Description
Gegenstand des Hauptpatents ist eine Einrichtung zur Erzeugung brennbarer Gase durch Vergasen eines feinverteilten, vorzugsweise festen Brennstoffes in der Schwebe mit Sauerstoff und gegebenenfalls Wasserdampf, mit einer gekühlten zentralen Metalldüse zum Einleiten des Brennstoff-Sauerstoff-Gemisches und einer die zentrale Düse umgebenden ringförmigen gekühlten Metalldüse zum Einblasen eines die aus feuerfestem keramischem Material bestehenden Wände des Reaktionsraumes schleierartig bedeckenden Schutzgases in den Reaktionsraum.The subject of the main patent is a device for the production of combustible Gases by gasifying a finely divided, preferably solid fuel in the Float with oxygen and possibly water vapor, with a chilled central Metal nozzle for introducing the fuel-oxygen mixture and a central one Nozzle surrounding ring-shaped cooled metal nozzle for blowing in one of the refractories ceramic material existing walls of the reaction chamber covering like a veil Protective gas into the reaction chamber.
Bei der Ausführungsform der Düse gemäß dem Hauptpatent wird die die zentrale Düse für das Brennstoff-Sauerstoff-Gemisch umgebende, ringförmige Düse für das den Schleier bildende gasförmige Medium sowohl an ihrer inneren als auch an ihrer äußeren Fläche von besonderen Kühlräumen begrenzt, die nur zur Kühlung der Ringdüse dienen und bezüglich, des Kühlmittels unabhängig voneinander sind.In the embodiment of the nozzle according to the main patent is the central nozzle for the annular nozzle surrounding the fuel-oxygen mixture for the gaseous medium forming the veil, both at its interior and at limited on their outer surface by special cold rooms that are only used for cooling serve the ring nozzle and are independent of each other with respect to the coolant.
Es hat sich überraschenderweise gezeigt, daß man eine ausreichende Kühlung der Ringdüse für das sogenannte Schleiergas auch dann noch erzielen kann, wenn man als äußere Begrenzungsfläche der Ringdüse nach wie vor einen besonderen, nur der Ringdüse zugeordneten Kühlraum vorsieht, die innere Begrenzungsfläche der Ringdüse jedoch durch den ohnehin gekühlten Mantel der zentralen Düse für das Brennstoff-Sauerstoff-Gemisch bilden läßt. Der Vorteil der erfindungsgemäßen Ausführungsform liegt in der einfacheren Konstruktion der die Ringdüse bildenden Bauelemente und in dem Wegfall eines der bisher notwendigen zwei Kühlmittelumläufe für die Ringdüse.It has been shown, surprisingly, that you can get a sufficient Can still achieve cooling of the ring nozzle for the so-called curtain gas, if you still have a special, only provides the cooling space associated with the ring nozzle, the inner boundary surface of the Ring nozzle, however, through the already cooled jacket of the central nozzle for the fuel-oxygen mixture can form. The advantage of the embodiment according to the invention is that it is simpler Construction of the components forming the ring nozzle and in the absence of one of the previously necessary two coolant circulations for the ring nozzle.
In der Abbildung ist eine Ausführungsform der Erfindung dargestellt.In the figure, an embodiment of the invention is shown.
Der Vergasungsraum r, dessen Wände von feuerfestem Material 2 gebildet werden, erweitert sich konisch in Strömungsrichtung der Reaktionsmedien.The gasification chamber r, the walls of which are made of refractory material 2 expands conically in the direction of flow of the reaction media.
Das Brennstoff-Sauerstoff-Gemisch wird zentral durch beispielsweise drei wassergekühlte Düsenrohre 3 in den Reaktionsraum eingeblasen. Das Kühlmittel für die zentrale Düse tritt durch Leitung 13 ein, wird durch ein Rohr bis in die Näh;. des in den Reaktionsraum hineinragenden Endes der Düse geführt und verläßt die Düse durch Leitung i4.The fuel-oxygen mixture is blown centrally through, for example, three water-cooled nozzle tubes 3 into the reaction space. The coolant for the central nozzle enters through line 13 , is through a pipe up to the sewing. of the end of the nozzle protruding into the reaction chamber and leaves the nozzle through line i4.
Die zentrale Düse 3 ist von einer ringförmigen Düse 4 umgeben, die durch einen Ringkanal 12 mit einem Zuführungsrohr z z für beispielsweise überhitzten Wasserdampf verbunden ist. Die äußere Begrenzungsfläche der Ringdüse 4 bildet ein in Form eines Doppelmantels ausgebildeter Kühlraum 6. Durch diesen Kühlraum läuft ein Kühlmittel, beispielsweise Wasser, unter erhöhtem Druck um. Da: Kühlmittel wird bei 7 zugeführt und fließt bei d wieder ab.The central nozzle 3 is surrounded by an annular nozzle 4, the through an annular channel 12 with a feed pipe z z for overheated, for example Water vapor is connected. The outer boundary surface of the ring nozzle 4 forms a Cooling space 6 designed in the form of a double jacket. Runs through this cooling space a coolant, for example water, under increased pressure. Since: coolant is at 7 and flows out again at d.
Die innere Begrenzungsfläche der Ringdüse wird von dem gekühlten Rohr 3 der zentralen Düse für das Brennstoff-Sauerstoff-Gemisch gebildet. Auf diese Weise wird das bisher notwendige zweite Kühlsystem für die innere Begrenzungsfläche der Ringdüse vermieden und der Gesamtaufbau des Düsenkopfes vereinfacht.The inner boundary surface of the ring nozzle is made up of the cooled pipe 3 formed the central nozzle for the fuel-oxygen mixture. In this way becomes the previously necessary second cooling system for the inner surface of the Ring nozzle avoided and the overall structure of the nozzle head simplified.
