Anordnung an direkt geheizten Zellstoffkoehern mit inwendigem Umlauf.
Die Erfindung betrifft Zellstoffkocher, bei denen der Heizdampf einer innerhalb des Kochers angeordneten Vorrichtung zugeführt wird. der einen Teil einer inwendigen Umlaufleitung bildet.
Die Erfindung bezweckt. eine einfache und zweckentsprechende Befestigung für diese Vorrichtung und für die Leitung, mittels welcher Dampf zu der Vorriehtung geführt wird, zu schaffen.
Die Lösung dieser Aufgabe hat wegen der grossen Zerbrechlichkeit und des hohen Wärmeaus- dehnungskoeffizienten der Materialien, säurefester Stahl, die für einige Teile der Anordnung verwendet werden müssen, verschiedene praktische Schwierigkeiten geboten.
Gemäss der Erfindung wird eine einfache und sichere Befestigung geschaffen, welche freie Be eg-

Arrangement on directly heated pulp boxes with internal circulation.
The invention relates to cellulose digesters in which the heating steam is fed to a device arranged inside the digester. which forms part of an internal circulation line.
The invention aims. to create a simple and appropriate attachment for this device and for the line by means of which steam is fed to the Vorriehtung.
The solution to this problem has presented various practical difficulties because of the great fragility and the high coefficient of thermal expansion of the materials, acid-proof steel, which must be used for some parts of the arrangement.
According to the invention, a simple and secure attachment is created, which free Be eg-
