt. Sowohl der Boden als auch der Deckel weisen eine kreisrunde Ausnehmung 8 beziehungsweise 9 auf, die aber unterschiedlichen Durchmesser aufweisen. Von beiden Ausnehmungen aufgenommen und getragen ist ein im Inneren des Hohlraums 7 angeordneter Kegelstumpfkörper 10, der mit seinem Ende mit dem kleineren Durchmesser in der Ausnehmung 8 des Bodens 3 befestigt ist. Das Ende mit dem größeren Durchmesser ist demgemäß in der Ausnehmung 9 des Deckel 4 befestigt. Auch der Kegelstumpfkörper ist ein Blechhohlteil mit einem Außenmantel 11 und einem Innenmantel 12. Der Innenraum 13 des Kegelstumpfkörpers ist am oberen und unteren Ende offen, so daß er einen kegelstumpfförmigen Luftkanal bildet, in dem Luft in Richtung der Pfeile 14 ein- und ausströmen kann. Somit ist der eigentliche Innenraum 7, eingeschlossen vom Innenmantel 6 des Zylinderkörpers 1 und vom Außenmantel 11 des Kegelstumpfkörpers 10 und stirnseitig begrenzt von den beiden Abdeckungen des Deckels 4 und des Bodens 3, als Ringraum zu verstehen, dessen Querschnitt im Bodenbereich größer als im Deckbereich ist. Dieser Ringraum steht mit einem Zufuhrrohr 15 pneumatisch in Verbindung. Durch dieses Zufuhrrohr 15 wird entweder ein Gas oder ein Gas-/Luftgemisch zugeführt.The burner shown in the figure is either a gas burner. It can be an atmospheric burner as well as a fan burner, if it is designed as a fan burner, the fan can be arranged in the course of the incoming fresh air or also on the exhaust side. The burner is a welded sheet metal construction and has a cylinder body 1 which has a cylinder jacket 2, a bottom 3 inserted underneath and a lid 4 inserted above. The cylinder body is thus designed as a hollow body and has an outer jacket 5 and an inner jacket 6, which encloses a cylindrical cavity 7. Both the bottom and the lid have a circular recess 8 and 9, but which have different diameters. Received and supported by both recesses is a truncated cone body 10 arranged in the interior of the cavity 7, the end of which is fastened with the smaller diameter in the recess 8 of the base 3. The end with the larger diameter is accordingly fastened in the recess 9 of the cover 4. The truncated cone body is also a hollow sheet metal part with an outer casing 11 and an inner casing 12. The interior 13 of the truncated cone body is open at the upper and lower ends, so that it forms a frustoconical air duct in which air can flow in and out in the direction of the arrows 14. Thus, the actual interior 7, enclosed by the inner jacket 6 of the cylinder body 1 and by the outer jacket 11 of the truncated cone body 10 and limited on the face side by the two covers of the cover 4 and the base 3, is to be understood as an annular space, the cross section of which is larger in the base area than in the cover area . This annular space is pneumatically connected to a feed pipe 15. Through this supply pipe 15 either a gas or a gas / air mixture is supplied.

Oberhalb des Deckels 4 ist ein Kegelblech 16 vorgesehen, dessen Spitze 17 nach unten gerichtet ist und in den Innenraum 13 des Kegelstumpfkörpers tief hineinragt. Die Basis 18 des Kegels ist nach oben gerichtet und liegt parallel zu einer höheren Ebene als die des Bodens 4. Der Kegelkörper 16 ist durch drei regelmäßig angeordnete Stege 19 mit dem Boden 3 beziehungsweise dem obersten Rand des Mantels 2 verbunden. Die Stege können einseitige Verlängerungen des Kegelkörpers 16 bilden, sie können auch gesonderte an den Kegelkörper 16 angeschweißte Blechstreifen sein. Die Stege sind mit dem Mantel beziehungsweise dem Boden 3 des Zylinderkörpers 1 verschweißt. Diese Verschweißung kann zusammen in einem Arbeitsgang mit dem Verschweißen des Bodens 4 erfolgen. Die Längsachsen beziehungsweise Symmetrieachsen des Kegelkörpers 16, die des Kegelstumpfkörpers 10, die des Zylinderkörpers 1 und die des Deckels 4 beziehungsweise die des Bodens 3 fluchten miteinander. Zwischen dem Außenmantel 20 des Kegelkörpers und dem oberen Ende des Kegelstumpfkörpers 10 entsteht eine kreisringförmige Öffnung 21, durch die die unten gemäß dem Pfeil 14 einströmende Luft ringförmig gemäß den Pfeilen 22 abströmen kann. Der Kegelkörper 16 dient somit als Ablenkvorrichtung.A conical plate 16 is provided above the cover 4, the tip 17 of which is directed downward and projects deeply into the interior 13 of the truncated cone body. The base 18 of the cone is directed upwards and is parallel to a higher plane than that of the base 4. The cone body 16 is connected to the base 3 or the uppermost edge of the jacket 2 by three regularly arranged webs 19. The webs can form unilateral extensions of the cone body 16, they can also be separate sheet metal strips welded to the cone body 16. The webs are welded to the jacket or the bottom 3 of the cylinder body 1. This welding can be done together with the welding of the bottom 4 in one operation. The longitudinal axes or axes of symmetry of the cone body 16, that of the truncated cone body 10, that of the cylinder body 1 and that of the cover 4 or that of the base 3 are aligned with one another. Between the outer jacket 20 of the cone body and the upper end of the truncated cone body 10, an annular opening 21 is formed, through which the air flowing in at the bottom according to the arrow 14 can flow out in a ring shape according to the arrows 22. The cone body 16 thus serves as a deflection device.

