  Dampferzeuger. 



   Diese Erfindung bezieht sich auf solche Dampferzeuger, bei welchen die der unmittelbaren Einwirkung des Feuers ausgesetzten Teile durch enge, dickwandige Wasserrohre gebildet sind und besteht darin, dass diese Wasserrohre mit den weit gehaltenen   Dampferzeugungsrohren   durch   Zwischenstücke   verbunden sind, welche einen verengten Durchgangsquerschnitt aufweisen. Hiedurch wird erreicht, dass in den Wasserrohren ein Überdruck entsteht, der die Dampfentwicklung im Innern der   Wasserrohre   verhindert, so dass die Dampfabspaltung erst nach Übertritt des Wassers durch den verengten Querschnitt in die Dampferzeugungsrohre eintreten kann. 



   Eine beispielsweise Ausführungsform des den Erfindungsgegenstand bildenden   Zwischenstückes   ist in Fig. 1 in Ansicht und in Fig. 2 in Draufsicht dargestellt. 



   Der Dampferzeuger besteht in bekannter Art aus einer Anzahl enger, dickwandiger   Wasserrohre fl und ,   welche unmittelbar in den Feuerraum eingebaut sind und    l'en tibtr   letzteren angeordeten Dampferzeugungsrohren i1 und i2, welche verhältnismäfig welt gehalten sind. 



   Gemäss der Erfindung sind nun die   Wasserrohre fl, mit den Dampferzeugungs-   rohren i1, i2 durch Zwischenstücke g, h von T-förmiger Gestalt verbunden. In den Teil h mUnden dio Enden je zweier Dampferzengungsrohre i1, i2 und in den Teil g die Enden je zweier nebeneinanderliegender Wasserrohre f1, f2. 



   Der Durchgangsquerschnitt d vom Teil   9   in den Teil h ist   erhebtich kleiner gehalten,   als der Gesamtquerschnitt der in den Teil g ausmündenden Wasserrohrquershnitte, so dass in den Wasserrohren ein Überdruck entsteht, demzufolge sich innerhalb der Wasserrohre
Dampfblasen nicht abspalten. 



   Sobald aber das Wasser unter dem hohen Druck in die weitgehaltenen Dampf-   orzeugungsrohre   il, ja übergetreten ist, findet infolge der   Druckvcrminderung   eine spontane lobhafte Dampfentwicklung statt. 



   Es ist selbstverständlich, dass die Erfindung auch dann anwendbar ist, wenn nur je 
 EMI1.1 
 verbunden wird   ;   es wird   auch dann der Durchgangsquerschnitt des letzteren gegenüber   demjenigen des einmündenden Wasserrohres erheblich kleiner gehalten, während bei Ein- 
 EMI1.2 
   jenigen eines einzejnen Wasserrohres   gleich sein kann.

  Steam generator.



   This invention relates to such steam generators in which the parts exposed to the direct action of the fire are formed by narrow, thick-walled water pipes and consists in that these water pipes are connected to the widely held steam generating pipes by intermediate pieces which have a narrowed passage cross section. This ensures that an overpressure is created in the water pipes, which prevents the development of steam inside the water pipes, so that the steam can only be split off after the water has passed through the narrowed cross-section into the steam generation pipes.



   An example embodiment of the intermediate piece forming the subject matter of the invention is shown in FIG. 1 in a view and in FIG. 2 in a plan view.



   The steam generator consists in a known manner of a number of narrow, thick-walled water pipes F1 and, which are built directly into the combustion chamber and the steam generator pipes i1 and i2 arranged in the latter, which are kept relative to the world.



   According to the invention, the water pipes f1 are now connected to the steam generating pipes i1, i2 by intermediate pieces g, h of T-shape. The ends of two steam generation pipes i1, i2 each open into part h and the ends of two adjacent water pipes f1, f2 each open into part g.



   The passage cross section d from part 9 to part h is raised smaller than the total cross section of the water pipe cross section opening into part g, so that an overpressure arises in the water pipes, as a result of which there is within the water pipes
Do not split off vapor bubbles.



   But as soon as the water has passed under the high pressure into the steam-generating pipes, which are kept wide open, a spontaneous, laudable development of steam takes place as a result of the pressure reduction.



   It goes without saying that the invention is applicable even if only ever
 EMI1.1
 is connected; the passage cross-section of the latter is then kept considerably smaller compared to that of the water pipe flowing into it, while
 EMI1.2
   that of a single water pipe can be the same.
