Abstract

Luftdüse (1) zum Einbringen eines ein Oxidationsmittel umfassenden Gasstroms in einen Feuerraum, umfassend:
- einen Düsenfinger (2) mit mindestens einer Gasstromzuführung (3) und mindestens einer Gasstromausführung (4);
- eine Düsenhaube (7) zum Überdecken des Düsenfingers (2) zumindest im Bereich der mindestens einen Gasstromausführung (4) mit mindestens einem Loch (14) in der Außenhülle zum Ausleiten des Gasstroms;

wobei Düsenfinger (2) und Düsenhaube (7) durch eine gewindefreie Klemmverbindung lösbar miteinander verbindbar sind, wobei das mindestens eine Loch (14) mit der mindestens einen Gasstromausführung (4) in strömungstechnischer Verbindung steht, wenn Düsenfinger (2) und Düsenhaube (7) miteinander verbunden sind.
Die erfindungsgemäße Luftdüse (1) erlaubt es in vorteilhafter Weise, bei guten strömungstechnischen Eigenschaften und einem geringen Verschleiß, Luft als einen ein Oxidationsmittel umfassenden Gasstrom in einen Feuerraum insbesondere einer Wirbelschichtfeuerung einzubringen. Gleichzeitig lässt sich die Düsenhaube (7) einfach reversibel vom Düsenfinger (2) trennen, die Luftdüsen (1) können so einfach inspiziert, gewartet und ausgetauscht werden.
