Description

Tunnelofen mit über die ganze Länge der Brennzone nebeneinander ausgeteilten, von den Stirnseiten her zugänglichen Regeneratoren Bei den Tunnelöfen, wie sie z. B. zum Brennen feuerfester SteineAnwendung finden, hat man zur Erzielung der erforderlichen hohen und gleichmäßigen Temperatur in der Brennzone eine im jeweiligen zeitlichen Wechsel quer durch bzw. über den Tunnelraum erfolgende Regenerativbelieizung vorgesehen. Zur Erzielung einer gleichmäßigen Beheizung des Brenngutes ist es von Wert, eine große Anzahl von Gas- und Luftdüsen nebeneinander in der Längsrichtung des Tunnels anzuordnen. Zu diesem Zwecke ist es erforderlich, die Gas- und Luftkammern je mit einer Anzahl von Zweigkanälen zu versehen. Eine besonders zweckmäßige Ausführung dieser Art bildet den Gegenstand der Erfindung.Tunnel furnace with side by side distributed over the entire length of the firing zone, regenerators accessible from the front sides. B. for burning refractory bricks use, you have to achieve the required high and uniform temperature in the firing zone one at a time Renewable lighting is provided to change across or across the tunnel space. In order to achieve even heating of the items to be fired, it is of value to have a large number of gas and air nozzles side by side in the longitudinal direction of the tunnel to arrange. For this purpose it is necessary to have the gas and air chambers each to provide a number of branch channels. A particularly useful design this type forms the subject of the invention.

Dabei ist von der bekannten Anordnung ausgegangen, bei der die Regeneratorpaare so nebeneinander angeordnet sind, daß alle über die Brennzone verteilten Kammern von der Stirnseite zugänglich sind, so daß sie erforderlichenfalls gereinigt und in bezug auf das Gitterwerk einer Erneuerung unterworfen werden können. Gemäß der Erfindung werden mit den Oberteilen solcher Regeneratoren in Verbindung stehende, parallel zur Tunnelachse verlaufende Verteilkanäle vorgesehen, an die wechselweise die nebeneinanderliegenden, quer dazu verlaufenden Gas- und Luftzuführungskanäle anschließen. Damit wird im Ofen selbst eine ununterbrochene Folge von miteinander abwechselnden Gas- und Luftdüsen erzielt, durch die eine sich praktisch über die ganze Brennzone erstreckende Flamme gewährleistet wird.This is based on the known arrangement in which the regenerator pairs are arranged side by side in such a way that all chambers are distributed over the combustion zone are accessible from the front, so that they can be cleaned and if necessary with respect to the latticework can be subject to renewal. According to the Invention are associated with the tops of such regenerators, Distribution channels running parallel to the tunnel axis are provided to which alternately the adjacent, transverse gas and air supply ducts connect. This creates an uninterrupted sequence of each other in the furnace itself alternating gas and air nozzles achieved through which one practically over the the entire combustion zone is guaranteed to extend the flame.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in Abb. i im Grundriß, in Abb. 2 im Querschnitt und in Abb. 3 im Längsschnitt wiedergegeben.The drawing shows an exemplary embodiment of the subject matter of the invention in Fig. i in plan, in Fig. 2 in cross section and in Fig. 3 in longitudinal section.

Über die ganze Länge der Brennzone des Tunnelofens io sind abwechselnd die Gas-und Luftregeneratoren ii und i2 angeordnet, von denen je zwei nebeneinanderliegende an einen der sich gabelnden Zuführungskanäle 13 und 14. angeschlossen sind. Die in dem feuerfesten Gitterwerk vorgewärmten Verbrennungsmittel treten in die Verteilkanäle 15, 16 ein, die nebeneinanderliegen und sich über ein zusammengehöriges Paar der Regeneratoren 11, 12 erstrecken. Die Zuführungskanäle 17, 17 für Gas und 18, 18 für Luft erstrecken sich wiederum quer zu den Verteilkanälen 15, 16 und sind derart abwechselnd angeordnet, daß jeweilig an der Austrittsstelle im Tunnelofen oder den Austrittsstellen eine ununterbrochene abwechselnde Folge von Gas- und Luftdüsen vorhanden ist. Durch Sehieberchen i9, die von den Schau- und Bedienungsöffnungen 2o aus eingestellt werden können, können die einzelnen Übertrittsöftnungen aus den Kanälen 15 bzw. 16 in die Kanäle 17 bzw. 18 geregelt werden.Over the entire length of the combustion zone of the tunnel kiln io are alternating the gas and air regenerators ii and i2 are arranged, two of which are adjacent to each other are connected to one of the bifurcating supply channels 13 and 14. the Combustion agents preheated in the refractory latticework enter the distribution channels 15, 16, which are located next to each other and via a related pair of Extend regenerators 11, 12. The supply channels 17, 17 for gas and 18, 18 for air again extend transversely to the distribution channels 15, 16 and are of this type arranged alternately that each at the exit point in the tunnel furnace or the Exit points an uninterrupted alternating sequence of gas and air nozzles is available. Through little eyelids from the viewing and service openings 2o off can be set, the individual transfer openings from the Channels 15 and 16 are regulated into channels 17 and 18, respectively.

Die über .den Regeneratoren liegenden Verteilkanäle werden damit gleichzeitig Ausgleichskanäle und bewirken zunächst eine gleichmäßige Grundverteilung der Verbrennungsmittel über die jeweilige Länge eines Regeneratorpaares,womit eine Unabhängigkeit von den durch Unregelmäßigkeiten des feuerfesten Gitterwerks bedingten ungleichmäßigen Strömungen der Gase geschaffen wird. Die anschließende Feinverteilung durch die schiebergeregelten Anschlüsse gestattet darüber hinaus eine genaue Einstellung der Brennkurve. Da die ganze obere Kanalgruppe in einer hohen Temperaturzone liegt und eine innige Berührung der störenden Gase mit den Wandungen der engen Kanäle stattfindet, erfolgt ein nicht unwesentlicher Teil des Wärmeaustausches in diesen Kanälen. Für die eigentlichen Regeneratoren kann man daher mit einer geringeren Höhe auskommen.The distribution channels lying above the regenerators are thus simultaneously Compensating channels and initially cause an even basic distribution of the combustion agent over the respective length of a regenerator pair, which means that it is independent of the uneven flows caused by irregularities in the refractory latticework of gases is created. The subsequent fine distribution by the slide controlled Connections also allow precise setting of the firing curve. Since the whole upper channel group lies in a high temperature zone and an intimate contact the interfering gases with the walls of the narrow channels takes place, there is no insignificant part of the heat exchange in these channels. For the real Regenerators can therefore get by with a lower height.
