unter die Rostplatte zugeführte Gas. Erfindungsgemäß sind dabei die Rostplattenkörper so
in den Rostplattenrahmen angeordnet, daß an der
in Förderrichtung des Materials gesehenen Vorderseite der Rostplatte terrassenförmig
versetzt mehrere Horizontalschlitze angeordnet sind. Die Spaltweite der Horizontalschlitze
wird durch die an der Oberseite der Rostplattenkörper angegossene Abstandshalter
bestimmt.
Die in die Rostplatten eingesetzten Rostplattenkörper sind entsprechend den
erforderlichen thermischen Bedingungen und dem Förderverhalten des Materials
verschiedenartig ausgebildet. Zum Einsatz kommen Rostplattenkörper mit eben
ausgebildeter Oberfläche oder Rostplatten, die in Förderrichtung des Materials gesehen im
vorderen Bereich mit einer nach oben gerichteten Schräge versehen sind. Durch die
unterschiedliche Anordnung von verschiedenartig gestalteten Rostplattenkörpern in einer
Rostplatte, des Einsatzes von unterschiedlich ausgeführten Rostplatten in einer
Rostplattenreihe und durch Änderung der Anzahl der Rostplattenkörper unter Beibehaltung
der Grundform der Rostplatten wird erreicht, daß die Gase mit unterschiedlichen
Gasmengen und unter einem unterschiedlichen Austrittswinkel dem Material zugeführt
werden.Each grate plate is box-shaped and has gas outlet slots for the gas supplied under the grate plate. According to the invention, the grate plate bodies are arranged in the grate plate frame in such a way that a plurality of horizontal slots are arranged offset on the front side of the grate plate as seen in the conveying direction of the material.

2 ist unterschiedlich gestaltet und richtet sich
nach dem Förderverhalten und den Kühlbedingungen
des Materials. Durch den Einsatz von Rostplattenkörpern
2 mit eben ausgebildeter Oberfläche - wie in Figur
1 dargestellt - wird erreicht, daß die Kühlluft eine längere
Zeit zum Durchströmen der Materialschicht wie beispielsweise
gegenüber einer Querströmung benötigt.
Dadurch ist der Wärmetausch zwischen Kühlluft und heißem
Material intensiver. Gleichzeitig wird eine Verstopfung
der Horizontalschlitze 3 durch Material weitestgehend
vermieden.The shape of the grate plate body used

beeinflußt. Der Winkel der Schräge beträgt 10° bis 40°
und ist abhänig von den benötigten erforderlichen Gasaustrittsbedinungen.
Die Anzahl der Rostplattenkörper
2 einer Rostplatte 6 kann bis zu 7 betragen und richtet
sich nach der benötigten Luftmenge. Im Randbereich
der Rostkühleroberfläche werden Rostplatten 6 mit einer
geringen Anzahl von Horizontalschlitzen 3 eingesetzt,
da im Randbereich gegenüber dem mittleren Bereich ein
geringerer Gasdurchsatz benötigt wird.Through the use of
