Definitions
- the invention relates to a burner for liquid fuels according to the preamble of claim 1.
- a generic burner is for example from the EP 0 683 883 B1 known. It consists of a burner housing, which has a support tube with an arranged in this prechamber and an adjoining flame tube. In the support tube, a nozzle with a fuel jet nozzle is arranged in the prechamber, and in the flame tube, the fuel jet spreads. Between the pre-chamber and the combustion chamber is a diaphragm with a central opening through which the fuel jet passes through, as well as additional openings on a more outer pitch circle.
- combustion air flow is generated.
- This includes a partial stream close to the fuel stream and a recirculation-stabilizing partial stream.
- the flame tube is provided with recirculation openings for cooled flue gas, which are mounted in particular in the jacket in the area in front of the panel.
- the radially outer recirculation-stabilizing partial flow has the form of a flow pattern corresponding to an annular flow interrupted in the circumferential direction, so that an inner recirculation flow running back from the blue-burning flame to the non-burning part of the fuel jet is formed in the combustion chamber.
- the recirculation-stabilizing partial flow of the combustion air favors the inner recirculation flow.
- the disclosure DE 38 01 681 C1 a method of combusting a gaseous or liquid fuel having a multi-hole orifice surrounding the outlet of a nozzle, the combustion air jets of which open into an axially extending mixing tube within the flame tube.
- the mixing tube has recesses around it to produce so-called internal recirculation between mixing tube and flame tube.
- such a mixing tube in the direct jet or flame area also cause undesirable flow noise.
- the invention is therefore based on the object to optimize the combustion quality and robustness in different operating conditions in a burner for liquid fuels.
- the burner for liquid fuels is characterized in that the diaphragm has a central opening with a plurality of extensions which extend fan-shaped in the radial direction from a fuel-jet-proximate core region.
- the combustion air enters the combustion chamber in conjunction with the fuel jet near the core stream, also in a bypass flow emanating therefrom.
- This sheath flow is fan-shaped, lies radially outside the core flow and stabilizes the inner recirculation flow of the hot gases.
- the flow pattern of the coherent combustion air flow emerging through the central opening in the diaphragm corresponds approximately to the shape of a polygonal profile in cross section.
- a further internal recirculation flow is generated, which forms in each case between two adjacent compartments of the sheath flow.
- the central opening is formed point-symmetrical to the nozzle and the fan-shaped extensions are evenly distributed over the circumference and around the core area near the fuel path.
- the central opening has five to ten fan-shaped extensions.
- the fan-shaped extensions each consist of a slot which communicates with the end face facing the fuel jet near the core area in connection with the center.
- the width of an elongated hole corresponds approximately to half its length and the length is approximately equal to the diameter of the fuel jet near the core region in the central opening.
- fan-shaped sheath flow have the fan-shaped
- Each extension has a smaller width. This constriction preferably extends for about a quarter to a third of the total length of an extension.
- both the combustion quality and the robustness in different operating states are optimized in a burner for liquid fuels.
- the orifice is still flowed through axially and, as in known burners, an internal recirculation is produced between the core stream and the flame tube wall which is characteristic of burners having a blue burning flame. But to stabilize the flame, this would not be enough on its own. Therefore, a second inner recirculation flow is generated with the fan-shaped in the radial direction of the fuel jet near the core stream extending extensions, which forms each between two adjacent compartments of the sheath current.
- the flow pattern of the coherent combustion air flow emerging through the central opening in the diaphragm is similar in cross-section to the shape of a polygonal profile.
- the mixing device of the burner for liquid fuels consists of a flame tube 1, which surrounds a combustion chamber 2, in which a fuel jet from a nozzle propagates. This is upstream of the combustion chamber 2, mounted just behind a panel 3.
- the combustion air flow generated by a blower passes through a central Opening 4 in the aperture 3 therethrough. From the fuel-near-core region of this opening 4 go out several, extending in the radial direction, fan-shaped extensions 5. As a result, the combustion air is broken down into a fan-shaped, radially outer jacket flow, which stabilizes the inner recirculation flow of the hot gases, in conjunction with the fuel jet near the core stream.
- a constriction 6 is provided and in the flame tube 1 are still openings 7 for an external recirculation of cooled flue gases from the surrounding furnace into the combustion chamber.
