Description

Steilrohrkessel. Gegenstand der Erfindung ist eine Verbesserung und weitere Ausgestaltung des Steilrohrkessels gemäß Patent 425171, bei dem zur Erzielung eines möglichst gleichmäßigen Wasserumlaufs das Rohrbündel durch eine Mitteltrommel in ein oberes und unteres Rohrbündel geteilt ist und der- Zug der Heizgase vom oberen Rohrbündel zum unteren Rohrbündel erfolgt, während der Wasserabfall durch unbeheizte Fallrohre vor sich geht. Die Verbesserung und weitere Ausgestaltung besteht darin, daß bei einem Kessel dieser Art mit drei oder mehr senkrecht übereinander angeordneten Trommeln die Verbindungsröhre von Trommel zu Trommel, und zwar von unten nach oben immer stärker, an Zahl jedoch immer geringer werden.Steep tube boiler. The invention is an improvement and further embodiment of the steep tube boiler according to patent 425171, in which to achieve the tube bundle through a central drum to ensure that the water circulates as evenly as possible is divided into an upper and lower tube bundle and the train of the heating gases from the upper Tube bundle to the lower tube bundle takes place while the water drops through unheated Downspouts going on. The improvement and further development consists in that in a boiler of this type with three or more arranged vertically one above the other Drum the connecting tube from drum to drum, from bottom to top getting stronger, but decreasing in number.

Auf der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt.The subject of the invention is shown in one embodiment in the drawing shown.

Das Kesselsystem besteht aus eileer Untertrommel 12, einer Mitteltrommel 13, einer Obertrommel 14, einer Speisetrommel 15 und einer über dieser liegenden Dampftrommel 16. Unteitrommel12 und Mitteltrommel 13 sind dui ch enge Rohre 1 7 miteinander verbunden. Die Verbindung zwischen der Obertrommel 14 und der Mitteltrommel 13 wird durch Rohre 18 von größerem Durchmesser vermittelt.The boiler system consists of eileer lower drum 12, a center drum 13, an upper drum 14, a feed drum 15 and a 16 lying above this steam drum and means Unteitrommel12 drum 13 dui ch narrow pipes 1 7 are connected to each other. The connection between the upper drum 14 and the central drum 13 is provided by tubes 18 of larger diameter.

Von der Obertrommel 14 gehen weite abfallende Rohre i9 zur Speisetrommel 15 und weite ansteigende Rohre 20 zur Dampftrommel 16, welche ihrerseits durch weite senkrechte Rohre 21 mit der Speisetrommel 15 in Verbindung steht. Von der Speisetrommel 15 gehen zwei weite, in die Untertrommel 12 mündende Rohre 22 aus, welche außerhalb des Heizraumes liegen.From the upper drum 14, wide sloping pipes 19 go to the feed drum 15 and wide rising pipes 20 to the steam drum 16, which in turn by wide vertical tubes 21 with the feed drum 15 is in communication. From the feed drum 15 two wide tubes 22 which open into the lower drum 12 and which are outside of the boiler room.

Die Heizgase streichen in der Pfeilrichtung a senkrecht nach oben und dann zwischen der Mitteltrommel 13 und der Obertrommel 14 hindurch, um nunmehr im Gegenstrom das untere Rohrbündel 17 schlangenförmig zu durchstreichen und durch den Economiser zum Kamin zu entweichen. Ein geringer Teil der den Feuerraum verlassenden Heizgase gelangt unmittelbar in der- Pfeilrichtung b zum Economiser. Diese Heizgasmenge kann durch einen Schieber 23 geregelt werden.The heating gases sweep vertically upwards in the direction of the arrow a and then between the central drum 13 and the upper drum 14 through to now in countercurrent to cross the lower tube bundle 17 serpentine and through the economiser to escape to the chimney. A small part of those leaving the combustion chamber Heating gases directly in the direction of arrow b to the economiser. This amount of heating gas can be regulated by a slide 23.

Sämtliche Trommeln sind vom Heizraum abgeschaltet bzw. isoliert, die Rohrbündel werden von den Heizgasen von oben nach unten durchstrichen, und die Obertrommel und Untertrommel miteinander verbindenden Fallrohre liegen außerhalb des Heizraumes. Die Anordnung der einzelnen Trommeln senkrecht übereinander und ihre Verbindung durch gerade Rohrbündel sind besonders vorteilhaft, da der Auftrieb des Dampf- und Wassergemisches in senkrechter Richtung erfolgt und infolgedessen keinen Widerstand an schrägen Steigrohren findet.All drums are switched off or isolated from the boiler room Tube bundles are crossed by the heating gases from top to bottom, and the upper drum and downpipes connecting the lower drum are outside the boiler room. The arrangement of the individual drums vertically one above the other and their connection through straight tube bundles are particularly advantageous as the buoyancy of the steam and Mixing water takes place in the vertical direction and consequently no resistance found on inclined risers.

Da die unteren Rohre 17 dünner und zahlreicher sind als die oberen Rohre 18, nimmt die Heizfläche von unten nach oben ab, während die Temperatur der Heizgase von unten nach oben zunimmt. Dadurch ist eine Anpassung der Heizgastemperatur an die jeweilige Heizfläche und umgekehrt gegeben. Überhaupt sind Belastungstemperatur, Rohrzahl, Rohrlänge und Rohrquerschnitte gegeneinander abgestimmt zwecks Erzeugung einer von der Untertrommel bis zur Obertrommel ständig wachsenden Geschwindigkeit des Dampf- und Wassergemisches. Diesem Zweck ordnet sich die Ausbildung der einzelnen Rohrbündel unter, welche im Bedarfsfalle auch eine andere sein kann wie die in dien Zeichnungen dargestellte.Since the lower tubes 17 are thinner and more numerous than the upper tubes 18, the heating surface decreases from bottom to top, while the temperature of the heating gases increases from bottom to top. This enables the heating gas temperature to be adapted to the respective heating surface and vice versa. In general, the load temperature, number of tubes, tube length and tube cross-sections are coordinated with one another in order to generate a constantly increasing speed of the steam and water mixture from the lower drum to the upper drum. The formation of the individual tube bundles is subordinate to this purpose, which, if necessary, can also be different from the one shown in the drawings.
