  KohlenstaubfeuerungsanlagefürWasserrohrkessel. 



   Den Gegenstand der Erfindung bildet eine Kohlenstaubfeuerungsanlage für Wasserrohrkes, el derjenigen bekannten Art, bei welcher ein in der Spitze eines Dreiecks angeordneter senkrecht zur Dreieckfläche verlaufender Oberkessel durch Wasserröhren mit zum Oberkessel parallelen in den unteren beiden Eckpunkten des Dreiecks befindlichen Wassersammlern verbunden ist und besteht darin, dass in die

   Durch den haubenartigen Einbau wird die Flamme auch   breitgedrüekt   und dadurch die weitere Wirkung erzielt, dass die Flamme gleichmässig verteilt und umso sicherer auch den seitlich gelegenen Wasserröhren zugeführt wird. 



   Die Zeichnung, welche ein Beispiel der Anlage zeigt, bringt in Fig. 1 einen senkrechten Schnitt der Anlage zur Darstellung und in Fig. 2 eine Vorderansicht bei teilweisem Schnitt nach der Linie x-x der Fig. 1. 



   Ein in der Spitze des Dreiecks angeordneter   Oberkessel j !   ist durch Wasserrohre   2   mit parallelen in den unteren beiden Eckpunkten des Dreiecks befindlichen Wasseisammlern 3 verbunden. Der Brennstoff tritt durch den Brenner 4 ein und wird gegen eine Haube 5 gerichtet. die eine Umkehrung und ein Breitdrücken der Flamme bewirkt. 



   Es ist klar, dass durch die unmittelbare Beaufschlagung ein grösserer Heizeffekt erzielt werden   kann.   als wenn das in den Wasserrohren befindliche Wasser lediglich durch Strahlung der Flamme   erwärmt

  Coal dust firing system for water tube boilers.



   The subject matter of the invention is a pulverized coal firing system for water tube boilers, el of the known type in which an upper boiler arranged at the tip of a triangle and running perpendicular to the triangular surface is connected by water tubes with water collectors parallel to the upper boiler located in the lower two corners of the triangle and consists that in the
 EMI1.1
 



   Due to the hood-like installation, the flame is also spread out and the additional effect achieved is that the flame is evenly distributed and is all the more safely fed to the water pipes on the side.



   The drawing, which shows an example of the system, shows a vertical section of the system in FIG. 1 and a front view with partial section along the line x-x in FIG. 1 in FIG. 2.



   An upper boiler arranged at the tip of the triangle j! is connected by water pipes 2 with parallel water collectors 3 located in the lower two corners of the triangle. The fuel enters through the burner 4 and is directed against a hood 5. which causes a reversal and a spreading of the flame.



   It is clear that a greater heating effect can be achieved through the direct application. as if the water in the water pipes is only heated by radiation from the flame

EMI1.3 Boiler are connected, characterized in that a hood-like installation (5) is arranged in the furnace of such a boiler system opposite the fuel entry point, which causes a reversal of the flame in a manner known per se in order to achieve the relatively long zone of maximum heating when burning coal dust to use the heating of the water pipes appropriately.
