Description
Steilrohrkessel. Es ist bekannt, bei Steilrohrkesseln die zuerst von den heißen Gasen getroffenen Wasserrohrreihen in ihrem oberen Teil dem Zuge der Heizgase vollständig durch Abdeckung zu entziehen, um eine Überlastung der Rohre infolge zu starker Dampfbildung zu vermeiden.Steep tube boiler. It is known that in steep tube boilers the first of the hot gases hit rows of water pipes in their upper part the course of the Completely withdraw hot gases through the cover to avoid overloading the pipes to avoid due to excessive steam formation.
Die Erfindung bezweckt, diese Bauart dadurch zu verbessern, daß die Lände der den Heizgasen entzogenen oberen Rohrenden um so kleiner wird, je weiter die Rohre von der Feuerung entfernt liegen. Dadurch wird erreicht, daß eine möglichst große Rohrlänge der Beheizung durch die Feuergase ausgesetzt ist, ohne die Rohre in ihrem oberen Teil, wo sie hauptsächlich von Dampf erfüllt sind, durch allzu starke Beheizung zu gefährden und ohne durch diese Beheizung eine zu hohe Belastung der Rohre mit Dampf und damit eine Stauung der Dampfabführung zu bewirken. Die Belastung der einzelnen Rohrreihen wird dadurch eine möglichst gleichmäßige und die Leistung des Kessels eine möglichst hohe.The invention aims to improve this type of construction in that the The length of the upper pipe ends withdrawn from the heating gases becomes smaller the further the pipes are away from the furnace. This ensures that one as possible long pipe length is exposed to the heating by the fire gases without the pipes in their upper part, where they are mainly filled with steam, by excessively strong ones To endanger the heating and without this heating an excessive load of the To effect pipes with steam and thus a stagnation of the steam discharge. The load of the individual rows of tubes is as uniform as possible and the performance of the boiler as high as possible.
In der Zeichnung ist an einem Steürohrkessel diese neue Bauart im senkrechten Querschnitt gezeigt. Von dem der Feuerteig zunächst liegenden Rohrbündel a sind durch die treppenförmige Abdeckung b die oberen Rohrenden staffelförmig in immer geringerer Ausdehnung abgedeckt, so zwar, daß die der Feuerung zunächst liegende Rohrreihe i in kürzester und die von den Feuergasen am entferntesten liegende Rohrreihe a in längster Ausdehnung von den Feuergasen bestrichen wird. Die Rohrreihe i erzeugt auf dem von den Feuergasen bestrichenen kurzen Teil ungefähr eb@ensoviel Dampf wie die von kälteren Gasen bestrichene und weniger vom Feuer bestrahlte Rohrreihe a, so daß die Belastung der Dampfaustrittsstelle mit abzuführendem Dampf auf diese Weise bei allen Rohrreihen ungefähr gleich groß ist. Bei dem hinteren Rohrbündel c des Kessels ist eine derartige Unterteilung nicht mehr notwendig, da die Rohre dieses Bündels verhältnismäßig wenig Dampf erzeugen und eine Dampfstauung in denselben erfahrungsgemäß nicht eintritt.In the drawing, this new design is on a control tube boiler vertical cross section shown. From the tube bundle next to the fire dough a, the upper tube ends are staggered in Covered with ever lesser extent, so that that of the furnace is closest to it Row of pipes i in the shortest and the row furthest away from the flue gases a is smeared in the longest extent by the fire gases. The pipe row i creates on the short part smeared by the fiery gases about eb @ ens as much steam as the row of pipes a coated with colder gases and less exposed to fire, so that the load on the steam outlet point with steam to be discharged on this Way is about the same size for all rows of pipes. At the rear tube bundle c of the boiler, such a subdivision is no longer necessary because the pipes this bundle produce relatively little steam and a steam accumulation in the same experience has shown that it does not occur.
