Abstract
Description
Die Erfindung richtet sich auf einen Gasbrenner, insbesondere atmosphärischer Gasbrenner mit Primärluftvormischung, mit einem Gasaustrittskanäle aufweisenden Brennerring und mit einem ggf. damit einstückig ausgebildeten Brennerdeckel, wobei die Mittelachse der Gasaustrittskanäle einen von 0° abweichenden Winkel zu einem der jeweiligen Austrittsöffnung zugeordneten Radius aufweist.The invention relates to a gas burner, in particular an atmospheric gas burner with primary air premixing, with a burner ring having gas outlet channels and with a burner cover which may be formed in one piece therewith, the central axis of the gas outlet channels having an angle deviating from 0 ° to a radius assigned to the respective outlet opening.
Gasbrenner für Herde sind in verschiedenen Ausführungen bekannt. Dabei weisen die bekannten Brenner Flammenaustrittsöffnungen, die als Schlitze, Einfräsungen oder Bohrungen gestaltet sind, auf, die in der Regel von einem gedachten Brennermittelpunkt aus radial nach außen gerichtet sind. Aus der FR-A-1 303 237 sind schon Gasaustrittskanäle bekannt, deren Mittelachse einen von 0° abweichenden Winkel zu einem der jeweiligen Austrittsöffnung zugeordneten Radius aufweisen. Derartige Gasaustrittskanäle sind auch in anderen Literaturstellen beschrieben, so in der FR-A-1 360 192, der FR-A-1 479 360, der FR-A-1 527 971, der BE-A-645 327, der NL-A-36 302 oder der US-A-1 598 996.Gas burners for cookers are known in various designs. The known burners have flame outlet openings, which are designed as slots, millings or bores, which are generally directed radially outward from an imaginary center of the burner. From FR-A-1 303 237 gas outlet channels are already known, the central axis of which have an angle deviating from 0 ° to a radius assigned to the respective outlet opening. Such gas outlet channels are also described in other references, for example in FR-A-1 360 192, FR-A-1 479 360, FR-A-1 527 971, BE-A-645 327, NL-A -36,302 or US-A-1,598,996.
Die eingangs schon genannte FR-A-1 303 237 ist mit einem dachförmigen oberen Außenrand versehen, um das Eindringen von überkochender Speise oder überkochenden Flüssigkeiten in die Gasaustrittsöffnungen dachartig zu verhindern. Dabei ist aus der BE-A-902 029 eine kompakte Gasbrennergestaltung bekannt, bei der, anders als bei anderen Lösungen, die Gasaustrittsöffnungen nicht im Brennerdeckel, sondern in einem Brennerring angeordnet sind, was die Gestaltungsmöglichkeit derartiger Brenner vereinfachen kann.The FR-A-1 303 237 already mentioned at the beginning is provided with a roof-shaped upper outer edge to prevent penetration to prevent overcooking food or boiling liquids into the gas outlet openings. A compact gas burner design is known from BE-A-902 029, in which, unlike in other solutions, the gas outlet openings are not arranged in the burner cap but in a burner ring, which can simplify the design options for such burners.
Im Zuge des Versuches, die Wirkungsgrade derartiger Brenner zu verbessern und insbesondere auch deren Umweltfreundlichkeit, d.h. deren Schadstoffemissionen zu verringern, hat man von herkömmlichen Brennertypen abweichende Brennergestaltungen entwickelt, solche Brennergestaltungen zeigt beispielweise die DE-A-37 09 445.In the course of trying to improve the efficiency of such burners and in particular also their environmental friendliness, i.e. To reduce their pollutant emissions, burner designs deviating from conventional burner types have been developed, such burner designs are shown, for example, in DE-A-37 09 445.
Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der insbesondere bei atmosphärischen Brennern der NOx-Gehalt im Abgas sowie der Gehalt an CO erheblich vermindert wird, und zwar über einen großen Regelbereich zwischen Klein- und Großstellung des Brenners.The object of the invention is to provide a solution with which, in particular in the case of atmospheric burners, the NO x content in the exhaust gas and the CO content are considerably reduced, specifically over a large control range between the small and large positions of the burner.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Brennerdeckel im Bereich der Gasaustrittsöffnungen unter Bildung einer die Gasaustrittsöffnung verkleinernden Umströmungskante die freie Kontur des Brennerringes überragt und daß der Brennerring im unteren Bereich der Gasaustrittsöffnungen deren äußere Randkante überragend ausgebildet ist.This object is achieved according to the invention in that the burner cover projects beyond the free contour of the burner ring in the area of the gas outlet openings to form a flow edge reducing the gas outlet opening that the burner ring in the lower region of the gas outlet openings has an outer edge which is of outstanding design.
