- the additional channel can largely be designed as desired and in sections from a large number of interacting individual channels (e.g. holes) exist.
- the gas admixture near the atomizer edge ensures a homogeneous mixing of the fuel components with sufficient Cooling of the burner - without the flame front retracting the air ducts.
- a burner arrangement that can be operated with either liquid or gaseous fuel is already known from DE 28 20 702 C2. This points in Center a mixing ring with a mixing surface, which with a Airflow a spray of liquid fuel can be supplied and from which the fuel-air mixture enters the mixing ring. Gaseous fuel can be introduced into an air stream from the underside of the mixing ring. It is not planned to operate both fuels together.
- the two-fuel burner 1, the longitudinal center axis of which is designated X, is fed with liquid fuel F via the atomizing nozzle 2.
- the fuel emerges from the atomizing nozzle 2 in the form of a divergent spray cone 13 and meets the inner surface of an annular one concentric with respect to the X axis Atomizer lip 3.
- a downstream migrating lip forms on this Fuel film 14, which on the atomizer edge 4 as a result of there prevailing air flow conditions in a fine, air-permeable Fuel mist 15 is transformed.
- the combustion air is in the form of two initially separate air flows L1 and L2 through the dual fuel burner 1.
- the first airflow L1 arrives via a primary, central channel 5 through the spray cone area as the core flow to the atomizer edge 4 of the atomizer lip 3.
- the second air flow L2 passes through a secondary, concentric channel 6 over the outer circumference the atomizer lip 3 to the atomizer edge 4, where it is on as a sheath flow hits the first air flow L1 and the liquid fuel.
- the convergent-divergent Outer contour 10 of the secondary channel 6 with a narrowest cross section in the area of the atomizer edge 4 leads to flow conditions there, which promote the homogenization of the fuel-air mixture.
- the swirl generator 8.9 can the currents in the channels 5 and 6th swirling movements in the same or opposite directions, i.e. Components in the circumferential direction be imprinted.
- the two air flows L1 meet and L2 on the atomizer edge 4 result in speed differences in size and direction and circumferential components to shear and centrifugal forces, with their Help an intimate mixing of fuel and air can be achieved.

Description
Die Erfindung betrifft einen Brenner für die Oxidation von flüssigem Brennstoff
mit Luft, gemäß dem Oberbegriff des Patentanspruches 1, in Ausbildung als
Zweistoffbrenner.The invention relates to a burner for the oxidation of liquid fuel
with air, according to the preamble of
Ein gattungsgemäßer, für Einstoffbetrieb mit flüssigem Brennstoff ausgelegter Brenner ist aus der DE 196 27 760 A1 bekannt. Dieses Brennerkonzept dient der weitgehend homogenen Verteilung eines Luftbrennstoffgemisches im Brennraum zur Reduktion von Schadstoffemissionen. Dabei ist der divergente Spritzkegel einer Zerstäuberdüse auf eine als Prallkörper wirkende Zerstäuberlippe gerichtet, auf deren Innenseite sich ein stromabwärts bewegender Brennstoffilm bildet. Der Brennstoffilm wandert bis zu einer Zerstäuberkante am hinteren Ende der Zerstäuberlippe, wo er durch eine Luftführung mit zwei sich vereinigenden Luftströmen (primär und sekundär) sowie eine lokale Querschnittsverengung hohen Scherkräften unterliegt und dadurch besonders fein und homogen zerstäubt wird. Die bevorzugte Anwendung dieser Brenner erfolgt in mit Kerosin betriebenen Fluggasturbinen.A generic one, designed for single-fuel operation with liquid fuel Brenner is known from DE 196 27 760 A1. This burner concept serves the largely homogeneous distribution of an air fuel mixture in the Combustion chamber to reduce pollutant emissions. Here is the divergent Spray cone of an atomizer nozzle on an atomizer lip acting as a baffle directed, on the inside of which a downstream moving Fuel film forms. The fuel film travels to an atomizer edge at the rear end of the nebulizer lip, where it passes through an air duct with two unifying air flows (primary and secondary) and a local cross-sectional narrowing subject to high shear forces and therefore particularly fine and is atomized homogeneously. These burners are preferred for use in kerosene-powered aircraft gas turbines.
