Description
In einen Ofen einsetzbarer Strahlungsbrenner Strahlungsbrenner aus einem porösen Material mit einer vorgeschalteten Mischkammer für das zu verbrennende Brennstoff-Luft-Gemisch sind allgemein bekannt. Das Gemisch dringt durch das poröse Material und wird an dessen Oberfläche unter Erzeugung verhältnismäßig hoher Temperaturen flammenlos verbrannt. Radiant burner that can be used in a furnace Radiant burner off a porous material with an upstream mixing chamber for the to be burned Fuel-air mixtures are well known. The mixture penetrates through the porous Material and is on its surface with the generation of relatively high temperatures burned flameless.
Damit solche Strahlungsbrenner einwandfrei funktionieren, ist ein starker Temperaturabfall zwischen der Brenneroberfläche und der Mischkammer erforderlich, da sonst Rückzündungen nicht auszuschließen sind. in der Regel wird dieses Problem bereits durch das ständig von der Mischkamme r zur Brenneroberfläche 5 strömende Brennstoff-Luft-Gemisch gelöst, welches für eine Kühlung der hinter der Brenneroberfläche liegenden PartIen sorgt.In order for such radiant burners to function properly, a sharp temperature drop is required between the burner surface and the mixing chamber, otherwise backfiring cannot be ruled out. usually this will problem already through the constantly flowing from the mixing chamber r to the burner surface 5 Fuel-air mixture dissolved, which is used for cooling behind the burner surface lying parts.
Während des Betriebes werden zwangsweise die Ofenwände aufgeheizt, sofern nur eine normale Isolierung vorliegt. Da die Ofenwände nicht durch ein strömender Medium entsprechend dem Strahlungsbrenner gekühlt werden, ergibt sich auf der Höhe der Brenneroberfläche etwa die an dieser Stelle vorliegende sehr hohe Temperatur, die sich zur Mischkammer hin nur unwesentlich verringert. Von der Ofenwand her werden die äußeren rückwärtigen Stellen des Strahlungsbrenners unzulässig erwärmt, so daß es zu den gefährlichen.Rückzündungen kommen kann.The furnace walls are forced to heat up during operation, as long as there is only normal insulation. Since the furnace walls are not through a flowing Medium to be cooled according to the radiant burner, results at the height the burner surface is about the very high temperature at this point, which is only insignificantly reduced towards the mixing chamber. From the furnace wall the outer rear points of the radiant burner heated impermissibly, so that dangerous flashbacks can occur.
Für die einwandfreie Funktion des Strahlungsbrenners ist eine Grenzschichtkühlung zwischen dem Brenner und der Ofenwand erforderlich. Zu diesem Zweck wurde bereits vorgeschlagen, zwischen dem Strahlungsbrenner und der Ofenwand einen Ring aus porösen Steinen anzuordnen, der zum Ofenraum hin von Kühlluft durchströmt wird. Die Kühlluft verhindert die Aufheizung des rückwärtigen Bereiches des Strahlungobrenners von der Ofenwand her. Die RUckzündung infolge dieser Aufheizung kann also vermieden werden.Boundary layer cooling is essential for the radiant burner to function properly between the burner and the furnace wall necessary. To this end it has already been proposed to place one between the radiant burner and the furnace wall To arrange a ring made of porous stones, through which the cooling air flows to the furnace chamber will. The cooling air prevents the rear area of the radiation burner from heating up from the furnace wall. The flashback as a result of this heating can therefore be avoided will.
Diese zusätzlich in den Ofenraum einströmende Kühlluft beeinträchtigt jedoch sehr stark die Ofenatmosphäre' was in vielen Fällen unerwünscht ist. Außerdem setzt sie den wermetechnischen Wirkungsgrad herab. Diese Nachteile sollen vermieden werden.This also adversely affects the cooling air flowing into the furnace chamber However, the furnace atmosphere is very strong, which is undesirable in many cases. aside from that it reduces the advertising efficiency. These disadvantages are to be avoided will.
Erfindungsgemäß geschieht dieses durch einen zwischen dem Strahlungsbrenner und der Ofenwand- angeordneten, von einem Kühlmedium durchströmten, dieses Kühlmedium nach außen abführenden Kühlring.According to the invention, this is done by a between the radiant burner and the furnace wall-arranged, through which a cooling medium flows, this cooling medium cooling ring discharging to the outside.
Der Kühlring besteht zweckmäßigerweise aus einem zum Strahlungsbrenner und zum Ofeninnenraum hin abgedichteten porösen Material, wie z.B. Feuerfilz oder aus einzelnen Steinen mit hoher Porosität. Die Abführung des Kühlmediums nach außen geschieht durch Bohrungen oder Röhrchen in der Ofenwand.The cooling ring expediently consists of a radiant burner and porous material sealed from the furnace interior, such as fire felt or made of individual stones with high porosity. The discharge of the cooling medium to the outside happens through holes or tubes in the furnace wall.
Nähere Einzelheiten sind aus der beigefügten Zeichnung, die ein Ausführungsbeispiel der Erfindung darstellt, zu entnehrnen.Further details are from the accompanying drawing, which shows an exemplary embodiment represents the invention to remove.
Die einzige Figur zeigt einen Querschnitt durch einen Strahlungsbrenner im Bereich der Ofenwand.The single figure shows a cross section through a radiant burner in the area of the furnace wall.
Der Ofeninnenraum 1 wird nach außen durch die Ofenwand 2 begrenzt. Aus der Mischkammer 5 tritt das Brennstoff-Luft-Gemisch durch die den Strahlungsbrenner 4 bildenden porösen Steine 5 , an deren Oberfläche 6 es flammenlos verbrennt. Dabei werden die rückwärtigen Partien der Steine von dem strömenden Gemisch gekühlt.The furnace interior 1 is delimited to the outside by the furnace wall 2. From the mixing chamber 5, the fuel-air mixture passes through the radiant burner 4 forming porous stones 5, on the surface 6 of which it burns flameless. Included become the back parts of the stones from the flowing mixture chilled.
Zwischen dem Strahlungsbrenner 4 und der Ofenwand 2 sitzt ein Kühlring, bestehend aus einer Verteilerkammer 7 und einer porösen Materialschicht 8 . Eine vordere Abdeckung 9 verhindert den Eintritt des Kühlmediums in den Ofeninnenraum 1 . Die Abführung des Kühlmediums erfolgt durch Austrittsöffnungen 10 in der Ofenwand 2A cooling ring sits between the radiant burner 4 and the furnace wall 2, consisting of a distribution chamber 7 and a porous material layer 8. One front cover 9 prevents the cooling medium from entering the furnace interior 1 . The cooling medium is discharged through outlet openings 10 in the furnace wall 2
