Abstract

Bei einer Vorrichtung zum Verbrennen von Kohlen­ staub mit einer in eine Nachverbrennungskammer (7) hin­ einreichende Primärflamme (3), welcher der Kohlenstaub beigemischt wird, soll die Verbrennung des Kohlenstaubes und die Entfernung dar Rückstände verbessert werden. Die Nachverbrennungskammer (7) besteht aus einem Ring­ kanal (6) dessen Ringachse (32) vertikal und quer zur Achse der Primärflamme verläuft. An beiden Stirnseiten des Ringkanals (6) ist je eine Austrittsöffnung (11; 12) vorgesehen. Ein den Ringkanal (6) koaxial durchsetzendes und beidseitig überstehendes Innenrohrstück (13) mit Durchbrüchen (25) beeinflußt die Verweildauer der Flamm­ gase im Ringkanal. In a device for burning coal dust with into a post-combustion chamber (7) Submitting primary flame (3), which is the coal dust is added, the combustion of the coal dust and the removal of the residues is improved. The afterburning chamber (7) consists of a ring channel (6) whose ring axis (32) vertically and transversely to The axis of the primary flame runs. On both faces the annular channel (6) has an outlet opening (11; 12) intended. A coaxially penetrating the ring channel (6) and inner tube piece (13) projecting on both sides with Breakthroughs (25) affect the residence time of the flame gases in the ring channel.