Aus der DE 195 39 246 A1 ist auch einen solcher Brenner bekannt.Such a burner is also known from DE 195 39 246 A1.
Bei stationären Gasturbinen, welche als schnell zu- und abschaltbare Kraftmaschinen hoher Leistung in zunehmendem Maße in Kraftwerken zur Stromerzeugung (Spitzenlast) verwendet werden, wird im Hinblick auf eine uneingeschränkte Einsatzbereitschaft vermehrt die Eignung für Betrieb mit gasförmigem und mit flüssigem Brennstoff gefordert. Für den "normalen" Betrieb ist beispielsweise Erdgas, für einen "Notbetrieb" leichtes Heizöl vorgesehen. Dabei können auch Betriebszustände auftreten bzw. vorgesehen sein, in denen beide Brennstoffe gleichzeitig eingespeist werden. Abgesehen von dieser speziellen Anwendung kann der "Zweistoffbetrieb" bzw. die Eignung hierfür bei verschiedenen Brenneranwendungen Vorteile bieten. In the case of stationary gas turbines, which can be switched on and off quickly as power machines high performance increasingly in power plants for power generation (Peak load) is used with regard to an unrestricted Operational readiness increases the suitability for operation with gaseous and required with liquid fuel. For "normal" operation is for example natural gas, light heating oil intended for "emergency operation". there Operating states can also occur or be provided in which both fuels can be fed in simultaneously. Aside from this special Application can the "two-substance operation" or the suitability for this offer advantages for different burner applications.
Daher besteht die Aufgabe der Erfindung darin, einen Brenner gattungsgemäßer so Art zu erweitern, daß er unter Beibehaltung seiner positiven Brenneigenschaften für einen Betrieb mit flüssigem und mit gasförmigem Brennstoff geeignet ist.Therefore, the object of the invention is a burner of the generic type so kind of expanding that it while maintaining its positive burning properties for operation with liquid and gaseous fuel suitable is.
Diese Aufgabe wird durch die im Anspruch 1 gekennzeichneten Merkmale gelöst,
in Verbindung mit den gattungsbildenden Merkmalen in dessen Oberbegriff.This object is achieved by the features characterized in
Die Unteransprüche kennzeichnen bevorzugte Ausgestaltungen des Zweistoffbrenners nach dem Hauptanspruch.The subclaims characterize preferred configurations of the two-fuel burner according to the main claim.
Die erfindungsgemäße Lösung besteht darin, daß ein zusätzlicher Kanal für den gasförmigen Brennstoff in das Innere der Zerstäuberlippe geführt ist und stromaufwärts der Zerstäuberkante, also der für die Brennstoffaufbereitung letztlich maßgeblichen Stelle, in den primären und/oder in den sekundären Kanal mündet. Der zusätzliche Kanal kann weitgehend beliebig gestaltet sein und abschnittsweise aus einer Vielzahl von zusammenwirkenden Einzelkanälen (z.B. Bohrungen) bestehen. Die Gaszumischung nahe der Zerstäuberkante gewährleistet eine homogene Durchmischung der Brennkomponenten bei ausreichender Kühlung des Brenners -ohne ein Zurückschlagen der Flammenfront in die Luftkanäle.The solution according to the invention is that an additional channel for the gaseous fuel is led into the interior of the atomizer lip and upstream of the atomizer edge, i.e. that for fuel processing ultimately authoritative position, in the primary and / or in the secondary Canal opens. The additional channel can largely be designed as desired and in sections from a large number of interacting individual channels (e.g. holes) exist. The gas admixture near the atomizer edge ensures a homogeneous mixing of the fuel components with sufficient Cooling of the burner - without the flame front retracting the air ducts.
