KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine weitere Ausbildung der Vorwärmeranlage für einen zusammengesetzten Schrägrohr-Steilrohrkessel nach Patent 248475 und besteht darin, daß die 5 Oberkessel und gegebenenfalls auch die Unterkessel der an den beiden Schmalseiten einer Steilrohrgruppe gelegenen Vorwärmer zu je einem Ober- bzw. Unterkessel vereinigt sind. Dadurch werden für den Vorwärmer größere Wasserräume und Heizflächen geschaffen, ohne den von Kessel und Vorwärmer beanspruchten Raum zu vergrößern, denn diese durchlaufenden Ober- und Unterkessel liegen in den schon vorhandenen und notwendigen Heizgaskanälen. Durch die Vergrößerung des Wasserinhalts wird die im Vorwärmer aufgespeicherte Wärmemenge vergrößert, der Kessel ist also besser imstande, längere Zeit plötzlich auftretende Steigerungen der Dampfentnähme zu leisten; ferner werden auch durch die Vergrößerung der Heizfläche die Heizgase besser ausgenutzt.The invention relates to a further embodiment of the preheater system for a composite Inclined tube-steep tube boiler according to patent 248475 and consists in the fact that the 5 upper boiler and possibly also the lower boiler the preheaters located on the two narrow sides of a group of steep pipes are combined to form an upper and lower boiler. This creates larger water spaces and heating surfaces for the preheater, without to enlarge the space occupied by the boiler and preheater, because these pass through The upper and lower boilers are located in the already existing and necessary hot gas ducts. By increasing the water content, the amount of heat stored in the preheater is increased, the boiler is therefore better able to deal with sudden increases in steam extraction for a longer period of time afford to; Furthermore, the heating gases are also due to the enlargement of the heating surface better used.
Fig. ι zeigt den Kessel in Seitenansicht. Das seitliche Mauerwerk ist fortgelassen, um Vorwärmer und Steilrohrgruppe zu zeigen.Fig. Ι shows the boiler in side view. The side masonry is omitted to To show preheater and steep pipe group.
Fig. 2 zeigt einen Querschnitt nach A-B von Fig. ι und Fig. 3 einen wagerechten Schnitt nach C-D von Fig. 2.FIG. 2 shows a cross section according to AB from FIG. 1 and FIG. 3 shows a horizontal section according to CD from FIG. 2.
Fig. 4 zeigt eine andere Ausführung in Seitenansicht, entsprechend Fig. 1.FIG. 4 shows another embodiment in side view, corresponding to FIG. 1.
Die Heizgase bestreichen die Schrägrohrgruppe ι und den Überhitzer 2, treten dann in die seitlichen Steilrohrgruppen 3 ein, die sie von oben nach unten durchstreichen. Unten treten die Heizgase an den beiden Schmalseiten aus und in die Vorwärmer 4 ein, die sie von unten nach oben durchstreichen ; oben werden sie in den Gaskanälen 7 abgeführt. Für je zwei Vorwärmergrupperi 4, die an den beiden Schmalseiten einer Steilrohrgruppe 3 liegen, ist je ein Oberkessel 5 und ein Unterkessel 6 vorgesehen, die in den oberen und unteren Gaskanälen liegen.The heating gases coat the inclined tube group ι and the superheater 2, then occur into the side steep pipe groups 3, which they cross from top to bottom. At the bottom, the heating gases exit on the two narrow sides and enter the preheater 4, which they pass through from bottom to top ; they are discharged into the gas channels 7 at the top. For every two preheater groups 4, which are located on the two narrow sides of a vertical tube group 3 is an upper boiler 5 each and a lower boiler 6 is provided which are located in the upper and lower gas passages.
Nach Fig. 4 kann auch der Unterkessel der Steilröhren verlängert werden, um die Vorwärmerröhren aufzunehmen. Es sind dann Trennwände 9 vorgesehen, und die Verbindung zwischen Vorwärmer und Kessel geschieht in üblicher Weise durch Leitungen mit Rückschlagventilen.According to FIG. 4, the lower boiler of the steep tubes can also be extended to include the preheater tubes to record. Partition walls 9 are then provided, and the connection between the preheater and boiler takes place in the usual way by lines with check valves.
