Abstract

Zum Entfernen von Ablagerungen in Zuführungsdüsen (20), die zur Rückführung von Abgas in den Feuerraum einer Feuerungsanlage dienen, ist eine Lanze (27) in die Zuführungsdüsen (20) einsetzbar, die in ihrer Längsrichtung verschiebbar gehalten ist. Die Lanze (27) weist an ihrem vorderen Ende einen Düsenkopf (28) zum Aussprühen von Wasser auf und ist an ihrem hinteren Ende mit einer Ventileinrichtung (29) verbunden, die über eine Regeleinrichtung (32) hinsichtlich der Wassermenge, des Wasserdruckes und der Öffnungs- und Schließzeiten einstellbar ist. Mit Hilfe der Lanze (27) wird Wasser auf Ablagerungen (34) im Inneren der Zuführungsdüse (20) in feiner Verteilung aufgesprüht, wodurch das Wasser in diese Ablagerungen eindringt und durch Dampfentwicklung ein Absprengen dieser Ablagerungen bewirkt.
