Description

Die Erfindung bezieht sich auf einen Strahlungsbrenner, bei welchem unter Druck stehender Brennstoff in eine Kammer injiziert und Verbrennungsluft zugemischt wird, während die abgeleiteten Verbrennungsgase die Innenwand eines nach unten divergierenden Reflektors aufheizen und fühlbare Wärme an wenigstens die Verbrennungsluft rekuperativ übertragen.The invention relates to a radiant burner in which pressurized fuel is injected into a chamber and combustion air is mixed in, while the derived combustion gases heat up the inner wall of a downwardly diverging reflector and recuperatively transmit sensible heat to at least the combustion air.

Ein derartiger Strahlungsbrenner ist nach der DE-OS 21 07 514 bekannt. Der kegelstumpfartige ausgebildete Reflektor schließt mit einer von einer Brennerplatte gebildeten Scheitelebene ab. In den Reflektorraum ist ein mittig von der Basisebene ausgehender, sich nach oben öffnender Konus eingesetzt, der die Verbrennungsgase innerhalb des Reflektorraums umleitet und sie durch die mehrschichtige Reflektorwand führt, wobei die Verbrennungsgase im Gegenstrom fühlbare Wärme an die Verbrennungsluft abgeben, welche mittels eines Gebläses gefördert wird.Somit geben die Verbrennungsgase zunächst ihre Wärme an die Wände des Reflektors ab, welche die aufgenommene Energie entsprechend ihrer Temperatur abstrahlen. Danach wird die noch verbleibende, restliche Energie der Verbrennungsgase, wie beschrieben, noch weiterhin genutzt.Such a radiation burner is known from DE-OS 21 07 514. The truncated cone-shaped reflector terminates with an apex plane formed by a burner plate. In the reflector chamber there is a cone, which starts in the middle of the base plane and opens upwards, which redirects the combustion gases within the reflector chamber and guides them through the multi-layer reflector wall, the combustion gases emitting sensible heat in counterflow to the combustion air, which is conveyed by a fan This means that the combustion gases first give off their heat to the walls of the reflector, which radiate the energy absorbed according to their temperature. After that, the remaining energy of the combustion gases, as described, is still used.

Die bekanntgewesene Ausführungsform bedingt einen kompliziert gestalteten Reflektor und infolge der Mehrschichtigkeit gleichfalls eine aufwendige Ausbildung der Reflektorwände. Hinzu kommt, daß eine unmittelbare Wärmeabstrahlung von der Platte des Brenners nicht möglich ist, weil der in den Reflektor eingesetzte Konus diese Strahlung abschirmt. Es kommt daher zu einer Strahlungsreflektion und letztlich zu einer Herabsetzung der Strahlungstemperatur, so daß die Abstrahlung erheblich beeinträchtigt wird.The known embodiment requires a complicated reflector and, due to the multilayer structure, also a complex design of the reflector walls. In addition, direct heat radiation from the burner plate is not possible because the cone inserted into the reflector shields this radiation. There is therefore radiation reflection and ultimately a reduction in the radiation temperature, so that the radiation is considerably impaired.

Der Erfindung liegt von daher die Aufgabe zugrunde, einen Strahlungsbrenner der bezeichneten Art dahingehend zu gestalten, daß einerseits die Vorteile der Abwärmeausnutzung der Verbrennungsgase erhalten bleiben, und daß andererseits die Strahlungsleistung wesentlich verbessert wird. Diese Aufgabenstellung wird durch die Erfindung, wie sie in dpn Patpnt- ansprüchen gekennzeichnet ist, gelöst.The invention is therefore based on the object of designing a radiant burner of the type described in such a way that, on the one hand, the advantages of utilizing the waste heat of the combustion gases are retained, and on the other hand, the radiation output is significantly improved. This problem is solved by the invention as characterized in dpn Pat p nt claims.

