Description

Als Rückstrahlfläche wirkende Decke der unteren Erweiterung eines schachtförmigen Feuerraumes Bei den meisten schachtförmigen Feuer= räumen von Dampferzeugern, insbesündere bei Rostfeuerungen, ist der Feuerraum unten erweitert. Die Deckenflächen dieser Erweiterungen dienen meistens als Rückstrahlfläch:e für die Feuerung. Sie- werden zum größten Teil als Hängedecke ausgeführt; deren Anhau nicht nur kostspielig und schwer, sondern deren Steinhalterungen bei beschädigten und abgebrannten Steinen ,auch leicht durch Wärmeeinstrahlung zerstört werden. Zwar war es bekannt, die Steine der Decke durch wassergekühlte Rohre zu halten. Hierbei erfolgt die 'Zuführung des Kühlmittels von einem am unteren Ende der Rohre liegenden Verteiler aus. Dadurch sind die Rohre nur wenig nachgiebig und können sich bei Wärmeeinwirkung nur in Richtung der Längsachse der Rohre ausdehnen. Ebenso können sich Wärmespannungen in den Steinen nur in dieser Richtung ausgleichen, während in Querrichtung zu den Rohren die Decke starr gehaltert ist. Außerdem hat die Anordnung eines Verteilers am unteren Ende der Rohre den Nachteil, daß :eine Behinderung durch die Feuerungseinrichtung :erfolgt.Ceiling of the lower extension of one that acts as a reflective surface shaft-shaped combustion chamber With most shaft-shaped fireplaces of steam generators, especially with grate firing, the firebox is expanded below. The ceiling surfaces These extensions mostly serve as a reflecting surface for the furnace. She- are for the most part designed as suspended ceilings; Putting them on is not only expensive and heavy, but their stone holders for damaged and burnt stones can easily be destroyed by heat radiation. Although it was known the stones the ceiling by water-cooled pipes. The 'feeding of the Coolant from a manifold located at the bottom of the tubes. Through this the pipes are only slightly flexible and can only move in the direction of the action of heat along the longitudinal axis of the pipes. Thermal stresses can also build up in the stones only equalize in this direction, while in the transverse direction to the pipes the ceiling is rigidly held. In addition, the arrangement has a distributor at the lower end the pipes have the disadvantage that: an obstruction by the furnace: occurs.

Erfindungsgemäß wird nun vorgeschlagen, die Steine der als Rückstrahlfläche wirkenden Decke der unteren Erweiterung eines schachtförmigen Feuerraumes durch von den Feuerraumwänden herabgezogene und über die Decke verlaufende gekühlte Rohre derart zu haltern, daß die Rohre am Ende der Decke umgebogen und wieder an :der Feuerraumwand hachgezogen sind. An sich sind Rohrführungen an Feuerraumwänden bekannt, bei denen die auf- und absteigenden Rohre durch Schleifen miteinander verbunden sind. Durch die Anwendung :dieser Schl.eifenbildung können die Kühlrohre außerordentlich elastisch gelagert werden, so daß die gehalterten Stein, die beispielsweise durch Stichflammen sehr unterschiedlich beheizt sein können, sich nicht nur in Längsrichtung der Halterohre, sondern auch in der Querrichtung auszudehnen vermögen. Durch die Umkehrung der Rohre am Ende der Decke werden Sammler und Verteiler -gerade an einer Stelle vermieden. wo sie insbesondere die Fetteruingsei;n.r:cl)-tungen stören würden. Bei der vorgeschlagenen Ausführung ist es auch möglich, jeden gewünschten Grad der Kühlung zum Schutze der Rückstrahlflächen zu erzielen. da man es in der Hand hat, die Halterohre in beliebiger Anzahl vor und hinter den Rückstrahlflächen zu verlegen.According to the invention it is now proposed to use the stones as a reflecting surface acting ceiling of the lower extension of a shaft-shaped combustion chamber Cooled pipes drawn down from the furnace walls and running over the ceiling to be held in such a way that the pipes are bent over at the end of the ceiling and back on: the The combustion chamber wall are pulled up. Pipe guides on combustion chamber walls are known per se, where the ascending and descending pipes are connected to one another by loops are. By using: this loop formation, the cooling tubes can do extraordinary things be elastically mounted, so that the held stone, for example by Jet flames can be heated very differently, not only in the longitudinal direction the holding tubes, but rather are also able to expand in the transverse direction. By reversing the pipes at the end of the ceiling, collectors and distributors are straight avoided at one point. where they especially the Fetteruingsei; n.r: cl) -tungen would disturb. In the proposed design, it is also possible to create any desired To achieve the degree of cooling to protect the reflective surfaces. since you can find it in the Hand, any number of holding tubes in front of and behind the reflective surfaces relocate.

