  Brenner für Kohlenstaubfeuerungen. 



   Bei Brennern für Kohlenstaubfeuerungen ist man nur schwer in der Lage, die Geschwindigkeit des in den Feuerraum eintretenden Staubes zu regeln und gelingt dies bloss durch Beigabe von mehr oder weniger Luft, was selbstverständlich nicht immer mit den Anforderungen der Feuerung in Einklang zu bringen ist. Um eine möglichst rasche und gründliche Verbrennung zu erzielen, ist es notwendig, den Brennstaub aus dem Brenner in die Kammer mit einer möglichst kleinen Geschwindigkeit eintreten zu lassen. 



   Im allgemeinen ist diese Geschwindigkeit von der Rückzündungsmöglichkeit abhängig, die bei gasreichen Kohlen natürlich weit grösser ist als bei minder gasreichen Brennstoffen. 



   Gegenstand der vorliegenden Erfindung ist es, eine Einrichtung zu schaffen, die es gestattet, unabhängig von der Luftzuführung die Geschwindigkeit des in die Kammer eintretenden Brennstaubes in weiten Grenzen zu regeln, ohne dass die Gefahr einer   Rückzündung   besteht. 



   Erfindungsgemäss wird dies dadurch erreicht, dass nächst oder an der Mündung des Brenners eine Prellplatte angebracht ist, die drehbar und feststellbar ist. Beim Auftreffen auf diese Platte wird ein Teil der Geschwindigkeit, die der Brennstoff besitzt, vernichtet. Dieser tritt daher in die Kammer nur mit einer Komponente seiner früheren Geschwindigkeit ein, die um so kleiner ist, je grösser der Winkel ist, den das freie Ende der Prellplatte. mit der Achse der Brenndüse einschliesst. 



   Der Gegenstand der Erfindung ist in der Zeichnung dargestellt und besteht aus der im vorliegenden 
 EMI1.1 
 gegeben, die Richtung der Kohlenstaubflamme zu lenken oder zu leiten, worin ein weiterer Vorteil der Einrichtung gelegen ist. 



   PATENT-ANSPRÜCHE :
1. Brenner für Kohlenstaubfeuerungen, dadurch gekennzeichnet, dass zwecks Vernichtung eines Teiles der Geschwindigkeit des Brennstoffes nächst oder an der Mündung des Brenners eine Prell-   platte (k)   vorhanden ist, die drehbar und feststellbar eingerichtet ist.

  Burners for pulverized coal firing.



   With burners for pulverized coal combustion it is difficult to regulate the speed of the dust entering the combustion chamber and this can only be achieved by adding more or less air, which of course cannot always be reconciled with the requirements of the combustion. In order to achieve the fastest and most thorough combustion possible, it is necessary to let the fuel dust from the burner enter the chamber at the lowest possible speed.



   In general, this speed depends on the possibility of reignition, which is of course much greater with gas-rich coals than with less gas-rich fuels.



   The object of the present invention is to create a device which allows the speed of the fuel dust entering the chamber to be regulated within wide limits, independently of the air supply, without the risk of re-ignition.



   According to the invention, this is achieved in that a baffle plate, which can be rotated and locked, is attached next to or at the mouth of the burner. When it hits this plate, part of the speed that the fuel possesses is destroyed. This therefore only enters the chamber with a component of its previous speed, which is the smaller, the greater the angle that the free end of the baffle plate. with the axis of the burner nozzle.



   The object of the invention is shown in the drawing and consists of the present
 EMI1.1
 given to direct or guide the direction of the pulverized coal flame, which is another advantage of the device.



   PATENT CLAIMS:
1. Burner for pulverized coal firing, characterized in that for the purpose of destroying part of the speed of the fuel next to or at the mouth of the burner there is a baffle plate (k) which is rotatable and lockable.
