Description
Schwenkbare Brennerdüse für Drehöfen Das Kohlenstaubrohr mit der Brennerdüse bei den Drehöfen zum Brennen von Zemen' liet bei den jetzigen Ausführungen meist in' der Achse des Ofenrohres. Es ist entweder fest eingebaut, kann also in seiner Lage nicht mehr geändert werden, oder es besitzt vor dem Ofenkopf ein Gelenk, das gestattet, daß die Düse in einem Winkel zur Ofenachse eingestellt werden kann. Eine «eitere Ausführungsart ist die Schiebedüse, die in axialer Richtung verschoben werden kann.Swiveling burner nozzle for rotary kilns The coal dust pipe with the burner nozzle In the case of the rotary kilns for firing cement, it is mostly the current versions in 'the axis of the stovepipe. It is either permanently installed, so it can be in his Position cannot be changed, or it has a joint in front of the furnace head that allows the nozzle to be adjusted at an angle to the furnace axis. One Another embodiment is the sliding nozzle, which can be moved in the axial direction can.
Gegenstand der vorliegenden Erfindung ist nun eine Brennerdüse, die durch Schwenken des Kohlenstaubrohres parallel zu sich selbst die Flamme dem Brenngut im Ofenrohr nähert und auch wieder entfernt, wobei die Flamme immer parallel zur Achse des Ofenrohres bleibt und in ihrer ganzen Länge die Oberfläche des sich umwälzenden Ofeninhalts bestreicht.The present invention is now a burner nozzle which by swiveling the coal dust pipe parallel to itself, the flame is attached to the material to be burned approaches in the furnace tube and also removed again, the flame always parallel to the The axis of the stovepipe remains and the surface of the rotating one in its entire length remains The contents of the oven.
Diese Ausführung hat gegenüber den bekannten und bereits aufgezählten den Vorteil, daß sie eine weit bessere Wärmeausnutzung gestattet, da die Entfernung der Wärmequelle vom Wärme aufnehmenden Körper a'uf das praktisch mögliche Kleinstmaß eingestellt «-erden kann, während gleichzeitig die Ausstrahlung an das freie Ofenfutter durch Vergrößerung des Abstandes verkleinert wird. Da diese Einstellung über die ganze Länge der Flamme wirksam ist und diese in ihrer Richtung stets parallel zur Oberfläche der Schicht des Brenngutes bleibt, ist die Wärmeübertragung über eine große Fläche verteilt, zum Unterschied zur schräg einstellbaren Düse, die die Flamme auf eine verhältnismäßig kleine Fläche aufstrahlen läßt.This version has compared to the known and already enumerated the advantage that it allows a far better utilization of heat, since the distance the heat source from the heat-absorbing body to the smallest possible practically possible can be set «-ground, while at the same time the radiation to the free furnace lining is decreased by increasing the distance. Since this setting is via the entire length of the flame is effective and this direction is always parallel to The surface of the layer of the material to be fired remains, the heat transfer is via a large area, in contrast to the inclined adjustable nozzle, which the flame can radiate onto a relatively small area.
Die Zeichnung stellt ein Ausführungsbeispiel dar.The drawing shows an exemplary embodiment.
Abb. i ist eine Ansicht des Ofens mit eingebautem Brenner in der Längsrichtung, während Abb. 2 ein Schnitt durch die Achse A-B, senkrecht zur Gutschicht, ist.Fig.i is a longitudinal view of the furnace with built-in burner, while Fig. 2 is a section through the axis A-B, perpendicular to the material layer.
a ist das Ofenrohr, das in den Ofenkopf b mündet und in den das Brenngute ausgetragen wird. Das Kohlenstaubrohr d hat eine S-fö rmige Krümmung. Die Achsen des geraden Rohrstückes vor der Krümmung ist die Schwenkachse für das Rohrstück mit der Düse. Die Lage der Achse e ist so angeordnet, daß der Schwenkbogen f der Düse in die Richtung der Achse A-B fällt, die Bewegungsrichtung somit senkrecht zur Gutoberfläche ist. a is the furnace tube that opens into the furnace head b and into which the material to be fired is discharged. The pulverized coal pipe d has an S-shaped curvature. The axis of the straight pipe section in front of the curve is the pivot axis for the pipe section with the nozzle. The position of the axis e is arranged so that the swivel arc f of the nozzle falls in the direction of the axis AB, the direction of movement is thus perpendicular to the surface of the product.