Eine wahlweise mit flüssigem oder gasförmigem Brennstoff betreibbare Brenneranordnung ist bereits aus der DE 28 20 702 C2 bekannt. Diese weist im Zentrum einen Mischungsring mit einer Mischfläche auf, welcher mit einem Luftstrom ein Sprühnebel flüssigen Brennstoffs zuführbar ist und von welcher das Brennstoff-Luft-Gemisch in den Mischungsring eintritt. Gasförmiger Brennstoff ist von der Unterseite des Mischungsringes her in einen Luftstrom einleitbar. Ein gemeinsamer Betrieb beider Brennstoffe ist nicht vorgesehen. A burner arrangement that can be operated with either liquid or gaseous fuel is already known from DE 28 20 702 C2. This points in Center a mixing ring with a mixing surface, which with a Airflow a spray of liquid fuel can be supplied and from which the fuel-air mixture enters the mixing ring. Gaseous fuel can be introduced into an air stream from the underside of the mixing ring. It is not planned to operate both fuels together.
Die Erfindung wird anschließend anhand der Figur noch näher erläutert. Diese zeigt in vereinfachter, nicht maßstäblicher Darstellung zwei in übereinanderliegenden, durch die Brennerachse getrennten Halbschnitten wiedergegebene Brennervarianten mit unterschiedlicher Gaszumischung.The invention is subsequently explained in more detail with reference to the figure. This shows in a simplified, not to scale representation two in superimposed, half sections reproduced by the burner axis Burner variants with different gas admixtures.
Der Zweistoffbrenner 1, dessen Längsmittelachse mit X bezeichnet ist, wird
über die Zerstäuberdüse 2 mit flüssigem Brennstoff F gespeist. Der Brennstoff
tritt aus der Zerstäuberdüse 2 in Form eines divergenten Spritzkegels 13 aus
und trifft auf die Innenfläche einer bezüglich der Achse X konzentrischen, ringförmigen
Zerstäuberlippe 3. Auf dieser bildet sich ein stromabwärts wandernder
Brennstoffilm 14 aus, welcher an der Zerstäuberkante 4 infolge der dort
herrschenden Luftströmungsverhältnisse in einen feinen, luftdurchsetzten
Brennstoffnebel 15 verwandelt wird.The two-
Die Verbrennungsluft wird in Form zweier, zunächst getrennter Luftströme L1
und L2 durch den Zweistoffbrenner 1 geführt. Der erste Luftstrom L1 gelangt
über einen primären, zentralen Kanal 5 durch den Spritzkegelbereich als Kernstrom
zur Zerstäuberkante 4 der Zerstäuberlippe 3. Der zweite Luftstrom L2
gelangt durch einen sekundären, konzentrischen Kanal 6 über den Außenumfang
der Zerstäuberlippe 3 zur Zerstäuberkante 4, wo er als Mantelstrom auf
den ersten Luftstrom L1 sowie den flüssigen Brennstoff trifft. Die konvergent-divergente
Außenkontur 10 des sekundären Kanals 6 mit einem engsten Querschnitt
im Bereich der Zerstäuberkante 4 führt dort zu Strömungsverhältnissen,
welche die Homogenisierung des Brennstoff-Luft-Gemisches fördern. Mittels
der Drallerzeuger 8,9 können den Strömungen in den Kanälen 5 und 6
gleich- oder gegensinnige Drallbewegungen, d.h. Komponenten in Umfangsrichtung
aufgeprägt werden. Beim Zusammentreffen der beiden Luftströme L1
und L2 an der Zerstäuberkante 4 führen Geschwindigkeitsdifferenzen in Größe
und Richtung sowie Umfangskomponenten zu Scher- und Fliehkräften, mit deren
Hilfe sich eine innige Durchmischung von Brennstoff und Luft erzielen läßt.
