Description

Brennstaubfeuerung Bei dem Hauptpatent wird die Bodenöffnung des Verbrennungsraumes gegen den mit Wasser gefüllten Aschenraum durch eine kegelförmige Haube teilweise verdeckt, damit das Wasser nicht der unmittelbaren Einwirkung der Wärmestrahlen ausgesetzt ist und nicht zu stark erhitzt wird. Dieser gleichzeitig als Düse wirkenden Haube entströmt nach oben ein Luftschleier, der die miederfallenden Staubteilchen wieder nach oben treibt, dabei die heruntertropfende flüssige Schlacke plötzlich abkühlt und granuliert. Bei dieser Einrichtung kann es möglich sein, daß Teile der Schlacke an der Haube oder an dem Rand der Bodenöffnungen haftenbleiben und dadurch die Düse oder den ringförmigen Aschendurchlaß verstopfen. Die anhaftende Schlacke muß dann von außen abgestoßen werden, wodurch leicht Beschädigungen der Düse oder des Bodenrandes entstehen können.Combustion dust combustion In the main patent, the bottom opening of the combustion chamber is against the ash chamber filled with water by a conical hood partially concealed so that the water is not exposed to the direct action of heat rays exposed and not overheated. This also acts as a nozzle From the hood, an air curtain flows upwards, containing the dust particles falling on the corsetry floats up again, suddenly the dripping liquid slag cools and granulates. With this facility it may be possible that parts of the Slag stick to the hood or to the edge of the bottom openings and thereby clog the nozzle or the annular ash passage. The clinging slag must then be repelled from the outside, thereby easily damaging the nozzle or the edge of the floor can arise.

Zur Beseitigung dieses Nachteils wind gemäß vorliegender Erfindung die Einrichtung so getroffen, daß der die Bodenöffnung des Verbrennungsraumes abschließende Körper aus einer sich drehenden hohlen Trommel mit Luftzuführungslöchern im Mantel besteht, von welcher die auf sie tropfende Schlacke bei der Drehung nach unten abfällt und die mit ihren nach außen vorstehenden Rippen die am Rande der Bodenöffnung haftende Schlacke abkratzt.The present invention aims to eliminate this disadvantage the device made so that the bottom opening of the combustion chamber closes Body made from a rotating hollow drum with air inlet holes in the jacket consists of which the slag that drips onto it falls off as it rotates downwards and the one with its outwardly protruding ribs adhering to the edge of the bottom opening Scraping off slag.

In der beiliegenden Zeichnung ist die Anordnung ein Abb. i im Längsschnitt, in Abb. a im Querschnitt und in Abb. 3 im Grundriß dargestellt.In the accompanying drawing the arrangement is a Fig. I in longitudinal section, shown in Fig. a in cross section and in Fig. 3 in plan.

In der Bodenöffnung a des Verbrennungsraumes b ist die drehbare Trommel c angeordnet. Diese ruht fest auf der Achse d, die sich in den außerhalb des Aschenraumes e befestigten Lagern f dreht. Die drehende Bewegung der Achse d und der auf dhr sitzenden Trommel c erfolgt durch eine Transmission o. dgl. Die Achse ist an einer Seite in der Längsrichtung mit einer Durchbohrung versehen, die zur Aufnahme des in die Trommel hineinragenden Luftzuführungsrohres g dient. Durch dieses innerhalb der Trommel offene Rohr g wird vorgewärmte oder auch kalte Luft in die Trommel c geleitet und strömt aus den Schlitzen h. in der Trommelwandung nach oben in den Verbrennungsraum b. Nach unten, in den Aschenraume, kann keine Luft strömen, weil dieser allseitig geschlossen ist.The rotatable drum is located in the bottom opening a of the combustion chamber b c arranged. This rests firmly on the axis d, which is in the outside of the ash chamber e fixed bearings f rotates. The rotating movement of the axis d and that on dhr seated drum c takes place through a transmission o. The like. The axis is on one Side provided with a through hole in the longitudinal direction, which is used to accommodate the Air supply pipe g projecting into the drum is used. Through this within the drum open tube g is preheated or cold air into the drum c directed and flows out of the slots h. in the drum wall up into the Combustion chamber b. No one can go down into the ash-pan Air flow because it is closed on all sides.

Durch die aus der Trommel nach oben strömende Luft werden die niederfallenden Staubteilchen wieder nach oben in die Verbrennungszone getrieben, die abtropfende Schlacke plötzlich abgekühlt, dabei abgeschreckt und granuliert. Die auf die Trommel niederfallende Schlacke haftet infolge der Abschreckung nur lose daran und fällt beim Drehen der Trommel von selbst nach unten ab.Due to the air flowing up from the drum, the falling Dust particles are driven back up into the combustion zone, the dripping off Slag suddenly cooled, quenched and granulated. The one on the drum As a result of the deterrent, falling slag only loosely adheres to it and falls when the drum rotates downwards by itself.

Auf dem äußeren Umfang der Trommel sind vorstehende Rippen i vorgesehen, die den Zweck haben, die an dem Rand der Bodenöffnung a haftenbleibende Schlacke abzukratzen. Dadurch bleibt der zwischen der Trommel und dem Bodenrand offene Schlitz zum Durchlassen der niederfallenden Schlacke ständig frei und kann sich nicht verstopfen.Protruding ribs i are provided on the outer circumference of the drum, which have the purpose of removing the slag adhering to the edge of the bottom opening a scrape off. This leaves the slot open between the drum and the bottom edge to allow the falling slag to pass through and is always free and cannot become clogged.

Die neue Einrichtung bietet also unter Beibehaltung der Vorteile gemäß der Anordnung nach dem Hauptpatent noch den weiteren Vorteil, daß die Verstopfung der Luftzuführung und des Aschendurchlasses vermieden wird.The new facility thus offers while maintaining the advantages the arrangement according to the main patent has the further advantage that the clogging the air supply and the ash passage is avoided.

Außerdem wirkt die neue Anordnung günstig auf die breitere Verteilung des aus der sich drehenden Trommel nach oben strömenden Luftschleiers. Die Luft steigt nicht nur senkrecht in die Höhe, sondern bestreicht auch seitlich die untere innere Wandfläche des Verbrennungsraumes, so daß auch dort die darauf fallende Schlacke sich plötzlich abkühlt und nicht an der Wandung haftenbledbt.In addition, the new arrangement has a beneficial effect on the broader distribution of the air curtain flowing up from the rotating drum. The air not only rises vertically, but also brushes the lower one sideways inner wall surface of the combustion chamber, so that there too the slag falling on it suddenly cools down and does not stick to the wall.
