Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device according to the preamble of claim 1.

Eine solche Vorrichtung ist aus der EP-A-128 252 bekannt. Dort tritt der getrocknete Sattdampf aus dem Wasserabscheider in einen Raum ein, der von der Austrittsseite des Wasserabscheiders, der Eintrittsfläche des Überhitzers und einem Teil der Innenwandung des Druckbehälters begrenzt ist. Der aus dem überhitzer austretende überhitzte Dampf tritt in einen Teilraum ein, der von der Austrittsfläche des überhitzers, Trennblechen und einem anderen Teil der Innenwandung des Druckbehälters begrenzt ist. Die bekannte Vorrichtung weist somit unterschiedliche Räume auf, in denen bei Betrieb der Vorrichtung stark unterschiedliche Temperaturen herrschen, so daß infolge der ungleichmäßigen Temperaturverteilung über den Umfang des Druckbehälters eine Verformung diese Behälters nicht auszuschließen ist.Such a device is known from EP-A-128 252. There the dried saturated steam from the water separator enters a space which is limited by the outlet side of the water separator, the inlet surface of the superheater and part of the inner wall of the pressure vessel. The superheated steam emerging from the superheater enters a partial space which is delimited by the outlet surface of the superheater, separating plates and another part of the inner wall of the pressure vessel. The known device thus has different rooms in which there are very different temperatures during operation of the device, so that a deformation of this container cannot be ruled out due to the uneven temperature distribution over the circumference of the pressure vessel.

Weitherhin ist eine Vorrichtung bekannt (EP-AI-0 005 225), bei der die beiden im Druckmantel untergebrachten Systeme, nämlich Wasserabscheider und überhitzer konstruktiv miteinander verbunden sind, und zwar über ihre Gesamtlänge. Aufgrund unterschiedlicher Temperaturen in beiden Systemen muß die Verbindung nicht nur schiebend, sondern auch gleichzeitig zur Vermeidung von Bypass-Strömungen dichtend hergestellt werden. Der Druckmantel wird auf seiner inneren Oberfläche gänzlich oder teilweise mit Naßdampf beaufschlagt und muß aus diesem Grund in kostenaufwendiger Weise gegen Korrosion durch Plattierung oder Leitbleche geschützt werden. Bei der bekannten Anordnung liegt eine parallele Anordnung der Wasserabscheideeinheiten zum zuströmenden Dampf vor. Zur gleichmäßigen Beaufschlagung der Wasserabscheideeinheiten mit dem im entstehenden Dampf befindlichen Wasser müssen erhebliche Widerstände in Form von Gleichrichtern installiert werden, die jeweils einen Druckverlust und somit eine Reduzierung der Leistung bedeuten.Furthermore, a device is known (EP-AI-0 005 225) in which the two systems accommodated in the pressure jacket, namely water separators and superheaters, are structurally connected to one another over their entire length. Due to different temperatures in both systems, the connection must not only be made pushing but also sealing to avoid bypass flows. The inner surface of the pressure jacket is partially or completely exposed to wet steam and must therefore be protected against corrosion by plating or baffles in a costly manner. In the known arrangement there is a parallel arrangement of the water separation units to the incoming steam. In order to evenly apply the water in the steam to the water separator units, considerable resistances in the form of rectifiers must be installed, each of which means a pressure loss and thus a reduction in performance.

Weiterhin sind Apparatekombinationen zum Trocknen von Dampf und anschließender überhitzung bekannt, z. B. durch DE-P-2 555 539.9-16, DE-P-3 307 101.2-16, DE-P-2 901 272 A1, US-PS-3 923 010, GB-OS-2 148 470 und DE-OS-3 307 101. Diese Apparate weisen einmal für bestimmte Turbinenkonstruktionen den Nachteil auf, daß der überhitzer und damit die Dampfaustrittsstutzen nur in einem eingeschränkten Raum anzuordnen sind. Durch diese Einschränkung sind aufwendige Dampfaustrittsleitungen und damit Druck- und Wärmeverluste zwangsläufig vorhanden.Furthermore, apparatus combinations for drying steam and subsequent superheating are known, e.g. B. by DE-P-2 555 539.9-16, DE-P-3 307 101.2-16, DE-P-2 901 272 A1, US-PS-3 923 010, GB-OS-2 148 470 and DE- OS-3 307 101. For certain turbine constructions, these apparatuses have the disadvantage that the superheater and thus the steam outlet connections can only be arranged in a restricted space. Due to this restriction, complex steam outlet lines and thus pressure and heat losses are inevitably present.

