Abstract

Gemäss dem Verfahren wird die durch den Schubverbrennungsrost auf das Brennbett zugeführte Primärluft nach dem Austritt aus der Schubrost-Oberfläche mittels auf der Schubrost-Oberfläche befestigter Leitelemente (10) umgelenkt. Der dazu nötige Rost besteht aus Rostplatten (1-4), die aus einem durchströmbaren Hohlkörper mit AnschlussStutzen für die Zu- und Abfuhr von Kühlwasser bestehen, sowie von unten nach oben die Rostplatte durchsetzende Primärluft-Zuführkanäle (9) aufweisen. Ueber den Mündungen der Primärluft-Zufuhrkanäle (9) sind Leitelemente (10) angeordnet, auf welche die aus der Mündung austretende Primärluft aufzutreffen bestimmt ist.