Die Basis 18 des Kegelkörpers besitzt einen kleineren Durchmesser als der Zylinderkörper 1. Aus diesem Grunde kann der Außenrand der Basis 18 des Kegelkörpers 16 nicht in den Bereich der Flammen geraten, die am Außenmantel 5 des Zylinderkörpers 1 aufgrund von Brennschlitzen 23 gebildet werden. Diese Brennschlitze sind in regelmäßiger Form über den gesamten Umfang des Außenmantels 2 des Zylinderkörpers 1 verteilt. Die Querschnittsfläche des Ringspalts ist so bemessen, daß sie etwa 2/3 des freien Öffnungsquerschnittes am Auslaß des oberen Endes des Kegelstumpfkörpers 10 ausmacht. Der Ringspalt verhält sich mit seiner freien Größe zu der Größe des Einlaßquerschnitts an der Unterseite des Kegelstumpfkörpers wie 1 zu 3 bis 1 zu 4.The base 18 of the cone body has a smaller diameter than the cylinder body 1. For this reason, the outer edge of the base 18 of the cone body 16 cannot get into the area of the flames which are formed on the outer jacket 5 of the cylinder body 1 due to combustion slots 23. These burn slots are distributed in a regular form over the entire circumference of the outer shell 2 of the cylinder body 1. The cross-sectional area of the annular gap is dimensioned such that it makes up approximately 2/3 of the free opening cross section at the outlet of the upper end of the truncated cone body 10. With its free size, the annular gap relates to the size of the inlet cross section on the underside of the truncated cone body as 1 to 3 to 1 to 4.

Im Ausführungsbeispiel der Figur ist der Innenmantel des Zylinderkörpers zylindrisch, der Außenmantel des Kegelstumpfkörpers keglig ausgebildet, so daß sich der freie Ringraum 7 zwischen beiden Mänteln nach oben hin verjüngt. Dies dient dazu, den Austrittsdurchsatz an Brennstoff durch die Schlitze 23 am Außenmantel 2 des Zylinderkörpers 1 im Höhenniveau zu vergleichmäßigen. Es soll verhindert werden, daß die Flammen im höheren Bereich des Zylinderkörpers größer werden als die im tieferen Bereich. Diese Maßnahme kann natürlich auch dadurch erreicht werden, daß der Innenkörper, also der Kegelstumpfkörper 10, als Zylinder. ausbildet und dafür der Außenkörper, das heißt den Zylinderkörper 1, keglig gestaltet sind. Dieser müßte dann einen aufrecht stehenden Kegel aufweisen, der kegelstumpfförmig gestaltet wäre, wobei das Ende mit dem kleineren Durchmesser des Kegels oben liegen würde. Auch dann würde sich der Ringraum 7 zwischen beiden Teilen nach oben hin im Querschnitt verkleinern.In the exemplary embodiment of the figure, the inner jacket of the cylinder body is cylindrical, the outer jacket of the truncated cone body is conical, so that the free annular space 7 between the two jackets tapers towards the top. This serves to even out the throughput of fuel through the slots 23 on the outer jacket 2 of the cylinder body 1 at the height level. It is to be prevented that the flames in the higher area of the Cylinder body become larger than that in the lower area. This measure can of course also be achieved in that the inner body, ie the truncated cone body 10, as a cylinder. trained and the outer body, that is, the cylinder body 1, are conical. This would then have to have an upright cone which would have the shape of a truncated cone, the end with the smaller diameter of the cone being at the top. Then, too, the annular space 7 between the two parts would decrease in cross-section.

