Zusatz zum Patente JU 80277 vom 12. Juni 1894.Addendum to patent JU 80277 from June 12, 1894.
Patentirt im Deutschen Reiche vom 31. Juli 1894 ab. Längste Dauer: 11. Juni 1909.Patented in the German Empire on July 31, 1894. Longest duration: June 11, 1909.
Die durch das Patent Nr. 80277 geschützte Kohlenstaubfeuerung ist dahin abgeändert, dafs dem Luftstrom, der den Kohlenstaub nach dem Verbrennungsraum trägt, neben der fortschreitenden auch eine drehende Bewegung um seine Achse gegeben wird, welche der Erhaltung der gleichmäfsigen Vertheilung des Staubes in den Luftstrom förderlich ist. . Hat man die Bewegung der Lufttheilchen schon in eine schraubenförmige verwandelt, bevor sie während des Vorbeiganges an dem Ablenkungskörper mit dem Kohlenstaub beladen werden, so wird dadurch bereits die gleichmäfsige Einmischung des letzteren in die Luft begünstigt, besonders, wenn bei rotireridem Ablenkungskörper der Drehungssinn desselben demjenigen des Luftstromes entgegengesetzt ist. Die Drehung des Luftstromes wird durch Schraubenflächen hervorgebracht, welche von der Wand des Luftrohres ausgehen und sich am besten in der Mitte nicht vereinigen, sondern einen inneren Raum freilassen.The pulverized coal furnace protected by patent no. 80277 has been modified so that the air flow that carries the coal dust to the combustion chamber, next to the advancing one a rotating movement about its axis is also given, which helps to maintain the uniform distribution of the Dust in the air flow is beneficial. . If the movement of the air particles is already in transformed into a helical shape before they are loaded with the coal dust while passing the deflector, in this way the even mixing of the latter in the air is already favored, especially when, in the case of a rotating deflector body, its sense of rotation corresponds to that of the body of the air flow is opposite. The rotation of the air flow is made by helical surfaces produced, which emanate from the wall of the air pipe and are best in do not unite the middle, but leave an inner space free.
In dem in der Zeichnung dargestellten Ausführungsbeispiel sind die Schraubenflächen s in drei Gruppen angeordnet, von denen die erste s1 sich vor dem Ablenkungskörper c, die zweite s'2 hinter demselben und die dritte s3 vor der Ausmündung des Luftrohres α in den Verbrennungsraum befindet.In the embodiment shown in the drawing, the helical surfaces s are arranged in three groups, of which the first s 1 is located in front of the deflection body c, the second s' 2 behind it and the third s 3 in front of the opening of the air pipe α into the combustion chamber .
