KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist ein Dampferzeuger mit Wasserröhren zwischen einem Unter- und einem Oberkessel und einer senkrechten Wand zwischen den Röhren zur Führung der Heizgase. Das Wesen der Erfindung besteht darin, daß diese Führungswand zugleich zur Aufnähme von Wasserrücklauf rohreri, die in bekannter Weise vom Oberkessel zum Unterkessel führen, ausgenutzt ist,The invention relates to a steam generator with water pipes between one Lower and upper kettle and a vertical wall between the pipes for guidance of the heating gases. The essence of the invention is that this guide wall at the same time for taking up water return pipes, which lead in a known manner from the upper boiler to the lower boiler is used,
ίο um sie vor dem unmittelbaren Anprall der Heizgase zu schützen. Hierdurch ergibt sich gegenüber bekannten Kesseln mit Rücklaufrohren, welche dem unmittelbaren Aufprall der Feuerungsgase ausgesetzt sind, der Vorteil, daß der Wasserumlauf nicht gestört wird, da das Wasser in den Rücklaufrohren nicht derart erwärmt wird, daß es entgegen der gewünschten, nach abwärts gerichteten Bewegung nach oben strömen könnte. Da jedoch der obere Teil der Rücklaufrohre für den Durchtritt der Feuergase von der Abdeckung frei bleibt, so wird das Wasser an dieser Stelle nahezu bis auf ioo° erhitzt, also auf eine Temperatur, bei der die Ausfällung der Kesselsteinbildner eintritt. Diese sinken dann in den Rücklaufrohren in den Unterkessel, während die engen Röhren von Kesselsteinablagerungen verschont bleiben.ίο to them from the immediate impact of the Protect hot gases. This results in comparison to known boilers with return pipes, which are exposed to the direct impact of the combustion gases, the advantage, that the water circulation is not disturbed because the water in the return pipes is not so is heated so that it is contrary to the desired, downward movement after could flow above. However, since the upper part of the return pipes for the passage of the Fire gases remain free from the cover, so the water at this point is nearly up heated to 100 °, that is, to a temperature at which the precipitation of the scale-forming agents entry. These then sink in the return pipes into the lower boiler, while the narrow ones Tubes are spared from scale deposits.
Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt.An embodiment of the invention is shown in the drawing.
α ist die Einschüttöffnung für das Feuerungsmaterial, b ist der Unterkessel, welcher mit dem Oberkessel c in bekannter Weise durch gekrümmte Röhren d verbunden . ist. α is the pouring opening for the firing material, b is the lower boiler, which is connected to the upper boiler c in a known manner by curved tubes d . is.
Bei e ist eine Vorlage angedeutet, die ebenfalls durch Röhren f mit dem Oberkes'sel c in Verbindung steht. Der Oberkessel ist ferner in bekannter Weise mit dem Unterkessel durch weite Wasserrücklaufrohre g verbunden. Diese Rohre sind, gemäß der Erfindung, auf dem größten Teil ihrer Länge von der Wand h aufgenommen, welche, nebst einer zweiten Wand i außerhalb der Röhre d, die Feuergase auf dem durch die Pfeile angegebenen Wege führen soll.At e a template is indicated, which is also connected to the Oberkes'sel c through tubes f. The upper boiler is also connected in a known manner to the lower boiler by wide water return pipes g. According to the invention, these pipes are received over the greater part of their length by the wall h which, together with a second wall i outside the pipe d, is intended to guide the fire gases on the path indicated by the arrows.
Der Betriebsvorgang des neuen Dampferzeugers ist folgender: Das Wasser in den Röhren d, welche den heißen Feuergasen unmittelbar ausgesetzt sind, steigt mit dem aus ihm gebildeten Dampf in den Oberkessel c auf. Da nun die Erwärmung des Wassers in den Rücklauf rohren g wegen der teil weisen Ummantelung durch die Wand h nur eine geringere sein kann, so sinkt das nicht verdampfte Wasser des Oberkessels durch diese Rohre mit niedrigerer Temperatur in bekannter Weise in den Unterkessel zurück, um von hier aus zur Verdampfung zu gelangen.The operating procedure of the new steam generator is as follows: The water in the pipes d, which are directly exposed to the hot fire gases, rises with the steam formed from it into the upper boiler c. Since the heating of the water in the return pipes g can only be lower because of the partial sheathing through the wall h , the non-evaporated water from the upper boiler sinks back through these pipes at a lower temperature in a known manner to the lower boiler here to get out of the evaporation.
Es ist nicht unbedingt erforderlich, die Rücklaufrohre g an beiden Seiten zu ummanteln, es würde auch genügen, sie nur an einer Seite, z. B. der linken Seite, mit der Wand h zu bedecken, denn auch hierdurch werden sie der Wirkung der Feuergase mehr oder weniger entzogen. Gegebenenfalls können anstatt der Rohre g kammerartige Ausbildungen vorgesehen sein.It is not absolutely necessary to coat the return pipes g on both sides; it would also suffice to only cover them on one side, e.g. B. the left side to cover with the wall h , because this also removes them from the action of the fire gases to a greater or lesser extent. If necessary, chamber-like configurations can be provided instead of the tubes.