Bei dieser Anordnung ist die Abstrahlung vom Brenner in keiner Weise beeinträchtigt. Da es darüber hinaus innerhalb des Reflektorraums zu einem Stau der erzeugten Verbrennungsgase kommt, die von erheblicher Temperatur sind, wird das aus Brennstoff, und zwar in der Regel aus Brenngas, und das aus Luft bestehende verbrennungsfähige Gemisch innerhalb der Nischkammer besonders wirkungsvoll erhitzt. Die Brennkammer ist nämlich mit ihren Wänden unmittelbar dem heißen Verbrennungsgas ausgesetzt, so daß die Wärmeübertragung besonders wirksam ist. Ferner steht die Mischkammer unter der Einwirkung von Wärmestrahlung, die von den Wänden des Reflektors ausgeht. Im Ergebnis wird somit nicht nur ein hoher konvektiver Wärmeübergang erreicht, sondern ein zusätzlicher, beträchtlicher Wärmeübergang durch Strahlung.With this arrangement, the radiation from the burner is in no way impaired. In addition, since there is a build-up of the combustion gases generated within the reflector chamber, which are of considerable temperature, this is made from fuel, usually from fuel gas, and the combustible mixture consisting of air is heated particularly effectively within the mixing chamber. The walls of the combustion chamber are directly exposed to the hot combustion gas, so that the heat transfer is particularly effective. Furthermore, the mixing chamber is exposed to heat radiation which emanates from the walls of the reflector. As a result, not only a high convective heat transfer is achieved, but also an additional, considerable heat transfer through radiation.

Es ist zweckmäßig, wenn ein für die Selbstansaugung der Verbrennungsluft ausgebildetes Anschlußrohr für das Brenngas aus einer der schmalen Stirnseiten des Reflektors herausgeführt ist oder überhaupt außerhalb des Reflektors angeordnet wird. Dieses Anschlußrohr wird dabei, wie an sich bekannt, als Venturi-Rohr gestaltet, bei welchem gasförmiger Brennstoff die zentrale Düse beaufschlagt, so daß die erforderliche Menge an Verbrennungsluft angesaugt wird. Demgegenüber ist die mit dem Brenner einteilig gestaltete Mischkammer vollständig innerhalb des Reflektorraums aufgenommen. Diesem Zweck dienen insbesondere Stege, mit denen die Mischkammer am Scheitel des Reflektors befestigt ist. In vorteilhafter Weiterentwicklung läßt sich die Befestigung auch mittels eines oder mehrerer Verbindungsrohre vornehmen, die zu einem an der Außenwand des Reflektors angebrachten Anschlußrohr führen. Man spart auf diese Weise nicht nur die Stege ein, sondern erzielt eine weitere Vorwärmung des durch die Verbindungsrohre strömenden Gemisches.It is expedient if a connecting tube for the fuel gas, designed for the self-suction of the combustion air, is led out of one of the narrow end faces of the reflector or is arranged at all outside of the reflector. As is known per se, this connecting pipe is designed as a Venturi pipe, in which gaseous fuel acts on the central nozzle, so that the required amount of combustion air is drawn in. In contrast, the mixing chamber designed in one piece with the burner is completely accommodated within the reflector space. This purpose is served in particular by webs with which the mixing chamber is fastened to the apex of the reflector. In an advantageous further development, the attachment can also be carried out by means of one or more connecting tubes which lead to a connecting tube attached to the outer wall of the reflector. This not only saves the webs, but also further preheats the mixture flowing through the connecting pipes.

Der Scheitel des sich nach unten öffnenden Reflektors ist schon aus Gründen der Befestigung der Mischkammer zweckmäßig eine im wesentlichen horizontal liegende Fläche. Letztere kann zweckmäßig auch noch mit einer Keramikplatte mit guten Wärmeisolationseigenschaften verkleidet sein. Eine derartige Keramikplatte hat den Vorteil, bei oberflächlicher Erhitzung mit einem sehr hohen Emissionskoeffizienten Wärme abzustrahlen. Während demnach die Platte des Brenners als primäre Strahlungsfläche wirkt, vermag der insbesondere keramisch verkleidete Scheitel des Reflektors als sekundäre Heizfläche zu wirken. Die letztgenannte Wirkung läßt sich noch steigern, wenn die den Scheitel des Reflektors bildende Fläche bzw. die erwähnte Keramikplatte größer als die Platte des die Mischkammer nach unten begrenzenden Brenners ausgeführt sind. Damit wird zugleich ein größerer Wärmestrahlungsanteil auf die Mischkammer übertragen.The vertex of the reflector opening downwards is expediently an essentially horizontal surface for the reasons of fastening the mixing chamber. The latter can also be expediently clad with a ceramic plate with good thermal insulation properties. Such a ceramic plate has the advantage of emitting heat with a very high emission coefficient when the surface is heated. Accordingly, the burner plate as the primary Radiant surface acts, the ceramically clad apex of the reflector can act as a secondary heating surface. The latter effect can be increased if the surface forming the apex of the reflector or the ceramic plate mentioned is made larger than the plate of the burner delimiting the mixing chamber at the bottom. This means that a larger proportion of heat radiation is transferred to the mixing chamber.