Aus der DE-OS-2 712 794 ist zwar eine Vorrichtung zum Trocknen und überhitzen von Dampf mit einem liegenden zylindrischen Druckbehälter bekannt, der eine gleichmäßige Temperaturbeaufschlagung seiner Innenwandung aufweist, jedoch wird dies durch eine im Druckbehälter angeordnete Innenhülle erreicht, die im wesentlichen den Behälterabmessungen angepaßt ist und eine zusätzliches Bauteil darstellt. Weiterhin ist von Nachteil, daß die Innenwandung des Druckbehälters insgesamt unter der hohen Überhitzerausgangstemperatur steht.From DE-OS-2 712 794 a device for drying and superheating steam with a horizontal cylindrical pressure vessel is known, which has a uniform temperature application of its inner wall, but this is achieved by an inner shell arranged in the pressure vessel, which essentially corresponds to the container dimensions is adapted and represents an additional component. Another disadvantage is that the inner wall of the pressure vessel is generally below the high superheater outlet temperature.

Es ist daher die Aufgabe der vorliegenden Erfindung, ausgehend von aus der EP-A1-128 252 bekannten Vorrichtung eine Vorrichtung zu schaffen, bei der der Temperaturverlauf über den Umfang des Druckbehälters vergleichmäßigt werden soll.It is therefore the object of the present invention to create, on the basis of the device known from EP-A1-128 252, a device in which the temperature profile is to be made uniform over the circumference of the pressure vessel.

Diese Aufgabe wird dadurch gelöst, daß der Wasserabscheider und der Überhitzer so angeordnet sind, daß sie von Dampf im wesentlichen frei umströmbar sind, so daß nach dem Verlassen des Wasserabscheiders der getrocknete Sattdampf die gesamte Innenwandung des Druckbehälters beaufschlagt und den Wasserabscheider sowie den überhitzer praktisch vollständig umspült.This object is achieved in that the water separator and the superheater are arranged so that steam can flow around them essentially freely, so that after leaving the water separator the dried saturated steam acts on the entire inner wall of the pressure vessel and the water separator and the superheater are practically completely washed around.

Somit wird erreicht, daß die Innenwandung des Druckbehälters sowohl in der Länge als auch auf dem Umfang mit Dampf gleicher Temperatur beaufschlagt wird, wobei diese die relativ niedrige Temperatur des getrockneten Sattdampfes ist. Plattierungen an der Innenwandung des Druckbehälters können eingespart werden. Es ist keine geschlossene zusätzliche Innenhülle notwendig.It is thus achieved that the inner wall of the pressure vessel is acted upon with steam of the same temperature both in length and on the circumference, this being the relatively low temperature of the dried saturated steam. Plating on the inner wall of the pressure vessel can be saved. There is no need for a closed additional inner shell.

Die Länge des Druckbehälters kann der Länge einer ND-Turbine angepaßt sein. Durch dieses Konzept wird eine äußerst günstige Führung der Dampfaustrittsleitungen erreicht. Die Leitungen können sehr kurz sein, somit ist der Druck- und der Wärmeverlust gering.The length of the pressure vessel can be adapted to the length of an LP turbine. This concept ensures that the steam outlet lines are routed extremely cheaply. The lines can be very short, so the pressure and heat loss is low.

Neben der Verbindung zu dem seitlichen Dampfeintrittsstutzen und zu dem mindestens einen Dampfauslaßstutzen ist eine wärmebewegliche Befestigung der beiden Baugruppen an der Innenwandung des Druckbehälters erforderlich.In addition to the connection to the lateral steam inlet connection and to the at least one steam outlet connection, a heat-mobile attachment of the two assemblies to the inner wall of the pressure vessel is required.

