KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die Erfindung betrifft einen stehenden Dampfkessel mit an einen oberen Wasser- und Dampfsammler angeschlossenen Fieldröhren. Bekannte derartige Kessel haben nur eine geringe Wärmeausnutzung, weil die Heizgase innerhalb des Kessels einen zu kurzen Weg zurücklegen und eine Durcheinander wirbelung dieser Gase nur in geringem Maße stattfindet, da ein Richtungswechsel nicht möglich ist. Die Erfindung soll diesem Mangel abhelfen und besteht darin, daß die Feuerbüchse des Kessels durch eng aneinanderstehende Fieldröhren mit oberen Einschnürungen zum Durchlaß der Feuergase gebildet ist.The invention relates to an upright steam boiler with an upper water and steam collector connected field tubes. Well-known such boilers have only a low heat utilization, because the heating gases travel too short a distance within the boiler and a confusion of these gases only takes place to a small extent, as there is a change of direction not possible. The invention is intended to remedy this deficiency and consists in that the firebox of the kettle through closely spaced field tubes with upper ones Constrictions for the passage of the fire gases is formed. Der' neue Kessel ist in Fig. ι und 2 im senkrechten und wagerechten Schnitt dargestellt. ■The 'new boiler is shown in Fig. Ι and 2 in vertical and horizontal section. ■ Der neue Kessel ist mit zwei Gruppen Fieldröhren B und C ausgerüstet, von denen die Röhren B an den Wasser- und Dampfsammler in der Mitte des Kessels angehängt sind und auf ihrer ganzen Fläche von den Gasen des auf dem Rost A brennenden Feuers bestrichen werden. Die Röhren C dagegen sind gemäß der Erfindung als Feuerbüchse im Kreise dicht aneinandergestellt und mit oberen Einschnürungen D zum Durchlaß der Feuergase versehen. Diese Gase können, nachdem sie an der Innenseite der Röhrengruppe C aufgestiegen sind, nur durch die von den 3c Einschnürungen D gebildeten Schlitze nach außen in den ersten Zug E- entweichen, aus dem sie durch die Öffnung F in den zweiten Zug G gelangen, wo sie wieder die Röhren C umströmen, um dann durch die Öffnung H in 3: den Feuerzug / einzutreten und wieder die Röhren C zu umstreichen, wonach sie bei K in den Fuchs entweichen. Durch den wiederholten Richtungswechsel und dadurch, daß die umspülte Wand aus lauter Halbzylindern besteht, wird eine innige Durchwirbelung der Feuergase erzielt, so daß sämtliche Heizgase auch mit der Heizfläche in Berührung kommen.The new boiler is equipped with two groups of field tubes B and C, of which tubes B are attached to the water and steam collector in the middle of the boiler and are covered over their entire surface by the gases from the fire burning on grate A. The tubes C, on the other hand, according to the invention, are arranged close together in a circle as a fire box and are provided with upper constrictions D for the passage of the fire gases. After they have risen on the inside of the tube group C , these gases can only escape to the outside through the slots formed by the 3c constrictions D into the first train E , from which they pass through the opening F into the second train G , where they again flow around the tubes C , then enter the fire train / through the opening H in 3: and again pass around the tubes C , after which they escape at K into the fox. Due to the repeated change of direction and the fact that the wall around which it is bathed consists of nothing but half-cylinders, an intimate swirling of the fire gases is achieved, so that all the heating gases also come into contact with the heating surface.