Schließlich könnte noch daran gedacht werden, sowohl den Zylinderkörper 1 so keglig zu gestalten, daß sein Durchmesser nach oben hin kleiner wird, als auch den Zylinderstumpfkörper 10 so auszuführen, daß sein Durchmesser mit tieferen Bereichen kleiner wird, also beide Bauteile keglig auszugestalten. Durch unterschiedliche Bemessung der Kegelwinkel könnte dann auch erreicht werden, daß der Zwischenraum 7 zwischen den beiden Bauteilen mit wachsender Höhe kleiner wird.Finally, it could also be considered to design the cylinder body 1 so that its diameter becomes smaller towards the top, and also to design the cylinder stump body 10 so that its diameter becomes smaller with deeper areas, that is to say to design both components to be conical. By differently dimensioning the cone angle, it could also be achieved that the space 7 between the two components becomes smaller with increasing height.

Weiterhin wäre es denkbar, den Zylinderkörper 1 nicht kreisrund, sondern zum Beispiel prismatisch auszugestalten. So könnte auch der Kegelstumpfkörper ein Vieleck sein. Bei beiden Bauteilen können auch dann unabhängig von der Prismenformgebung die vorstehend erläuterten Verjüngungsgedanken zum Ansatz kommen, so daß also entweder das Außenteil oder das Innenteil oder beide Teile pyramidenartig ausgestaltet werden würden. Bei einer solchen Ausgestaltung ist eine Verengung des Ringquerschnitts zwischen beiden Körpern denkbar.Furthermore, it would be conceivable not to design the cylinder body 1 as circular, but for example prismatic. The truncated cone body could also be a polygon. In both components, regardless of the shape of the prism, the above-mentioned tapering ideas can also be used, so that either the outer part or the inner part or both parts would be designed pyramid-like. With such a configuration, a narrowing of the ring cross section between the two bodies is conceivable.

Der Brenner gemäß dem Ausführungsbeispiel weist folgende Funktionen auf:The burner according to the exemplary embodiment has the following functions:

Durch das Zufuhrrohr 15 wird ein Brenngas oder ein Brenngas-Luftgemisch in den Ringraum 7 eingeblasen beziehungsweise aus der Verbrennungskammer her angesaugt. Dieses Brenngas-Luftgemisch steigt in dem Ringraum 7 nach oben und tritt gleichmäßig über den Umfang verteilt und auch gleichmäßig in der Höhe verteilt durch die einzelnen Brennschlitze 23 aus. Durch einen nicht dargestellten Zündbrenner wird das Brengasgemisch gezündet und verbrannt, indem in jedem Fall von der Außenseite des Außenmantels 5 des Zylinderkörpers 1 Sekundärluft zugefügt wird. Die am Außenmantel aufsteigenden Abgase streichen in dem Bereich des Ringspaltes zwischen dem Mantel des Zylinderkörpers 1 und der Basis 18 des Kegels 16 vorbei und saugen durch dieses Vorbeiströmen Tertiärluft durch den Ringspalt an, die von unten her gemäß den Pfeilen 14 nachströmt. Durch diese in dem Ringspalt austretende Tertiärluft werden die Abgase radial nach außen abgelenkt, so daß sie von einem unmittelbar oberhalb der Basis 18 angeordneten unteren Ende eines Kesselgefäßes oder dergleichen abgelenkt werden. Statt eines Kegelkörpers 16 könnte im übrigen auch eine Kugel, Halbkugel oder Kugelabschnitt als Ablenkkörper verwendet werden. Schließlich wäre auch ein Pyramidenkörper denkbar.A fuel gas or a fuel gas / air mixture is blown into the annular space 7 or sucked out of the combustion chamber through the feed pipe 15. This fuel gas-air mixture rises in the annular space 7 and emerges evenly distributed over the circumference and evenly distributed in height through the individual combustion slots 23. The fuel gas mixture is ignited and burned by a pilot burner, not shown, in each case by adding secondary air from the outside of the outer casing 5 of the cylinder body 1. The exhaust gases rising on the outer jacket sweep past in the area of the annular gap between the jacket of the cylinder body 1 and the base 18 of the cone 16 and suck in tertiary air through the annular gap, which flows in from below according to the arrows 14. The exhaust gases are deflected radially outward by this tertiary air emerging in the annular gap, so that they are deflected by a lower end of a boiler vessel or the like arranged directly above the base 18. Instead of a conical body 16, a ball, hemisphere or spherical section could also be used as a deflecting body. Finally, a pyramid body would also be conceivable.