Mit der Erfindung werden im wesentlichen drei Maßnahmen kombiniert, die zur Lösung der gestellten Aufgabe beitragen, nämlich es wird eine Wirbelströmung erzeugt, die Gase werden nach Austritt aus den Kanälen über ein gewisses Maß geleitet und die Austrittsquerschnitte der Strömungskanäle werden in Richtung auf den Austritt verringert, was zur Erhöhung der Austrittsgeschwindigkeit führt. Damit lassen sich die gewünschten Abgaswerte erreichen. Die Verbrennung wird darüber hinaus dadurch optimiert, daß die Flammen erst außerhalb des Brennerkopfes beginnen, was den zusätzlichen Effekt hat, daß der Brennerkopf kälter bleibt, d.h. es kommt zu einer gewünschten Flammenkühlung allein durch die Geometrie der Gaskanäle.Essentially three measures are combined with the invention, which contribute to the solution of the task, namely a vortex flow is generated, the gases are guided to a certain extent after exiting the channels and the outlet cross sections of the flow channels are reduced in the direction of the outlet , which leads to an increase in the exit speed. The desired exhaust gas values can thus be achieved. The combustion is also optimized by the fact that the flames only start outside the burner head, which has the additional effect that the burner head remains colder, i.e. The desired flame cooling is achieved solely by the geometry of the gas channels.
Ein zusätzlicher Vorteil besteht darin, daß die Flammen bei einem aufgesetzten Topf nicht den kürzesten Weg von der Flammenaustrittsöffnung zum Topfrand hin sich suchen können, sondern sie sind gezwungen, länger unter der Topfbodenfläche zu verweilen, es ergibt sich eine Art Schraubenströmung unterhalb des Topfbodens. Dies hat zur Folge, daß die Flammenenergie deutlich besser ausgenutzt werden kann, d.h. um gleiche Kochleistungen zu erzielen, kann der Brenner entweder insgesamt kürzer in Betrieb sein oder aber bei verminderter Einstellung betrieben werden, woraus sich zwangsläufig eine insgesamt geringere Schadstoffbelastung der Umwelt ergibt.An additional advantage is that the flames cannot find the shortest path from the flame outlet opening to the rim of the pot when the pot is in place, but are forced to linger longer under the bottom of the pot, resulting in a kind of screw flow below the bottom of the pot. The result of this is that the flame energy can be used much better, ie in order to achieve the same cooking performance, the burner can either be in operation for a shorter period of time or else with a reduced one Attitude are operated, which inevitably results in a lower overall pollution of the environment.
Weitere zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. Die Schlitze können als Bohrungen gestaltet sein, sie können einen geraden oder gekrümmten Verlauf sowohl in ihrer axialen Richtung als auch in ihrer Querschnittsform aufweisen, es können V-förmige Querschnitte vorgesehen sein als auch parallel nebeneinander angeordnete Kanäle jeweils unterschiedlicher Größe, was zu einer optimalen Regelung zwischen Teillast und Vollast führt. Wie an sich bekannt, können auch Zusatzaustrittsöffnungen zur Bildung von Hilfsflammen vorgesehen sein.Further expedient refinements of the invention result from the subclaims. The slots can be designed as bores, they can have a straight or curved course both in their axial direction and in their cross-sectional shape, V-shaped cross-sections can be provided as well as channels of different sizes arranged in parallel next to each other, which results in optimal control between partial load and full load. As is known per se, additional outlet openings can also be provided to form auxiliary flames.
Um innerhalb des Brenners die Strömungsverhältnisse den jeweiligen Einsätzen besser anpassen zu können, kann es zweckmäßig sein, den Brennerdeckel mit einem Strömungsleitkegel zu versehen und/oder mit Verwirbelungs-/Kühlrippen.In order to be able to better adapt the flow conditions to the respective applications within the burner, it may be expedient to provide the burner cover with a flow guide cone and / or with swirling / cooling fins.
Es hat sich gezeigt, daß auch spezielle Anpassungen zwischen Außenkontur des Brennerdeckels und der Außenkontur des Brennerringes relativ zu den Austrittskanten der Gasaustritte ein unterschiedliches Brennverhalten ergeben, so daß die Erfindung hier spezielle Gestaltungen je nach Einsatzzweck vorsieht, wie in Unteransprüchen angegeben.It has been shown that special adjustments between the outer contour of the burner cover and the outer contour of the burner ring result in a different combustion behavior relative to the outlet edges of the gas outlets, so that the invention provides special designs depending on the intended use, as specified in the subclaims.