Dabei wird bevorzugt, daß der überhitzer abgestützt und der Abscheider aufgehängt sind, da dieses an gemeinsamen Kragarmen erfolgen kann.It is preferred that the superheater is supported and the separator is suspended, since this can be done on common cantilever arms.

Weiterhin kann es zweckmäßig sein, daß der Überhitzer an Zugankern an der Wandung des Druckbehälters aufgehängt ist.It may also be expedient that the superheater is suspended from tie rods on the wall of the pressure vessel.

Schließlich ist es möglich, daß der Abscheider abgestützt ist.Finally, it is possible that the separator is supported.

Für den Wasserabscheider wird bevorzugt, daß er in Richtung der Behälterachse die Gestalt eines Pyramiden- oder Kegelstumpfes aufweist, und die den Wasserabscheider bestimmenden Wasserabscheideeinheiten mit ihrer Dampfanströmfläche zur Achse des Behälters unter einem Winkel a zwischen 10° und 90 ageordnet sind.It is preferred for the water separator that it has the shape of a truncated pyramid or truncated cone in the direction of the container axis, and that the water separator units determining the water separator are arranged with their steam inflow surface to the axis of the container at an angle α between 10 ° and 90 °.

Die Erfindung soll nun anhand der beigefügten Figuren näher erläutert werden. Es zeigen:

  • Fig. 1 eine Ansicht eines vertikalen Längsschnittes mit einer ersten Halterung von Abscheider und Überhitzer:
  • Fig. 2 eine Ansicht des horizontalen Längsschnittes II - 11 des Wasserabscheiders;
  • Fig. 3 eine Ansicht des Behälterquerschnittes 111 - 111 mit der ersten Halterung;
  • Fig. 4 eine Ansicht des Behälterquerschnittes IV - IV mit einer zweiten Halterung und
  • Fig. 5 eine Anordnung zweier erfindungsgemäßer Vorrichtungen an einer HD-Dampfturbine.
The invention will now be explained in more detail with reference to the accompanying figures. Show it:
  • Fig. 1 is a view of a vertical longitudinal section with a first bracket of separator and superheater:
  • Figure 2 is a view of the horizontal longitudinal section II - 11 of the water separator.
  • 3 shows a view of the container cross section 111-111 with the first holder;
  • Fig. 4 is a view of the container cross section IV - IV with a second bracket and
  • Fig. 5 shows an arrangement of two devices according to the invention on an HD steam turbine.

Der in dem HD-Teil der Turbine entspannte und damit nasse Dampf tritt über einen oder mehrere Stutzen 2 in den Wasserabscheider 3 ein. Der Wasserabscheider wird aus Leitblechen 4 und Wasserabscheideeinheiten 5 gebildet. Der Wasserabscheider verjüngt sich - auf der Zuströmseite - auf seiner gesamten Länge. Durch diese Verjüngung und die unter einem Winkel a von 10° bis 90° zur Hauptströmungsrichtung angeordneten Dampfausströmflächen 5a der Wasserabscheideeinheiten 5 wird eine nahezu gleichmässige Deaufschlagung der Wasserabscheideeinheiten 5 erreicht. Gleichrichter in Form von jalousieartigen Blechen und/oder Lochblechen sind nur in geringem Ausmaß erforderlich. Der Naßdampf gelangt aus dem oder den Eintrittsstutzen 2 unmittelbar in das Innere des Wasserabscheiders. Beim Durchströmen des Dampfes durch die Wasserabscheideeinheiten 5 wird der Dampf mechanisch getrocknet. Zur Verbesserung des Wirkungsgrades des Wasserabscheidungssystems und zur Reduzierung der Aufwendungen zur gleichmäßigen Dampf-Wasserbeaufschlagung wird die Dampfeintrittsgeschwindigkeit durch entsprechende Dimensionierung des Zuströmquerschnittes des Abscheidungssystems herabgesetzt. Schwallwasser und/oder größere Wassertropfen fallen aus dem Dampfstrom aus und werden über ein separates, am unteren Dampfleitblech angeordnetes Abführsystem 6 abgeleitet. Der so getrocknete Dampf kommt erst jetzt mit der Wandung des Druckmantels 1 in Berührung. An den nicht plattierten Druckmantelwandungen können keine wasserbedingten Korrosionen auftreten.The steam, which is relaxed and thus wet in the HP part of the turbine, enters the water separator 3 via one or more connecting pieces 2. The water separator is formed from baffles 4 and water separator units 5. The water separator tapers - on the inflow side - along its entire length. This taper and the steam outflow surfaces 5a of the water separation units 5 arranged at an angle a of 10 ° to 90 ° to the main flow direction achieve an almost uniform impingement of the water separation units 5. Rectifiers in the form of blind-like sheets and / or perforated sheets are only required to a small extent. The wet steam arrives from the inlet port 2 directly into the interior of the water separator. When the steam flows through the water separation units 5, the steam is mechanically dried. In order to improve the efficiency of the water separation system and to reduce the expenditure for the uniform application of steam to water, the steam entry speed is reduced by appropriately dimensioning the inflow cross section of the separation system. Splash water and / or larger water drops fall out of the steam flow and are discharged via a separate discharge system 6 arranged on the lower steam baffle. The steam thus dried only comes into contact with the wall of the pressure jacket 1. No water-related corrosion can occur on the unplated pressure jacket walls.

