Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bildet eine Ausführungsform des durch Patent 179455 geschützten Dampfkessels, dessen wesentlichstes Merkmal darin besteht, daß der Dampfsammler dachförmig gestaltet ist und an seinen Schenkelenden mit Vorwärmern in Verbindung steht, die eine solche Höhenlage haben, daß der Wasserspiegel in ihnen gleiche Höhe mit dem Wasserspiegel im Dampfsammler hat, dessen Wasserinhalt im Vergleich mit dem der Vorwärmer gering ist. In diesem Patent ist zugleich die Anordnung von Fallröhren dargestellt, die unmittelbar an die unteren Schenkelteile des dachförmigen Dampfsammlers angeschlossen sind. Um nun den Umlauf im Kessel noch zu verbessern und den Wirkungsgrad des Kessels zu erhöhen, sind bei der neuen Ausführungsform des Kessels die Fallröhren an die Vorwärmer angeschlossen; außerdem ist dafür gesorgt, daß das Wasser in den Vorwärmern sich mit dem im Dampfsammler befindlichen Wasser nicht sofort vermischen kann.The invention forms an embodiment of the steam boiler protected by patent 179455, the most important feature of which is that the steam collector is designed in the shape of a roof and with its leg ends Preheaters is connected, which have such an altitude that the water level in them has the same height as the water level in the steam collector, its water content in comparison with that of the preheater is low. This patent also shows the arrangement of downspouts, which are directly attached to the lower leg parts of the roof-shaped steam collector are connected. In order to improve the circulation in the boiler and the Increasing the efficiency of the boiler are the new design of the boiler the downpipes connected to the preheaters; it is also ensured that the water in the preheaters does not match the water in the steam collector can mix immediately.

Auf der Zeichnung ist der neue Kessel im senkrechten Querschnitt dargestellt. Mit d ist wieder der dachförmige Dampfsammler bezeichnet, mit g sind die Vorwärmer, mit a die sich kreuzenden Röhrenbündel und mit c die Schlammsammler bezeichnet. Die FaIlröhren V verbinden bei der neuen Ausführungsform die Schlammsammler mit den Vorwärmern g anstatt unmittelbar mit den unteren Schenkelenden der Dampfkammer d. Ferner ist in den Vorwärmern eine schräge Platte h angebracht, die nur einen schmalen Durchlaß dem über ihr zugeführten Speisewasser gewährt.The drawing shows the new boiler in a vertical cross-section. With d the roof-shaped steam collector is again designated, with g the preheaters, with a the intersecting tube bundles and with c the sludge collectors. In the new embodiment, the fall pipes V connect the sludge collectors to the preheaters g instead of directly to the lower leg ends of the steam chamber d. Furthermore, an inclined plate h is attached in the preheaters, which allows only a narrow passage for the feed water supplied via it.

Es ist ersichtlich, daß ein freier Umlauf des Kessel wassers stattfinden kann, welches durch die Fallröhren V und die Schlammsammler c zu den Steigröhren α gelangt und aus dem Dampfsammler d durch die schrägen Rohre πι in die Vorwärmer g zurückgeht. Der Zufluß des Speisewassers zu den Röhren b' geht nur allmählich nach Maßgabe der. Verdampfung vor sich.It can be seen that free circulation of the boiler water can take place, which passes through the downpipes V and the sludge collector c to the riser pipes α and returns from the steam collector d through the inclined pipes πι in the preheater g . The inflow of the feed water to the tubes b ' is only gradual in accordance with the. Evaporation in front of you.
