Description
Senkrecht stehender Dampferzeuger mit ringförmigem Wasserraum und innerer Beheizung. Es ist bekannt, bei einem ringförmigen Kessel die Heizgase, nachdem sie den inneren Mantel des Kessels bestrichen haben, an dem äußeren Mantel entlang zu führen, doch geschieht dies, um die Heizfläche des Kessels zu vergrößern. Es ist auch bekannt, bei einem Steilrohrkessel die untere Seite der Unterkessel während des Anheizens des Kessels zu beheizen, damit übermäßige Wärmespannungen, die- bei fehlender Beheizung der Unterkessel in deren Wandungen .eintreten würden, zu verhindern. Demgegeniüber soll nach der Erfindung bei einem senkrecht stehenden Kessel mit ringförmigem Wasserrauen, der lediglich eine innere Beheizung hat, der Außenmantel von einem kleinen Teilstrom der Heizgase bestrichen werden, der so bemessen ist, daß ein Temperaturgleichgewicht in dem Außenmantel herrscht. Dieses Gleichgewicht, das dazu dienen soll, Wärmespannungen in dem äußeren Mantel zu vermeiden, soll nicht nur beim Anheizen, sondern auch zu jeder Betriebszeit aufrechterhalten werden.Vertical steam generator with a ring-shaped water space and internal heating. It is known, in an annular boiler, the heating gases after they painted the inner shell of the kettle, along the outer shell to lead, but this is done in order to increase the heating surface of the boiler. It is also known, in a steep tube boiler, the lower side of the lower boiler during the heating of the boiler to heat, thus excessive thermal stresses that- at lack of heating of the lower boiler in the walls of which .ein would prevent. In contrast, according to the invention in a vertical boiler with an annular Rough water, which only has internal heating, the outer jacket of one small partial flow of the heating gases are coated, which is dimensioned so that a temperature equilibrium prevails in the outer jacket. This equilibrium, which should serve to relieve thermal stress Avoid being in the outer jacket is intended not only when heating up, but also too be maintained at any operating time.
In Abb. r der Zeichnung ist eine Ausführungsform des Kessels im Höhenschnitt und in Abb. z in teilweisem Horizontalschnitt dargestellt. Der Kessel hat einen ringförmigen Wasserraum a. An dem oberen Ende des Kessels ist ein gleichachsiger Innenkessel b angeordnet, der den Brennraum nach oben bis, auf einen ringförmigen Abzugskanal c abschließt.In Fig. R of the drawing is an embodiment of the boiler in vertical section and shown in Fig. z in partial horizontal section. The kettle has one annular water space a. At the top of the Kessels is a coaxial inner boiler b arranged, the combustion chamber up to, on one ring-shaped exhaust channel c closes.
Als Beheizung des Kessels ist eine Kohlenstaubfeuerung angenommen. Das Kohlenstaub-Luft-Gemisch strömt durch das Rohr d in den Brennraum e. Die Heizgase ziehen durch den ringförmigen Kanal c in die Höhe und ziehen dann durch den Kanal/ weiter, um Wärme an den überhitzer und den Eoonomis.er abzugeben.A pulverized coal furnace is assumed to be used to heat the boiler. The coal dust-air mixture flows through the pipe d into the combustion chamber e. The heating gases pull up through the annular channel c and then continue through the channel / to give off heat to the superheater and the eoonomis.er.
Ein kleiner Teilstrom der Heizgase zweigt jedoch in der Kammer g von den Heizgasen ab und strömt an dem ,äußeren Mantel i des Kessels entlang nach unten, um durch das Rohr k nach dem Fuchs zu gelangen. Dieser Teilstrom der Heizgase soll so bemessen sein, daß ein Temperaturgleichgewicht in dem äußeren Kes.sehnantel i besteht. Dies wird erreicht, wenn die Temperatur der Kesselwand gleich der Temperatur des. von ihr eingeschlossenen Wassers ist.However, a small partial flow of the heating gases branches off in chamber g the heating gases and flows down along the outer jacket i of the boiler, to get through the pipe k to the fox. This partial flow of the heating gases should be dimensioned so that a temperature equilibrium in the outer Kes.sehnantel i consists. This is achieved when the temperature of the boiler wall equals the temperature of the water enclosed by it.
In denn Rohr h ist eine Drosselklappe angeordnet, mit denen Hilfe die Stärke des Teilstromes ,geregelt werden kann.In the tube h there is a throttle valve with which help the strength of the partial flow can be regulated.
