Description
Flammrohrkessel mit Wasserumlaufrohren Die Erfindung betrifft einen Flammrohrkessel. Es ist bekannt, den unteren Teil des Kesselwasserraumes mit dem oberen durch Wasserumlaufrohre zu verbinden. Die Verbindung geschah entweder mit radial verlaufenden Rohren oder aber mit zum Teil in Längsrichtung oder schräg zu ihr verlaufenden Rohren, gegebenenfalls auch mit solchen, die S-förmig gebogen waren und infolgedessen trotz des Längsverlaufs radial in die Flammrohrwandung einmünden und bei mehreren in der Längsrichtung des Flammrohres hintereinanderlagen.Flame tube boiler with water circulation pipes The invention relates to a Flame tube boiler. It is known that the lower part of the boiler water space with the connect upper by water circulation pipes. The connection happened with either radially extending tubes or with some in the longitudinal direction or at an angle their running pipes, possibly also with those that were bent into an S-shape and consequently open radially into the flame tube wall despite the longitudinal course and if there are more than one in the longitudinal direction of the flame tube.
Bei radialen Rohren war es außerdem bekannt, die Rohre im gleichen Drehsinne gegeneinander zu versetzen, um so einen Drall in der Strömung der Feuergase zu erreichen.In the case of radial tubes, it was also known to use the tubes in the same way To offset the senses of rotation against each other to create a twist in the flow of the fire gases to reach.
Der Erfindung gemäß sind nun schwache, etwa S-förmig gebogene und mit dem wesentlichen Teil ihrer Länge in Längsrichtung des Flammrohres verlaufende Rohre im gleichen Drehsinne und in Längsrichtung gegeneinander versetzt, so daß eine Drallführung gebildet wird, die aber im wesentlichen durch den längs verlaufenden Teil der Rohre begrenzt wird. Dadurch wird ein allseitig im wesentlichen stauungsfreies Umstreichen der Umlaufrohre durch die Feuergase erzielt, so daß auch hierdurch eine Verbesserung der Heizwirkung neben der an sich bekannten durch die Drallwirkung und die damit erreichte Verlängerung des Weges der Feuergase erreichtenErhöhungderHeizwirkungerreichtwird.According to the invention are now weak, approximately S-shaped and bent running with the substantial part of its length in the longitudinal direction of the flame tube Pipes offset from one another in the same direction of rotation and in the longitudinal direction, so that a swirl guide is formed, but which is essentially through the longitudinal Part of the pipes is limited. As a result, it is essentially free of congestion on all sides Stroking the circulation pipes achieved by the fire gases, so that this also a Improvement of the heating effect in addition to what is known per se due to the swirl effect and the increase in the heating effect achieved thereby is achieved.
Weiter wird der durch die S-Form und die Anwendung dünner Rohre gegebene Vorteil aufrechterhalten, der darin besteht, daß infolge der Nachgiebigkeit dieser Rohre ihre Dehnungen durch die Temperaturunterschiede nicht wesentlich auf die Flammrohrwandungen übertragen werden, so daß u. a. das Auftreten von Undichtigkeiten vermieden wird.It is also given by the S-shape and the use of thin tubes Maintaining advantage, which is that due to the resilience of this Pipes do not have their expansion due to the temperature differences significantly on the flame tube walls are transmitted, so that i.a. the occurrence of leaks is avoided.
Diese bezüglich der Wärmeübertragung und der mechanischen und Wärmebeanspruchungen günstige Drallführung kann im übrigen bei der der Erfindung entsprechenden Ausführung mit gleichen Bauteilen, also außerordentlich billig, hergestellt werden. Auf der Zeichnung ist beispielsweise eine Ausführungsform des Erfindungsgegenstandes dargestellt.These with regard to heat transfer and mechanical and thermal stresses In addition, favorable swirl guidance can be used in the embodiment corresponding to the invention be made with the same components, so extremely cheap. On the The drawing shows, for example, an embodiment of the subject matter of the invention.
Fig. i zeigt einen Längsschnitt durch einen der Erfindung entsprechend ausgebildeten Flammrohrkessel, Fig. 2 einen Querschnitt durch denselben gemäß II-II in Fig. i.Fig. I shows a longitudinal section through one of the invention formed flame tube boiler, FIG. 2 shows a cross section through the same according to II-II in Fig. i.
Innerhalb des Flammrohres a sind S-förmig gebogene Umlaufrohre b angeordnet, und zwar so, daß sie radial in die Flammrohrwandung einmünden.S-shaped curved circulation pipes b are arranged within the flame pipe a, in such a way that they open radially into the flame tube wall.
Alle diese Rohre b verlaufen in Längsschnittebenen des Flammrohres. Diese Längsschnittebenen sind.aber für jedes folgende Rohr um einen gewissen Winkel verdreht. Außerdem sind die Rohre in bezug aufeinander in Längsrichtung verschoben.All of these tubes b run in longitudinal sectional planes of the flame tube. These longitudinal sectional planes are, however, at a certain angle for each subsequent pipe twisted. In addition, the tubes are displaced in the longitudinal direction with respect to one another.
Die Rohrgruppe führt daher die Feuergase schraubenförmig, wobei dann die Gase im wesentlichen die Rohre in Längsrichtung bestreichen, an den Rohren also verhältnismäßig wenig Widerstand finden und wenig Wirbel bilden.The pipe group therefore leads the fire gases helically, with then the gases essentially sweep the pipes in the longitudinal direction, i.e. on the pipes find relatively little resistance and form little eddies.
Die Rohre verbinden den unteren Teil des Wasserräumes des Kessels c mit dem oberen Teil des Wasserraumes und leiten unter Einwirkung der infolge der besonderen Ausführung besonders hohen Erwärmung, die ihnen von den Feuergasen erteilt wird, das Wasser vom unteren, kälteren Raum in den oberen, wärmeren Raum des Kessels.The pipes connect the lower part of the water chamber of the boiler c with the upper part of the water space and lead under the influence of the special execution particularly high heating given to them by the fire gases the water from the lower, colder room to the upper, warmer room of the boiler.
