Description

Das Verfahren nach OS 25 51 811. 0 (Riedel) zeigt zwei zu­ sammengebaute Tunnelöfen, welche gegenläufig betrieben werden mit Abgasentnahme aus dem Hochtemperaturbereich.The procedure according to OS 25 51 811. 0 (Riedel) shows two assembled tunnel kilns, which operated in opposite directions are with exhaust gas extraction from the high temperature range.

Nach dem Stand der Technik ergeben sich nach wie vor er­ hebliche Probleme bei der Beseitigung von schwelgashaltigen Abgasen aus Tunnelöfen wie sie z. B. bei der Porenziegel­ herstellung entstehen.According to the state of the art, he still results major problems in the removal of smoldering gas Exhaust gases from tunnel kilns such as B. in the pore brick manufacture arise.

Verschiedene andere bekanntgewordene Verfahren erfordern ebenfalls beträchtlichen Aufwand zur Lösung des Problems z. B. DBP 26 43 406 und OS 26 53 118. Die Aufgabe der Erfin­ dung besteht darin, eine einfachere Methode zur Beseitigung von Schwelgasen anzugeben unter Verwendung zweier Tunnel­ öfen.Various other known methods require also considerable effort to solve the problem e.g. B. DBP 26 43 406 and OS 26 53 118. The task of the Erfin is an easier method of elimination of carbonization gases to be specified using two tunnels ovens.

Gemäß der Erfindung werden in einem Ofen schwelgaserzeugen­ de Produkte gebrannt, im anderen hingegen nicht schwelgas­ erzeugende. Beide Öfen werden vorzugsweise mit gleicher Durchlaufrichtung betrieben, ist jedoch nicht Bedingung. Sie können in beliebiger räumlicher Anordnung zueinander stehen.According to the invention, smoldering gas is generated in an oven de products burned, in the other, however, not smoldering gas generating. Both ovens are preferably the same  Direction of operation is not a requirement. They can be in any spatial arrangement to each other stand.

Die schwelgashaltigen Abgase des einen Ofens werden an des­ sen Eingangsbereich entnommen und in die Kühlzone oder Brenn­ zone des anderen Ofens, welcher mit nicht schwelgaserzeugen­ den Produkten betrieben wird, eingeleitet.The smoldering gases from one furnace are at the removed from the entrance area and into the cooling zone or firing zone of the other furnace which does not produce smoldering gas the products is operated.

Die Abgase des letzteren werden dabei ebenfalls am Ofenein­ gangsbereich oder der Anwärmzone entnommen und in die Atmos­ phäre abgeführt.The exhaust gases from the latter are also on the furnace corridor or the warming zone and into the atmosphere sphere dissipated.

Beim Durchgang der schwelgashaltigen Abgase des ersten Ofens durch die Brennzone des zweiten, werden diese vollständig thermisch gereinigt, da dort üblicherweise Temperaturen von 900 bis ca. 1200°C herrschen.When passing the smoldering gases from the first furnace through the firing zone of the second, these become complete thermally cleaned, as temperatures are usually there prevail from 900 to approx. 1200 ° C.

Der üblicherweise hohe Luftüberschuß bei Tunnelofenabgasen erlaubt die erfindungsgemäße Koppelung von zwei Öfen mit­ einander. Die Lösung bietet sich auch bei bestehenden Anlagen mit zwei Öfen an, denn meist werden heute neben Leichtziegeln auch schwere, sogenannte Schallschutzziegel benötigt.The usually high excess air in tunnel kiln exhaust gases allows the coupling of two furnaces according to the invention each other. The solution is also available for existing systems with two ovens, because today mostly besides light bricks heavy, so-called soundproofing bricks are also required.

1. Verfahren zum Betrieb von mindestens zwei Tunnelöfen von denen im ersten schwelgaserzeugende, im zweiten oder wei­ teren nichtschwelgashaltige Produkte gebrannt werden, da­ durch gekennzeichnet, daß die schwelgashaltigen Abgase des ersten Ofens mindestens zum größten Teil in die Brenn- und/ oder Kühlzone des zweiten Ofens eingeleitet werden und die Abgase des zweiten Ofens im Eingangsbereich des Ofens oder der Anwärmzone entnommen werden, welche schließlich in die Atmosphäre gelangen.1. A method for operating at least two tunnel kilns of which in the first smoldering gas-generating products are burned in the second or white non-smelting gas products, characterized in that the smoldering gas-containing exhaust gases of the first furnace are at least for the most part in the combustion and / or cooling zone of the second Oven are introduced and the exhaust gases from the second furnace in the entrance area of the furnace or the heating zone are removed, which finally reach the atmosphere.
