Description

Die Erfindung betrifft ein Verteilerstück, welches die Aufgabe hat, ein Kohlenstaub-Luft-Gemisch möglichst gleichmäßig auf mehrere Brennerleitungen zu verteilen. _ Es ist bekannt, daß zum einwandfreien Arbeiten eines Brenners eine gleichmäßige Verteilung des Brennstoff-Luft-Gemisches gehört. Bei Kohlenstaub-Luft-Gemischen entstehen hierdurch besondere Schwierigkeiten. Man hat deshalb versucht, durch die verschiedenartigsten Einbauten und Maßnahmen, z. B. durch Klappen, Schieber, Prallplatten, Verteilerstücke und parallele sowie angeschärfte und der Verteilerform angepaßte Blechwände, verstellbare Gitter, außerdem durch wechselnde Geschwindigkeiten in Venturirohren und größeren Behältern, eine gleichmäßige Verteilung zu bewirken. Der gewünschte Erfolg wurde jedoch nur bei erheblichem Aufwand erreicht.The invention relates to a distributor piece, which has the task of a coal dust-air mixture as evenly as possible on several burner lines to distribute. _ It is known that for a burner to work properly, a even distribution of the fuel-air mixture. With coal dust-air mixtures This creates particular difficulties. One has therefore tried to go through the various fixtures and measures, e.g. B. by flaps, slides, baffle plates, Distributor pieces and parallel as well as sharpened and adapted to the distributor shape Sheet metal walls, adjustable grilles, also due to changing speeds in Venturi tubes and larger containers to effect an even distribution. However, the desired success was only achieved with considerable effort.

Der Erfindung liegt die Aufgabe, zugrunde, mit einfachsten Mitteln ein Verteilerstück zu schaffen, das mit einer betriebsmäßig zulässigen Abweichung von bis zu 5 °/o zwsichen den Einzelstaubmengen und dem Mittelwert ein Kohlenstaub-Luft-Gemisch auf mehrere Brennerleitungen verteilt. Ein physikalisches Gesetz besagt, daß bei Aufzweigung eines Flüssigkeits- oder Gasstromes die Verteilung nach der Größe der Widerstände erfolgt. Bei einem Kohlenstaub-Luft-Strom kommt lediglich noch die Forderung hinzu, daß das Gemisch vorher homogenisiert und unter gleichen Bedingungen den Einzelleitungen zugeführt wird. Zu diesem Zweck trägt eine lotrecht verlaufende Kohlenstaub-Luft-Gemisch-Steigleitung am Ende einer schlanken, pyramiden- oder kegelstumpfförmig oder mit zwei gegenüberliegenden, parallelen Wänden ausgebildeten, diffusorartigen Erweiterung einen zur lotrechten Achse symmetrisch gestalteten Abschluß, von welchem die mit möglichst weitgehender Symmetrie angeordneten, zu den Einzelbrennern führenden Rohre gleichen Strömungswiderstandes ausgehen.The invention is based on the object with the simplest means to create a manifold that has an operationally permissible deviation of up to 5 ° / o between the individual dust quantities and the mean value a coal dust-air mixture distributed over several burner lines. A physical law says that at Branch of a liquid or gas stream the distribution according to the size of the Resistance takes place. In the case of a coal dust-air flow, there is only one requirement added that the mixture was previously homogenized and the individual lines under the same conditions is fed. For this purpose, a vertical coal dust / air mixture riser pipe carries at the end of a slender, pyramidal or truncated cone or with two opposite, parallel walls formed, diffuser-like extension one to the perpendicular Axis symmetrically designed conclusion, from which the with as far as possible Symmetrically arranged pipes with the same flow resistance leading to the individual burners go out.

Besondere Vorteile des Verteilerstückes nach der Erfindung bestehen darin, daß mit einfachsten Mitteln ohne bewegliche und verschleißempfindliche Teile eine ausreichend gleichmäßige Verteilung des Kohlenstaub-Luft-Gemisches auf eine beliebige Anzahl von Brennerleitungen in betriebssicherer Weise erreicht wird.There are particular advantages of the distributor according to the invention that with the simplest means without moving and wear-sensitive parts a sufficiently even distribution of the coal dust-air mixture on a any number of burner lines is achieved in a reliable manner.

In der Zeichnung sind zwei. Ausführungsbeispiele des Erfindungsgegenstandes dargestellt. Abb. i zeigt einen flachen Diffusor im Längsschnitt Abb. 2 stellt denselben nach einer Drehung um 9o° im Schnitt dar; in Abb. 3 ist die Verteilerplatte eines kegelstumpfförmigen Diffusors veranschaulicht.In the drawing there are two. Embodiments of the subject matter of the invention shown. Fig. I shows a flat diffuser in longitudinal section, Fig. 2 shows the same after a rotation of 90 ° in section; in Fig. 3 the distributor plate is one frustoconical diffuser illustrated.

Die Zuführungsleitung i des Kohlenstaub-Luft-Gemisches trägt den Diffusor 2, der von der Verteilerplatte 3, mit den Brennerleitungen q. abgeschlossen wird.The supply line i of the coal dust-air mixture carries the diffuser 2, from the distributor plate 3, with the burner lines q. is completed.
