Description

Die Erfindung betrifft einen atmosphärischen Gasbrenner nach dem Oberbegriff des Anspruchs 1.The invention relates to an atmospheric gas burner the preamble of claim 1.

Nach der DE 197 47 481 C1 ist ein Gasbrenner mit einem Brennerkörper und einem Basisteil (Gas-Luft-Mischstrecke) bekannt, die für Wartungsarbeiten einfach mittels eines Schnellspann-Verschlusses voneinander lösbar ausgebildet sind. Da am Brennerkörper aufgrund der Verbrennung des Gas-Luft-Gemisches hohe Temperaturen herrschen, ist das Basisteil als Gussteil ausgebildet.According to DE 197 47 481 C1 is a gas burner with a burner body and a base part (gas-air mixing section) is known, for maintenance work simply by means of a quick release lock are detachable from each other. Because on the burner body due to the combustion of the gas-air mixture high Temperatures prevail, the base part is designed as a cast part.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Brenner der eingangs genannten Art die Herstellungs- und Materialkosten zu senken.The invention has for its object in a burner the manufacturing and material costs of the type mentioned at the beginning to lower.

Diese Aufgabe ist nach der Erfindung mit einem atmosphärischen Gasbrenner der eingangs genannten Art durch die im Kennzeichen des Anspruchs 1 genannten Merkmale gelöst.This object is according to the invention with an atmospheric Gas burner of the type mentioned by the in the license plate of claim 1 features solved.

Erfindungsgemäß ist also vorgesehen, gaszufuhrseitig an der Brennfläche eine aus Kunststoff bestehende Gas-Luft-Gemischstrecke anzuordnen und die Brennfläche im Direktverbund mit dem mindestens einen Kühlkanal auszubilden, d.h. die Brennfläche und der Kühlkanal sollen unmittelbar, also ohne (wie bisher) jegliche Wärmebrücken, in Wärmekontakt stehen. Auf diese Weise ist es möglich, hinreichend große Wärmemengen von der Brennfläche ans Kühlwasser abzuführen, so dass die Gas-Luft-Mischstrecke aus preiswertem und leicht zu verarbeitenden Kunststoff gebildet sein kann. According to the invention it is therefore provided on the gas supply side on the Burning surface of a gas-air mixture section made of plastic to arrange and the focal surface in direct connection with to form the at least one cooling duct, i.e. the focal surface and the cooling channel should be immediate, i.e. without (as before) any thermal bridges, in thermal contact. To this Way it is possible to get sufficiently large amounts of heat from the To discharge the burning surface to the cooling water, so that the gas-air mixing section from inexpensive and easy to process Plastic can be formed.

Nach der DE 195 45 844 A1 ist zwar schon ein einstückig im Strangpressverfahren hergestellter Brenner mit integrierten Kühlkanälen bekannt. Dieser Konstruktion liegt aber die Aufgabe zugrunde, einem möglichst einfach aufgebauten und leicht zu fertigenden Gasbrenner mit erhöhter Temperaturbeständigkeit der Brennerfläche zu schaffen. Eine separate Fertigung der Gas-Luft-Mischstrecke (noch dazu aus Kunststoff) ist bei dieser Konstruktion nicht nahegelegt, da sonst die angestrebte möglichst einfache Fertigung gerade nicht mehr möglich wäre, zumal bei diesem Brenner die Mischkammer mit einem flachen, sich in die Breite erstreckenden Venturikanal mit rechteckförmigen Einlaßquerschnitt versehen ist, der sich besonders einfach durch Strangpressen herstellen läßt.According to DE 195 45 844 A1, one is already in one piece Extrusion process burner with integrated Cooling channels known. But this construction is the task based on a simple and light structure gas burner to be manufactured with increased temperature resistance to create the burner surface. A separate production of the Gas-air mixing section (also made of plastic) is with this Construction not suggested, otherwise the target manufacturing as simple as possible would no longer be possible, especially with this burner the mixing chamber with a flat, extending venturi channel with a rectangular shape Inlet cross section is provided, which is particularly simple can be produced by extrusion.

Der stofflicher Verbund aus Brennfläche und Kühlkanal bzw. Kanälen läßt sich, wie erwähnt, fertigungstechnisch am besten durch Strangpressen herstellen. Aber auch Gießen führt zum gewünschten stofflichen Verbund.The material combination of focal surface and cooling channel or channels can, as mentioned, best in terms of production technology by extrusion. But casting also leads to desired material combination.

Es ist weiterhin vorteilhaft vorgesehen, dass der Verbundkörper aus Aluminium gebildet ist. Dieses Material hat nicht nur gute Wärmeübertragungseigenschaften, sondern ist auch gut geeignet für die vorbeschriebenen Herstellungsverfahren.It is also advantageously provided that the composite body is made of aluminum. This material has no just good heat transfer properties, but is also good suitable for the manufacturing processes described above.

