Description
Rauchgasvorwärmer mit geneigt und versetzt zueinander liegenden Rippenrohren Die Erfindung bezieht sich auf einen Rauchgasvorwärmer mit geneigt und versetzt zueinander liegenden Rippenrohren für Speisewasser.Flue gas preheater with inclined and offset finned tubes The invention relates to a flue gas preheater with inclined and offset finned pipes lying opposite one another for feed water.
Das Neue der Erfindung besteht darin, daß die einzelnen wagerechten Rohrreihen an den mit Dichtung versehenen Endflanschen durch Zwischenstücke verschiedener Höhe verriegelt und die einzelnen Rohre jeder wagerechten Rohrreihe zwischen den Endflanschen mit Schautüren o. dgl. versehen sind. Der Vorwärmer erhält hierdurch einen vergrößerten Zugquerschnitt, der wiederum die Möglichkeit schafft, die Zuggeschwindigkeit ohne Erhöhung des Zugverlustes zu steigern. Die stete Veränderung des Zugquerschnittes veranlaßt die Gase zu einer dauernden Durchwirbelung und bringt die Gase zu einer innigen Berührung mit der Heizfläche. Trotz der geneigten Rohrlage sind die Abschlußwände sicher gegen Verschiebung verriegelt. Die Vergrößerung aller Querschnitte ermöglicht den Einbau einer innenliegenden Ausblasevorrichtung.The novelty of the invention is that the individual horizontal Rows of pipes on the end flanges provided with a seal by means of spacers of various types Locked height and the individual tubes of each horizontal row of tubes between the End flanges with inspection doors or the like are provided. This gives the preheater an enlarged train cross-section, which in turn creates the possibility of increasing the train speed without increasing the drag loss. The constant change in the train cross-section causes the gases to continuously swirl and brings the gases to one intimate contact with the heating surface. Despite the inclined pipe position, the end walls are locked securely against displacement. The enlargement of all cross-sections enables the installation of an internal blow-out device.
Die Erfindung wird in Abb. i, a, 3 beispielsweise dargestellt. Abb. i zeigt einen zusammengebauten Vorwärmer im Schnitt. Die Abschlußwand besteht aus den Flanschen der Rippenrohre a, welche wagerecht durch Schautürchen e oder gleich große Zwischenstücke c getrennt sind. Senkrecht werden die einzelnen Flanschen a und Türchen bzw. Zwischenstücke c durch die die Schräglage bedingenden Zwischenstücke b und d verriegelt. Diese Zwischenstücke haben verschiedene Höhen. Das größere, b, ist zweiteilig und ermöglicht das Auswechseln eines einzelnen schadhaften Rohres. Das kleinere Zwischenstück d ist einteilig. Beide Zwischenstücke besitzen Kragen, mit denen sie die Rohrflansche a und die Türchen e bzw. Zwischenstücke c gegen Verschieben sichern. Zwischen den Kragen befindet sich ein Dichtmittel!, welches ein Eindringen falscher Luft verhindert. Am Ende jeder wagerechten Reihe befindet sich in der Abschlußwand der Endfiansch eines festen oder beweglichen Deflektors. Die unteren und oberen Rippenrohre sind durch Sammelrohre f verbunden. Das zu erwärmende Wasser steigt kaskadenförmig durch schrägliegende Krümmer g nach oben.The invention is illustrated in Figs. I, a, 3, for example. Fig. I shows an assembled preheater in section. The end wall consists of the flanges of the finned tubes a, which are horizontally separated by viewing doors e or intermediate pieces c of the same size. The individual flanges a and doors or intermediate pieces c are locked vertically by the intermediate pieces b and d which cause the inclined position. These spacers have different heights. The larger, b, is in two parts and allows a single damaged pipe to be replaced. The smaller intermediate piece d is in one piece. Both intermediate pieces have collars with which they secure the pipe flanges a and the door e or intermediate pieces c against displacement. There is a sealant between the collar, which prevents the ingress of false air. At the end of each horizontal row there is the end flange of a fixed or movable deflector in the end wall. The lower and upper fin tubes are connected by manifolds f. The water to be heated rises in a cascade through inclined bends g upwards.
Abb. z zeigt einen Längsschnitt durch den zusammengebauten Vorwärmer. Auf Abb. i und z ist eine bewegliche Ausblasevorrichtung n eingestrich=elt. Abb. 3 zeigt die Verriegelung und Abdichtung der Abschlußwand.Fig. Z shows a longitudinal section through the assembled preheater. In Fig. I and z a movable blow-out device n is dashed in = elt. Fig. 3 shows the locking and sealing of the end wall.
Die auf den Abbildungen dargestellten Türchen e können durch gleichartige Zwischenstücke ohne Schaulöcher ganz oder teilweise ersetzt werden.The doors shown in the figures e can be replaced by similar Intermediate pieces without inspection holes can be replaced in whole or in part.