Auch können die Strömungskanäle im Inneren der Brenner, ob mit oder ohne Strömungskegel, erfindungsgemäß unterschiedlich gestaltet sein.The flow channels inside the burner, whether with or without a flow cone, can also be designed differently according to the invention.
Schießlich kann es zweckmäßig sein, im Steckaufsatz für zusätzliche Austrittsöffnungen zu sorgen, aus denen Sekundärluft aus dem Muldenraum unterhalb des Brenners zur Flammenkühlung ansaugbar ist, wie dies in weiterer Ausgestaltung der Erfindung ebenfalls vorgesehen ist. Diese Maßnahme der Flammenkühlung dient auch der optimalen Brennstoffausnutzung einerseits bei Reduzierung der Schadstoffemissionen andererseits.Finally, it can be expedient to provide additional outlet openings in the plug-in attachment, from which secondary air can be drawn in from the trough space below the burner for flame cooling, as is also provided in a further embodiment of the invention. This measure of flame cooling also serves to optimize the use of fuel on the one hand while reducing pollutant emissions on the other.

Der in Fig. 1, 1a zum Teil geschnitten wiedergegebene, allgemein mit 1 bezeichnete Gasbrenner hat den folgenden Aufbau:The gas burner shown partially in section in FIGS. 1, 1a, generally designated 1, has the following structure:
Von unten durchsetzt ein Brennerstativ 2 mit einem Injektor 20, eine andeutungsweise wiedergegebene Gasmulde 3. Den über die Gasmulde 3 hinausragenden Bereich des Brennerstativs umgibt ein Steckaufsatz 4, auf den ein Brennerring 5 gelagert ist, der in Fig. 1 teilweise in Aufsicht wiedergegeben ist. Abgeschlossen wird nach oben der Brenner von einem Brennerdeckel 6, der im in Fig. 1 dargestellten Beispiel zentrisch mit einem nach innen weisenden Strömungskegel 7 ausgerüstet ist.From below, a
Erkennbar ist der Brennerring 5 mit einer Vielzahl von Gasaustrittskanälen 8 ausgerüstet, deren in Fig. la mit einem Pfeil 9 angegebene Mittelachse in einem von 0° abweichenden Winkel zu dem entsprechenden, mit 10 bezeichneten Radius steht, der Winkel ist in Fig. 1a mit α bezeichnet. Das freie Austrittsende der Gasaustrittskanäle 8 trägt das Bezugszeichen 8a.The
In Fig. 6 ist, ähnlich wie in Fig. 1a, in Aufsicht der Brennerring 5 dargestellt mit angedeuteten Flammen 11, die erkennbar nicht radial nach außen gerichtet sind, sondern einen Winkel zur Radialströmung aufweisen, derart, daß sich eine Wirbelbildung ergibt. Die in Fig. 6 bzw. 1a dargestellten Kanäle 8 sind dort in Aufsicht gerade ausgebildet, in Fig. 7 ist die Möglichkeit dargestellt, diese Kanäle bogenförmig zu gestalten. Die dort wiedergegebenen Kanäle tragen das Bezugszeichen 8', die gebildeten Flammen das Bezugszeichen 11'.In Fig. 6, similar to Fig. 1a, the
Können die Kanäle 8 bzw. 8' in Aufsicht gerade oder gekrümmt ausgebildet sein, so können sie die unterschiedlichsten Querschnittsformen aufweisen, eine Auswahl dieser Querschnittsformen ist in Fig. 9 angedeutet. Neben querschnittlich U-, V- oder I-förmigen Kanälen können auch Kanäle kreisförmigen Querschnitts vorgesehen sein, dies ist in Fig. 9 mit 8'' angegeben, oder nebeneinanderliegende mit unterschiedlicher Querschnittsgröße, dies ist in Fig. 9 mit 8'' angegeben.If the
Wie an sich bekannt, können unterhalb der Gasaustrittskanäle weitere Gasaustrittsschlitze oder Bohrungen, in Fig. 2 mit 11 bezeichnet, vorgesehen sein, um z.B. bei Vollast Hilfsflammen zu bilden, was in Fig. 2 mit einem Pfeil 12 angedeutet ist, während der Gasströmungsverlauf durch die Gasaustrittskanäle 8 mit 13 bezeichnet ist.As is known per se, further gas outlet slots or bores, designated 11 in FIG. 2, can be provided below the gas outlet channels, in order to e.g. to form auxiliary flames at full load, which is indicated in FIG. 2 by an
In Fig. 3 ist dabei zusätzlich wiedergegeben, daß Zusatzöffnungen 14 vorgesehen sein können, um von unterhalb der Mulde 3 Sekundärluft anzusaugen, die der Flammenkühlung dient, der Strömungsweg dieser Sekundärluft ist in Fig. 3 mit 15 bezeichnet.In Fig. 3 it is also shown that
Soweit wie möglich, tragen in den unterschiedlichen Zeichnungen funktionell gleiche Bauteile auch das gleiche Bezugszeichen. So ist der Brennerdeckel beispielsweise durchgängig mit 6 bezeichnet, selbst wenn er eine zu anderen Darstellungen abweichende Querschnittsform oder Randgestaltung aufweist.As far as possible, functionally identical components in the different drawings have the same reference numerals. For example, the burner cap is designated 6 throughout, even if it has a cross-sectional shape or edge design that differs from other representations.