Innerhalb des Reflektorraums stellt sich eine Zirkulationsströmung des Verbrennungsgases ein, die vom Brenner fortwährend abströmen und, nachdem sie den Reflektorraum ausgefüllt haben, aus letzterem entlang einer der Unterkanten austreten. Um den Wärmeaustausch zwischen der Mischkammer und der Zirkulationsströmung zu vergrößern, werden die von der Brennerplatte ausgehenden und sich in Richtung auf den Scheitel erstreckenden Wände der Mischkammer zweckmäßig konkav ausgeführt. Sie passen sich damit der sich bildenden Strömung geometrisch an und vergrößern weiterhin die Wärmeaustauschfläche.A circulating flow of the combustion gas occurs within the reflector space, which flows continuously from the burner and, after having filled the reflector space, emerge from the latter along one of the lower edges. In order to increase the heat exchange between the mixing chamber and the circulation flow, the walls of the mixing chamber which extend from the burner plate and extend in the direction of the apex are expediently made concave. In this way, they adapt geometrically to the flow being formed and further increase the heat exchange surface.

Eine weitere Steigerung der Wärmeabstrahlung läßt sich dadurch erreichen, daß auch die Reflektorwände eine erhebliche Aufheizung erfahren. Zu diesem Zweck sind sie vorteilhaft aus außenseitig wärmeisolierten Blechtafeln gestaltet.A further increase in heat radiation can be achieved in that the reflector walls also experience considerable heating. For this purpose, they are advantageously made of sheet metal panels that are thermally insulated on the outside.

Zur weiteren Veranschaulichung der Erfindung wird auf in Fig. 1 und Fig. 2 schematisch dargestellte Ausführungsbeispiele Bezug genommen.To further illustrate the invention, reference is made to exemplary embodiments shown schematically in FIGS. 1 and 2.

Zu Fig. 1 erkennt man einen Reflektor 6, der aus nach unten divergierenden Reflektorwänden 12 gebildet ist. Die vordere, in der Zeichnungsebene liegende Stirnwand ist nicht dargestellt. Der Grundriß des Reflektors 6 ist mithin rechteckig. Gleichfalls von rechteckigem Grundriß sind die Platte des Brenners 1 und die Mischkammer 2. Letztere ist mit Stegen 8 an die horizontale Fläche 9 des Scheitels des Reflektorraums 3 angeschlossen. Somit kann sich im Reflektorraum 3 eine Strömung der Verbrennungsgase ausbilden, die entsprechend den Stromlinien 13 verläuft. Wenn die Wände der Mischkammer konkav ausgeführt werden, wie in der gestrichelten Darstellunq bezeichnet ist, läßt sich der konvektive Warmeubergang, wie beschrieben, erhohen. Die Verbrennungsgase strömen schließlich entlang der unteren Kanten 4, 5 des Reflektors 6 aus dem Reflektorraum 3 ab, nachdem sie ihre fühlbare Wärme zum erheblichen Teil auf die Mischkammer 2, die Reflektorwände 12 und die im Reflektorscheitel vorgesehene Keramikplatte 10 übertragen haben.1, a reflector 6 can be seen, which is formed from reflector walls 12 diverging downwards. The front end wall lying in the plane of the drawing is not shown. The plan of the reflector 6 is therefore rectangular. Likewise, the plate of the burner 1 and the mixing chamber 2 are of rectangular plan. The latter is connected with webs 8 to the horizontal surface 9 of the apex of the reflector chamber 3. Thus, a flow of the combustion gases can form in the reflector space 3, which flows according to the streamlines 13. If the walls of the mixing chamber are made concave, as indicated in the dashed representation, the convex can Increase active heat transfer as described. The combustion gases finally flow out of the reflector chamber 3 along the lower edges 4, 5 of the reflector 6 after they have largely transferred their sensible heat to the mixing chamber 2, the reflector walls 12 and the ceramic plate 10 provided in the reflector apex.

