Description

Einsatzkörper für Flammrohre von Kesseln Es sind Einsatzrohre für Flammrohre von Kesseln. mit auf einem als Luftzuführungsrohr dienenden Mittelstück aufgesetzten schraubenförmigen Flügeln bekannt.Insert bodies for flame tubes of boilers These are insert tubes for Fire tubes of boilers. with a middle piece serving as an air supply pipe attached helical wings known.

Nach der Erfindung sind die Flügel aus einzelnen hohlen Segmentkörpern zusammengesetzt, deren Hohlraum mit dem Luftrohr in Verbindung steht. Die bekannte Zusammensetzung der Flügel aus einzelnen Segmentkörpern. gestattet einen leichten Einbau und eine einfache Auswechselung der Einsätze. Die hohle Ausbildung der Flügel, die bei aus einem Stück bestehenden Schraubeneinsätzen ebenfalls bekannt ist, ermöglicht außerdem eine Kühlung der einzelnen Segmentkörper; wodurch deren. Betriebsdauer gegenüber den vollwandigen geteilten Segmentkörpern erhöht wird. Durch die Anordnung von Ausströmöffnungen an den Flügeln läßt sich ferner eine weitgehende Verteilung des dann als Zusatzluft dienenden hocherhitzten Kühlmittels in dem Flammrohr erzielen.According to the invention, the wings are made up of individual hollow segment bodies composed, the cavity of which is in communication with the air tube. The well-known Composition of the wings from individual segment bodies. allows an easy Installation and easy replacement of the inserts. The hollow formation of the wings, which is also known in the case of screw inserts consisting of one piece, enables also a cooling of the individual segment bodies; whereby their. Operating time is increased compared to the full-walled divided segment bodies. By the arrangement extensive distribution of outflow openings on the wings can also be achieved of the highly heated coolant then serving as additional air in the flame tube.

Die Erfindung ist auf der Zeichnung in einem Ausführungsbeispiel. dargestellt: In dem Flammröhr a des Kessels b ist eine Schnecke angeordnet, die aus den hohlen Teilsegmenten c, cx, c2 besteht. Durch Nasen oder Aussparungen lassen sich die Naben mittels einer Ankerschraube vereinigen. An dem offen bleibenden Ende dies hohlen Hernes ist ein. Luftrohr g angeschlossen, welches nach dem Fuchsende hinausgeführt wird .oder aber auch, durch den Aschfall der Feuerung hindurchgeführt, vor dem Heizerstande münden kann. Die Hohlräume der einzelnen Segmente stehen mit dem Hohlraum des Kernes oder Luftrohres in Verbindung.The invention is shown in the drawing in one embodiment. shown: In the flame tube a of the boiler b a screw is arranged, which consists of the hollow subsegments c, cx, c2. The hubs can be joined by means of an anchor screw through noses or recesses. At the end of this hollow hernia that remains open is a. Air pipe g connected, which is led out after the end of the fox. Or, however, also, led through the ash fall of the furnace, can open out in front of the stoker's position. The cavities of the individual segments are connected to the cavity of the core or air tube.
