Rahmenartige Rohrkammer als Durchstiegöffnung in einer Tragrohrwand, die z.B. zur Halterung von Überhitzerrohren o.dgl. dient. Frame-like tube chamber as a through opening in a support tube wall, which, for example, for holding superheater tubes or the like. serves.
Bekanntlich werden die Rohrpakete von Überhitzern, Vorwärmern u.dgl. an gekühlten Tragrohren aufgehängt, die in bestimmten Abständen voneinander in vertikalen Ebenen verlaufen und mit Ansätzen zur Auflage der schlangenförmigen Überhitzer o.dgl. Rohre versehen sind.It is well known that the tube packages of superheaters, preheaters and the like are suspended from cooled support tubes, which run at certain distances from each other in vertical planes and with approaches to support the serpentine superheater or the like. Pipes are provided.
Zwischen den einzelnen Rohrpaketen sind befahrbare Zwischenräume vorgesehen, die von Öffnungen in der Wand des Gaszüges aus zugänglich sind.Accessible spaces are provided between the individual pipe packages, from openings in the wall of the throttle cable are accessible.
Um die Rohrpakete bequem befahren zu können müßen in den Tragrohrwänden entsprechendbemessene Durchstiegöffnungen"Wg?sehen sein, die bisher durch seitliches Ausbiegen einiger der Tragrohre gebildet werden.In order to be able to comfortably drive on the tube stacks, appropriately dimensioned walls must be installed in the supporting tube walls Access openings "Wg? See that previously formed by bending some of the support tubes sideways.

Zur Aufnahme der Biegungsbeanspruchung, die zusätzlich zur Zugbeanspruchung durch das Ausbiegen der Tragrohre in ihnen entsteht, werden flache Zwischenstege zwischen die benachbarten geraden und ausgebogenen Rohre eingeschweißt. Durch diese Anordnung werden jedoch die Biegungskräfte in den ausgebogenen Rohren nur zum Teil aufgenommen, und es besteht die Gefahr, daß die Zwischenstege nicht ausreichend gekühlt werden, und damit ihre Festigkeit verlieren, wenn, die aufgenommene Wärme nicht in genügender Weise in die gekühlten xlohre abgegeben werden kann.To absorb the bending stress, the additional for tensile stress caused by the bending of the support tubes in them, flat intermediate webs are between welded in the adjacent straight and curved tubes. However, this arrangement only partially absorbs the bending forces in the bent tubes. and there is a risk that the intermediate webs are not sufficiently cooled, and thus their strength lose if the absorbed heat is not given off sufficiently into the cooled xlohre can.
Ss ist ferner bekannt zur Erzielung einer Durchstiegöffnung eine ringförmige Kammer zu verwenden, in die die unterbrochenaiTragrohre eingeschweißt werden. Da die Kammer ebenfalls einer Bieguiigsbeanspruchung unterliegt, so muß ihre Wandstärke entsprechend bemessen werden. Auch das Einschweißen der Rohre erfolgt zweckmäßig über Zwischennippel oder Rohrgabelungen, daher ist diese Lösung relativ kostspielig. Gemäß der Neuerung wird anstelle einer ringförmigen oder aus zwei Halbringen bestehende Kammer ein Rohrviereck verwendet, in dessen waagerechte Rohre die unterbrochenen Tragrohre eingeschweißt sind, und dessen senkrechte'Rohre in Achsrichtung der außen liegenden unterbrochenen Tragrohre verlaufen. In der Mitte der waagerechten Rohre werden zweckmäßig Trennwände eingesetzt, die nicht abzudichten brauchen.Ss is also known to achieve an access opening to use an annular chamber into which the interrupted support tubes are welded. Since the Chamber is also subject to bending stress, so their wall thickness must be dimensioned accordingly. The tubes are also expediently welded in via Intermediate nipples or pipe bifurcations, hence this one Solution relatively expensive. According to the innovation, instead of one ring-shaped or two half-rings Chamber uses a square tube, in whose horizontal tubes the interrupted support tubes are welded are, and whose vertical tubes run in the axial direction of the interrupted support tubes on the outside. Partition walls that do not need to be sealed are expediently placed in the middle of the horizontal pipes.
In der Zeichnung ist die Neuerung in Draufsicht auf eine Tragrohrwand dargestellt. Die durch die Binstiegöffnung a unterbrochenen Tragrohre 3 an denen die Überhitzerrohre 2 o.dgl. abgestützt sind, münden oben in einen horizontal liegenden Kammerteil 4 und verlassen unten einen zweitenIn the drawing, the innovation is in plan view of a Support tube wall shown. The support tubes 3 interrupted by the access opening a on which the superheater tubes 2 or the like. are supported, open at the top in a horizontally lying chamber part 4 and leave a second below

horizontal angeordneten Kaimnerteil 5 bzw. Verteiler. Beide Kammerteile sind etwa in Achsrichtung der äußeren unterbrochenen Tragrohre J bzw. 5" über Zwischenrohre 6, 7 zu einem Viereck verbunden. Diese Anordnung ist bequem herzustellen und von besonderer Stabilität. Die horizontal angeordneten Kammerteile 4 und 5 können auch unterhalb der Enden der Kammerteile 6, 7 eingeschweißt sein, wobei letztere auf den'Durchmesser der Tragrohre 3> 3" konisch eingezogen und durch eine Hundnah t mit ihnen verschweißt werden können. Es brauchen alsdann die Enden der horizontalen Kammerteile 4, 5 nicht besonders verschlossen werden. Es ist auch möglich, die lak.en jeweils zweier gegenüberliegender Kammern durch Äundbögen zu ersetzen, so daß ein Kammerviereck mit abgerundeten Ecken entsteht.horizontally arranged chamber part 5 or distributor. Both chamber parts are approximately in the axial direction of the outer interrupted support tubes J or 5 "via intermediate tubes 6, 7 connected to form a square. This arrangement is Easy to manufacture and particularly stable. The horizontally arranged chamber parts 4 and 5 can also be welded below the ends of the chamber parts 6, 7, the latter being based on the diameter of the Support tubes 3> 3 "drawn in conically and through a Hundnah t can be welded to them. The ends of the horizontal chamber parts 4, 5 then need it not particularly locked. It is also possible to paint the two opposing chambers to be replaced by Äundbogen, so that a chamber square with rounded corners is created.
