Description

Verfahren und Vorrichtung zum Brennen von Method and device for burning

Mauerziegeln mit Festbrennstoff Technisches Gebiet Bei der Erfindung handelt es sich um das Brennen von Mauerziegeln mit Festbrennstoffen in Tunnelöfen. Solid fuel masonry bricks Technical Field In the invention it concerns the burning of masonry bricks with solid fuel in tunnel kilns.

Stand der Technik Es ist das Verfahren nach Europäischer Patentanmeldung O 059 986 zum Brennen von insbesonders Tondachziegeln mit Festbrennstoffen bekannt. Dabei werden Kassetten mit senkrechten Schenkeln zum Brennen übereinander gestapelt da das Brenngut wenig standfest ist.State of the art It is the method according to the European patent application O 059 986 for burning clay roof tiles in particular with solid fuels is known. Cassettes with vertical legs are stacked on top of each other for burning because the material to be fired is not very stable.

Für das Brennen von standfesten Mauerziegeln ist dieses Verfahren aufwendig und nicht erforderlich. Andere Verfahren der direkten Ofenbeheizung mit Festbrennstoffdn oder der externen Gaserzeugung führen zu unbefriedigenden Resultaten bzw. zu schlechteren Wirkungsgraden. hVetj:a1ren und Vorrichtung .....This method is used for firing stable masonry bricks expensive and not required. Other methods of direct furnace heating with Solid fuel or external gas generation lead to unsatisfactory results or to poorer efficiencies. hVetj: a1ren and device .....

Es wurden Versuche unternommen, in Tunnelöfen die freien Längs- oder Querschlitze der Brennwagen mit Kohle zu beschütten. Diese Methode hat den Nachteil, daß der Brennstoff und besonders die Asche an diesen Stellen infolge der Strömungen in den Öfen verweht wird, was zur Brenngutverschmutzung führt.Attempts have been made in tunnel ovens the free longitudinal or To fill the cross slots of the kiln car with coal. This method has the disadvantage that the fuel and especially the ash in these places as a result of the currents is blown away in the ovens, which leads to soiling of the kiln.

Die Erfindung Aufgabe der Erfindung ist es ein Verfahren und Vorrichtungen anzugeben, die ein sauberes und wirtschaftliches Brennen von standfesten Mauerziegeln mit Festbrennstoffen erlaubt.The invention The object of the invention is a method and devices indicate the clean and economical firing of stable masonry bricks allowed with solid fuel.

Das neue Verfahren soll mit den bekannten Tunnelöfen durchführbar sein und Anlage und Produkt frei von Ascheresten halten. Außerdem soll eine Beschleunigung des Brandes und bessere Temperaturgleichheit im Ofen erreicht werden. Ferner soll verhindert werden, daß Brennstoff oder Asche das Brenngut oder die Brennwagen verschmutzen kann.The new process should be feasible with the known tunnel kilns and keep the system and product free from ash residues. In addition, an acceleration of the fire and better temperature uniformity in the furnace can be achieved. Furthermore should fuel or ash can be prevented from contaminating the items to be fired or the firing trolleys can.

Die Lösung der Aufgabe erfolgt dadurch, daß die Mauerziegel in mehreren Lagen und erforderlichenfalls im Verband auf einen Hohlrost gesetzt werden, welcher sich auf dem Brennwagendeck befindet. Die Hohlroststeine werden dabei mit Festbrennstoff gefüllt, bevor die getrockneten Mauerziegel darauf gesetzt werden.The solution to the problem is that the bricks in several Layers and, if necessary, placed in a dressing on a hollow grid, which is on the kiln car deck. The hollow grate stones are made with solid fuel filled before the dried masonry bricks are placed on top.

Damit entsteht ein weitgehend selbstbrennender Brennwagenbesatz der von unten beheizt wird, von dort wo der größte Wärmebedarf herrscht wegen des mitzuerwärmenden Brennwagendecks. Die Erwärmung des Besatzes von unten ist wegen der natürlichen Auftriebskräfte in der Anwärmzone des Ofens deshalb besonders effektiv.This creates a largely self-burning kiln car set of the is heated from below, from where the greatest heat demand is due to the need to be heated Brenn wagon decks. The warming of the trimmings from below is because of the natural Buoyancy forces in the heating zone of the furnace are therefore particularly effective.

Die Einzelnen Hohlrostelemente bestehen im wesentlichen aus mit Vertiefungen versehenen Körpern welche z.B. nach oben offen sind und in die vor dem Brand Festbrennstoff eingefüllt wird. Das Einfüllen von Festbrennstoff und das Entaschen kann auf dem Brennwagen vorgenommen werden. gorteil- Verfahren und Vorrichtung .......The individual hollow grate elements essentially consist of recesses provided bodies which, for example, are open at the top and in which solid fuel was used before the fire is filled. Filling with solid fuel and removing ash can be done on the Brennwagen can be made. gorteil- Method and device .......

hafterweise wird aber der Hohlrost abschnittsweise samt den darauf gesetzten Mauerziegelstapeln vom Brennwagen abgenommen und auf einer separaten Umlaufbahn entladen, entascht, neu bekohlt und wieder mit getrockneten Formlingen besetzt. Charakteristisch beim erfindungsgemäßen System ist, daß die Hohlrostelemente vom Ziegelbesatz abgedeckt werden, sodaß durch die Ofenströmungen kein Festbrennstoff oder Asche aus denselben herausgeblasen werden kann. Die Erfindung ist an Hand beigefügter Zeichnungen beispielhaft dargestellt.However, the hollow grating is liable to be broken up in sections together with the ones on it The set stacks of masonry bricks are removed from the kiln car and placed on a separate orbit Discharged, deashed, re-charred and filled again with dried bricks. It is characteristic of the system according to the invention that the hollow grate elements from Bricks are covered so that no solid fuel through the furnace currents or ashes can be blown out of them. The invention is attached with reference Drawings shown by way of example.
