Abstract
Description
Die Erfindung betrifft eine mit Luftunterstützung arbeitende Kraftstoffdüse, insbesondere solche in Gasturbinen für stationäre Gleichdruckverbrennung.The invention relates to a working with air assistance Fuel nozzle, especially those in gas turbines for stationary constant pressure combustion.
Eine derartige Kraftstoffdüse als luftgestützter Direkt zerstäuber ist aus der 1980 erschienenen Druckschrift "The Design and Development of Gas Turbine Combustors" Volume I Component Theory and Practice, Northern Research and Engineering Corporation, Woburn, Massachusetts, U.S.A., Seite 6.65, Fig. 6.19 - Airblast Atomizer - Pintle Type, bekannt.Such a fuel nozzle as an air-based direct atomizer is from the publication "The Design and Development of Gas Turbine Combustors" published in 1980 Volume I Component Theory and Practice, Northern Research and Engineering Corporation, Woburn, Massachusetts, USA, page 6.65, Fig. 6.19 - Airblast Atomizer - Pintle Type, known.
In dieser Kraftstoffdüse wird im inneren Luftkanal ein Flüssigkeitsfilm gebildet, von einem Luftstrom zur ring förmigen Zerstäubungskante am Außenkörper der Düse ge trieben und dort unter Mitwirkung eines zweiten Luft stromes zerstäubt. Die luftgestützte Kraftstoffdüse ermöglicht eine gezielte Beeinflussung der räumlichen Brennstoffverteilung und eine gute Regelbarkeit, da die Zerstäubungsgüte nicht mehr wie bei Druckzerstäubern vom Flüssigkeitsdurchsatz abhängt.In this fuel nozzle in the inner air duct Liquid film formed from an air flow to the ring shaped atomizing edge on the outer body of the nozzle ge driven and there with the participation of a second air stream atomized. The air-based fuel nozzle enables a targeted influencing of the spatial Fuel distribution and good controllability as the Atomization quality no longer as with pressure atomizers from Liquid flow rate depends.
Begrenzend wirken sich bei diesem Zerstäubertyp die Stabilitätsgrenzen des Flüssigkeitsfilms aus, der sich bei zu kleinen Durchsätzen in Strähnen auflöst und bei zu großen Volumenströmen schon vor der Zerstäubungskante Tropfen absondert. Außerdem ist eine Benetzung der gegen überliegenden Wand kaum zu vermeiden, die zu unkontrollier baren Vorgängen wie Pfropfenströmung im Luftkanal und Ab tropfen von der nicht vollständig von Luft umspülten Außenwand zur Folge hat. Außerdem verhindert die Trägheit des Flüssigkeitsfilms einen Einsatz im echt instationären Betrieb, wie er bei der motorischen Verbrennung ge fordert wird.This atomizer has a limiting effect Stability limits of the liquid film from the dissolves in strands if the throughput is too low and at too large volume flows before the atomizing edge Drops separate. In addition, wetting the against overlying wall hard to avoid being too uncontrolled processes such as plug flow in the air duct and Ab drip from the not completely flushed with air Outside wall. It also prevents sluggishness of the liquid film is used in a truly unsteady state Operation as it is in engine combustion is requested.
Die geschilderten Nachteile durch einfache konstruktive Maßnahmen an einer luftgestützten Kraftstoffdüse zu be seitigen, ist Aufgabe der vorliegenden Erfindung.The disadvantages described by simple constructive Measures to be taken on an air-based fuel nozzle sided, is the object of the present invention.
Zur Lösung dieser Aufgabe dienen die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale.To solve this problem, the in the characteristics of Features specified claim 1.
Durch die Herausnahme des Flüssigkeitsfilms aus dem Luftkanal lassen sich extrem enge Luftspalte (bis unter 0,15 mm) verwirklichen, die entsprechend kleine Flächen belastungen und Luftverbräuche erlauben. Somit brauchen die seither schwer in den Griff zu bekommenden Stabilitäts grenzen des Flüssigkeitsfilms nicht mehr eingehalten zu werden. Die Kraftstoffdüse eignet sich deshalb insbe sondere bei kleinen Flächenbelastungen für eine gleich bleibend gute Zerstäubung bei verringertem Luftverbrauch und Druckverlust und gleichzeitig verbesserter Regelbar keit des Kraftstoffdurchsatzes.By removing the liquid film from the Air duct can be extremely narrow air gaps (up under 0.15 mm) realize the correspondingly small areas allow loads and air consumption. So need the stability that has been difficult to control since then limits of the liquid film are no longer adhered to will. The fuel nozzle is therefore particularly suitable especially with small wing loads for the same consistently good atomization with reduced air consumption and pressure loss and at the same time improved controllability fuel flow rate.
