Description

Wendelförmiger Leitkörper für Rauchrohre Ec ist bekannt, Rauchrohre in Heizkesseln nit wendelförmigen leitfidc:ie2z zu versehen, um dem Hauchbas einen Drall und eine Bolle Geschwindigkeit zu verleihen und wo den Wärmeübergang und damit den Gesamtwirkungsgrad zu verbessern. iIierbei c@"erden viel- iach Leitkörper mit wendelförmig um einen Kern verlaufender Leit- fLIche verwendet, die zu mehreren hintereinander in das Rauchrohr eingesetzt werden, derart daß die Leitflächen der einzelnen Leit- körper stetig ineinander übergehen. Diese Anordnung, bei der das Rauchrohr Leist auf die ganze Länge von Leit,c*rpern ausgefüllt ist, hat den Nachteil, daß der Strö- ..uat@s:"il',erstard in Rauchrohr zier lic?i noc'i isfi, was auf die Grös- se und .Leistung des Brenners einen wesentlichen Einfluß hat. Per- :--er kommt es in den kälteren Zonen am Ende des Rauchrohres zu 1aßaiederschlag ar, Gen Leitkörpern, was der. "#i;-#rneilbergang ver- schlechtert und ein häufiges Säubern des Kessels erfordert. Aus- serde._i können sich die heitkörper selbst bei nur schwachen Ver- puffungen so verlagern, daß die Kontinuität der Leitilächeii ver- lorengeht und der Strömunrsiqiderstand weiter ansteigt. Die Erfindun,-; vermeidet diese Nachteile und betrifft einen Leit- körper mit wendelförmig um einen Kern Leiiä.e'' zum Einbau in Rauchrohre von Ieizkesseln-, der sichi da ur'`;ä zeichnet, daß die Steigung der wendelförnigen Leitfl.gcle vul3 h.- trittsende aus allmählich auf den gewünschten alert abriimmt*und"@' gegebenenfalls zum Austrittsende hin diesen Wert über binl:ge =r@°` Windungen beibehält. Durch diesen Leitkörper werden die Rauchgase ,1q Rauchrohr. g13,- , mählich auf den gewünschten Drall beschleunigt, ,das einen gern- fieren Staudruck und einen gleichmäßigeren Te'r:per' aturaebau' zur Folge hat. Da, wie sich gezeigt hat, die Rauchgase de nihnen ex- teilten Drall auch noch hinter dem Leitkörper beibeha,lteri, " braucht der Zeitkörper nach der Erfindung nur der. vorderen Teil des Rauchrohres auszufüllen, während der hintere Teil frei von Einbauten bleiben kann. Damit wird der Strömungswiderstand für das Rauchgas weiter vermindert und es ergeben sich kleinere Bren- nergrö?.ei-, und iIeizräu:^e und ein wesentlich geringerer Kostenhuf- wand für Leitkörper. Ferner kann im kälteren Rohrteil. kein Buß- niederschlag an Wendelflächen erfolgen. Au1?erdem sind ge";ensei- tige Verlagerungen von Leitkörper:: ausgeschlossen. In der ZeichnunG ist der Zeitkörper nach der Erfindung darge- stellt, und zwar in fig. 1 als Leitkörper aus Metall in Ansicht vnd in Fig. 2 als Leitkörper aus Keramik im Schnitt. Gemäß Fit;. 1 ist der Kern des Zeitkörpern ein an einem Ende oder an beiden Enden verschlossenes Stahlrohr 1, äuf dem eine Wendel 2 aus Blech befestigt, z.B. aufgeschweißt ist. Diese Wendel besitzt a. rechten Ende des Leitkörpere, an dem die Rauchase eintreten, eine große Steigung, von z.B. 110 a®, die stetig abnimmt und hier nach zwei Windungen ihren Entwert, von z. B. 55 mm, erreicht hat, den sie über zwei Windungen beibehält. Der Leitkörper hat mit den beispielsweise genannten Zahlenwerten eine Gesamtlänge von etwa 300 mm bei einen Durchaeseer von 80 aea und ist in dieser Größe für den Einbau in den vorderen Teil ei- nes Rauchrohres von z.B. etra 2 000 mm. Länge .geeignet.Helical guide body for smoke tubes Ec is known to have nit helical smoke pipes in boilers leitfidc: ie2z to give the Hauchbas a twist and a Bolle to give speed and where the heat transfer and thus improving the overall efficiency. iIier bei c @ "earth iach guide body with helically around a core guide Area used, several in a row in the smoke pipe are used in such a way that the guide surfaces of the individual guide bodies steadily merge into one another. This arrangement in which the flue pipe runs along the entire length is filled in by leaders, has the disadvantage that the flow ..uat @ s: "il ', erstard in flue pipe zier lic? i noc'i isfi, what is the size se and .performance of the burner has a significant influence. By- : - it occurs in the colder zones at the end of the smoke pipe 1aßaiederschlag ar, gene guide bodies what the. "#i; - # rneilbergang ver deteriorates and requires frequent cleaning of the boiler. The end- serde._i can even with only weak shift puffing so that the continuity of the Leitilächeii goes down and the flow resistance continues to rise. The invention -; avoids these disadvantages and concerns a body with helical shape around a core Leiiä.e '' for installation in flue pipes of heating boilers, which is located there ur'`; Ä shows that the slope of the helical guide surface gcle vul3 h.- stepping off gradually decreases to the desired alert * and "@ ' if necessary, set this value towards the exit end via binl: ge = r @ ° ` Maintains turns. The flue gases, 1q flue pipe, pass through this guide body. g13, -, gradually accelerated to the desired twist, which reduce back pressure and a more even tar: per 'aturaebau' for Consequence. Since, as has been shown, the flue gases from you ex- shared twist also behind the guide body retained, lteri, " only needs the time body according to the invention. front part of the smoke pipe to be filled in, while the rear part is free of Built-in can remain. The flow resistance for the flue gas is further reduced and there are smaller burns nergrö? .ei- and iIizräu: ^ e and a much lower cost wall for guide body. Furthermore, in the colder pipe part. no penance Precipitation occur on helical surfaces. In addition, there are term displacements of guide elements :: excluded. In the drawing the time body according to the invention is shown represents, namely in fig. 1 as a guide body made of metal in view and in Fig. 2 as a guide body made of ceramic in section. According to Fit .; 1 is the core of the time body one at one end or steel pipe 1 closed at both ends, one of them Helix 2 is fastened from sheet metal, for example welded on. These Wendel owns a. right end of the guide body, at which the smoke gases enter, a large slope, for example 110 a®, which steadily decreases and here after two turns its devaluation, from z. B. 55 mm, which it maintains over two turns . The guide body has with the example values mentioned, a total length of about 300 mm at a Durchaeseer of 80 aea and of this size to be installed in the front of egg nes smoke pipe of eg etra 2 000 mm. Length .suitable.

Gemäß Pig. 2 ist der Leitkörper aus Schamotte in einem Stich ge- formt und gebrannt ,. wobei die Leittläche 3 aua 1"estigkeitagrunden -einen dreieckigen Querschnitt beeitxt und der zylindrische Kern 4 für Befeetigungsswecke einen axialen Hohlraum besitzt.According to Pig. 2, the guide body of fireclay in a stitch is overall formed and fired. The guide surface 3 also has a triangular cross-section and the cylindrical core 4 has an axial cavity for fastening purposes.

Im übrigen können die Abmeesu»gen denen des Leitkörpers nach Fie. 1 entsprechen. In addition , the dimensions can be compared to those of the guide body according to Fie. 1 correspond.
