Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft einen durch die Abgase des Kessels beheizten Röhrenvorwärmer, innerhalb dessen der Heizzug derart ausgebildet ist, daß die Gase gezwungen werden, zwischen die Vorwärmerröhren vorn oben, wo das wärmste Wasser in den Röhren ist, einzutreten und hinten unten, im Bereich des kältesten Wassers, auszutreten. Die Erfindung besteht darin, daß zwischen den Vorwärmerröhren im Anschluß an den Rauchabzug des Kessels weitere Kammern eingebaut sind, aus welchen die Abgase oben zu den Röhren übertreten.The invention relates to a tube preheater heated by the exhaust gases of the boiler, within which the heating flue is designed in such a way that the gases are forced to enter between the preheater tubes at the top, where the warmest water in the tubes is and at the back below, in the area of the coldest water, to exit. The invention consists in that between the preheater tubes in connection with the smoke outlet of the boiler, further chambers are built in, from which the exhaust gases go to the top of the pipes trespass.
Fig. ι zeigt die neue Vorwärmeranlage im wagerechten Schnitt nach C-D, Fig. 2, und Fig. 2 im Querschnitt nach A-B, Fig. 1. Das kalte Wasser tritt in den Vorwärmer unten bei α ein, und das warme Wasser wird oben bei b entnommen. Aus dem Fuchs c treten die Rauchgase in eine gemauerte Kammer dv die zwischen den Röhrenbündeln ex e-, angeordnet ist, so daß weniger Verluste an strahlender Wärme als bei seitlicher Lage der Kammer dx entstehen. In dieser Kammer άλ steigen die Heizgase nach oben und treten durch die Schlitze fx /i oben zwischen die Vorwärmerröhren ex O1 ein, und zwar an der Stelle, an der sich das wärmste Wasser befindet. Hiernach durchstreichen sie die Röhrenbündel von oben nach unten und. treten durch die Maueröffnungen gY gx in die Kammer d2, von wo aus sich derselbe Vorgang in den Röhrenbündeln e2 e2 wiederholt. Eine solche Wiederholung kann in weiter folgenden Röhrenbündeln stattfinden. Bei kleineren, verhältnismäßig hoch gebauten Vorwärmern genügt ein einmaliger Vorgang dieser Art zur vollständigen Ausnutzung der Heizgase, wobei dann die Heizgase unmittelbar durch die Öffnungen g\ gx nach dem Schornstein gehen.Fig. Ι shows the new preheater in a horizontal section according to CD, Fig. 2, and Fig. 2 in cross section according to AB, Fig. 1. The cold water enters the preheater at the bottom at α , and the warm water is at the top at b taken. From the fox c the flue gases pass into a bricked chamber d v which is arranged between the tube bundles e x e-, so that fewer losses of radiant heat occur than with the lateral position of the chamber d x . In this chamber ά λ , the heating gases rise and enter through the slots f x / i above between the preheater tubes e x O 1 , namely at the point where the warmest water is. Then cross the tube bundle from top to bottom and. pass through the wall openings g Y g x into chamber d 2 , from where the same process is repeated in the tube bundles e 2 e 2. Such a repetition can take place in subsequent tube bundles. In the case of smaller, relatively tall preheaters, a single process of this type is sufficient to fully utilize the heating gases, with the heating gases then going directly through the openings g \ g x after the chimney.
