Die Erfindung bezieht sich auf eine Brennerleiste gemäß dem Oberbegriff des unabhängigen Anspruchs.The invention relates to a burner bar according to the preamble of the independent claim.
In Heizgeräten mit Brennern werden überwiegend Brennerleisten aus Edelstahl verwendet. Der Grund hierfür liegt in der guten Haltbarkeit und Temperaturbeständigkeit des Edelstahls. Um den Schadstoffausstoß weiter zu senken, ist eine Maßnahme die Kühlung der Brennerleiste. Da der Wärmeleitwert von Edelstahl sehr niedrig ist, würde sich bei Einsatz eines Werkstoffes mit hoher Wärmeleitfähigkeit der Schadstoffausstoß weiter senken lassen. Jedoch weisen die meisten klassischen Wärmeleitstoffe, wie Kupfer oder Aluminium, keine gute Formbeständigkeit gegen äußere Belastung und auch keine gute Temperaturbeständigkeit auf. Ebenfalls ist eine Haltbarkeit gegenüber Korrosionsangriff meist nicht gegeben.In heaters with burners, burner strips made of stainless steel are predominantly used. The reason for this is the good durability and temperature resistance of stainless steel. One measure to further reduce pollutant emissions is to cool the burner strip. Since the thermal conductivity of stainless steel is very low, pollutant emissions could be further reduced by using a material with high thermal conductivity. However, most classic thermal conductors, such as copper or aluminum, do not have good dimensional stability against external stress or good temperature resistance. They are also usually not resistant to corrosion.
Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Brennerleiste der eingangs erwähnten Art vorzuschlagen, die sich durch eine gute Wärmeleitfähigkeit bei hoher Temperaturbeständigkeit auszeichnet.The aim of the invention is to avoid these disadvantages and to propose a burner bar of the type mentioned at the beginning, which is characterized by good thermal conductivity and high temperature resistance.

Erfindungsgemäß wird dies bei einer Brennerleiste der eingangs erwähnten Art durch die Merkmale des unabhängigen Anspruches erreicht.According to the invention, this is achieved in a burner bar of the type mentioned at the outset by the features of the independent claim.
Durch die vorgeschlagenen Maßnahmen ist sichergestellt, daß sich die Brennerleiste aufgrund der Edelstahlschichten durch ein hohes Maß an Temperaturbeständigkeit sowie Korrosionsbeständigkeit und Haltbarkeit auszeichnet. Gleichzeitig wird durch die mittlere, aus einem gut wärmeleitenden Material bestehende Schicht eine gute Wärmeleitfähigkeit der Brennerleiste sichergestellt. Dadurch weist die Brennerleiste eine geringe Oberflächentemperatur auf. Infolgedessen ergibt sich auch eine wesentlich höhere Sicherheit gegen ein Rückschlagen der Flammen des Brenners, verglichen mit Brennerleisten aus Edelstahl. Außerdem ergibt sich aufgrund der geringeren Oberflächentemperatur auch eine Verminderung des Schadstoffausstoßes, insbesondere des Ausstoßes an NOx.The proposed measures ensure that the burner bar is characterized by a high degree of temperature resistance, corrosion resistance and durability due to the stainless steel layers. At the same time, the middle layer, which is made of a material with good heat conduction, ensures that the burner bar has good thermal conductivity. This means that the burner bar has a low surface temperature. As a result, there is also significantly greater protection against the burner flames flashing back compared to burner bars made of stainless steel. In addition, the lower surface temperature also reduces pollutant emissions, particularly NO x emissions.
Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:The invention will now be explained in more detail with reference to the drawing.
Fig. 1 eine axonometrische Darstellung einer Brennerleiste und Fig. 2 einen Ausschnitt aus der Brennerleiste nach der Fig. Gleiche Bezugszeichen bedeuten gleiche Einzelheiten.Fig. 1 is an axonometric representation of a burner bar and Fig. 2 is a section of the burner bar according to Fig. The same reference numerals mean the same details.

Die Fig. 1 zeigt eine Brennerleiste 1, die einen im wesentlichen U-förmigen Querschnitt aufweist. Dabei ist im Bereich des U-Steges 2 in einer in dessen Mitte angeordneten Rinne 3 ein Kühlrohr 4 gehalten, wobei das Kühlrohr 4 in gut wärmeleitender Verbindung mit der Brennerleiste 1 steht. Weiter sind im Bereich des Steges 2 Durchbrechungen 5 für ein Gas-Luft-Gemisch angeordnet.Fig. 1 shows a burner bar 1 which has a substantially U-shaped cross section. In the area of the U-shaped web 2, a cooling pipe 4 is held in a groove 3 arranged in the middle of the U-shaped web, whereby the cooling pipe 4 is in a good heat-conducting connection with the burner bar 1. Furthermore, openings 5 for a gas-air mixture are arranged in the area of the web 2.
Die Fig. 2 zeigt einen Querschnitt durch das Material der Brennerleiste 1. Dieses besteht aus einer mittleren Schicht 6 aus einem gut wärmeleitenden Material, wie Kupfer oder Aluminium, und zwei diese abdeckenden Schichten 7 und 8 aus Edelstahl. Dabei sind die Schichten 7 und 8 flächig mit der mittleren Schicht 6 verbunden, z. B. durch Plattieren. Dadurch ist die mittlere Schicht 6 sehr gut gegen Korrosion geschützt, wobei aber die Brennerleiste 1 aufgrund der mittleren Schicht 6 eine sehr gute Wärmeleitfähigkeit aufweist.Fig. 2 shows a cross-section through the material of the burner bar 1. This consists of a middle layer 6 made of a material with good heat conductivity, such as copper or aluminum, and two layers 7 and 8 made of stainless steel covering this. The layers 7 and 8 are connected to the middle layer 6 over a large area, e.g. by plating. This means that the middle layer 6 is very well protected against corrosion, but the burner bar 1 has very good heat conductivity due to the middle layer 6.