Dabei möchte man den Brennstoff auf einer möglichst kurzen axialen Mischstrecke
in möglichst kleine, homogen verteilte Tröpfchen mit großer oxidierbarer
Gesamtoberfläche umsetzen, wobei die Gemischzone sich ebenfalls auf
möglichst kurzem, axialem Weg auf einen vorgegebenen Querschnitt, insbesondere
den Brennkammerquerschnitt, erweitern sollte, d.h. stark divergieren
sollte.The combustion air is in the form of two initially separate air flows L1
and L2 through the
Bis hierher beziehen sich die Ausführungen auf die Aufbereitung des flüssigen Brennstoffes.So far, the explanations refer to the preparation of the liquid Fuel.
Für den gasförmigen Brennstoff G ist ein zusätzlicher Kanal 7 vorgesehen, welcher
zwischen den Kanälen 5 und 6 der Verbrennungsluft separat in das Innere
der Zerstäuberlippe 3 führt. Von dort wird der gasförmige Brennstoff über
Strömungsverbindungen stromaufwärts der Zerstäuberkante 4 in den primären
Kanal 5, in den sekundären Kanal 6 oder in beide Kanäle 5,6 geleitet, d.h. mit
Luft und ggf. auch mit flüssigem Brennstoff zusammengeführt. Dabei nimmt
auch der gasförmige Brennstoff an dem bei der Zerstäuberkante 4 initiierten
Verteilungsprozeß teil.An
Falls der Zweistoffbrenner 1 zeitlich getrennt entweder mit Flüssigbrennstoff
oder mit Gas betrieben werden soll, werden der gasförmige Brennstoff wie der
flüssige Brennstoff in den primären, zentralen Kanal 5 geleitet. Die konstruktiven
Gegebenheiten hierfür sind im Halbschnitt oberhalb der Achse X wiedergegeben.
Man erkennt, daß eine zusammenhängende, ringförmige Öffnung auf
der Innenseite der Zerstäuberlippe 3 die Mündung des Kanals 7 bildet. Ebensogut
könnte eine Vielzahl von Bohrungen diese Mündung bilden. Der Gasaustritt
erfolgt also dort, wo sich im Flüssigkeitsbetrieb der Brennstoffilm 14 in
Richtung Zerstäuberkante 4 bewegt. Da durch die gewählte Betriebsweise
(alternativ) keine Wechselwirkung Flüssigbrennstoff/Gas auftritt, ist dies praktisch
ohne Belang. If the two-
Anders liegen die Verhältnisse bei gleichzeitigem, d.h. kombiniertem, Betrieb
mit Flüssigbrennstoff und Gas. Die hierfür gedachte Bauweise ist im Halbschnitt
unterhalb der Achse X dargestellt. Da es nachteilig sein kann, den
Brennstoffilm 14 (flüssig) durch die Gaszufuhr großteils bis vollständig zu zerstören,
bevor dieser die Zerstäuberkante 4 erreicht, ist vorgesehen, den gasförmigen
Brennstoff teilweise oder ausschließlich in den sekundären, von flüssigem
Brennstoff freien Kanal 6 zu leiten. Hierfür sind durch die Außenwand
der Zerstäuberlippe 3 stoßende Bohrungen 11 geeignet. Zusätzlich können
Bohrungen 12 (gestrichelt) oder andere Öffnungen vorhanden sein, welche
einen Teil des gasförmigen Brennstoffstromes durch den flüssigen Brennstoffilm
hindurch freisetzen.The situation is different with simultaneous, i.e. combined, operation
with liquid fuel and gas. The construction intended for this is in half section
shown below the X axis. Since it can be disadvantageous
To destroy fuel film 14 (liquid) largely to completely by the gas supply,
before it reaches the
An dieser Stelle sei darauf hingewiesen, daß der flüssige Brennstoffilm 14 auf
der Zerstäuberlippenoberfläche auch eine wichtige Kühlfunktion ausübt. Deshalb
kann es angebracht sein, das Gas an mehreren, lokal eng begrenzten
Stellen durch den Brennstoffilm 14 zu leiten, so daß zwischen diesen Stellen
ausreichend große, ungestörte Filmzonen verbleiben.At this point it should be noted that the
