Description
Röhrendampfkessel mit quer zum Gasweg angeordneter Obertrommel und mehreren im Heizgasstrom nebeneinander angeordneten selbständigen Wasserumläufen mit eigener Speisung Die Erfindung bezieht sich auf eine- besondere Ausgestaltung von Röhrendampfkesseln mit quer zum Gasstrom angeordneter Obertrommel und hat zum Zweck, den Wasserstand in dieser auch bei verschieden starker Beheizung der Heizrohre gleichmäßig einstellen -zu können.Tubular steam boiler with upper drum arranged transversely to the gas path and several independent water circulations arranged next to one another in the heating gas flow with its own supply The invention relates to a special embodiment of tubular steam boilers with an upper drum arranged transversely to the gas flow and has to Purpose, the water level in this even with different degrees of heating of the heating pipes to be able to adjust evenly.
Man kennt zwar schon Röhrendampfkessel, die mehrere im Heizgasstrom nebeneinander angeordnete selbstständige Wasserumläufe mit eigener Speisung besitzen und bei denen Quertrennwände in die Obertrommel eingesetzt sind. Bei dieser Bauart kann jedoch durch die Querwände keine Trennung der einzelnen Wasserumläufe bewirkt werden, was schon daraus hervorgeht, daß die Trennwände zwischen den zugehörigen Verdampfungsröhren angeordnet sind und nicht bis zum Wasserspiegel in der Obertrommel reichen.Tubular steam boilers are already known with several in the heating gas flow Have independent water circuits arranged next to one another with their own feed and where transverse partitions are inserted into the upper drum. With this type of construction However, the transverse walls cannot separate the individual water circuits become, which is evident from the fact that the partitions between the associated Evaporation tubes are arranged and not up to the water level in the upper drum are sufficient.
Wenn nun ein solcher Kessel ungleich beheizt wird, wie dies besonders bei sehr langer Obertrommel sehr leicht eintritt, so kann man erfahrungsgemäß nicht erreichen, daß der Wasserstand in allen Teilen der Obertrommel gleich hoch ist. Es hat nämlich trotz der Trennwände das Wasser die Möglichkeit, von einem Ende der Obertrommel nach dem anderen hinüberzulaufen, so daß sich auf der stärker beheizten Seite ein höherer Wasserstand einstellt als auf der schwächer beheizten Seite. Ein derartiger Kessel ist also bei ungleicher Beheizung nicht mehr voll betriebssicher.If such a boiler is heated unevenly, like this in particular If the top drum is very long it occurs very easily, experience has shown that this is not possible achieve that the water level in all parts of the upper drum is the same. In spite of the partitions, the water has the possibility of coming from one end of the Overhead drum after the other to run over, so that on the more heated Side sets a higher water level than on the less heated side. A Such a boiler is therefore no longer fully operationally reliable if the heating is unequal.
Dieser Übelstand wird nun gemäß der vorliegenden Erfindung dadurch vermieden, daß die Obertrommel durch über den Wasserspiegel reichende Scheidewände in mehrere den Wasserumläufen entsprechende Abteilungen unterteilt ist. Der Wasserstand in jeder Abteilung ist nunmehr gänzlich unabhängig von demjenigen in den anderen Abteilungen und wird durch je einen besonderen Speiseregler auf der vorgeschriebenen Höhe gehalten, so daß ein durchaus betriebssicheres Arbeiten der Kesselanlage verbürgt ist. Die Trennwände brauchen nicht sehr stark gebaut zu werden, da sie keine wesentlichen Beanspruchungen auszuhalten haben. Es ist also nunmehr durch die vorliegende Erfindung möglich, Kessel mit querliegender Obertrommel sehr breit zubauen, wie dies häufig durch die besondere Art der Feuerung, z. B. Braunkohlenfeuerung, verlangt wird.This drawback is now made in accordance with the present invention avoided that the upper drum through partition walls reaching above the water level is divided into several departments corresponding to the water circulation. The water level in each department is now completely independent of that in the others Departments and is prescribed by a special feed regulator on each Maintained height, so that the boiler system works safely and reliably is. The partitions do not need to be built very strong as they are not essential Have to endure stress. So it is now through the present invention It is possible to build a very wide boiler with a transverse top drum, as is often the case due to the special type of firing, e.g. B. lignite firing is required.
In der Zeichnung ist die Erfindung beispielsweise veranschaulicht.The invention is illustrated by way of example in the drawing.
