Description

Zum Anzünden von Kohlenstaubfenerungen hat man :bisher meist Ölbrenner benutzt. Um Öl zu sparen, hat man auch schon vorgeschlagen, den Staubselber zum Zünden zu benutzen. Der Staub wurde in einem besonderen Zündbrenner zur Entzündung gebracht und der Zündbrenner so angeordnet, daß die Zündflamme den Weg des Kohlenstaubluftgemisches des bzw. der Hauptbrenner kreuzt. Um den Staub in dem Zündbrenner zur Entflammung zu bringen und ein Wiederabreißen der Zündflamme zu verhindern, hat man in dem Zündbrenner eine in Glut befindliche Wandung angeordnet, an der der Kohlenstaubluftstrom zwecks Erhitzung und Entzündung entlang geführt wurde.To light coal dust you have: so far mostly oil burners used. In order to save oil, it has already been suggested to use the dust self To use ignition. The dust was ignited in a special pilot burner brought and the pilot burner arranged so that the pilot flame the path of the pulverized coal air mixture the main burner (s) crosses. To get the dust in the pilot burner to ignite to bring and to prevent the pilot flame from tearing off again, one has in the pilot burner a wall located in embers is arranged on which the coal dust air flow for the purpose Heating and inflammation was passed along.

Die Erfindung besteht darin, die Wandung durch elektrische Beheizung zum Glühen zu bringen. Dies vereinfacht die Inbetriebsetzung der Koblenstaubfeuerung. Auch kann .der Zündbrenner an verhältnismäßig unzugänglichen Stellen untergebracht werden, ohne @daßdadurch Schwierigkeiten bei der Inbetriebsetzung entstehen. Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindung s.gegenstandes.The invention consists in the wall by electrical heating to glow. This simplifies the start-up of the dust furnace. The pilot burner can also be housed in relatively inaccessible places without @ causing difficulties during commissioning. the Drawing shows an embodiment of the invention see subject.

Unter dem Hauptbrenner a liegt der Zündbrenner b, dessen Rohr ä durch die Leitung h ein Staubluftgemisch zugeführt wird. Das Rohr g wird von außen durch eine elektrische, beispielsweise Widerstandsheizung fzum Glühen gebracht, so daß der durchfließende Staubluftstrom zündet. Die Zündflamme kreuzt den Staubluftstrom des Hauptbrenners a und bringt diesen zur Entflammung. Sobald der Feuerraum genügend heiß geworden ist, so daß ein Abreißender Flamme nicht mehr zu befürchten ist, kann der Zündbrenner stillgesetzt werden. The pilot burner b is located under the main burner a, the tube of which a dust air mixture is fed through the line h. The tube g is made to glow from the outside by an electrical, for example resistance heating f, so that the dusty air stream flowing through ignites. The pilot flame crosses the dust air flow of the main burner a and causes it to ignite. As soon as the combustion chamber has become sufficiently hot that there is no longer any risk of the flame breaking off, the pilot burner can be shut down.
