Abstract

Die Erfindung berifft eine Brennereinheit für staubförmigen Festbrennstoff mit einem ersten Rohr (3) zur Förderung des Festbrennstoffes in einer ersten Förderrichtung, wobei in Verlängerung des ersten Rohrs (3) ein Umlenkkörper (4) zur Umlenkung des aus dem ersten Rohr (3) austretenden Festbrennstoffstrahls angeordnet ist. Erfindungsgemäß ist die Brennereinheit dadurch gekennzeichnet, dass das erste Rohr (3) einen das erste Rohr umgebenden Prallkörper (7) aufweist, welcher den durch den Umlenkkörper (4) umgelenkten Festbrennstoffstrahl im Wesentlichen in die erste Förderrichtung wieder umlenkt. Ferner betrifft die Erfindung eine Brenneranordnung (X) für einen Ofen, insbesondere einen Ringschachtofen zum Brennen von Kalkstein, mit einer solchen Brennereinheit.

The invention relates to a burner unit for dusty solid fuel having a first tube (3) for conveying the solid fuel in a first conveying direction, wherein in extension of the first tube (3) a deflecting body (4) for deflecting the solid fuel jet emerging from the first tube (3) is arranged. According to the invention, the burner unit is characterized in that the first tube (3) has a baffle body (7) surrounding the first tube which deflects the solid fuel jet deflected by the deflecting body (4) substantially in the first conveying direction again. Furthermore, the invention relates to a burner assembly (X) for a furnace, in particular a ring-shaft furnace for burning limestone, with such a burner unit.
