Description

Die Erfindung bezieht sich auf einen gebläseunterstützten Brenner gemäß dem Oberbegriff des Anspruches 1.The invention relates to a fan-assisted burner according to the preamble of claim 1.

Bei bekannten derartigen Brennern ist der Brenner auf einem Flansch montiert, der eine Öffnung eines Brennraumes abdeckt, wobei an dem Brenner ein weiterer Flansch montiert ist, an dem eine Luftleitung angeschlossen ist.In known such burners, the burner is mounted on a flange, the one Cover opening of a combustion chamber, with another flange mounted on the burner to which an air line is connected.

Bei dieser bekannten Lösung ergibt sich der Nachteil einer relativ aufwendigen Konstruktion.This known solution has the disadvantage of a relatively complex construction.

Ziel der Erfindung ist es, diesen Nachteil zu vermeiden und einen Brenner der eingangs erwähnten Art vorzuschlagen, der sich durch einen einfachen und kompakten Aufbau auszeichnet.The aim of the invention is to avoid this disadvantage and a burner at the beginning to propose the type mentioned, which is simple and compact distinguished.

Erfindungsgemäß wird dies bei einem Brenner der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention, this is achieved by a burner of the type mentioned at the outset characteristic features of claim 1 achieved.

Durch die vorgeschlagenen Maßnahmen ergibt sich der Vorteil, daß das Gebläse und der Brenner auf einem einzigen Flansch angeordnet sind und sich daher eine sehr einfache Konstruktion ergibt. Dabei ergibt sich auch der Vorteil, daß das Gas konzentrisch zur zentralen als Luftleitung dienenden Bohrung in den Brennraum einströmt und sich daher sehr gut mit der Luft vermischt. Dadurch ergibt sich eine sehr gute Verbrennung und ein nur sehr geringer Schadstoffausstoß.The proposed measures have the advantage that the blower and the Burners are arranged on a single flange and are therefore very simple Construction results. This also has the advantage that the gas is concentric with central bore serving as air duct flows into the combustion chamber and therefore very well mixed with the air. This results in a very good combustion and only one very low emissions.

Durch die vorgeschlagenen Maßnahmen ist auch sichergestellt, daß das Gas im wesentlichen gleichmäßig in den Brennraum einströmt, wodurch sich sehr günstige Verbrennungsverhältnisse ergeben.The proposed measures also ensure that the gas in flows substantially evenly into the combustion chamber, making it very cheap Combustion conditions result.

Durch die Merkmale des Anspruches 2 ergibt sich der Vorteil einer relativ einfachen Gestaltung der Dichtung.The features of claim 2 result in the advantage of being relatively simple Design of the seal.

Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:

  • Fig. 1 schematisch eine teilweise geschnittene Ansicht eines erfindungsgemäßen Brenners und
  • Fig. 2 eine Explosionsdarstellung des Brenners nach der Fig. 1.
    • The invention will now be explained in more detail with reference to the drawing. Show:
  • Fig. 1 shows schematically a partially sectioned view of a burner according to the invention and
  • FIG. 2 shows an exploded view of the burner according to FIG. 1.

    • Gleiche Bezugszeichen bedeuten in beiden Figuren gleiche Einzelteile.The same reference symbols in both figures mean the same individual parts.

    Der erfindungsgemäße Brenner weist ein Gebläse 1 auf, das auf einer Platte 2 befestigt ist. Auf dieser Platte 2 ist auch ein Stutzen 3 angeordnet, der für den Anschluß einer Gasleitung dient.The burner according to the invention has a fan 1 which is fastened on a plate 2. On this plate 2, a nozzle 3 is also arranged, for the connection of a gas line serves.

