außerhalb der Turbine,outside the turbine,

Patentiert im Deutschen Reiche vom 22. Dezember 1905 ab.Patented in the German Empire on December 22nd, 1905.

Bei Dampfturbinen mit stufenweiser Wiedererhitzung des Dampfes durch die Feuergase in besonderen, außerhalb der Turbine angeordneten Überhitzern pflegte man bisher die Überhitzer der einzelnen Turbinenstufen hintereinander anzuordnen, und zwar vor oder hinter dem meist ebenfalls in den Kesselzügen oder dem Fuchs angeordneten Vorwärmer und Dampftrockner oder Überhitzer. Hierbei ergibt sich der Nachteil, daß sich die Verteilung der Wärme von den Heizgasen auf die verschiedenen Apparate schwer oder gar nicht überwachen läßt, so daß ein rationelles Berechnen der erforderlichen Heizflächen für die verschiedenen Überhitzer unmöglich ist. Ein weiterer Nachteil besteht darin, daß das Verhältnis der Wärmeaufnahme zwischen den verschiedenen Überhitzern sich ändert, wenn bei Schwankungen der Turbinenbelastung eineIn steam turbines with gradual reheating of the steam by the fire gases Up to now, the was maintained in special superheaters arranged outside the turbine To arrange superheaters of the individual turbine stages one behind the other, in front of or behind the preheater and, which are usually also arranged in the boiler passes or in the fox Steam dryer or superheater. This has the disadvantage that the distribution the heat from the heating gases to the various devices is difficult or not at all can be monitored, so that a rational calculation of the required heating surfaces for the various superheaters is impossible. Another disadvantage is that the Ratio of heat absorption between the different superheaters changes when with fluctuations in the turbine load a

Änderung in der Beschickung der Feuerung vorgenommen wird.Change is made in the charging of the furnace.

Diese Nachteile werden gemäß vorliegender Erfindung dadurch vermieden, daß die Überhitzer der verschiedenen Turbinenstufen sämtlieh in ein und derselben Temperaturzone der Heizgase angeordnet sind. Diese Anordnung ermöglicht ein genaues rechnungsmäßiges Verfolgen des Wärmeaustausches zwischen den Heizgasen und den Überhitzern und bietet ferner den Vorteil, daß bei Änderungen der Beschickung die Änderung des Wärmeaustausches sich auf alle Überhitzer in der gleichen Weise überträgt, so daß bei einmal richtig bemessener Bauart der Anlage das Heizverhältnis für alle Belastungsfälle richtig bleibt. These disadvantages are avoided according to the present invention in that the superheater of the various turbine stages all in one and the same temperature zone of the Heating gases are arranged. This arrangement enables accurate accounting tracking the heat exchange between the heating gases and the superheaters and also has the advantage that when changes are made to the Charging the change in heat exchange affects all superheaters in the same Way, so that once correctly dimensioned the design of the system, the heating ratio remains correct for all load cases.

In den Zeichnungen ist die Erfindung beispielsweise und schematisch veranschaulicht. •Es sind: .The invention is illustrated schematically and by way of example in the drawings. •There are: .

Fig. ι die schematisch angedeutete bisherige Bauart der Dampfturbine,Fig. Ι the schematically indicated previous design of the steam turbine,

Fig. 2 schematisch eine Ausführungsform der Bauart gemäß der Erfindung,Fig. 2 schematically shows an embodiment of the type according to the invention,

Fig. 3 und 4 Ausführungsformen der Erfindung im Grundriß und Aufriß mit vier parallel geschalteten Überhitzern.3 and 4 embodiments of the invention in plan and elevation with four superheaters connected in parallel.

In der schematischen Darstellung nach Fig. ι bezeichnet Pfeil α die Richtung der Heizgase, in deren Weg vier Rohrsysteme 1, 2, 3, 4 hintereinander eingebaut sind, wovon die mittleren 3 und 4 Zwischenüberhitzer für die dreistufige Dampfturbine 5, 6, 7 darstellen.In the schematic representation according to FIG. 1, arrow α denotes the direction of the heating gases, in the path of which four pipe systems 1, 2, 3, 4 are installed one behind the other, of which the middle 3 and 4 represent reheaters for the three-stage steam turbine 5, 6, 7.

Im Gegensatz zu dieser bisher bekannten Bauart sind beim Beispiel nach Fig. 2 drei Rohrsysteme 8/9, 10 schematisch dargestellt, die sämtlich nebeneinander in der Längsrichtung des Feuerzuges verlaufen, so daß sie völlig gleichem Einfluß von Seiten der Heizgase unterliegen.In contrast to this previously known type, there are three in the example according to FIG Pipe systems 8/9, 10 shown schematically, all side by side in the longitudinal direction of the fire train run, so that they have completely the same influence on the part of the heating gases subject.

Bei der in Fig. 3 und 4 dargestellten Ausführungsform verlaufen die Feuerungsgase von dem Rost 14 über die Feuerbrücke 15 durch einen längs verlaufenden Zug 16, um schließlich in den Fuchs 17 einzumünden. In dem Längszug befinden sich eine oder mehrereIn the embodiment shown in FIGS. 3 and 4, the combustion gases run from the grate 14 over the fire bridge 15 by a longitudinal train 16 to finally open into the fox 17. In the longitudinal pull is one or more

Rohrschlangen 18, die vorteilhaft von außerhalb des Zuges angeordneten Sammelkästen 19 ausgehen. In der Kammer vor dem Eingang zum Fuchs 17 ist noch ein weiteres Rohrbündel 20 mit einem innerhalb und einem außerhalb angeordneten Sammelkasten "21 angeordnet. Wie die Fig. 4 zeigt, sind in dem Zug 16 vier Gruppen von Rohrschlangen 18 angeordnet, die als Überhitzer für die ver-Coiled tubes 18, which are advantageously arranged from collecting boxes outside the train 19 go out. There is another one in the chamber in front of the entrance to Fuchs 17 Tube bundle 20 with a collecting box "21" arranged inside and outside. As FIG. 4 shows, there are four groups of pipe coils 18 in the train 16 arranged as a superheater for the

10, schiedenen Turbinenstufen dienen und entsprechend dem für jede Turbinenstufe anderen Heizbedarf verschiedene Abmessungen erhalten. Es empfiehlt sich, die vier Überhitzer durch Seitenwandungen 22 voneinander zu trennen und in einzelne Kammern zu zerlegen, damit das Überfließen der Heizgase von einer stark besetzten Kammer in eine weniger stark besetzte verhindert wird.
An Stelle der dargestellten Ausführungs-
10, different turbine stages are used and are given different dimensions according to the different heating requirements for each turbine stage. It is advisable to separate the four superheaters from one another by side walls 22 and to divide them into individual chambers so that the overflow of the heating gases from a heavily occupied chamber into a less heavily occupied one is prevented.
Instead of the illustrated embodiment

ao formen können noch manche andere Ausführungsformen der Erfindung Verwendungfinden. So können z. B. .die in Fig. 3 stehend gezeigten Rohrschleifen liegend angeordnet werden oder die Überhitzer der verschiedenen Turbinenstufen können nicht nur seitlich nebeneinander, sondern auch über- bzw. untereinander angeordnet sein, die dann durch wagerechte Zwischenwände voneinander abgetrennt werden.Other embodiments of the invention may also find use. So z. B.. The pipe loops shown standing in Fig. 3 are arranged horizontally or the superheaters of the various turbine stages can not only be side by side, but also above or below each other, which are then through horizontal Partition walls are separated from each other.
