Aus WO 95/1833 ist ein Schub-Verbrennungsrost-Modul zum Verbrennen von Kehricht in Großanlagen sowie ein Verfahren zu dessen Betreiben bekannt, bei dem Rostplatten übereinanderliegend angeordnet sind, wobei die Rostplatten seitlich durch Planken begrenzt sind, die aus Vierkantprofilen bestehen und durch die Zu- und Ableitungen für das Kühlen der Rostplatten verlaufen können. Die Verbrennungsroste sind einbahnig ausgeführt. Bei einer mehrbahnigen Ausführung von Verbrennungsrosten sind statt der Planken die vorgeschlagenen fluidgekühlten Mittelbalkenelemente einsetzbar, so daß eine seitliche Trennung einer jeden Rostbahn zur Nachbarrostbahn entsteht. Diese Trennung ermöglicht eine unterschiedliche Fahrweise benachbarter Rostbahnen, wenn die dafür eingesetzte Installation der Rostbahnen mechanisch und lufttechnisch entkoppelt ist. Dazu werden Bauteile eingesetzt, die fest mit der Unterkonstruktion des Verbrennungsofens verbunden sind und bis in den Feuerungsraum hineinreichen. Sofern mehr als zwei Rostbahnen nebeneinander angeordnet sind, kann diesen Bauteilen auch die Aufgabe der Aufnahme von Längenänderungen über die Rostbahnbreite infolge von Temperaturänderungen zugeordnet werden. From WO 95/1833 is a thrust combustion grate module for burning of garbage in large plants and a method for operating it is known in which grate plates are arranged one above the other, wherein the grate plates are laterally limited by planks made of square profiles exist and through the supply and discharge lines for cooling the grate plates can run. The combustion grates are single lane. at a multi-lane version of combustion grates are instead of Planks the proposed fluid-cooled central beam elements can be used, so that a lateral separation of each grate track Neighboring rust railway is created. This separation enables a different one Operation of neighboring grate tracks if the installation used for this the grate tracks are decoupled mechanically and in terms of ventilation. To do this Components used that are fixed to the substructure of the Incinerator are connected and up to the furnace extend.

Der in Fig. 1 gezeigte Mittelbalken besteht aus einzelnen
Mittelbalkenelementen 15, die je nach Länge des Mittelbalkens
hintereinander aufgebaut werden können und in der vorliegenden
Ausführungsform in Reihe geschaltet sind. Ein Mittelbalkenelement 15
besteht aus zwei glockenförmig übereinander gestülpten, einseitig offenen
Hohlkörpern, von denen das Innenteil 1 und das Außenteil 2 unterschieden
werden. Beide Teile, aus Guss bestehend, werden einzeln gegossen und
dann zusammengefügt. Auf der Außenfläche des Innenteiles 1 sind Rippen 3
angeordnet, die nach dem Aufsetzen des Außenteiles 2 die Begrenzung der
Kühlkanäle (a, b) bilden und den Verschluss des gesamten Hohlraumes für
die Aufnahme des Kühlmediums gewährleisten. Die Rippen 3 des Innenteiles
1 sind so angeordnet, dass sich hinter der Einströmöffnung 4 Kanäle (a, b)
auf beide Seiten des Innenteiles 1 aufteilen und erst auf der Auslaufseite 5
wieder zusammengeführt sind, um in einer weiteren zweiten Ebene wieder
gegenläufig aufgeteilt zu werden, um auf der Einlaufseite wieder
zusammenzutreffen. Von dort wieder gegenläufig geführt, werden die
Strömungen auf der obersten Ebene zur Auslaufseite 5 geführt, wo sie als
eine Strömung in das Auslaufrohr 7 münden. Das Auslaufrohr 7 ist zur
Mitnahme von Luftblasen bis an die oberste Stelle im Hohlraum geführt und