Abstract
Description
Die Erfindung betrifft einen Brenner für flüssige Brennstoffe nach dem Oberbegriff des Patentanspruches 1.The invention relates to a burner for liquid fuels according to the preamble of
Ein gattungsgemäßer Brenner ist beispielsweise aus der
Mit einem Gebläse wird der in die Brennkammer eintretende Verbrennungsluftstrom erzeugt. Dieser umfasst einen brennstoffstrahinahen Teilstrom sowie einen rezirkulationsstabilisierenden Teilstrom. Dazu ist das Flammrohr mit Rezirkulationsöffnungen für ausgekühltes Rauchgas versehen, welche insbesondere in dessen Mantel im Bereich vor der Blende angebracht sind. Der radial außen liegende rezirkulationsstabilisierende Teilstrom besitzt die Form eines einem in Umfangsrichtung unterbrochenen Ringstromes entsprechenden Strömungsbildes, so dass sich in der Brennkammer eine von der blau brennenden Flamme zum nicht brennenden Teil des Brennstoffstrahls zurück verlaufende innere Rezirkulationsströmung ausbildet. Außerdem begünstigt der rezirkulationsstabilisierende Teilstrom der Brennluft die innere Rezirkulationsströmung. Je nach Brennkammergeometrie und Betriebszustand bestand aber bei der Blendengestaltung mit einem zentralen Kernloch und zusätzlichen, separaten Durchbrechungen auf einem weiter außen liegenden Teilkreis die Möglichkeit, dass sich Ablagerungen auf der Blende bildeten oder das Startverhalten nicht optimal war.With a blower entering the combustion chamber combustion air flow is generated. This includes a partial stream close to the fuel stream and a recirculation-stabilizing partial stream. For this purpose, the flame tube is provided with recirculation openings for cooled flue gas, which are mounted in particular in the jacket in the area in front of the panel. The radially outer recirculation-stabilizing partial flow has the form of a flow pattern corresponding to an annular flow interrupted in the circumferential direction, so that an inner recirculation flow running back from the blue-burning flame to the non-burning part of the fuel jet is formed in the combustion chamber. In addition, the recirculation-stabilizing partial flow of the combustion air favors the inner recirculation flow. Depending on the combustion chamber geometry and operating state, however, there was the possibility in the diaphragm design with a central core hole and additional, separate openings on a further outer circle that deposits formed on the diaphragm or the starting behavior was not optimal.

Der Erfindung liegt daher die Aufgabe zugrunde, bei einem Brenner für flüssige Brennstoffe die Verbrennungsqualität und die Robustheit in unterschiedlichen Betriebszuständen zu optimieren.The invention is therefore based on the object to optimize the combustion quality and robustness in different operating conditions in a burner for liquid fuels.
Erfindungsgemäß wurde dies mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.This has been achieved with the features of
Der Brenner für flüssige Brennstoffe ist dadurch gekennzeichnet, dass die Blende eine zentrale Öffnung mit mehreren, in radialer Richtung fächerförmig von einem brennstoffstrahlnahen Kernbereich ausgehenden Fortsätzen besitzt. Dadurch tritt die Verbrennungsluft in Verbindung mit dem brennstoffstrahlnahen Kernstrom, auch in einem von diesem ausgehenden Mantelstrom in die Brennkammer ein. Dieser Mantelstrom verläuft fächerförmig, liegt radial außerhalb des Kernstromes und stabilisiert die innere Rezirkulationsströmung der Heizgase.The burner for liquid fuels is characterized in that the diaphragm has a central opening with a plurality of extensions which extend fan-shaped in the radial direction from a fuel-jet-proximate core region. As a result, the combustion air enters the combustion chamber in conjunction with the fuel jet near the core stream, also in a bypass flow emanating therefrom. This sheath flow is fan-shaped, lies radially outside the core flow and stabilizes the inner recirculation flow of the hot gases.
Dabei entspricht das Strömungsbild des durch die zentrale Öffnung in der Blende austretenden, zusammenhängenden Verbrennungsluftstromes im Querschnitt etwa der Form eines Polygonprofils. Zusätzlich zur inneren Rezirkulation zwischen dem Kernstrom und der Wand des Flammrohres wird eine weitere innere Rezirkulationsströmung erzeugt, welche sich jeweils zwischen zwei benachbarten Fächern des Mantelstromes ausbildet.In this case, the flow pattern of the coherent combustion air flow emerging through the central opening in the diaphragm corresponds approximately to the shape of a polygonal profile in cross section. In addition to the internal recirculation between the core stream and the wall of the flame tube, a further internal recirculation flow is generated, which forms in each case between two adjacent compartments of the sheath flow.
