•Verfahren zum Zünden einer Kohlenstaub-Rundbrenner flamme "• Procedure for igniting a pulverized coal burner flame "

Die Erfindung betrifft ein Verfahren zum Zünden einer Kohlenstaub-Rundbrennerflamme mit internem Rückstromgebiet, bei der die Zündenergie zentral in das interne Rückstromgebiet der Kohlenstaub-Rundbrennerflamme eingebracht wird.The invention relates to a method for igniting a coal dust circular burner flame with an internal return flow area, in which the ignition energy is introduced centrally into the internal return flow area of the pulverized coal burner flame will.

Es ist bereits vorgeschlagen worden, daß das Staublauft-Staubgewichtsverhältnis für die Staubzündflamme kleiner (o,5 - l,o) als das der Hauptbrennerflamme (1,5 - 2,o) ist. Es ist ferner vorgeschlagen, daß die Staubzündflamme mit einer kleineren Luftzahl· (A. = o,8 - 1,1) als die Hauptbrennerflamme (A. = 1,1 - 1,3) betrieben wird.It has already been suggested that the dust flow / dust weight ratio for the dust ignition flame is smaller (0.5-1.0) than that of the main burner flame (1.5-2.0). It is also proposed that the dust ignition flame be operated with a smaller air ratio (A. = 0.8-1.1) than the main burner flame (A. = 1.1-1.3).

Wie die Praxis gezeigt hat, kann mit kleineren Werten das Verfahren zum Zünden einer Kohlenstaub-Rundbrennerflammeäurchgeführt werden.As practice has shown, the method for igniting a pulverized coal circular burner flame can be carried out with smaller values will.

Die vorliegende Erfindung hat sich daher die Aufgabe gestellt, das Verfahren auf diese Bereiche auszudehnen.The present invention has therefore set itself the task of extending the method to these areas.

Es wird daher ein VerfahrenIt therefore becomes a process

vorgeschlagen, welches dadurch gekennzeichnet ist, daß daß Staubluft-Staubgewichtsverhältnis für die Staubzündflamme 0,2 - o,5 beträgt, wobei das Staubluft-Staubgewicht sverhältnis für die Hauptbrennerflamme 1,5 - 2,ο
beträgt.proposed, which is characterized in that the dust air / dust weight ratio for the dust ignition flame is 0.2-0.5, the dust air / dust weight ratio for the main burner flame 1.5-2, ο
amounts to.

Ferner sieht das Verfahren vor, daß die Staubzündflamme mit einer Luftzahl von Λ = ο,4 - ο,8 betrieben wird und den für die vollständige Verbrennung erforderlichen zusätzlichen Luftstrom aus der Leckluft des Hauptbrenners bezieht.The method also provides that the dust ignition flame is operated with an air ratio of Λ = ο, 4 - ο, 8 and the additional air flow required for complete combustion from the main burner leakage air relates.
