Description
Steilrohrkesselanlage für große Heizflächen Steilrohrkessel lassen sich, um große Heizflächen zu gewinnen, günstig so aufstellen, daß die Wasser- und Dampftrommeln quer zur Richtung des Feuerraumes liegen. Man verwendet in diesem Falle also zwei getrennte Kesselteile mit je zwei Ober- und zwei Untertrommeln, die durch Rohrbündel miteinander verbunden sind, wodurch es möglich ist, dem Rost oder dem Feuerraum gegenüber je ein Rohrbündel jedes Teiles anzuordnen, also mit zwei Rohrbündeln die strahlende Wärme aufzunehmen. Auch die Verteilung der Rauchgase, die in großen Mengen bei großen Heizflächen anfallen, ist eine günstige, da sie in zwei Teilen abgeführt werden.Vertical tube boiler system for large heating surfaces In order to gain large heating surfaces, set up favorably so that the water and The steam drums are positioned at right angles to the direction of the combustion chamber. One used in this So there are two separate boiler parts with two upper and two lower drums each, which are connected by tube bundles, which makes it possible to use the grate or to arrange a tube bundle of each part opposite the furnace, i.e. with two tube bundles to absorb the radiant heat. The distribution of the smoke gases, which occur in large quantities with large heating surfaces, is a favorable one because it be discharged in two parts.
Vereinigt man in. dieser Weise zwei normale Steilrohrkessel miteinander, so liegen die beiden die strahlende Wärme aufnehmenden Rohrbündel derart, daß oben zwischen den beiden Obertrommeln beider Teile die strahlende Wärme teilweise durch Mauerwerk aufgefangen werden muß. Die Nachteile, die in dieser Notwendigkeit zu erblicken sind, liegen klar auf der Hand, da das Mauerwerk sehr hohen Temperaturen ausgesetzt ist und sehr bald zerfällt, wodurch die Betriebssicherhept des IZessiels empfindlich gestört wird.If you combine two normal vertical tube boilers in this way, so are the two tube bundles absorbing the radiant heat in such a way that at the top the radiating warmth partially penetrates between the two upper drums of both parts Masonry must be caught. The disadvantages involved in this need too Behold, are obvious because the masonry is very hot is exposed and very soon disintegrates, which makes the operational safety of the target is sensitively disturbed.
Der Zweck der Erfindung ist es nun, diese Nachteile zu beseitigen, und zwar geschieht dies dadurch, daß die dem Feuerraum zunächst gelegene Ober- und Untertrommel des einen Teiles mit der entsprechenden Unter-und Obertrommel des anderen Teiles durch weitere, zur Heizflamme bin liegende, sich kreu= zende Verdampfungsrohre verbunden . sind. Auf diese Weise wird eine wassergekühlte Abschlußwand nach der Kesseldecke zu gebil. det, die einmal die unmxtrelbare strahlenide Wärme aufnimmt, das andere Mal die Feuergase nach beiden Seiten abdrängt, so daß diese die Rohrbündel beider Teile ausgiebiger bestreichen. Abgesehen hiervon. wird vermittels der Verbindungsrohre ein 'kräftiger Wasserumlauf zwischen beiden Kesselteilen hervorgerufen, die an sich ja nur in Höhe der Obertrommeln miteinander in Verbindung stehen. Auf diese Weise wird der Wasserstand in beiden Einzelteilen stets ausgeglichen, und es werden so Gefahren beseitigt, die bei Unregelmäßigkeit in der Speisung bzw. bei ungleichmäßiger Verdampfung auftreten könnten.The purpose of the invention is now to eliminate these disadvantages, and this is done by the fact that the top and first located in the furnace Lower drum of one part with the corresponding lower and upper drum of the other Part by further, to the heating flame bin lying, intersecting evaporation pipes tied together . are. In this way, a water-cooled end wall after the Boiler roof to be formed. det that once absorbs the immeasurable radiant heat, the other time pushes the fire gases away to both sides, so that these the tube bundle Brush both parts more extensively. Apart from that. is made by means of the connecting pipes a 'vigorous water circulation between the two boiler parts caused, which in itself yes, they are only connected to each other at the height of the top drums. In this way the water level in both parts will always be equalized, and it will be so The dangers associated with irregularities in the supply or with irregular Evaporation could occur.
Auf der Zeichnung ist ein Ausführungsbei.-spiel des Erfindungsgegenstandes in senkrechtem Schnitt dargestellt.The drawing shows an exemplary embodiment of the subject matter of the invention shown in vertical section.
Die beiden Kesselteile bestehen aus je -zwei Obertrommeln 1, 2, 3, 4. und aus je zwei Untertrommeln 5, 6, 7 und B. Die Trommeln i und 5 stehen durch ein Rohrbündel 9, die Trommeln 2 und 6 durch eire Rohrbündel i o, die Trommeln 3 und 7 durch ein Rohrbündel i i und die Trommeln q. und 8 durch ein Rohrbündel i-- miteinander in Verbindung, während die vier Obertrommeln 3, 1, 2 und q durch Leitungen 13, 14 und 15 miteinander verbunden sind. Zwischen den Rohrbündeln 9 und ii bzw. io und 12 sind überhitzer 16 angeordnet. Zugscheidewände 17 lassen die aus dem Feuerungsraum 18 kommenden: Heizgase sowie, durch Pfeile angedeutet, die einzelnen Rohrbündel durchstreichen, um nach den Rauchgasabzugkanälen i 9 zu gelangen.The two boiler parts each consist of two upper drums 1, 2, 3, 4. and from two lower drums 5, 6, 7 and B. The drums i and 5 stand through a tube bundle 9, the drums 2 and 6 through a tube bundle i o, the drums 3 and 7 through a tube bundle i i and the drums q. and 8 through a tube bundle i-- in connection with each other, while the four upper drums 3, 1, 2 and q are connected by lines 13, 14 and 15 are connected to each other. Between the tube bundles 9 and ii or 10 and 12 superheaters 16 are arranged. The partition walls 17 let them out of the furnace 18 coming: heating gases and, indicated by arrows, the individual tube bundles Cross out to get to the smoke exhaust ducts i 9.
Außer den angegebenen Verbindungen führen von der Obertrommel i mach der Untertrommel 6 Rohre 2o und von der Obertrommel 2 nach der Untertrommel 5 Rohre 2 i, die sich bei 22 kreuzen und auf diese Weise eine wassergekühlte Abschlußwand nach oben bilden. Der Kreuzungspunkt 22 kann, wie bei 22' angedeutet, durch geeignete Biegung der Rohre 2o'. und 21' wesentlich tiefer gelegt werden, um auf diese Weise die Heizgase seitlich nach den unteren Teilen der Rohrbündel 9 und io abzulenken.In addition to the specified connections lead from the upper drum i mach the lower drum 6 tubes 2o and from the upper drum 2 to the lower drum 5 tubes 2 i, which cross at 22 and in this way a water-cooled end wall form upwards. The intersection point 22 can, as indicated at 22 ', by suitable Bend of the tubes 2o '. and 21 'are placed much deeper in this way divert the heating gases laterally to the lower parts of the tube bundle 9 and io.
An Stelle einer ReiheRohre2o und 21 können natürlich auch mehrere derartige Reihen vorgesehen sein, wodurch der wassergekühlte Abschluß noch wirkungsvoller wird. Auch der Wasserumlauf durch beide Kesselteile erfährt dann selbstverständlich -eine Verstärkung.Instead of a row of tubes 21 and 21, several can of course also be used such rows can be provided, making the water-cooled closure even more effective will. Of course, the water circulation through both boiler parts is then also experienced -a reinforcement.
