Description

Wasserrohrkessel mit Schutzeinrichtung für die Verbindungsstellen der Siederöhren mit den Obertrommeln. Die Erfindung betrifft-Einrichtungen zum Schutze der Verbindungsstellen der Siederöhren mit den Obertrommeln an Wasserrohrkesseln, wobei die Schutzeinrichtung aus zwischen den Siederöhren eingeschobenen, diese umfassenden Schutzplatten besteht, -die auf an Siederöhren befestigten Tragringen ruhen.Water tube boiler with protective device for the connection points the boiler tubes with the top drums. The invention relates to devices for protection the connection points of the boiler tubes with the upper drums on water tube boilers, wherein the protective device is made of inserted between the boiler tubes, encompassing them There is protective plates, -which rest on support rings attached to boiler tubes.

Das- Neue der Erfindung besteht darin, daB die Tragringt eine Bohrung haben, die kleiner ist als der Durchmesser der Siederohre, und daB sie mit dieser Bohrung über die auf einen entsprechend kleineren Durchmesser eingestauchten oberen Enden der Siederohre gestreift sind und vom Übergangsvorsprung des eingezogenen Rohrteils gestützt werden. Die Erfindung unterscheidet sich hierdurch vorteilhaft von bekannten Schutzeinrichtungen dieser Art, bei denen auf den glatten Röhren ohne vorherige oder nachträgliche Formänderung der letzteren Ringe mittels Klemmung oder Schweißung festgehalten werden, die zum. Stützen einer feuerfesten Schutzschicht dienen. Gegenüber diesen bekannten Einrichtungen ist die neue Befestigung der Tragringe einfacher und schneller vorzunehmen, auch ergibt sich eine größere Haltharkeit der Befestigung während des Betriebes.The novelty of the invention is that the support ring has a bore which is smaller than the diameter of the boiler tubes, and that they go with this Hole over the upper one, which is indented to a correspondingly smaller diameter Ends of the boiler tubes are striped and drawn in from the transition projection Pipe part are supported. The invention differs in this way advantageously of known protective devices of this type, where on the smooth tubes without previous or subsequent change in shape of the latter rings by means of clamping or Welding be held on the. Supports a refractory Serve protective layer. Opposite these known facilities is the new attachment to make the support rings easier and faster, also results in a larger one Durability of the fastening during operation.

Die Zeichnung veranschaulicht ein. Ausführungsbeispiel der Erfindung in Abb. r im teilweisen Schnitt und in Abb. 2 in teilweiser Draufsicht im Schnitt nach. Linie A-B.The drawing illustrates a. Embodiment of the invention in Fig. r in partial section and in Fig. 2 in partial plan view in section after. Line A-B.

Abb. 3 zeigt einen Schnitt nach Linie C-D. Auf die eingezogenen Enden der Rohre z sind Ringe 2 aufgezogen oder aufgeschrumpft, deren Außenrand gegenüber den Rohren r vorspringt. Die durch die Ringe gebildeten Vorsprünge dienen zum Halten der aus Schamotte o. dgl. bestehenden Steine 3, deren abgerundete Ecken sich den Rohrenden anpassen. Die Stoßfugen der dicht aneinanderliegenden Steine bilden ein Gitterwerk, deren Linien die Mitten der Rohre z schneiden. Es ergibt sich so eine zusammenhängende wirksame Schutzschicht für die Verhindungsstellen der Rohrenden mit dem Kesselmantel 4. Bei Schadhaftwerden einzelner Steine können diese leicht und schnell von unten her ersetzt werden.Fig. 3 shows a section along line C-D. On the drawn-in ends the tubes z are rings 2 pulled on or shrunk on, the outer edge of which is opposite protrudes from the pipes r. The projections formed by the rings are used to hold of the chamotte o. The like. Existing stones 3, the rounded corners of which the Adjust pipe ends. The butt joints of the stones lying close together form a Latticework, the lines of which intersect the centers of the tubes z. There is such a thing coherent effective protective layer for the connecting points of the pipe ends with the boiler shell 4. If individual stones become damaged, they can easily and can be quickly replaced from below.