Das Anschlußrohr für die Versorgung mit Brenngas und Verbrennungsluft kann, wie mit 7' bezeichnet, eine der Schmalseiten des Reflektors durchsetzen. Es kann aber auch an der Außenseite befestigt werden, wie mit 7 dargestellt. In nicht dargestellter Weise wird Brenngas in Richtung des Pfeiles 14 eingeführt, welches sich die Verbrennungsluft ansaugt. Anstelle der Stege 8 können vom Anschlußrohr 7 auch Verbindungsrohre ausgehen, die in die Mischkammer 2 führen und letztere zugleich im Scheitel des Reflektorraums 3 zu befestigen gestatten.The connecting pipe for the supply of fuel gas and combustion air can, as denoted by 7 ', penetrate one of the narrow sides of the reflector. But it can also be attached to the outside, as shown at 7. In a manner not shown, fuel gas is introduced in the direction of arrow 14, which draws in the combustion air. Instead of the webs 8, connecting pipes 7 can also extend from the connecting pipe, which lead into the mixing chamber 2 and at the same time allow the latter to be fastened in the apex of the reflector chamber 3.

Der Reflektor kann nach einer weiteren Ausführungsform der Erfindung auch eine im Querschnitt parabolische Wandung aufweisen. Dieser hat über die von parabolischen Reflektoren her bekannte Reflektionswirkung hinausgehend noch den Vorteil, daß man ihn aus einem einzigen rechteckigen Blechzuschnitt leicht biegen kann.According to a further embodiment of the invention, the reflector can also have a wall which is parabolic in cross section. In addition to the reflection effect known from parabolic reflectors, this has the advantage that it can be easily bent from a single rectangular sheet metal blank.

Nach einer weiteren Ausführungsform der Erfindung ist der Reflektor asymmetrisch ausgebildet. Wenn dies in der Form geschieht, wie es beispielsweise Fig. 2 zeigt, so wird ein besonders breites Strahlungsfeld geschaffen. Zu diesem Zweck ist eine Reflektorwand 15, welche einen Brenner 1 mit einer Mischkammer 2 oder auch noch einen zweiten Brenner 1' mit einer zweiten Mischkammer 2' trägt, geneigt angeordnet. An die obere Kante 16 der Brennerwand 15 schließt sich eine breite Reflektorwand 17 in Richtung nach unten an, während sich an die untere Kante 18 der Reflektorwand 15 eine nur verhältnismäßig schmale Reflektorwand 19 anschließt.According to a further embodiment of the invention, the reflector is asymmetrical. If this is done in the form shown in FIG. 2, for example, a particularly broad radiation field is created. For this purpose, a reflector wall 15, which carries a burner 1 with a mixing chamber 2 or also a second burner 1 'with a second mixing chamber 2', is arranged inclined. At the upper edge 16 of the burner wall 15 there is a broad reflector wall 17 in the downward direction, while at the lower edge 18 of the reflector wall 15 there is an only relatively narrow reflector wall 19.

Wenn im Reflektorraum 3, wie Fig. 2 zeigt, zwei Brenner 1, 1' angeordnet sind, läßt sich nicht nur die Leistung steigern, sondern bei Verschwenkbarkeit der Brenner um ihre Längsachsen 20, 20' auch noch eine Anpassung an besondere Abstrahlungsbedingungen verwirklichen. Die Brenner 1, 1' sind für diesen Zweck bevorzugt parallel zueinander angeordnet. Infolge der Zirkulationsströmung, wie sie in Fig. 1 mit den Stromlinien 13 dargestellt ist, wird für beide Mischkammern 2 und 2' eine befriedigende Vorwärmung des Brenn-Luft-Gemisches durch die heißen Verbrennungsgase sichergestellt.If two burners 1, 1 'are arranged in the reflector space 3, as shown in FIG. 2, not only can the power be increased, but, if the burners can be pivoted about their longitudinal axes 20, 20', they can also be adapted to particular radiation conditions. The Bren ner 1, 1 'are preferably arranged parallel to each other for this purpose. As a result of the circulation flow, as shown in FIG. 1 with the flow lines 13, a satisfactory preheating of the combustion / air mixture by the hot combustion gases is ensured for both mixing chambers 2 and 2 '.
