Abstract

Tunnel kiln (1) with wagons running through in the form of a tightly closed wagon train (2), on the end faces of which wagons there are arranged sealing skirts (4) which extend downwards, brush against the kiln walls (5), have at the most a small separation from the base (7) of the tunnel kiln and form sections of the under-wagon channel (8) along the length of the kiln. With the arrangement of two or more wagon trains (2) parallel next to one another along the tunnel kiln (1), there projects upwards between two wagon trains (2), from the base (7) of the kiln and corresponding approximately to the height of the under-wagon channel (8), a plinth (6), against which the skirts (4) brush. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Tunnelofen entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a tunnel kiln according to the preamble of claim 1.

Ein Tunnelofen dieser Art ist Gegenstand der europäischen Anmeldung 87102005.3 (EP-A-237791), wonach der Tunnelofen einsträngig ist, das heißt, nur einen Fahrstrang für einen Ofenwagenzug hat.A tunnel kiln of this type is the subject of European application 87102005.3 (EP-A-237791), according to which the tunnel kiln is single-stranded, that is to say has only one drive train for a kiln car train.

Es is bekannt, daß mehrer 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 eintauchen, um eine Dichtung zum Unterwagenkanal zu schaffen. Dabei ist ein größerer Abstand zwischen den Ofenwagenzügen erfoderlich, 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 Vielzhal 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 pass through a correspondingly multi-strand tunnel kiln in parallel next to one another without partition walls. On their long sides, the kiln cars are equipped with sand aprons, which dip into channels filled with sand in the kiln foundation to create a seal to the undercarriage channel. This requires a greater distance between the kiln car trains to allow sand to be fed to the sand channel located there. As has been found, this is unfavorable in relation to the flow conditions in the combustion channel. In addition, the multitude of gullies increases the already existing leaks between the combustion duct and the undercarriage duct in multi-strand operation and leads to problems in the heating zone of the furnace. Multi-strand tunnel kilns without partition walls have therefore not been built for a long time.

Der Erfindung liegt die Aufgabe zugrunde, den Tunnelofen so auszubilden, daß ihn Ofenwagen auch mit zwei oder mehr Zügen parallel nebeneinander ohne Zwischenwände durchlaufen können und auch bei diesem mehrsträngigen Ofenbetrieb Undichtigkeit zwischen Unterwagenkanal und Brennkanal weitestgehend ausgeschlossen sind.The invention has for its object to design the tunnel kiln so that kiln cars can run through it with two or more trains in parallel next to each other without partitions and even in this multi-line kiln leakage between the undercarriage duct and the combustion duct are largely excluded.

Diese Aufgabe wird durch die im Patentanspruch gekennzeichneten Merkmale des Tunnelofens gelöst.This object is achieved by the features of the tunnel oven characterized in the claim.

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 that now with a multi-strand tunnel furnace without partitions an almost perfect seal is achieved and the distance between adjacent wagon trains can be kept small. In addition, the narrow kiln cars common to older, multi-strand tunnel kilns can be reused with simple retrofitting.

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

Zwei oder mehr aus dicht aneinander anschließenden Ofenwagen bestehende Ofenwagenzüge 2 werden gleisgebunden parallel nebeneinander durch den mehrsträngigen Tunnelofen 1 gefahren, wobei die Ofenwagen eng entlang den Ofenseitenwänden 5 laufen, wodurch oberhalb der Züge ein Brennkanal 9 und unterhalb derselben ein Unterwagenkanal 8 sich bildet. Die Ofenwagen sind an ihren Stirnseiten mit Schürzen 4 versehen, die gegen die Ofenwände 5 bzw. einen Sockel 6 schleifen und mit allenfalls geringem 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 Unterwagenkanals 8 nach oben.Two or more kiln car trains 2 consisting of closely adjoining kiln cars are run parallel to one another 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 above the trains and an undercarriage channel 8 below them. The furnace trolleys are provided on their end faces with aprons 4, which grind against the furnace walls 5 or a base 6 and reach down at most a short distance from the furnace foundation 7, so that a longitudinal flow in the undercarriage duct 8 in the heating region of the furnace 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 undercarriage duct 8.

Die Unterwagenkühlung erfolgt in einem höchstens ab Mitte der Brennzone über die Kühlzone des Ofens (nicht dargestellt) sich erstreckenden Kühlbereich.The undercarriage is cooled in a cooling area which extends at most from the middle of the firing zone over the cooling zone of the furnace (not shown).

Claims (1)

  1. Tunnel kiln with a firing channel above the kiln cars, formed by the kiln cars narrowly passing at the side walls of the tunnel and an under car channel, arranged below the kiln cars, as well as with baffles arranged at the kiln cars, which are installed at the front side of at least one of the neighbouring kiln cars, sliding against the kiln walls and at most at a little distance to the foundation and forming sections of the under car channel in the length of the kiln car,
    characterized by that,
    that at the arrangement of two or more trains of kiln cars (2) alongside the tunnel kiln (1) beween two trains (2) a base (6) rising from the floor of the foundation, is arranged approximately corresponding to the heigth of the under car channel (8), against which the baffles (4) are sliding.
