 abgegeben haben. Der Verschleiss der Heizrohre wird dadurch herabgesetzt und die Gefahr des
Rohrrinnens weitgehend beseitigt. 



   Gemäss einer bevorzugten Ausführungsform wird der Drosselquerschnitt von einem ein- gesetzten Ring gebildet, so dass der Durchmesser des Heizrohres selbst nicht verändert wird. 



   Der auf dem Heizrohr im Bereich der Rauch- kammerwand festgelegte, vorzugsweise auf das- selbe aufgeschrumpft Ring verstärkt das ver- hältnismässig dünnwandige Heizrohr und ver- grössert seinen Durchmesser an dieser Stelle, so dass ein leichtes Einführen des Heizrohres in den
Kessel möglich ist, ohne dass ein wesentliches Auf- weiten des Heizrohres beim Einwalzen erfor- lich wird. 



   In der Zeichnung ist die Erfindung an Hand eines Ausführungsbeispieles schematisch erläutert. 



   Das im Längsschnitt dargestellte Heizrohr   1   ist bei 2 in bekannter Weise in der Feuerbüchs- wand 3 festgelegt. 



   Vor der Austrittsstelle der Rauchgase aus dem
Heizrohr in die Rauchkammer ist ein Drossel- querschnitt in Form eines Ringes 4 im Heizrohr angeordnet. Durch diese Anordnung des Drossel- querschnittes wird ein günstiger Wärmeübergang erzielt und eine Expansion der Rauchgase im Heizrohr, wie sie bei einer Drosselquerschnittsanordnung an einer anderen Stelle, z. B. an der   Rauchgaseintrittsstelle   auftreten würde, vermieden. 



   Ein auf das Heizrohr aufgeschrumpfter Ring 5 verstärkt dieses im Bereich der Rauchkammerwand 6 und ermöglicht so ein einfaches Einführen des Heizrohres in den Kessel.

 have given up. The wear and tear on the heating pipes is reduced and the risk of
Pipe gutters largely eliminated.



   According to a preferred embodiment, the throttle cross-section is formed by an inserted ring so that the diameter of the heating pipe itself is not changed.



   The ring fixed on the heating pipe in the area of the smoke chamber wall, preferably shrunk onto the same, reinforces the comparatively thin-walled heating pipe and enlarges its diameter at this point, so that the heating pipe can be easily inserted into the
Boiler is possible without the need for a substantial expansion of the heating pipe during rolling.



   The invention is illustrated schematically in the drawing using an exemplary embodiment.



   The heating tube 1 shown in longitudinal section is fixed in the firebox wall 3 at 2 in a known manner.



   Before the exit point of the smoke gases from the
A throttle cross-section in the form of a ring 4 is arranged in the heating tube in the heating tube. Through this arrangement of the throttle cross-section, a favorable heat transfer is achieved and an expansion of the flue gases in the heating pipe, as is the case with a throttle cross-section at another point, e.g. B. would occur at the flue gas inlet point, avoided.



   A ring 5 shrunk onto the heating pipe reinforces it in the area of the smoke chamber wall 6 and thus enables the heating pipe to be easily inserted into the boiler.

PATENTANSPRUCH : Heizrohr für Dampfkessel od. dgl., gekennzeichnet durch die Kombination der Massnahmen, dass das über seine ganze Länge einen gleichbleibenden Aussen-und Innendurchmesser aufweisende Rohr an dem der Rauchkammer zugekehrten Ende, zweckmässig im Bereich der Verbindung mit der Kesselwand, durch einen aufgesetzten Ring verstärkt ist und dass es nahe der Austrittsstelle der Rauchgase innen einen einzigen Drosselquerschnitt aufweist. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Heating pipe for steam boiler or the like, characterized by the combination of the measures that the pipe, which has a constant outer and inner diameter over its entire length, is reinforced by an attached ring at the end facing the smoke chamber, expediently in the area of the connection with the boiler wall and that it has a single throttle cross-section on the inside near the exit point of the flue gases. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