Bezüglich der Brennfläche ist vorteilhaft vorgesehen, dass die Gasaustrittsöffnungen in Form von in den Verbundkörper wahlweise gefräster oder gesägter Schlitze ausgebildet sind. Auf diese Weise lassen sich in den im Gieß- oder Strangpressverfahren hergestellten Verbundkörper kostengünstig die Gasaustrittsöffnungen einbringen.With regard to the focal surface, it is advantageously provided that the Gas outlet openings in the form of optional in the composite body milled or sawn slots are formed. On this can be done in the casting or extrusion process manufactured composite body inexpensively the gas outlet openings bring in.

Je nach Herstellungsart des Verbundkörpers, also Gießen oder Strangpressen, ergibt sich mindestens ein offener Querschnitt. Um diesen zu verschließen, ist beispielsweise vorgesehen, auf gießtechnischem Herstellungsweg ein zueinander passendes Paar Verbundkörper mit jeweils nur einem offenen Querschnitt herzustellen, der durch Zusammenfügen des Paares verschlossen wird. Fertigungstechnisch günstiger und deshalb vorteilhaft ist alternativ vorgesehen, dass der mindestens eine offene Querschnitt des Verbundkörpers mit einem Deckel verschlossen wird.Depending on the type of manufacture of the composite body, i.e. casting or Extrusion, there is at least an open cross section. In order to close this, it is provided, for example, on a matching pair To produce composite bodies with only one open cross section, which is closed by joining the couple. Manufacturing technology is cheaper and therefore advantageous is alternative provided that the at least one open cross section the composite body is closed with a lid.

Um dem mindestens einen an der Brennfläche angeordneten Kühlkanal auf einfache Weise Kühlwasser zuführen zu können, ist ferner vorteilhaft vorgesehen, dass an dem mindestens einen Deckel Vor- und Rücklaufanschlüsse angeordnet sind.Around the at least one cooling duct arranged on the focal surface to be able to supply cooling water in a simple manner further advantageously provided that at least one Cover flow and return connections are arranged.

Der erfindungsgemäße atmosphärische Gasbrenner und seine vorteilhaften Weiterbildungen werden nachfolgend anhand der zeichnerischen Darstellung eines Ausführungsbeispiels näher erläutert.The atmospheric gas burner according to the invention and its advantageous Further training is based on the graphic representation of an embodiment closer explained.

In Fig. 1 ist ein atmosphärischer Gasbrenner dargestellt, der aus einer mit Gasaustrittsöffnungen 2 versehenen Brennfläche 1 besteht, der gaszufuhrseitig, im Bereich der Gasaustrittsöffnungen 2 insgesamt sechs wasserführende Kühlkanäle 3 zugeordnet sind.In Fig. 1 an atmospheric gas burner is shown, the from a combustion surface 1 provided with gas outlet openings 2 exists, the gas supply side, in the area of the gas outlet openings 2 assigned a total of six water-carrying cooling channels 3 are.

Vor der Brennfläche 1 befindet sich gaszufuhrseitig eine Gas-Luft-Mischstrecke 5 (siehe Fig. 6), die dazu dient, das aus einer Gasleitung kommende Gas mit der benötigten Menge Luft zu vermischen. Diese wannenartig ausgebildete Gas-Luft-Mischstrecke 5 ist in den Fig. 6 bis 8 aus verschiedenen Ansichten dargestellt. Im wesentlichen weist sie drei Bereiche auf, nämlich erstens einen acht Eintrittsöffnungen 13 aufweisenden Gas-Luft-Eintrittsbereich 14, zweitens sich daran anschliessende rohrförmige Gas-Luft-Mischbereiche 15 und drittens eine Kammer 16, die der Brennfläche 1 gaszufuhrseitig vorgeschaltet ist, wobei im Gas-Luft-Eintrittsbereich 14 ein Gasverteiler 17 mit acht Düsen 18 angeordnet ist.In front of the burning surface 1 there is a gas-air mixing section on the gas supply side 5 (see Fig. 6), which is used for the gas coming into a gas line with the required amount of air mix. This trough-shaped gas-air mixing section 5 is in Figs. 6 to 8 from different views shown. It essentially has three areas, namely first, an eight inlet openings 13 Gas-air inlet area 14, secondly adjoining it tubular gas-air mixing areas 15 and third one Chamber 16, which precedes the combustion surface 1 on the gas supply side a gas distributor 17 in the gas-air inlet region 14 is arranged with eight nozzles 18.

Wesentlich für diesen Brenner ist nun, dass die Gas-Luft-Gemischstrecke 5 aus Kunststoff gebildet ist und dass die Brennfläche 1 und die sechs Kühlkanäle 3 einen stofflichen Verbundkörper 4 bilden, der aus gut wärmeleitendem Material besteht.It is essential for this burner that the gas-air mixture section 5 is made of plastic and that Focal surface 1 and the six cooling channels 3 a material Form composite body 4, the good heat-conducting material consists.

