Description

Steilrohrkessel Die Erfindung bezieht sich auf einen Steilrohrkessel mit zwischen den Ober- und Untertrommeln liegender Brennkammer, in der eine senkrecht von unten eingeblasene Flamme U-förmig umkehrt. Gemäß Patent 518 517 ist für diese Steilrohrkessel vorgeschlagen, die Brenner bei einseitigem Abzug der Feuergase in der Mitte der den weiteren Kesselzügen gegenüberliegenden Brennkammerhälfte anzuordnen.Vertical tube boiler The invention relates to a vertical tube boiler with a combustion chamber located between the top and bottom drums in which a flame that is blown in vertically from below is reversed in a U-shape. According to patent 518 517, it is proposed for these steep-tube boilers to arrange the burners in the middle of the combustion chamber half opposite the other boiler passes when the flue gases are drawn off on one side.

Bei einseitigem Abzug der Feuergase fällt nun die Asche in der Hauptsache auf nur einer Seite der Brennkammer nieder, und zwar zwischen den Brennern und den weiteren Kesselzügen. Um bei diesem starken Aschenanfall auf nur einen Teil der Brennkammer ein Zusetzen der Aschentrichter zu verhüten und um ferner wegen der Rückstrahlung der umkehrenden Kohlenstaubflamme auf die Brenner diese gut zu kühlen,, sind erfindungsgemäß zwischen den in einer Reihe nebeneinanderstehend angeordneten Brennern jeweils zwei in einer Ebene übereinanderliegende Kühlrohre hindurchgeführt, die in dein zwischen den Brennern und der Untertrommel liegenden Brennkammerteil aus ihrer Ebene derart herausgebogen sind, daß sie einen Granulierrost mit gegeneinander versetzt angeordneten Rohren bilden.If the fire gases are drawn off on one side, the ashes will mostly fall on only one side of the combustion chamber, between the burners and the further boiler trains. In order to reduce to only part of the ashes Combustion chamber to prevent clogging of the ash funnel and also because of the Reflection of the reversing pulverized coal flame on the burner to cool them well, are according to the invention between those arranged in a row next to each other Two cooling tubes, one on top of the other, are passed through the burners, the part of the combustion chamber located between the burners and the lower drum are bent out of their plane in such a way that they have a granulating grate with one another form staggered tubes.

An sich ist die Anordnung eines Granulierrostes bei Steilrohrkesseln mit einer Stulpflamme, ebenso wie das Kühlen der Brenner durch Rohre bekannt. Ebenfalls ist es nicht mehr neu,. Wandkühlrohre an der Stelle, wo die Brenner liegen, seitlich auszubiegen. Die Erfindung besteht demgegenüber in der besonderen Anordnung und Abbiegung von jeweils zwei übereinanderliegenden Kühlrohren. Dadurch, daß die zwischen. den in einer Reihe nebeneinander angeordneten Brennern hindurchgeführten Kühlrohre nach ihrem Durchgang zwischen den einzelnen Brennern aus ihrer Ebene herausgebogen sind, werden auch die sonst von den da.rüberliegenden Rohren verdeckten Rohre zu einer wirksamen Granulierrostfläche.In itself, the arrangement of a granulating grate is in steep tube boilers with a cover flame, as well as cooling the burner through pipes. Likewise it is no longer new. Wall cooling pipes on the side at the point where the burners are located to bend out. In contrast, the invention consists in the special arrangement and Bending of two cooling tubes, one on top of the other. Because the between. the cooling tubes passed through the burners arranged in a row next to one another after their passage between the individual burners bent out of their plane are, the pipes otherwise covered by the pipes over there will also be closed an effective granulating grate surface.

Auf der Zeichnung ist die Erfindung beispielsweise dargestellt, und zwar zeigt Abb. i einen Längsschnitt durch einen Steilrohrkessel, Abb. 2 einen Grundriß dazu.In the drawing, the invention is shown, for example, and although Fig. i shows a longitudinal section through a steep tube boiler, Fig. 2 shows a plan to.

Es bezeichnen wie im Hauptpatent 1 und 2 die Ober- und die 'Untertrommel, 3 die Steigrohre, 4 die Brennkammer und 5 die Brenner des Kessels. Die einzelnen Brenner 5 haben nebeneinanderliegend einen gewissen Abstand voneinander, durch den die Brennerkühlrohre 14 und 15 hindurchgeführt sind. Diese Rohre 14 und 15 sind einerseits an die Untertrommel 2, andererseits an die Wasserkammer 16 angeschlossen, die durch die Steigrohre 3 mit der Obertrommel i in Verbindung steht.As in the main patent 1 and 2, it denotes the upper and lower drum, 3 the riser pipes, 4 the combustion chamber and 5 the boiler burners. The single ones Burner 5 adjacent to each other have a certain distance from each other, through the the burner cooling tubes 14 and 15 are passed through. These tubes 14 and 15 are connected on the one hand to the lower drum 2, on the other hand to the water chamber 16, which is connected to the upper drum i through the riser pipes 3.

Wie die Abb. i zeigt, liegen die Rohre 14 oberhalb der Rohre 15, jedoch sind die Rohre 15 zwischen den Brennern 5 und der Untertrommel 2 nach dem Durchgang durch die Brenner 5 bei 17 abgebogen, so daß sie, im Grundriß gesehen (Abb. 2), zwischen den Rohren 14 auf Lücke stehen. Dadurch wird mit den Brennerkühlrohren 14 und 15 gleichzeitig eine Vergrößerung des Granulierrostes für den bei einseitigem Gasabzug erhöhten Aschenanfall auf der Seite zwischen den Brennern 5 und der Untertrommel 2 erreicht.As Fig. I shows, the tubes 14 are above the tubes 15, however are the tubes 15 between the burners 5 and the lower drum 2 after the passage bent by the burner 5 at 17 so that, seen in plan (Fig. 2), stand between the tubes 14 on a gap. This will use the torch cooling tubes 14 and 15 at the same time an enlargement of the granulating grate for the one-sided Gas exhaust increased ash accumulation on the side between the burners 5 and the lower drum 2 reached.