Die Erfindung ist durch die Abb. i bis i i näher erläutert.The invention is explained in more detail by FIGS. I to i i.

Die Ab-b. i zeigt die Anordnung am Zündgewölbe, z. B. einer Wanderrostfe.uerung. Am Rostbett i wird die hohle eingefahren. Das Rohr 2 zieht sich an der Vorderwand des Feuerraumes herab und verläuft vor d,rii Steinen 3, die das Zündgewölbe bilden, "v01),-i die Steine 3 an den Rohren 2 befestigt sind. Das Rohr wird dann in diesem Fall hinter den Steinen wieder zurückgeführt und steigt an -der senkrechten Wand wieder hoch.The ab-b. i shows the arrangement on the ignition vault, e.g. B. a traveling grate. The hollow is retracted on the grate bed i. The tube 2 pulls itself on the front wall of the firebox and runs in front of d, rii stones 3, which form the ignition vault, "v01), - i the stones 3 are attached to the pipes 2. The pipe is then in this Fall is led back behind the stones and climbs up the vertical wall high again.

Die Abb. 2 bis .i zeigen, daß es auch leicht möglich ist, jeden beliebigen Grad der Kühlwirkung einzuhalten, je nachdem., wieviel Rohre man vor den Steinen entlang zieht; wie aus den Abb. 5 und 6 hervorgeht, liegen bei geringer Kühlwirkung beide Schenkel eilniger herabhängender Rohre hinter den Steinen.A Fig. 2 to .i show that it is also readily possible any degree of K ühlwirkung observed, depending on how much pulling pipes before the stones along. As can be seen from Figs. 5 and 6, when the cooling effect is low, both legs of the hanging pipes are behind the stones.

Die Abb. ; bis i o -neigen derartige Ausbildungen der die Steine tragenden Rohre, daß ein leichtes Herausnehmen und Wi,c,dcreinsetzen möglich ist. Bei der Ausführung nach den Abb. 7 und S wird das von der senkrechten Wand herabkommende Rohr so zurückgebogen, daß beide Schenkel vor den Steinen liegen und die Steine von oben leicht eingelegt werden können. Zur Halterung des Rohres wird dieses am Anfang des Gewölbes mit einer Schleife 4. nach oben geführt und an einem Träger angehängt. Bei. der Ausbildung nach den Abb.9 und io sind die tragenden Rohre 2 so abgebogen, daß ein Einschieben der Steine 3 in Richtung des Rohrverlaufs möglich ist.The fig; to i o tend to have such designs of those carrying the stones Tubes that can be easily removed and reinserted. In the Execution according to Fig. 7 and S is the one coming down from the vertical wall Tube bent back so that both legs are in front of the stones and the stones can be easily inserted from above. To hold the pipe this is on Beginning of the vault with a loop 4. upwards and attached to a support attached. At. the design according to Figures 9 and 10 are the supporting pipes 2 bent so that an insertion of the stones 3 in the direction of the pipe is possible is.

Die Abb. t i zeigt noch die Ausführung eines weit über einen Rost reicbenden Ausbrandgewölbes z. B. für einen Stoker.Fig. T i still shows the execution of a well over a grate ricbenden burn-out vault z. B. for a stoker.