Der in Fig. 1 dargestellte Verbundkörper 4 ist als Strangpresskörper ausgebildet. Er besteht aus sich in Strangpressrichtung erstreckenden, im Querschnitt tropfenförmigen und innengerippten Kühlkanälen 3, an deren schmalen Enden die einzelnen Segmente der Brennfläche 1 mit ihren Gasaustrittsöffnungen 2 angeordnet sind. Der Übergangsbereich 11 zwischen der Brennfläche 1 und den Kühlkanälen 3 sorgt für eine effektive Wärmeübertragung. The composite body 4 shown in FIG. 1 is an extruded body educated. It consists of itself in the extrusion direction extending, teardrop-shaped in cross-section and internally ribbed Cooling channels 3, at the narrow ends of the individual Segments of the focal surface 1 with their gas outlet openings 2 are arranged. The transition area 11 between the Focal surface 1 and the cooling channels 3 ensures effective Heat transfer.

Für eine gute Wärmeübertragung ist darüber hinaus vorteilhaft vorgesehen, dass der Verbundkörper 4 aus Aluminium besteht.It is also advantageous for good heat transfer provided that the composite body 4 consists of aluminum.

Die Gasaustrittsöffnungen 2 sind in Form von in den Verbundkörper 4 wahlweise gefräster oder gesägter Schlitze 8 ausgebildet.The gas outlet openings 2 are in the form of in the composite body 4 either milled or sawn slots 8 formed.

Bei dieser Verbundkörperkonstruktion ist es aufgrund ihrer guten Wärmeleiteigenschaften möglich, trotz großer Gasaustrittsöffnungen 2 einen Flammrückschlag auszuschließen. Die Diagramme gemäß Fig. 2 und 3 verdeutlichen die prinzipiellen Zusammenhänge:
Fig. 2 zeigt, dass die häufig störenden Fließgeräusche mit grösser werdendem Austrittsquerschnitt abnehmen. Demgegenüber steigt aber die Gefahr des Flammrückschlags mit zunehmendem Austrittsquerschnitt (siehe Fig. 3). Je niedriger aber die Temperatur an der Brennfläche 1 ist, desto geringer ist die Rückschlaggefahr. Optimal ist also eine Konstellation, bei der große Austrittsquerschnitte zur Vermeidung von Fließgeräuschen vorgesehen sind und die Flamme bzw. das Gas-Luft-Gemisch bei Durchtritt durch die Brennfläche 1 durch eine effektive Kühlung so weit abgekühlt wird, dass ein Flammrückschlag ausgeschlossen werden kann.With this composite structure it is possible due to its good thermal conductivity properties to rule out a flashback despite large gas outlet openings 2. The diagrams according to FIGS. 2 and 3 illustrate the basic relationships:
Fig. 2 shows that the frequently disturbing flow noises decrease with increasing outlet cross-section. In contrast, however, the risk of flashback increases with increasing outlet cross-section (see Fig. 3). However, the lower the temperature at the focal surface 1, the lower the risk of kickback. Optimal is a constellation in which large outlet cross-sections are provided to avoid flow noises and the flame or the gas-air mixture is cooled down as it passes through the combustion surface 1 by effective cooling to such an extent that a flashback can be excluded.

Die sich beim Strangpressen bzw. beim Gießen ergebenden offenen Querschnitte am Verbundkörper 4 werden mit einem Deckel 7 verschlossen. Ein solcher, im Gußverfahren hergestellter Dekkel 7 ist in den Fig. 4 und 5 in Außen- und Innenansicht dargestellt. Er wird mittels eines speziellen Alulötverfahrens am Verbundkörper 1 befestigt. Um das Kühlwasser auf einfache Weise den Kühlkanälen 3 zuzuführen, sind vorteilhaft am Deckel 7 Vor- und Rücklaufanschlüsse 9 angeordnet, an die sich entsprechende, nicht dargestellte Anschlußrohre anschließen.The open ones that result from extrusion or casting Cross sections on the composite body 4 are made with a cover 7 locked. Such a cover, produced in the casting process 7 is shown in FIGS. 4 and 5 in external and internal views. It is made using a special aluminum soldering process Composite body 1 attached. To the cooling water on simple How to supply the cooling channels 3 are advantageous on the lid 7 flow and return connections 9 arranged to which corresponding, Connect connecting pipes, not shown.

Schließlich besteht eine vorteilhafte Weiterbildung darin, dass die Gas-Luft-Mischstrecke 5 per Schnappverschluss 12 am Verbundkörper 4 befestigt ist, wobei ein Dichtungsmittel einen Gasaustritt im Übergangsbereich von der Gas-Luft-Mischstrecke 5 zum Verbundkörper 4 ausschließt.Finally, an advantageous further training consists in that the gas-air mixing section 5 by a snap lock 12 on Composite body 4 is attached, wherein a sealant Gas outlet in the transition area from the gas-air mixing section 5 to the composite body 4 excludes.
