Description

Die Erfindung betrifft einen Brenner zur Erwärmung von Luft nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a burner for heating air according to the preamble of patent claim 1.

Bei bekannten Brennern dieser Art bestehen die mit Gasauslassöffnungen versehenen Rohre aus geraden Rohrstücken, an die die gegebenenfalls gewellten, sich keilförmig erweiternden Mischplatten befestigt sind, wobei die endseitigen, V-förmigen Spalte durch Endplatten verschlossen sind, von denen eine mit der Zündelektrode versehen ist. Ausserhalb der Mischplatten sind in dem Luftkanal von Hand einstellbare Luftleitbleche vorgesehen, mit denen sich die Menge der durch die Mischplatten hindurchtretenden Frischluft steuern lässt.In known burners of this type, the tubes provided with gas outlet openings consist of straight tube pieces to which the possibly corrugated, wedge-shaped widening mixing plates are fastened, the end-side, V-shaped gaps being closed by end plates, one of which is provided with the ignition electrode. Outside the mixing plates, manually adjustable air baffles are provided in the air duct, with which the amount of fresh air passing through the mixing plates can be controlled.

Die bekannten Brenner arbeiten bei ausreichend grosser paralleler Luftströmung bei höherer Leistung, also bei höheren Temperaturen gut. Wird jedoch zur Verringerung der Leistung oder Temperatur weniger Gas eingespeist, verbrennt das Gas nur auf der Gaszuführungsseite des Rohrs, an der auch die Zündelektrode angeordnet ist. Es ergibt sich daher der Nachteil, dass bei unvollständiger Verbrennung des Gases ein ungleichmässiges Temperaturprofil entsteht. Die einseitige Verbrennung des Gases bildet sich dann noch stärker aus, wenn die mit den Gasauslassöffnungen und den Mischplatten versehenen Rohre zu L-, T- oder H-förmigen Brennern zusammengesetzt sind, weil die Flammen nur erschwert über die durch den Brenner gebildeten Ecken überspringen. Es ergeben sich also ungleichmässige, zerrissene Flammenbilder, die eine optimale Verbrennung verhindem.The known burners work well with a sufficiently large parallel air flow at higher output, that is to say at higher temperatures. However, if less gas is fed in to reduce the power or temperature, the gas burns only on the gas supply side of the tube, on which the ignition electrode is also arranged. The disadvantage therefore arises that if the gas is incompletely burned, an uneven temperature profile arises. The one-sided combustion of the gas develops even more when the pipes provided with the gas outlet openings and the mixing plates are assembled into L, T or H-shaped burners because the flames are difficult to jump over the corners formed by the burner. So there are uneven, torn flame patterns that prevent optimal combustion.

Aufgabe der Erfindung ist es daher, einen Brenner der eingangs angegebenen Art zu schaffen, der auch bei verminderter Gaszuführung eine gleichmässige Verbrennung des Gases über seine Länge gewährleistet.The object of the invention is therefore to provide a burner of the type specified at the outset, which ensures even combustion of the gas over its length even when the gas supply is reduced.

Erfindungsgemäss wird diese Aufgabe durch die in dem kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst. Aufgrund seines ringförmigen Aufbaus lässt sich der erfindungsgemässe Brenner derart in dem von der Luft durchströmten Kanal anordnen, dass sich gleichmässige Strömungsprofile ergeben, die die Verbrennung begünstigen. Durch das in axialer Richtung verschiebliche konusförmige Luftleitblech lässt sich in einfacher Weise die durch die Mischplatten hindurchströmende Luftmenge steuern. Die Menge der durch die äussere ringförmige Mischplatte strömenden Luft hängt von der Grösse des ringförmigen Spalts zwischen dem Rand dieser ringförmigen Mischplatte und dem Luftleitblech ab, die sich durch Verschiebung des Luftleitbleches in der gewünschten Weise verändern lässt.According to the invention, this object is achieved by the features specified in the characterizing part of patent claim 1. Because of its ring-shaped structure, the burner according to the invention can be arranged in the duct through which the air flows so that uniform flow profiles result which promote combustion. The amount of air flowing through the mixing plates can be controlled in a simple manner by means of the conical air baffle that can be displaced in the axial direction. The amount of air flowing through the outer annular mixing plate depends on the size of the annular gap between the edge of this annular mixing plate and the air baffle, which can be changed in the desired manner by moving the air baffle.

Aus der Veröffentlichung US-A Nr. 3193265 ist ein Brenner zur Erwärmung von Luft bekannt, der mit einem an eine Gaszuführung angeschlossenen, kreisringförmigen Rohr versehen ist, das auf einem Kreis angeordnete Gasauslassöffnungen aufweist. Das kreisringförmige Rohr ist mit zueinander konzentrischen zylinderringförmigen Stegen verbunden, die zwischen sich die Gasauslassöffnungen einfassen. Diese Stege sind jedoch nicht mit Durchtrittsöffnungen für die Luft versehen und weiterhin sind keine Luftleitblechevorgesehen, die mit den Stegen in der Weise zusammenwirken können, dass eine zwischen die Stege strömende Luftmenge gesteuert werden könnte.From publication US-A No. 3193265 a burner for heating air is known, which is provided with an annular pipe connected to a gas supply, which has gas outlet openings arranged on a circle. The annular tube is connected to mutually concentric, cylindrical ring-shaped webs which surround the gas outlet openings between them. However, these webs are not provided with through-openings for the air and, furthermore, no air baffles are provided which can interact with the webs in such a way that an amount of air flowing between the webs could be controlled.

