Abstract

Die Erfindung betrifft eine Vorrichtung zum Verbrennen, insbesondere von reaktionsträgem Kohlenstaub, mit axialer Zuführung des Kohlenstaubs und mit einer Dralleinrichtung für die Verbrennungsluft am vorderen Ende einer Verbrennungs- und Beschleunigungskammer, an deren Innenwand das Kohlenstaub-Luft-Gemisch eine schraubenlinienförmige Bewegung vollführt, sowie mit einer Ascheaustragsöffnung in der Wand der Verbrennungs- und Beschleunigungskammer. Sie ist dadurch gekennzeichnet, daß die Wand der Verbrennungs- und Beschleunigungskammer (11) axial oder im wesentlichen axial gerichtete schmale, in Umfangsrichtung der Kammer aufeinanderfolgende Längsschlitze (20) aufweist. The invention relates to a device for burning, especially of inert coal dust, with axial feeding of the coal dust and with a Swirl device for the combustion air at the front End of a combustion and acceleration chamber the inner wall of the coal dust-air mixture helical movement performed, as well as with an ash discharge opening in the wall of the combustion and acceleration chamber. It is characterized by that the wall of the combustion and acceleration chamber (11) axially or substantially axially directed narrow, successive in the circumferential direction of the chamber Has longitudinal slots (20).
