Description

Zweiflammrohrkessel mit schraubenförmig gerippten Einsatzkörpern in den Flammrohren. Die Erfindung betrifft einen Zweiflammrohrkessel, in dessen Flammrohre je ein Einsatzkörper mit schraubenförmig verlaufenden Rippen eingebaut ist, der den durchströmenden Heizgasen eine drehende Bewegung erteilt. Da die Heizgase die Flugasche mitreißen, wird diese am hinteren Flammrohrende seitwärts herausgeschleudert und hinter dem einen Rohr gegen die Trennmauer geworfen, wo sie sich anstaut und den Gasdurchgang ver-;..topft.Double-flame tube boiler with helically ribbed insert bodies in the flame tubes. The invention relates to a two-flame tube boiler, in the flame tubes an insert body with helically extending ribs is installed, the the heating gases flowing through are given a rotating movement. Since the heating gases the If fly ash is carried away, it is thrown sideways at the rear end of the flame tube and thrown behind the one pipe against the separating wall, where it accumulates and the gas passage -; .. pots.

Gemäß der Erfindung sind nun die in den beiden Flammrohren angeordneten Führungskörper im Gegensatz zu den bisherigen Einsätzen derart ausgebildet, daß die Rippen des einen Einsatzkörpers Rechtsdrall -and die des anderen Linksdrall haben, wodurch den beiden Gasströmen eine solche Drehbewegung erteilt wird, daß de mitgerissene Flugasche an den Flammrohrenden nach außen in die Seitenzüge des Kessels geschleudert wird, wo genügend Platz zur Ablagerung vorhanden und das Entfernen .der Asche leicht möglich ist.According to the invention are now arranged in the two flame tubes In contrast to previous inserts, guide body is designed in such a way that the ribs of one insert body right-hand twist and those of the other left-hand twist have, whereby the two gas streams are given such a rotary motion that de entrained fly ash at the ends of the flame tube outwards into the side pulls of the Boiler is thrown where there is enough space for deposit and removal .the ashes are easily possible.

Auf der Zeichnung ist, ein mit der neuen Heizgasführung versehener Zweiflammrohrkessel in Abb. i im Längsschnitt, in Abb. 2 @zn Querschnitt und in Abb.3 im Grundriß dargestellt.The drawing shows a one with the new heating gas system Two-flame tube boiler in Fig. I in longitudinal section, in Fig. 2 @zn cross-section and in Fig.3 shown in plan.

Die Steine 1, 2 sind ein kurzes Stück hinter der Feuerung in die Flammrohre 3, 4 des Kessels eingebaut. Die schraubenförmigen Rippen der Steine haben zunehmende Steigung und werden nach hinten hin entsprechend dem größer werdenden Kerndurchmesser niedriger. Die Steine können aus einzelnen zusammenzusetzenden Stücken bestehen, deren Zahl der Zahl der Rippen entspricht, wobei auf jedem Teilstück sich eine Rippe befindet. Sie werden vornehmlich exz-ntrisch in die Rohre 3, q. eingebaut, beispielsweise unter Benutzung von unter ihnen vorgesehenen Stützen oder durch exzentrische Anordnung des Mittelkerns zu den Rippen.The stones 1, 2 are a short distance behind the furnace in the flame tubes 3, 4 of the boiler installed. The helical ribs of the stones have increasing Slope and are backwards according to the increasing core diameter lower. The stones can consist of individual pieces to be put together, the number of which corresponds to the number of ribs, with one rib on each section is located. They are mainly eccentrically in the tubes 3, q. built in, for example using supports provided below them or by eccentric arrangement of the central core to the ribs.

Die schraubenförmigen Rippen der beiden Steine haben verschiedenen Drall, und zwar der Stein i Rechts- und der Stein 2 Linksdrall. Hierdurch wird die von den in Drehung versetzten Heizgasen mitgerissene Flugasche am Ende der Rohre in die Seitenzüge 9, io geworfen, da die aus den Rohren austretenden, in Drehung befindlichen Ascheteilchen an den Außenseiten auf ihrem Wege nach oben hin unter dem Einfluß der Schwerkraft abreißen und zu Boden fallen.The helical ribs of the two stones have different ones Twist, namely the stone i right-hand twist and the stone 2 left-hand twist. This will make the Fly ash entrained by the rotating heating gases at the end of the pipes thrown into the side moves 9, io, since the ones emerging from the pipes are rotating ash particles located on the outside on their way upwards tear away under the influence of gravity and fall to the ground.
