Description
Senkrecht stehender Dampferzeuger mit ringförmigem Wasserraum und Staubinnenfeuerung. Bei senkrecht stehenden Dampferzeugern mit ringförmigem Wasserraum und Staubinnenfeuerung ist es zweckmäßig, das Brennerrohr nicht in bekannter Weise von unten an den Brennerraum heranzuführen, sondern von oben. Dies hat zwei Vorteile: Erstens erfährt die Flamme durch ihren Auftrieb eine Umkehrung, wodurch der Weg, den die Staubteilchen im Brennraum zurückzulegen haben, verlängert wird. Der längere Weg erfordert eine längere Zeit, so daß die Verbrennung der Staubteilchen in einem kleineren Brennraum vor sich gehen kann, oder daß sie in dem größeren Brennraum eine gründlichere wird. Zweitens erfährt die Flamme bei ihrer Umkehr eine große Ausdehnung, so daß sie den Brennraum besser ausfüllt.Vertical steam generator with a ring-shaped water space and Internal dust firing. For vertical steam generators with a ring-shaped water space and internal dust firing, it is advisable not to use the burner tube in a known manner from below to the burner chamber, but from above. This has two advantages: First, the flame is reversed by its buoyancy, whereby the path which the dust particles have to cover in the combustion chamber is extended. The longer one Path requires a longer time, so that the combustion of dust particles in one smaller combustion chamber can go on, or that they are in the larger combustion chamber a more thorough one becomes. Second, when the flame is reversed, it experiences a great one Expansion so that it fills the combustion chamber better.
Damit das oberhalb der Flamme liegende Brennerrohr nicht selbst verbrennt, kann es in bekannter Weise durch einen Wassermantel, der sich in einem das Brennerrohr umschließenden zweiten Rohr befindet, gekühlt werden.So that the burner tube above the flame does not burn itself, it can be done in a known way through a water jacket, which is located in the burner tube surrounding second tube is located, be cooled.
Einfacher wird die Kühlung des Brennerrohres erreicht, wenn oberhalb des Brennraums ein dem Außenkessel ;gleichachsiger Innenkessel, angeordnet wird, durch dessen Mitte das Brennerrohr geführt wird.The cooling of the burner tube is more easily achieved if above of the combustion chamber is arranged in an inner boiler coaxial with the outer boiler, through the middle of which the burner tube is passed.
In Abb. i der Zeichnung ist ein Ausführungsbeispiel des Dampferzeugers im Üöhenschnitt, und in Abb.2 in einem teilweisen Horizontalsehnittdargestellt. Der ringförmige Außenkessel a birgt in seinem oberen Teile den gleichachsigen Innenkessel b, der durch Heiz- und Stützrippen c mit dem Außenkessel verbunden ist. In der Mitte des Innenkessels ist das Brennerrohr d befindlich. Das so geschützte Rohr kann nicht'- verbrennen, auch kann der Brennstaub in seinem Innern nicht zur Enfzündung kommen; da die -Wassertemperatur entweder unterhalb der Entflammungstemperatur des Staubes liegt, oder das Staubluftgemisch mit so niedriger Temperatur in das Brennerrohr eintritt, daß eine entsprechende Erwärmung nicht stattfinden kann.In Fig. I of the drawing is an embodiment of the steam generator in the Üöhenschnitt, and shown in Fig. 2 in a partial horizontal section. The upper part of the ring-shaped outer chamber a contains the equiaxed inner chamber b, which is connected to the outer boiler by heating and supporting ribs c. In the middle of the inner boiler is the burner tube d. The so protected pipe cannot burn, nor can the fuel dust inside it ignite come; because the water temperature is either below the ignition temperature of the Dust or the dusty air mixture with such a low temperature in the burner tube occurs that a corresponding heating cannot take place.