Die zentrale Öffnung ist punktsymmetrisch zur Düse ausgebildet und die fächerförmigen Fortsätze sind gleichmäßig über den Umfang und um den brennstoffstrahinahen Kernbereich verteilt. Vorzugsweise besitzt die zentrale Öffnung fünf bis zehn fächerförmige Fortsätze. Dabei bestehen die fächerförmigen Fortsätze jeweils aus einem Langloch, welches zum Zentrum hin mit einer Stirnseite mit dem brennstoffstrahlnahen Kernbereich in Verbindung steht. Die Breite eines Langloches entspricht etwa dessen halber Länge und die Länge gleicht etwa dem Durchmesser des brennstoffstrahlnahen Kernbereiches in der zentralen Öffnung. Im Verbindungsbereich zwischen dem brennstoffstrahinahen Kernstrom und dem von diesem ausgehenden, fächerförmigen Mantelstrom weisen die fächerförmigen Fortsätze jeweils eine geringere Breite auf. Diese Einschnürung erstreckt sich vorzugsweise etwa über ein Viertel bis ein Drittel der Gesamtlänge eines Fortsatzes.The central opening is formed point-symmetrical to the nozzle and the fan-shaped extensions are evenly distributed over the circumference and around the core area near the fuel path. Preferably, the central opening has five to ten fan-shaped extensions. In this case, the fan-shaped extensions each consist of a slot which communicates with the end face facing the fuel jet near the core area in connection with the center. The width of an elongated hole corresponds approximately to half its length and the length is approximately equal to the diameter of the fuel jet near the core region in the central opening. In the connecting region between the fuel stream near core stream and the outgoing from this, fan-shaped sheath flow have the fan-shaped Each extension has a smaller width. This constriction preferably extends for about a quarter to a third of the total length of an extension.
Es hat sich als vorteilhaft erwiesen, wenn der durch die Blende hindurch tretende Verbrennungsluftvolumenstrom sowie die freien Durchströmquerschnitte der zentralen Öffnung zu etwa bis 15 bis 60 % auf den brennstoffstrahlnahen Kernstrom und zu etwa 40 bis 85 % auf den fächerförmigen, die innere Rezirkulationsströmung stabilisierenden Mantelstrom aufgeteilt werden.It has proven to be advantageous if the passing through the aperture combustion air flow rate and the free flow areas of the central opening to about 15 to 60% split on the fuel jet near core stream and about 40 to 85% on the fan-shaped, the inner recirculation flow stabilizing jacket flow become.
Mit den erfindungsgemäßen Maßnahmen werden bei einem Brenner für flüssige Brennstoffe sowohl die Verbrennungsqualität und als auch die Robustheit in unterschiedlichen Betriebszuständen optimiert. Die Blende wird weiterhin axial durchströmt, und es wird wie bei bekannten Brennern eine innere Rezirkulation zwischen dem Kernstrom und der Flammrohrwand erzeugt, welche charakteristisch für Brenner mit einer blau brennenden Flamme ist. Zur Stabilisierung der Flamme wäre dies aber alleine nicht ausreichend. Daher wird mit den fächerförmig in radialer Richtung vom brennstoffstrahlnahen Kernstrom ausgehenden Fortsätzen eine zweite innere Rezirkulationsströmung erzeugt, welche sich jeweils zwischen zwei benachbarten Fächern des Mantelstromes ausbildet. Somit ähnelt das Strömungsbild des durch die zentrale Öffnung in der Blende austretenden, zusammenhängenden Verbrennungsluftstromes erfindungsgemäß im Querschnitt der Form eines Polygonprofils.With the measures according to the invention, both the combustion quality and the robustness in different operating states are optimized in a burner for liquid fuels. The orifice is still flowed through axially and, as in known burners, an internal recirculation is produced between the core stream and the flame tube wall which is characteristic of burners having a blue burning flame. But to stabilize the flame, this would not be enough on its own. Therefore, a second inner recirculation flow is generated with the fan-shaped in the radial direction of the fuel jet near the core stream extending extensions, which forms each between two adjacent compartments of the sheath current. Thus, according to the invention, the flow pattern of the coherent combustion air flow emerging through the central opening in the diaphragm is similar in cross-section to the shape of a polygonal profile.