Nach einer besonders vorteilhaften Ausführungsform ist vorgesehen, dass das Rohr mindestens zwei konzentrische Kanäle aufweist, die im Bereich der Gaszuführung durch Zwischenwände voneinander getrennt und auf der der Gaszuführung gegenüberliegenden Seite der ersten Trennwand mit einer die Kanäle verbindenden Gasüberströmleitung versehen sind. Durch diese Hintereinanderschaltung von konzentrischen, kreisringförmigen Kanälen wird erreicht, dass der nachfolgende Kanal erst dann von Gas durchströmt wird, wenn der erste Kanal voll mit Gas gefüllt ist. Da aus den Gasauslassöffnungen des ersten Kanals auch im Teilleistungsbereich eine ausreichende Menge von Gas ausströmt, ergibt sich eine gleichmässige kreisringförmige Flamme, die eine vollständige Verbrennung und ein gleichmässiges Temperaturprofil sicherstellt. Bei höherer Leistung strömt das nicht bereits durch die Gasauslassöffnungen des ersten Ringkanals ausgetretene Gas in den oder die nachgeschalteten Ringkanäle, so dass sich ohne wesentliche Änderung des Temperaturprofils höhere Lufttemperaturen erreichen lassen. Das aus den dem ersten Ringkanal folgenden Ringkanälen austretende Gas vergrössert die gesamte, zur Verbrennung kommende Gasmenge, wobei aufgrund der bereits durch den ersten Kanal erzeugten ringförmigen Flamme eine vollständige Verbrennung des Gases sichergestellt ist. Statt eines kreisringförmigen Rohres, das durch eine oder mehrere umlaufende Trennwände in konzentrische Ringkanäle unterteilt ist, können auch zwei oder mehrere konzentrische Rohre vorgesehen werden.According to a particularly advantageous embodiment, it is provided that the tube has at least two concentric channels which are separated from one another by intermediate walls in the region of the gas supply and are provided with a gas overflow line connecting the channels on the side of the first partition opposite the gas supply. This series connection of concentric, circular channels ensures that gas flows through the subsequent channel only when the first channel is completely filled with gas. Since a sufficient amount of gas flows out of the gas outlet openings of the first channel even in the partial power range, a uniform circular flame results, which ensures complete combustion and a uniform temperature profile. At higher power, the gas that has not already escaped through the gas outlet openings of the first ring channel flows into the ring channel or the downstream ring channels, so that higher air temperatures can be achieved without a significant change in the temperature profile. The gas emerging from the ring channels following the first ring channel increases the total amount of gas coming to the combustion, a complete combustion of the gas being ensured due to the annular flame already generated by the first channel. Instead of an annular tube which is divided into concentric ring channels by one or more circumferential partition walls, two or more concentric tubes can also be provided.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.Further advantageous embodiments of the invention are described in the dependent claims.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigt:

  • Fig.1 einen Axialschnitt durch ein einen Luftkanal begrenzendes Rohr im Bereich eines ringförmigen Brenners,
  • Fig. 2 eine Draufsicht auf eine Hälfte des ringförmigen Brenners,
  • Fig. 3 eine Draufsicht auf einen Ausschnitt von Mischplatten, und
  • Fig. 4 eine Draufsicht auf eine Hälfte eines nur mit einem Ringkanal versehenen Brenners.
An embodiment of the invention is explained below with reference to the drawing. In this shows:
  • 1 shows an axial section through a tube delimiting an air duct in the region of an annular burner,
  • 2 is a plan view of one half of the annular burner,
  • Fig. 3 is a plan view of a section of mixing plates, and
  • Fig. 4 is a plan view of one half of a burner provided only with an annular channel.

