Description

  

   <Desc/Clms Page number 1> 
 



  Kohlenstaubfeuerung. 



   Bei Kohlenstaubfeuerungen muss der Kohlenstaub aus dem Behälter möglichst fein und gleichmässig verteilt in die Mischkammer, in der er mit dem Luftstrom vereinigt wird, eingeführt werden. 



  Für diesen Zweck dient nach der Erfindung die in der Zeichnung in einem Ausführungsbeispiel dargestellte Vorrichtung. 



   Unter dem   Kohlenstaubbehälter   a ist ein Sieb b fest eingespannt, das den Boden des Behälters bildet. Dieses Sieb ist mit einer Klopfvorrichtung versehen, die in dem gezeichneten Beispiel aus einem unter dem Siebe angeordneten federnden Hammer c besteht, der durch einen umlaufenden Hubfinger d abwechselnd gespannt und losgelassen wird, so dass er von unten gegen das Sieb schlägt. Die Erschütterungen befördern einerseits die Kohlenstaubteilehen durch das Sieb hindurch und verhüten anderseits das Zusetzen der Siebmaschinen. Eine Regelung der aus dem Behälter zu entnehmenden Kohlenstaubmenge kann durch Veränderung der Umlaufzahl des Hubfingers geschehen.

   Schwingende Siebe, die für den gleichen Zweck angewandt worden   sind,. erfüllen   ihn nur unzureichend, da die Maschen des Siebes sich leicht zusetzen und eine Regelung der   zuzuführenden   Menge nicht oder nur in   ungenügender   Weise   möglich   ist.

  Pulverized coal firing.



   In the case of pulverized coal firing, the pulverized coal must be introduced from the container as finely and evenly as possible into the mixing chamber in which it is combined with the air flow.



  For this purpose, the device shown in the drawing in an exemplary embodiment is used according to the invention.



   A sieve b is firmly clamped under the coal dust container a and forms the bottom of the container. This sieve is provided with a tapping device which, in the example shown, consists of a resilient hammer c arranged under the sieve, which is alternately tensioned and released by a rotating lifting finger d so that it strikes the sieve from below. On the one hand, the vibrations convey the coal dust particles through the sieve and, on the other hand, prevent the sieving machines from clogging. The amount of coal dust to be removed from the container can be regulated by changing the number of revolutions of the lifting finger.

   Vibrating sieves that have been applied for the same purpose. meet it only inadequately, since the meshes of the sieve easily clog and control of the amount to be added is not possible, or only inadequately.
