 bindung, in dem eine Klappe 19 vorgesehen ist. 



   Die Wirkungweise der Anordnung ist folgende :
Bei Zündung der Flamme an der Düse 2 wird über die Kanäle 6 und 7 die notwendige Verbren-   nungsluft zugeführt. Dabei wird durch entsprechende Einstellung der Stellschieber 10 und 11   sichergestellt, dass die vom Luftzufuhrkanal 7 ausströmende Luft eine höhere Geschwindigkeit aufweist als die vom inneren Luftzufuhrkanal 6   ausströmende Luft. Dadurch bilden sich im Bereich der Brennerdüse   2 starke Luftwirbel aus, die zu einer intensiven Vermischung der Verbrennungsluft mit dem an der Brennerdüse 2 zerstäubt austretenden Brennstoff führt. Auf diese Weise kann die Flamme an der Brennerdüse 2 stabilisiert werden. Die intensive Vermischung der aus den beiden Luftzufuhrkanälen ausströmenden Medien wird weiters auch noch durch die im Kanal 6 vorgesehenen Drallbleche erhöht. 



   Der besondere Vorteil dieser Vorrichtung ist somit darin zu sehen, dass auf die bisher üblichen Stauscheiben in der Verbrennungsluftzuführung verzichtet werden kann. Weiters kann durch die intensive Vermischung der Brennstoffe mit der Verbrennungsluft der Raum 5 vor der Brennerdüse 2, ohne die übliche Abschrägung, unter einem rechten Winkel in den Hauptbrennraum münden, ohne dass ein Entweichen unverbrannter Gase befürchtet werden muss. Zudem kann die Form der Flamme stark beeinflusst werden. 



   Durch die Möglichkeit, die durch die beiden Kanäle 6 und 7 zugeführten Mengen der Verbrennungsluft in weiten Grenzen zu variieren, kann die Flamme beeinflusst werden. 



   PATENTANSPRÜCHE : 
1. Anordnung für Zerstäubungsbrenner, insbesondere solche mit Zerstäubung durch ein Ultraschallfeld, mit einem Düsenbrennerrohr und zwei konzentrisch zu diesem liegenden Zuführungen der Verbrennungsluft, denen Einrichtungen zur Steuerung der zuströmenden Luft zugeordnet sind,   dadurch   gekennzeichnet, dass die Strömungsgeschwindigkeit der Luft im äusseren Kanal (7) grösser ist als jene im inneren Kanal (6).

 binding in which a flap 19 is provided.



   The mode of operation of the arrangement is as follows:
When the flame is ignited at nozzle 2, the necessary combustion air is supplied via channels 6 and 7. By setting the adjusting slides 10 and 11 accordingly, it is ensured that the air flowing out from the air supply channel 7 has a higher speed than the air flowing out from the inner air supply channel 6. As a result, strong air eddies form in the area of the burner nozzle 2, which leads to an intensive mixing of the combustion air with the fuel emerging in atomized form at the burner nozzle 2. In this way, the flame at the burner nozzle 2 can be stabilized. The intensive mixing of the media flowing out of the two air supply ducts is further increased by the swirl plates provided in duct 6.



   The particular advantage of this device is therefore to be seen in the fact that the baffle plates in the combustion air supply that were customary up to now can be dispensed with. Furthermore, due to the intensive mixing of the fuels with the combustion air, the space 5 in front of the burner nozzle 2 can open into the main combustion chamber at a right angle without the usual bevel, without the risk of unburned gases escaping. In addition, the shape of the flame can be greatly influenced.



   The flame can be influenced by the possibility of varying the quantities of combustion air supplied through the two channels 6 and 7 within wide limits.



   PATENT CLAIMS:
1. Arrangement for atomizing burners, in particular those with atomization by an ultrasonic field, with a nozzle burner tube and two concentrically to this lying inlets of the combustion air, to which devices for controlling the inflowing air are assigned, characterized in that the flow speed of the air in the outer channel (7 ) is larger than that in the inner canal (6).

 

Claims (1)

2. Anordnung nach Anspruch 1, dadurch gekennzeichnet, dass der innere Luftkanal (6) annähernd konstanten Querschnitt aufweist und nahe der Mündung in den Brennraum mit, vorzugsweise zur Längsachse 30-600 geneigten Drallblechen (8) versehen ist, wogegen sich der Querschnitt des äusseren Luftkanals (7) vor der Mündung in den Brennraum verengt, um so die Strömungsgeschwindigkeit der Luft zu erhöhen. 2. Arrangement according to claim 1, characterized in that the inner air duct (6) has an approximately constant cross section and is provided near the opening in the combustion chamber with swirl plates (8), preferably inclined to the longitudinal axis 30-600, whereas the cross section of the outer one Air duct (7) is narrowed in front of the opening into the combustion chamber in order to increase the flow speed of the air.
