Description

Die Erfindung betrifft scheibenförmige Einbauten im Flammrohr eines. Flammrohrkes,sel.s, die hintereinander und senkrecht zur Längsachse des Flammrohres angeordnet sind. Durch die Einbauten sollen Flugascheablagerungen verhindert und eine bessere Wärmeausnutzung der Rauchgase erreicht werden.The invention relates to disc-shaped internals in the flame tube of a. Flammrohrkes, sel.s, one behind the other and perpendicular to the longitudinal axis of the flame tube are arranged. Fly ash deposits are to be prevented by the internals and a better heat utilization of the flue gases can be achieved.

Es ist bekannt, daß durch einen kräftigen, unter längs - des Flammrohres ziehenden Rauchgasstrom Flugascheablagerungen verhindert werden .können. Die bisher bekannten Einbauten dieser Art verschließen die obere Hälfte des Flammrohres völlig; sie haben die Nachteile, daß durch die Verkleinerung des fireien Querschnittes des Flammrohres- der Zug wesentlich erhöht und die Rauchgase im oberen Teil des, Flammrohres völlig gestaut werden.: Andere Einbauten unterteilen den Rauchgasstrom in mehrere Einzelströme gleichen- Zuges; die Ablagerung von Flugasche wird aber durch diese- Einbauten !kaum verhindert. Auch ist die Befahrbarkeit des Flammrohres erst nach Entfernung oder Zerstörung der Einbauten möglich.It is known that by a strong, under the length of the flame tube pulling flue gas flow, fly ash deposits can be prevented. So far known internals of this type close the upper half of the flame tube completely; they have the disadvantages that by reducing the fireien cross-section of the Flame tube - the draft increases significantly and the smoke gases in the upper part of the flame tube be completely dammed .: Other installations divide the flue gas flow into several Single streams of the same train; the deposit of fly ash is, however, reduced by this Internals! Hardly prevented. The flame tube is also only passable after Removal or destruction of the fixtures is possible.

Die Erfindung beruht auf dem Gedanken, den Heizgasstrom in zwei Rauchgasströme aufzuteilen. Der untere Rauchgass,tro,m soll kräftiger als der obere Rauchgasstrom sein.. Der untere Rauchgas-Strom hindert das Absitzen der Flugasche. Der obere Rauchgasstrom wird nicht völlig gestaut. Die Anlage besteht aus in Abständen hintereinander angeordneten scheibenförmigen Wänden a, b, welche das Flammrohr zu zwei Drittel verschließen (Schnitt C-D). Die einzelnen Wände haben unten einen großen D.urchlaß, während diiebberen Durchlässe 2, 3, q. (Schnitt A-B) wesentlich kleiner sind. Durch die Abstufung der Durchlässe in ihrer Größe tritt im Flammrohr eine Abstufung des Zugs auf; die Hauptmasse der Rauchgase tritt durch den großen D.urchlaß i der Wände ct, b durch; der untere Durchlaß läßt einen stärkeren Strom als der obere Durchlag durch, welcher aus den kleinen Öffnungen. 2, 3, q. besteht. Der Oberstrom :ist zur Verwirbelung der Rauchgase unerläßlich.The invention is based on the idea of dividing the heating gas flow into two flue gas flows. The lower flue gas, tro, m should be stronger than the upper flue gas flow. The lower flue gas flow prevents the fly ash from settling. The upper flue gas flow is not completely dammed. The system consists of disc-shaped walls a, b, arranged one behind the other at intervals, which close the flame tube by two thirds (section CD). The individual walls have a large opening at the bottom, while the larger openings 2, 3, q. (Section AB) are much smaller. Due to the gradation of the passages in their size, a gradation of the draft occurs in the flame tube; the bulk of the smoke gases pass through the large passage i of the walls ct, b ; the lower passage allows a stronger flow than the upper passage, which is from the small openings. 2, 3, q. consists. The overflow: is essential for the swirling of the flue gases.