In den Unteransprüchen sind vorteilhafte und förderliche Weiterbildungen angegeben.In the subclaims are advantageous and beneficial Further training specified.
Um den Druckverlust der Luftströmung zu reduzieren und ein feineres Tropfenspektrum zu erzeugen, ist die Luft strömung erst am Düsenaustritt bzw. an der Zerstäubungs kante durch eine konvergente Kanalkontur auf ihre End geschwindigkeit zu beschleunigen (Anspruch 4). Ist der Winkel zwischen den äußeren Luftkanalwänden groß genug, so wird zusätzlich eine Einschnürung der Strömung hinter dem Kanalaustritt in der Nähe des Zerfallpunktes hervor gerufen, wodurch eine weitere Verringerung des effektiven Strömungsquerschnittes noch unter den Wert der konstruktiv vorgegebenen Austrittsspalte möglich ist.To reduce the pressure drop in the air flow and The air is to produce a finer drop spectrum Flow only at the nozzle outlet or at the atomization edge through a convergent channel contour to its end accelerate speed (claim 4). Is the Angle between the outer air duct walls large enough so the flow is also constricted behind the channel exit near the decay point called, causing a further reduction in the effective Flow cross section still below the value of the constructive predetermined exit column is possible.
Durch eine Verdrallung der Zerstäubungsluft wird die Axialkomponente der Luftgeschwindigkeit und damit der Volumenstrom nochmals verringert und gleichzeitig werden die Scherkräfte am Düsenaustritt zugunsten einer besseren Zerstäubung verstärkt (Ansprüche 5 und 6). Werden die tangential zugeführten Luftströme gegensinnig verdrallt, ergibt sich eine weitere Verbesserung der Zerstäubungsgüte.By swirling the atomizing air, the Axial component of the air speed and thus the Volume flow again reduced and at the same time the shear forces at the nozzle outlet in favor of a better one Atomization increased (claims 5 and 6). Will the tangentially fed air flows are twisted in opposite directions, there is a further improvement in the atomization quality.
Die im Düsenendbereich den Kraftstoffdurchlaß bestimmenden Bohrungen (Anspruch 7) können in ihrer Anzahl variierbar sein, das bedeutet, daß zur Bereichserweiterung Gruppen schaltungen bestimmter Bohrungen durch externe Vorgaben oder mittels einer internen Selbstregelung, z.B. über den Flüssigkeitsvordruck, möglich sind. Those determining the fuel passage in the nozzle end area Holes (claim 7) can be varied in number be, that means that to expand the area groups switching of certain holes through external specifications or by means of an internal self-regulation, e.g. about the liquid pre-pressure are possible.
Zum Ausgleich von Störeinflüssen kann eine gezielte Vor drosselung der Flüssigkeit vorgesehen sein (Anspruch 8).To compensate for interferences, a targeted pre throttling of the liquid can be provided (claim 8).
Die Kraftstoffdüse kann je nach Verwendungszwecke auch als Flachdüse ausgebildet sein.The fuel nozzle can also be used depending on the purposes be designed as a flat nozzle.

Radially extending and opposite air supply bores 16 , 17 are arranged in the outer body 2 , which open out tangentially into the annular space 6 .
Der äußere Luftkanal 7 bildet ebenfalls einen als Drall raum wirkenden Ringraum mit zunächst gleichbleibendem Querschnitt und zum Düsenaustritt hin sich verkleinerndem Querschnitt. In diesem Bereich verjüngt sich der Aus nehmungsabschnitt 9 b, während die Außenwand 11 des Ring körpers 5 zylindrischen Verlauf hat. Auch in diesen äußeren Ringraum münden radial im Außenkörper 2 ver laufende Luftzuführbohrungen 18, 19 tangential ein, die einander gegenüberliegen.