In einem von zu erwärmender Luft durchströmten rohrförmigen Luftkanal 1 ist über nicht dargestellte Haltestücke ein ringförmiger Brenner 2 befestigt, dessen Achse mit der Luftkanalachse übereinstimmt. Der Brenner 2 besteht aus einem ringförmigen Rohr, das in seiner Mittelebene in zwei schalenförmige Körper 3, 4 unterteilt ist. Die schalenförmigen Körper 3, 4 sind mit ringförmig umlaufenden mittleren Trennwänden bzw. Stegen 7, 8 versehen, die das Brennerrohr in zueinander konzentrische Kanäle 9, 10 unterteilen. Beidseits des Steges 7 ist die Rohrschale 4 mit Gasauslassöffnungen 11, 12 versehen, die auf zueinander konzentrischen Kreisen angeordnet sind. Die durch die Gasauslassöffnungen 11, 12 gebildeten Düsenöffnungen münden auf der Stirnseite eines mit der Rohrschale 4 verbundenen ringförmigen Steges, an dessen zylindrischen Innen- und Aussenseiten trichterförmige Mischplatten 13, 14 befestigtsind. Die Mischplatten 13, 14sind in der aus Fig. 3 ersichtlichen Weise mit Durchtrittsöffnungen 15 unterschiedlicher Grösse für die Luftversehen.An annular burner 2, the axis of which coincides with the axis of the air duct, is fastened in a tubular air duct 1 through which air to be heated flows, via holding pieces (not shown). The burner 2 consists of an annular tube which is divided into two bowl-shaped bodies 3, 4 in its central plane. The bowl-shaped bodies 3, 4 are provided with annular partition walls or webs 7, 8 provided that divide the burner tube into channels 9, 10 which are concentric with one another. The tube shell 4 is provided on both sides of the web 7 with gas outlet openings 11, 12 which are arranged on circles which are concentric with one another. The nozzle openings formed by the gas outlet openings 11, 12 open on the end face of an annular web connected to the tubular shell 4, on the cylindrical inner and outer sides of which funnel-shaped mixing plates 13, 14 are fastened. The mixing plates 13, 14 are provided with through openings 15 of different sizes for the air in the manner shown in FIG. 3.

Wie aus Fig. 2 ersichtlich ist, sind die Kanäle 9, 10 links neben einem Anschlussstutzen 16 für das Gas mit Querwänden 17, 18 versehen. Links neben den Querwänden 17,18 sind die Kanäle 9,10 durch eine Durchtrittsöffnung 19 miteinander verbunden. Das durch den Rohrstutzen 16 zugeführte Gas strömt also zunächst in Richtung der eingezeichneten Pfeile durch den äusseren Kanal 9 und tritt erst dann durch die Durchtrittsöffnung 19 in den inneren Kanal ein, wenn es nicht bei seiner Strömung durch den äusseren Kanal 9 vollständig durch die mit diesem verbundenen Gasauslassöffnungen 12 ausgetreten ist.As can be seen from Fig. 2, the channels 9, 10 are provided on the left next to a connecting piece 16 for the gas with transverse walls 17, 18. The channels 9, 10 are connected to one another to the left of the transverse walls 17, 18 by a passage opening 19. The gas supplied through the pipe socket 16 thus initially flows in the direction of the arrows through the outer channel 9 and only enters the inner channel through the passage opening 19 if it does not completely flow through the outer channel 9 with the flow through the outer channel 9 connected gas outlet openings 12 has emerged.

Zur Steuerung der durch die äussere Mischplatte 13 strömenden Luft ist ein sich in Strömungsrichtung konusförmig verengendes Luftleitblech 20 vorgesehen, das auf der Innenwandung des Luftkanals 1 in axialer Richtung verschieblich geführt ist. Das Luftleitblech 20 ist mit ausgezogenen Linien in einer vorgeschobenen Stellung dargestellt, in der zwischen dieser und dem äusseren Rand der äusseren Mischplatte 13 ein relativ grosser Ringspalt vorhanden ist, so dass die Hauptmenge der Luft aussen an der äusseren Mischplatte 13 vorbeiströmen kann, ohne durch deren Löcher hindurchzutreten. In Fig. 1 ist mit gestrichelten Linien das Luftleitblech 20 in einer zurückgeschobenen Stellung dargestellt, in der zwischen dieser und dem äusseren Rand der Mischplatte 13 nur ein relativ schmaler Ringspalt vorhanden ist, so dass ein grösserer Teil der zugeführten Luftmenge durch die Mischplatten strömt.In order to control the air flowing through the outer mixing plate 13, an air baffle plate 20 that narrows conically in the direction of flow is provided, which is displaceably guided in the axial direction on the inner wall of the air duct 1. The air baffle 20 is shown in solid lines in an advanced position in which there is a relatively large annular gap between it and the outer edge of the outer mixing plate 13, so that the majority of the air can flow past the outer mixing plate 13 without passing through it To pass holes. In Fig. 1, the air baffle 20 is shown in dashed lines in a retracted position, in which there is only a relatively narrow annular gap between it and the outer edge of the mixing plate 13, so that a larger part of the supplied air flows through the mixing plates.

Vor den auf konzentrischen Ringen angeordneten Gasauslassöffnungen 11,12 ist in der äusseren Mischplatte 13 ein Zündgasrohr 22 angeordnet. Zur lonisationsüberwachung ist in der inneren Mischplatte 14 ein Fühler 23 vorgesehen.An ignition gas tube 22 is arranged in the outer mixing plate 13 in front of the gas outlet openings 11, 12 arranged on concentric rings. A sensor 23 is provided in the inner mixing plate 14 for ionization monitoring.

In dem Ausführungsbeispiel nach Fig. 4 besteht das Brennerrohr aus zwei schalenförmigen Hälften, die nur einen Ringkanal begrenzen, in den der Rohrstutzen mündet. Die Gasauslassöffnungen befinden sich auf der anderen, nicht dargestellten schalenförmigen Hälfte.In the exemplary embodiment according to FIG. 4, the burner tube consists of two shell-shaped halves which only delimit an annular channel into which the pipe socket opens. The gas outlet openings are on the other, shell-shaped half, not shown.
