Description
Die Erfindung betrifft einen Schlangenrohr-Speisewasser-Vorwärmer, bestehend aus zu einander parallelen Rohrtafeln mit waagerechtem Rohrverlauf, deren einzelne gerade Stücke durch Bogen zu einem Rohrstrang verbunden sind, und besteht darin, daß das Bogenstück zum Teil in die entsprechende Ausbuchtung eines Kastens hineinreicht, an dem es vorzugsweise durch Schweißung befestigt ist, und daß die Kästen entsprechend der Rohrleitung geformt sind und gegebenenfalls unter Zwischenlage von Dichtstreifen eine gasdichte Wand bilden.The invention relates to a coiled pipe feed water preheater, consisting of pipe panels parallel to each other with a horizontal pipe run, their individual straight pieces are connected by bends to form a pipe string, and consists in that the bow piece in part in the corresponding bulge of a box extends, to which it is preferably attached by welding, and that the Boxes are shaped according to the pipeline and optionally with an intermediate layer of sealing strips to form a gas-tight wall.
Es ist bekannt, bei mit Querrippen versehenen, in lotrechten Ebenen liegenden Rohrschlangen vor den Bögen größere Tragflanschen vorzusehen, welche unter Zwischenlage von Dichtstreifen eine gasdichte Wand bilden. Bei nicht berippten Rohrschlangen ist c:er Heizflächenverlust, der bei dieser Ausführung durch die nicht beheizten Bogenstücke entsteht, zu groß. Daher wird gewöhnlich der Krümmer mitbeheizt und mit einem hakenartigen Fortsatz auf eine Tragleiste im Heizgaszug aufgelagert. Diese Tragleisten sind aus Metall und verzundern rasch.It is known to have transverse ribs in perpendicular planes lying pipe coils in front of the arches to provide larger support flanges, which under Between layers of sealing strips form a gas-tight wall. With non-ribbed pipe coils is c: he loss of heating surface, which in this version is due to the unheated Elbows emerge, too big. Therefore, the manifold is usually also heated and superimposed with a hook-like extension on a support strip in the heating gas flue. These Support rails are made of metal and scale quickly.
In den Abb. 1, 2 und 3 ist eine Ausbildung gemäß der Erfindung in drei Projektionen dargestellt. Die tiebeneinanderliegenden Rohrtafeln 1, 2, 3 bestehen je aus mehreren waagerechten Rohrstücken 4, 5, 6, 7, die an ihren Enden durch Bogenstücke 8, 9 verbunden sind. Jedes Bogenstück liegt zum Teil in einer Vertiefung 12 eines kastenförmigen Teils io mit nach außen gerichteten Wänden i i, der die Breite einer waagerechten Rohrteilung und die ganze Höhe der Rohrschlangen hat. An diesen Kästen sind die Bogenstücke 8, 9 durch Schweißraupen 13 befestigt.In Figs. 1, 2 and 3, an embodiment according to the invention in three projections shown. The pipe panels 1, 2, 3 lying one on top of the other are made each from several horizontal pipe pieces 4, 5, 6, 7, which are at their ends by elbows 8, 9 are connected. Each bend is partly in a recess 12 of a box-shaped part io with outwardly facing walls i i, which is the width of a horizontal pipe division and the full height of the pipe coils. At these boxes the curved pieces 8, 9 are fastened by welding beads 13.
Gemäß Abb. 4 reichen die Bogenstücke 8 durch eine entsprechende Öffnung in den Kasten io. Die Seitenwände i i der Kästen io liegen unmittelbar aneinander und schließen nur in ihrem äußersten Teil eine Fuge 14 ein, welche mit einer Asbestschnur 15 ausgefüllt wird.According to Fig. 4, the bow pieces 8 extend through a corresponding opening in the box io. The side walls i i of the boxes io are directly adjacent to one another and only in their outermost part include a joint 14, which is made with an asbestos cord 15 is filled out.
Nach Abb. 5 ist ein Kasten io gemeinsam für alle übereinanderiiegenden Bogenstücke einer Röhrtafel. Hierdurch wird der Transport zur und der Zusammenbau auf der Montagestelle sehr erleichtert. Werden Einzelkästen benutzt, so muß einschließlich Dichtleiste ein Kasten die Höhe der doppelten Rohrteilung haben, weint die ganze Rohrschlange mit gleichbleibendem Biegungsradius ausgeführt ist. Es kann vorkommen, daß die beschriebene Auflagerung nur auf einer Seite des Gaszugs benötigt wird, wo sie zugleich die Außenwand bildet, während auf der anderen Seite die Rohre in an Sich bekannter Weise mittels angeschweißter baken auf Leisten gelagert werden, welche an den Tragrohren von Zuglenkwänden befestigt sind.According to Fig. 5, a box io is common for all superimposed Elbow pieces of a tube board. This facilitates transportation to and assembly very relieved on the assembly site. If individual boxes are used, then including Sealing strip have a box the height of double the pipe division, the whole weeps Coiled pipe is designed with a constant bending radius. It can happen, that the support described is only required on one side of the throttle cable, where it at the same time forms the outer wall, while on the other side the pipes in be stored on bars in a known manner by means of welded-on beacons, which are attached to the supporting tubes of the pull-steering walls.
