Description

Innengefeuerter Strahlungsdampfkessel Das Hauptpatent betrifft einen innengefeuerten Strahlungsdampfkessel für flüssige, gas- oder staubförmige Brennstoffe, dessen Feuerraumwände aus Gruppen von nebeneinander zwischen oberen und unteren Sammelkasten senkrecht verlaufenden Rohren bestehen, wobei die Rohrgruppen symmetrisch rings um einen senkrecht durch die Mitte des Feuerraumes verlaufenden und gegen die Strahlungswärme geschützten Fallweg für das Wasser liegen.Internally Fired Radiant Steam Boiler The main patent relates to one internally fired radiant steam boiler for liquid, gaseous or dusty fuels, whose firebox walls consist of groups of side by side between upper and lower Collecting box consist of vertically extending pipes, the pipe groups being symmetrical all around a perpendicular through the middle of the furnace and against the radiant heat protected fall path for the water.

Durch die Erfindung soll diese Kesselbauart verbessert werden, indem eine zusätzliche Heizfläche symmetrisch dicht um den senkrecht durch die Mitte des Feuerraumes verlaufenden Fallweg zu dessen Schutz gegen die Strahlungswärme angeordnet wird.The invention is intended to improve this type of boiler by an additional heating surface symmetrically close to the one perpendicular through the center of the Firebox extending fall path arranged to protect it against the radiant heat will.

Durch die zusätzliche Heizfläche wird die nach innen strahlende Wärme noch zur Dampferzeugung mit herangezogen. Außerdem kann das bisher bei diesen Kesseln zum Schutze des Fallweges nötige Mauerwerk, das von der Strahlungswärme sehr stark beansprucht wird und daher zu vielen Störungen Anlaß geben kann, in Wegfall kommen.The inward radiating heat is generated by the additional heating surface still used for steam generation. In addition, this can so far with these boilers Masonry necessary to protect the fall path, which is very strong from the radiant heat is claimed and can therefore give rise to many disturbances, come to an end.

Die Anordnung kann so getroffen werden, daß das Fallrohr in an sich bekannter Weise von einem konzentrischen Rohr umgeben ist, wobei in dem Raum zwischen den beiden Rohren eine Aufwärtsbewegung des Wassers stattfindet. Eine andere zweckmäßige Anordnung besteht darin, daß, wie bei anderen Kesseln bereits bekannt, eine größere Anzahl von wassergekühlten Rohren um das Fallrohr herum angeordnet wird, so daß sie eine Bestrahlung des Fallrohres verhindern.The arrangement can be made so that the downpipe in itself known way is surrounded by a concentric tube, in the space between an upward movement of the water takes place in the two pipes. Another functional one Arrangement is that, as with other boilers already known, a larger one Number of water-cooled pipes is arranged around the downpipe, so that they prevent irradiation of the downpipe.

Die Zeichnung zeigt zwei verschiedene Ausführungsbeispiele der Erfindung.The drawing shows two different exemplary embodiments of the invention.

In Abb. i sind die Wände des Verbrennungsraumes durch Rohre i gebildet, deren obere und untere Enden in Sammelkasten 2 eingewalzt sind. Diese Kasten sind durch obere und untere Verbindungsrohre 3 mit einer Trommel 9 und i i verbunden. Der Dampfkessel ist von einem wärmeisolierenden Gehäuse 6 umgeben. Ein Kanal 7 leitet die Verbrennungsgase zu etwa noch vorgesehenen zusätzlichen Heizflächen, wie Vorwärmern, Dampfüberhitzern oder Lufterhitzern. Im oberen Teil des Verbrennungsraumes sind Brenner 8 angeordnet. Die Behälter 9 und ii stehen durch das Fallrohr io in Verbindung, durch welches das Wasser aus dem oberen in den unteren Behälter gelangt. Der untere Behälter i i ist durch feuerfestes Mauerwerk o. dgl. 5 geschützt. Das Fallrohr io ist erfindungsgemäß von einem zweiten Rohr 12 umgeben, welches in gleicher Weise zum Verdampfen verwendet wird wie die Rohre i. Außerdem dient es als Kühlrohr für das Fallrohr in, so daß der Schutz des letzteren durch besonderes Mauerwerk entbehrlich ist.In Fig. I the walls of the combustion chamber are formed by pipes i, the upper and lower ends of which are rolled into the collecting box 2. These boxes are connected to a drum 9 and i i by upper and lower connecting pipes 3. The steam boiler is surrounded by a heat-insulating housing 6. A channel 7 conducts the combustion gases to any additional heating surfaces that may be provided, such as preheaters, Steam superheaters or air heaters. In the upper part of the combustion chamber are Burner 8 arranged. The containers 9 and ii are connected by the downpipe io, through which the water passes from the upper to the lower container. The lower Container i i is protected by fireproof masonry or the like 5. The downpipe io is surrounded according to the invention by a second tube 12, which in the same way is used for evaporation like the tubes i. It also serves as a cooling pipe for the downpipe in, so that the protection of the latter by special masonry can be dispensed with is.

Bei der Ausführungsform nach Abb. 2 ist das Fallrohr io durch eine größere Anzahl von Rohren 1.3 umgeben, die das Fallrohr gegen die im Verbrennungsraum herrschende Strahlungswärme schützen. Diese Anordnung wird besonders bei größeren Einheiten empfehlenswert sein.In the embodiment of Fig. 2, the downpipe is io by a A larger number of pipes 1.3 surround the downpipe against the one in the combustion chamber protect the prevailing radiant heat. This arrangement is especially useful for larger ones Units to be recommended.
