Die Erfindung betrifft ein Heizrohr für Dampfkessel mit nach dem einen Ende zu abnehmender Weite, entsprechend der Abkühlung der Heizgase, welche in das weitere Ende des Rohres eintreten. Bei den bekannten kegelförmigen Heizröhren wird zugleich in jedem Querschnitt der innere Umfang des Rohres und dadurch die Wärmeabgabe verringert. Um diesem Übelstand abzuhelfen, wird nach der Erfindung das Heizrohr aus einem zylindrischen Rohr durch ein allmählich tiefer gehendes seitliches Einbiegen hergestellt, so daß es zwar, genau entsprechend der Zusammenziehung der Gase bei ihrer Abkühlung, allmählich nach dem einen Ende zu an Weite abnimmt und doch in jedem Querschnitt einen annähernd gleichen inneren Umfang beibehält.The invention relates to a heating pipe for steam boilers with one end closed decreasing width, corresponding to the cooling of the heating gases, which in the further Enter the end of the pipe. In the case of the known conical heating tubes, at the same time in each cross-section the inner circumference of the tube and thereby the heat dissipation is reduced. To remedy this evil, According to the invention, the heating tube is made from a cylindrical tube by gradually bending in deeper sideways manufactured so that it does indeed correspond exactly to the contraction of the gases at their cooling, gradually decreasing in width towards one end and yet approximately the same in every cross-section Maintains inner circumference.
Auf der Zeichnung ist eine Ausführungsform des neuen Heizrohres dargestellt, und zwar in Fig. I in einem Längsschnitt, in Fig. 2 in der äußeren Ansicht und in Fig. 3 bis 5 in Querschnitten nach A-A, B-B und C-C der Fig. 1 in vergrößertem Maßstabe.In the drawing, an embodiment of the new heating tube is shown, namely in Fig. I in a longitudinal section, in Fig. 2 in the external view and in Fig. 3 to 5 in cross sections according to AA, BB and CC of FIG. 1 in enlarged Scale.
Das Rohr besitzt an seinen beiden Enden zylindrische Teile α und b von geringer Länge, um es hier in den Rohrwänden zu befestigen; im übrigen hat das Rohr durch das allmählich tiefer gehende Einbiegen seiner Wandung nach innen die auf der Zeichnung veranschaulichte Gestalt angenommen.The tube has cylindrical parts α and b of short length at both ends in order to fasten it here in the tube walls; In addition, the tube has assumed the shape illustrated in the drawing due to the gradually deeper inward bending of its wall.