Der Strömungskegel 7, auch dieses Bezugszeichen ist in allen Figuren durchgängig benutzt, kann querschnittsmäßig einen gekrümmten oder auch einen geraden Verlauf aufweisen, wie dies in Fig. 8 bzw. 8b dargestellt ist. Hier ist der Einfachheit halber der gekrümmte Strömungskegel mit 7 bezeichnet (Fig. 8a) und mit 7' im geraden Verlauf im Falle der Fig. 8b. Zusätzlich können neben dem Strömungskegel z.B. im Deckel 6 auch Kühlrippen 16 vorgesehen sein, die etwa zur Vorverwirbelung einen spiralförmigen Verlauf aufweisen können oder aber auch den Strömungskegel konzentrisch umgeben können, unterschiedliche Querschnittsformen sind in Fig. 5a und 5b wiedergegeben.The
In Fig. 10 sind Strömungsverläufe bei unterschiedlichen Lastbereichen mit Pfeilen angegeben.In FIG. 10, flow profiles for different load ranges are indicated by arrows.

In Fig. 11 überragen die freien Kanten 6a und 5a die Gasaustrittsöffnungen 8a. In Fig. 12 ist eine der Fig. 11 ähnliche Gestaltung wiedergegeben, allerdings sind hier die Übergangsbereiche zu den freien Außenkanten 6a bzw. 5a divergierend wiedergegeben, in Fig. 13 ergibt sich ein konvergierender Verlauf.In Fig. 11, the free edges 6a and 5a protrude beyond
Alle Gestaltungen der Gasaustrittskanäle 8 und der Geometrien an den Gasaustrittsöffnungen 8a führen zu unterschiedlichen Brennverhalten und damit unterschiedlichen Schadstoffemissionen, wobei hier sowohl als Parameter das eingesetzte Gas, der Gasdruck, die Umgebungstemperatur u. dgl. eingeht. Je nach Gassorte bieten sich entsprechend unterschiedlich gestaltete Geometrien an.All designs of the
In den Fig. 14 bis 17 sind Variationen der inneren Gasströmungswege dargestellt. So zeigt Fig. 14 einen sich bauchig erweiternden, mit 17 bezeichneten Anströmraum für das Gas vor Eintritt in die Gasaustrittskanäle 8. Fig. 15 zeigt einen im wesentlichen parallel geführten Gasströmungsweg 17'. Fig. 16 zeigt einen sich von innen nach außen erweiternden Bereich 17'', der durch einen Gasleit- bzw. -umlenkkörper 18 im Brennerinneren bewirkt wird. Schließlich ist in Fig. 17 ein weiterer Schikaneeinsatz 18' dargestellt, der insbesondere die Sekundärflammenbildung optimiert.14 through 17 show variations of the internal gas flow paths. Thus, FIG. 14 shows a bellows-widening inflow space designated 17 for the gas before entering the
In Fig. 18 ist noch ein weiteres Ausführungsbeispiel der Erfindung dargestellt, wobei die ansonsten relativ zur Fig. 1 gleichen Teile das gleiche Bezugszeichen tragen ergänzt durch ein "c". Hier ist der Injektor 20c mittels eines Spannringes 21 am Stativ 2c festgelegt, wobei mit dem Spannring 21 gleichzeitig der Steckaufsatz 4c am Blech der Kochmulde 3c festgelegt werden kann.A further exemplary embodiment of the invention is shown in FIG. 18, wherein the parts that are otherwise the same as in FIG. 1 have the same reference numerals, supplemented by a "c".
