Description

Dampferzeuger mit drei nebeneinanderliegenden Oberkesseln. Bei den üblichen Dampferzeugern mit mehreren nebeneinanderliegenden, durch Röhrenbündel miteinander verbundenen Oberkesseln sind die Röhrenbündel gewöhnlich durch Unterkessel unterbrochen. Daraus ergibt sich der übelstand, daß der außerhalb der Oberkessel stattfindende Wasserumlauf Querschnittsveränderungen unterworfen ist, da sich im Unterkessel der Querschnitt des Wasserumlaufes plötzlich erweitert, um sich beim Eintritt in das aufsteigende Röhrenbündel wieder zu verengen. Es entsteht dadurch die Gefahr, daß die Wasserröhren beim Austritt aus den Unterkesseln nicht gleichmäßig mit umlaufendem Wasser versorgt werden und die niche genügend mit Wässer beschickten Röhren durchbrennen.Steam generator with three adjacent upper boilers. Both usual steam generators with several side by side, through tube bundles Upper boilers connected to one another are the tube bundles usually through lower boilers interrupted. From this arises the evil that the outside of the upper boiler occurring water circulation is subject to cross-sectional changes, since in Lower boiler the cross-section of the water circulation suddenly expands in order to become Narrow entry into the ascending tube bundle again. It arises from it the Danger of the water pipes emerging from the lower boilers not evenly supplied with circulating water and not enough burn through pipes filled with water.

Bei dem den Gegenstand vorliegender Erfindung bildenden Dampferzeuger ist dieser übelstand. dadurch vermieden, daß in die die Oberkessel miteinander verbindenden Röhrenbündel keine Unterkessel eingeschaltet sind, sondern der Wasserumlauf durch im Querschnitt dauernd gleichmäßige V-förmige Röhrenbündel erzielt wird. Es bleiben somit alle Röhren gleichmäßig mit Wasser beschickt, und es ist die Gefahr des Durchbrennens einzelner Röhren beseitigt.In the steam generator forming the subject of the present invention is this evil. thereby avoided that in the interconnecting the upper boiler Bundles of tubes no lower boiler are switched on, but the water circulation through Constantly uniform V-shaped tube bundle is achieved in cross-section. It stays thus all tubes are evenly charged with water and there is a risk of burning through individual tubes eliminated.

Auf der Zeichnung .ist ein Ausführungsbeispiel der Erfindung dargestellt.On the drawing .is an embodiment of the invention is shown.

Der Dampferzeuger hat drei Oberkessel a, b, c, die durch zwei V-förmig gebogene Röhrenbündel c, d',, f :und c', d', f' verbunden sind. Die Oberkessel sind außerdem durch Ausgleichröhren k verbunden. Die scharfen Krümmungend,d' der V-förmigen Röhrenbündel werden durch das Mauerwerk i der unmittelbaren Einwirkung der von der Feuerung g aufsteigenden Heizgase entzogen. Im übrigen wird der schräge Teil/ des linken RöhrenE nürrdels und der senkrechte Teil c' des rechten Röhrenbündels durch. die Feuerung g stärker beheizt als die anderen Röhrenbündelteilec. und f', so daß der Wasserumlauf in den beiden V-förmigen Röhrenbündeln im Sinne der eingezeichneten Pfeile in entgegengesetzter Richtung erfolgt. Die V-förmigen Röhrenbündel haben auf ihrer ganzen Länge gleichen, Querschnitt und werden durch keinerlei Unterkessel o, dgl. unterbrochen.The steam generator has three upper boilers a, b, c, which are connected by two V-shaped tube bundles c, d ',, f: and c', d ', f'. The upper boilers are also connected by equalizing pipes k. The sharp curvatures d 'of the V-shaped tube bundle are withdrawn from the direct action of the hot gases rising from the furnace g by the masonry i. In addition, the oblique part / of the left tube E nürrdels and the vertical part c 'of the right tube bundle through. the furnace g heated more than the other tube bundle parts c. and f ', so that the water circulation in the two V-shaped tube bundles takes place in the opposite direction as indicated by the arrows. The V-shaped tube bundles have the same cross-section over their entire length and are not interrupted by any undercells or the like.

PATENTANSPRUCH: Dampferzeuger mit drei nebeneinanderliegenden Oberkesseln, die durch Röhrenbündel miteinander verbunden sind, dadurch gekennzeichnet, daß der mittlere Oberkessel (h) mit den beiden äußeren Oberkesseln (a, c) durch je ein V-förmiges Röhrenbündel (c, c') unmittelbar verbunden ist, so daß die zwischen dem mittleren und den beiden äußeren Oberkesseln stattfindenden, dem mittleren Oberkessel in gleicher Strömungsrichtung zugeführten Wasserumläufe durch keine Unterkessel unterbrochen sind, vielmehr in dauernd gleichem Querschnitt durch die ununterbrochenen V-förmigen Röhrenbündel erfolgen. PATENT CLAIM: Steam generator with three adjacent upper boilers, which are connected to one another by tube bundles, characterized in that the middle upper boiler (h) is directly connected to the two outer upper boilers (a, c) by a V-shaped tube bundle (c, c ') each is, so that the water circulations between the middle and the two outer upper kettles and fed to the middle upper kettle in the same direction of flow are not interrupted by any lower kettles, but rather take place in continuously the same cross-section through the uninterrupted V-shaped tube bundle.