    Diese Platte 2 weist an ihrer vom Gebläse 1 abgekehrten Seite eine Vertiefung 8 auf, die über eine Bohrung 9 mit dem Stutzen 3 verbunden ist. Diese Vertiefung 8 erstreckt sich von der Bohrung 9 bis zu einem eine als Luftleitung dienende Bohrung 10 umgebenden Ring 11, wobei dieser Ring 11 mit Spiel von dem Rand der Vertiefung 8 umgeben ist.This plate 2 has a recess 8 on its side facing away from the blower 1 is connected to the nozzle 3 via a bore 9. This recess 8 extends from the bore 9 up to a ring 11 surrounding a bore 10 serving as an air duct, this ring 11 is surrounded with play by the edge of the recess 8.

    An der Platte 2 liegt eine Dichtung 4 an, die die Vertiefung 8 überdeckt und auch an der Stirnseite des Ringes 11 anliegt. Dabei liegt die Dichtung 4 mit einem rohrartigen Abschnitt 12 auf der Stirnseite des Ringes 11 an, wobei dieser rohrartige Abschnitt 12 der Dichtung 4 in einem Durchbruch 14 über Arme gehalten ist, die den rohrartigen Abschnitt 12 mit dem übrigen Teil der Dichtung 4 verbindet. Dabei fluchtet die Bohrung 10' des rohrartigen Abschnittes 12 mit der Bohrung 10 der Platte 2.On the plate 2 is a seal 4, which covers the recess 8 and also on the Face of the ring 11 is applied. The seal 4 lies with a tubular section 12 on the end face of the ring 11, this tubular section 12 of the seal 4 is held in an opening 14 via arms, which the tubular section 12 with the connects the remaining part of the seal 4. The bore 10 'of the tubular is aligned Section 12 with the bore 10 of the plate 2nd

    An der Unterseite der Dichtung 4 liegt an dieser eine Abdeckplatte 5 an, die einen koaxial mit der Bohrung 10 fluchtenden Durchbruch 13 aufweist, in dem eine Dralleinrichtung 7 angeordnet ist.On the underside of the seal 4 there is a cover plate 5, which is coaxial with the bore 10 aligned opening 13 in which a swirl device 7th is arranged.

    Dieser Durchbruch 13 ist von einem koaxial zu diesem angeordneten Kranz von Düsenbohrungen 6 umgeben. Diese Düsenbohrungen 6 verbinden den durch die Vertiefung 8 und die Dichtung 4 begrenzten Gasraum mit der Außenseite der Abdeckplatte 5.This opening 13 is of a ring arranged coaxially to this Surround nozzle holes 6. These nozzle bores 6 connect the through the recess 8 and the seal 4 delimited gas space with the outside of the cover plate 5.

    Im Betrieb wird vom Gebläse 1 Luft angesaugt und durch die Bohrung 10 der Platte 2 und die Bohrung 10' der Dichtung 4, sowie den Durchbruch 13 gedrückt, wobei sie durch die Dralleinrichtung 7 verwirbelt wird.In operation, air is drawn in by the blower 1 and through the bore 10 of the plate 2 and the bore 10 'of the seal 4, as well as the opening 13, being pushed through the Swirl device 7 is swirled.

    Gleichzeitig gelangt Gas über eine nicht dargestellte Gasleitung und den Stutzen 3, sowie die Bohrung 9 der Platte 2 in einen durch die Vertiefung 8 gebildeten Gasraum. Aus diesem tritt das Gas über die Düsenbohrungen 6 der Abdeckplatte 5 aus, wobei die Düsenbohrungen 6 im Bereich des den Ring 11 der Platte 2 umgebenden Raumes angeordnet sind. At the same time, gas passes through a gas line, not shown, and the nozzle 3, and the bore 9 of the plate 2 in a gas space formed by the recess 8. For this the gas exits through the nozzle bores 6 of the cover plate 5, the Nozzle bores 6 in the area of the space surrounding the ring 11 of the plate 2 are arranged.

    Das ausströmende Gas vermischt sich mit der verwirbelten Luft, wodurch sich ein sehr homogenes Gemisch ergibt.The escaping gas mixes with the swirled air, creating a very homogeneous mixture results.
