Vorrichtung zum Zerstäuben von BrennstoffDevice for atomizing fuel

Die Erfindung betrifft eine Vorrichtung zum Zerstäuben von Brennstoff, insbesondere zur Verwendung In Gasturbinen, bei der in einem rohrförmigen Körper ein der Misohluftzufuhr dienender zylinderförmiger Einsatz angeordnet ist, an dessen Austrittsende eine aus einer Mehrzahl von Brallplätten bestehende Dralleinriehtung sitzt, welcherder Brennstoff durch einen Ringkanal zwischen dem zylinderförmigen Einsatz und dem rohrförmigen Körper zugeführt wird.The invention relates to a device for atomizing Fuel, in particular for use in gas turbines the one in a tubular body one of the miso air supply Serving cylindrical insert is arranged on the Exit end one consisting of a plurality of firing plates Swirl device sits, which the fuel through an annular channel between the cylindrical insert and is supplied to the tubular body.

Zweck der Erfindung ist es, eine Vorrichtung mit den angegebenen Merkmalen in ihrer Wirksamkeit zu verbessern.The purpose of the invention is to provide a device with the specified To improve characteristics in their effectiveness.

Dies wird gemäß der Erfindung dadurch erreicht, daß der Ringkanal an seinem Austrittsende eine Stirnwand aufweist, in der eine Mehrzahl düsenförmiger Öffnung vorgesehen sind, wobei im Bereich der Ströraungsrichtung der Öffnungen eine nach innen gerichtete, ringförmige Rippe angeordnet ist, die denThis is achieved according to the invention in that the annular channel has an end wall at its outlet end, in which a plurality of nozzle-shaped openings are provided, wherein in the area of the flow direction of the openings one after inwardly directed, annular rib is arranged, which the

Besonders zweckmäßige Ausführüngsformen dieser Erfindung sind in der Beschreibung und den Ansprüchen erläutert, auf die verwiesen wird.Particularly useful embodiments of this invention are in the description and claims to which reference is made.

Die Erfindung ist unter Bezugnahme auf die Zeichnung beispielshalber erläutert. Es zeigen: The invention is explained by way of example with reference to the drawing. Show it:

Fig. 1 die Vorrichtung gemäß der Erfindung im Längsschnitt und Fig. 1 shows the device according to the invention in longitudinal section and

Fig. 2 eine weitere Ausführungsform der Erfindung nach Fig. 1.Fig. 2 shows a further embodiment of the invention Fig. 1.

Die in Fig. 1 dargestellte Vorrichtung zum Zerstäuben von Brennstoff umfaßt einen rohrförmigen Körper 10 von zusammengesetzter Bauweise. Der Körper 10 wird an einem Ende von einem Tragteil 11 gehalten, durch den sich ein Brennstoffversorgungskanal 12 erstreckt. Innerhalb des anderen Endes des Körpers 10 ist eine Dralleinrichtung IJ angeordnet, die einen konisch expandierenden Luftstrom unmittelbar am Austrittsende des Körpers 10 erzeugt.The apparatus for atomizing fuel shown in Fig. 1 comprises a tubular body 10 of composite construction. The body 10 is held at one end by a support part 11 through which a fuel supply channel 12 extends. A swirl device IJ is arranged inside the other end of the body 10 and generates a conically expanding air flow directly at the outlet end of the body 10.

Der Körper 10 besteht aus einer inneren und einer äußeren Hülse 25, 26, zwischen denen ein Ringkanal 27 ausgebildet ist, der mit dem Versorgungskanal .12 in Verbindung steht* Dieser Ringkanal 27 weist an seinem Austrittsende eine Stirnwand 28 auf, die mit öffnungen 29 versehen ist, deren Achsen im wesentlichen parallel zur Achse des Körpers 10 verlaufen.The body 10 consists of an inner and an outer sleeve 25, 26, between which an annular channel 27 is formed is, which is connected to the supply channel .12 * This annular channel 27 has an end wall at its outlet end 28, which is provided with openings 29, the axes of which run essentially parallel to the axis of the body 10.

Am Austrittsende des Körpers 10 ist eine nach innen gerichtete, ringförmige Rippe 30 angeordnet s auf die der aus den Öffnungen 29 austretende Brennstoff auf trifft,, bevor er von dem Luftstrom der Dralleinrichtung 13 fortgetragen wird.Is at the outlet end of the body 10 an inwardly directed, annular rib 30 s arranged on the emerging from the openings 29 on fuel meets ,, before it is carried away by the air stream of the swirl device. 13

In der Ausführungsform nach Fig. 2 ist die Dralleinrichtung 33 innerhalb einer konvergierenden" Düse 3^ angeordnet. Im übrigen entspricht diese Ausführungsform der nach Pig. I;In the embodiment according to FIG. 2, the swirl device 33 is arranged within a converging “nozzle 3 ^ Otherwise, this embodiment corresponds to that according to Pig. I;

Die beiden oben beschriebenen Ausführungsformen der erfin« dungsgemäßen Vorrichtung gewährleisten eine wirksame Zerstäubung des Brennstoffs über einen weiten Bereich sowohl des Brennstoffdrucks als auch der Mischluftgeschwindigkeit. Dieses ist von besonderer Bedeutung bei der Verwendung der Vorrichtung in einer Gasturbine, da beim Anlassen der Turbine sehr niedrige Brennstoffdrücke und Luftdrücke vorhanden sind. Nach dem Anlassen erhöht sich mit der Drehzahl der Turbine auch der Brennstoff- und Luftdruck* so daß auch in diesem Bereich eine wirksame Zerstäubung der erfindungsgemäßen Vorrichtung gewährleistet sein mußcThe two embodiments of the device according to the invention described above ensure effective atomization of the fuel over a wide range of both the fuel pressure and the mixed air velocity. This is of particular importance when the device is used in a gas turbine , since very low fuel pressures and air pressures are present when the turbine is started. After starting, the speed of the turbine increases the fuel and air pressure * so that effective atomization of the device according to the invention must also be ensured in this area
