Abstract

A tunnel furnace includes a carriage which runs very close to the furnace walls, a firing channel and a lower carriage channel located below the main carriage. The main carriage has a skirt section on the end faces. The carriage is connected to other carriages to form trains, and two or more trains run through the furnace and the skirts run against the pedestal members which are located on the floor of the furnace. ADVANTAGE - The furnace is efficient and reliable and is capable of taking two or more carriage trains.

Description

Die Erfindung betrifft einen Tunnelofen entsprechend dem Oberbegriff.The invention relates to a tunnel kiln accordingly the generic term.

Ein Tunnelofen dieser Art ist Gegenstand des Haupt­ patents 36 04 501, wonach der Tunnelofen einsträn­ gig ist, das heißt, nur einen Fahrstrang für einen Ofenwagenzug hat.A tunnel kiln of this type is the subject of the main patents 36 04 501, after which the tunnel kiln dries up gig, that is, only one driveline for one Kiln car train has.

Es ist bekannt, daß mehrere Ofenwagenzüge parallel nebeneinander ohne Zwischenwände einen entsprechend mehrsträngigen Tunnelofen durchfahren. Die Ofenwagen sind an ihren Längsseiten mit Sandschürzen ausgerüstet, die in mit Sand gefüllte Rinnen im Ofenfundament eintau­ chen, um eine Dichtung zum Unterwagenkanal zu schaffen. Dabei ist ein größerer Abstand zwischen den Ofenwagenzügen erforderlich, um eine Sandzuführung zur dort befindlichen Sandrinne zu ermöglichen. Wie sich herausgestellt hat, ist dies in bezug auf die Strömungsverhältnisse im Brennkanal ungünstig. Zudem vermehrt die Vielzahl von Sandrinnen bei mehrsträngigem Betrieb die ohnehin schon vorhandenen Undichtigkeiten zwischen Brennkanal und Unterwagenkanal und führt zu Problemen in der Aufheizzone des Ofens. Mehrsträngige Tunnelöfen ohne Zwischenwände werden deshalb seit längerem nicht mehr gebaut.It is known that several kiln car trains run in parallel next to each other without partitions Drive through a multi-strand tunnel kiln. The kiln car are equipped with sand aprons on their long sides, thaw the channels filled with sand in the furnace foundation to seal the undercarriage duct. There is a larger distance between the kiln car trains required to have a sand feed to the one located there Allow sand channel. As it turns out has, this is in relation to the flow conditions unfavorable in the combustion channel. In addition, the variety increases of sand gutters in multi-strand operation anyway existing leaks between the combustion channel and undercarriage channel and leads to problems in the Heating zone of the furnace. Multi-strand tunnel kilns without Partitions have therefore not been used for a long time built.

Der Erfindung liegt die Aufgabe zugrunde, den Tunnelofen so auszubilden, daß ihn Ofenwagen entsprechend dem Hauptpatent auch mit zwei oder mehr Zügen parallel nebeneinander ohne Zwischenwände durchlaufen können und auch bei diesem mehrsträngigen Ofenbetrieb Undichtig­ keiten zwischen Unterwagenkanal und Brennkanal weitest­ gehend ausgeschlossen sind. The invention has for its object the tunnel kiln to be trained so that it corresponds to the kiln car Main patent with two or more trains in parallel can walk side by side without partitions and also leaky in this multi-strand furnace operation as far as possible between the undercarriage duct and the combustion duct are excluded.  

Diese Aufgabe wird durch die im Patentanspruch gekenn­ zeichneten Merkmale des Tunnelofens gelöst.This object is characterized by the claim characteristics of the tunnel kiln solved.

Der Vorteil dieser Ausbildung des Fundaments besteht darin, daß nunmehr bei einem mehrsträngigen Tunnelofen ohne Zwischenwände eine nahezu vollkommene Abdichtung erreicht und der Abstand zwischen benachbarten Wagenzügen gering gehalten werden kann. Außerdem können die bei älteren, mehrsträngigen Tunnelöfen üblichen schmalen Ofenwagen mit einfacher Umrüstung wieder verwendet werden.The advantage of this formation of the foundation is in that now with a multi-strand tunnel kiln an almost complete seal without partition walls reached and the distance between neighboring wagon trains can be kept low. In addition, at older, multi-strand tunnel kilns usual narrow Kiln car reused with simple retrofitting will.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und nachstehend beschrieben.An embodiment of the invention is in the drawing shown and described below.

Zwei oder mehr aus dicht aneinander anschließenden Ofenwagen bestehende Ofenwagenzüge 2 werden gleisgebunden parallel nebeneinander durch den mehrsträngigen Tunnel­ ofen 1 gefahren, wobei die Ofenwagen eng entlang den Ofenseitenwänden 5 laufen, wodurch oberhalb der Züge ein Brennkanal 9 und unterhalb derselben ein Unterwagen­ kanal 8 sich bildet. Die Ofenwagen sind an ihren Stirn­ seiten mit Schürzen 4 versehen, die gegen die Ofenwände 5 bzw. einen Sockel 6 schleifen und mit allenfalls geringen Abstand zum Ofenfundament 7 herabreichen, so daß eine Längsströmung im Unterwagenkanal 8 im Aufheizbereich des Ofens 1 unterbunden wird. Der Sockel 6 verläuft längs des Ofens 1 zwischen zwei Wagenzügen 2 und ragt vom Fundament 7 des Ofens 1 etwa in der Höhe des Unterwa­ genkanals 8 nach oben.Two or more kiln car trains 2 consisting of closely adjoining kiln cars are run parallel to each other through the multi-strand tunnel kiln 1 , the kiln cars running closely along the side walls of the kiln 5 , whereby a combustion channel 9 forms below the trains and an undercarriage channel 8 below them. The kiln cars are provided on their faces with aprons 4 , which grind against the kiln walls 5 or a base 6 and reach down at most a small distance from the kiln foundation 7 , so that a longitudinal flow in the undercarriage channel 8 in the heating area of the kiln 1 is prevented. The base 6 runs along the furnace 1 between two wagon trains 2 and protrudes from the foundation 7 of the furnace 1 approximately at the height of the Unterwa genkanals 8 .

Die Unterwagenkühlung erfolgt entsprechend dem Hauptpatent in einem höchstens ab Mitte der Brennzone über die Kühlzone des Ofens (nicht dargestellt) sich erstreckenden Kühlbereich.The undercarriage is cooled according to the main patent in a at most from the middle of the firing zone over the Cooling zone of the furnace (not shown) extending Cooling area.
