Description
Beschickungsvorrichtung für Wanderroste Gegenstand der Erfindung ist eine Beschikkungsvorrichtung für Wanderroste. Es ist bekannt, Brennstoff vor der Beschickung des Rostes vorzutrocknen und die staubförmigen Bestandteile auszuscheiden, um sie einem besonderen Staubbrenner zuzuführen. Nach der Erfindung erfolgt die Abscheidung der staubförmigen Bestandteile des Brennstoffes in einer unmittelbar vor dem Aufgabetrichter des Rostes angeordneten Trockentrommel, und zwar dadurch, daß der die Trockentrommel durchziehende Heizgasstrom die staubförmigen Bestandteile des Brennstoffes aufnehmen soll und sie einem Windsichter zuführt, von dem aus sie einer Brenndüse zugeleitet werden. Dadurch soll der Vorteil erreicht werden, daß das Ausscheiden der staubförmigen Bestandteile und die Trocknung erfolgt, während der Brennstoff umgewälzt und in der Längsrichtung der Trockentrommel weiterbefördert wird. Die Einrichtung ist einfach, billig und wirtschaftlich, da die vorgewärmte Luft als Scheide-, Trocken- und -Fördermittel dient.Loading device for traveling grids is the subject of the invention a loading device for traveling grids. It is known to fuel before To pre-dry the loading of the grate and to separate out the dusty components, to feed them to a special dust burner. According to the invention, the Separation of the dusty components of the fuel in an immediate drying drum arranged in front of the feed hopper of the grate, namely, that the flow of heating gas passing through the drying drum removes the dust-like constituents of the fuel is to take up and it feeds an air classifier, from which it be fed to a burner nozzle. This is intended to achieve the advantage that the separation of the powdery components and the drying takes place while the fuel is circulated and conveyed further in the longitudinal direction of the drying drum will. The set up is simple, cheap and economical, since the preheated Air serves as a separating, drying and conveying means.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung teils in Ansicht, teils im Schnitt dargestellt.In the drawing, an embodiment of the invention is partly in View, partly shown in section.
Von, einer nicht gezeichneten Transportvorrichtung gelangt der nasse Brennstoff durch ein Fallrohr i in eine Trockentrommel 2, die beiderseits in feststehenden Abschlußhauben3 bzw. q. gelagert ist und mittels einer Antriebvorrichtung 5 bekannter Art in Drehung versetzt wird.The wet one comes from a transport device (not shown) Fuel through a downpipe i into a drying drum 2, both sides in stationary End hoods3 or q. is stored and by means of a drive device 5 known Kind is set in rotation.
Die Abschlußhauben3 und 4. sind an Rohre 6 bzw. p angeschlossen, durch die aus einem Lufterhitzer 8 mittels eines Ventilators 9 angesaugte heiße Luft durch die Trockentrommel geführt wird. Der Wtg des Brennstoffes und der heißen Luft ist durch entsprechend, Pfeile bezeichnet. Durch den Luftstrom mitgenommener staubförmiger * Brennstoff wird durch einen Abscheider io bekannter Art ausgeschieden, während der körnige und stücldge Teil durch die Haube q. in einen Aufgabetrichter i i und von dort auf den Wanderrost 12 gelangt, Zwo er durch einen Schichtregler 13 verteilt wird. Die dem Abscheider zugeführte Trockenluft wird durch ein Rohr 14 in den Aschenraum 15 geblasen. Der staubförmige Brennstoff sammelt sich unten im Abscheider meiner Entnahmevorrichtung 16, an die ein Rohr 17 beiderseits angeschlossen ist, an dessen einem Ende sein Gebläse 18 angeschlossen ist, und dessen anderes Ende in seine Düse i9 im Verbrennungsraum 2o mündet.The end caps 3 and 4 are connected to pipes 6 and p, respectively the hot air sucked in from an air heater 8 by means of a fan 9 through the drying drum is guided. The Wtg of the fuel and the hot air is indicated by corresponding arrows. Dust-like particles carried along by the air stream * Fuel is separated while by a separator of a known type the granular and lumpy part through the hood q. into a feed hopper i and i from there it reaches the traveling grate 12, where it is distributed by a stratification regulator 13 will. The dry air supplied to the separator is passed through a pipe 14 into the ash chamber 15 blown. The dusty fuel collects in the bottom of my separator Removal device 16, to which a pipe 17 is connected on both sides, to its one end of its fan 18 is connected, and the other end into its nozzle i9 opens in the combustion chamber 2o.
Anstatt dem Lufterhitzer 8 Luft zuzuführen, können auch aus einem nach dem Schorn, stein führenden Gaskanal zi heiße Abgase entnommen werden, die nach dem Durchgang durch die Trockentrommel wieder dem Schornsteinzugeführt werden.Instead of supplying air to the air heater 8, you can also use one After the chimney, the gas duct leading to the hot flue gases can be taken be fed back to the chimney after passing through the drying drum.