Oberhalb des Wasserabscheiders 3 ist der Überhiter 7, der sich ebenfalls über die gesamte Behälterlänge erstreckt, angeordnet. Der ein-oder mehrflutige und/oder ein- oder mehrstufige Überhitzer besteht im wesentlichen aus den Rohrbündeln 8, die sowohl als U-Rohr- oder Geradrohrwärmetauscher ausgebildet werden können. Zum Ablauf des beim Wärmeaustausch entstehenden Kondensats innerhalb der Rohre können die Rohrbündel 8 geneigt und/oder mit sogenanntem Treibdampf betrieben werden.Above the water separator 3, the superheater 7, which also extends over the entire length of the container, is arranged. The single- or multi-flow and / or single- or multi-stage superheater essentially consists of the tube bundles 8, which can be designed both as a U-tube or straight tube heat exchanger. The tube bundles 8 can be inclined and / or operated with so-called motive steam to allow the condensate formed during the heat exchange to run off.

Der in den Rohrbündeln 8 überhitzte Dampf wird über Leitbleche 9, die nur an den Auslaßststuzen 10 mit dem Druckmantel 1 verbunden sind, aus dem Apparat herausgeführt.The steam overheated in the tube bundles 8 is led out of the apparatus via baffles 9, which are only connected to the pressure jacket 1 at the outlet supports 10.

Wie aus Fig. 1 und 3 ersichtlich ist, sind die Baugruppen des Überhitzers 7 über Zuganker 11 am Behältermantel 1 abgehängt, während der Wasserabscheider 3 auf mit dem Druckmantel 1 verschweißten Konsolen 12 gleitend abgestützt ist.As can be seen from FIGS. 1 and 3, the assemblies of the superheater 7 are suspended from the tank jacket 1 via tie rods 11, while the water separator 3 is supported in a sliding manner on brackets 12 welded to the pressure jacket 1.

Im Schnitt nach Fig. 4 wird eine andere Ausführungsform der Halterung gezeigt. Seitlich sind an der Innenwandung des Druckmantels 1 Kragarme 13 in Form eines I-Eisens befestigt. Auf diesen ist der Überhitzer 7 durch Gleitschuhe 14 schiebend abgestützt, während der Wasserabscheider 3 mit über den unteren Flansch des I-Eisens greifenden Aufhängungen 15 schiebend an den Kragarmen 13 angehängt ist.4 shows another embodiment of the holder. Cantilever arms 13 in the form of an I-iron are attached laterally to the inner wall of the pressure jacket. The superheater 7 is slidably supported on these by sliding shoes 14, while the water separator 3 is slidably attached to the cantilever arms 13 by means of suspensions 15 which grip over the lower flange of the I-iron.

In der Fig. 5 ist die Zuordnung zweier Vorrichtungen zu einer Turbine gezeigt, die die kurze Verbindung der Austrittsstutzen 10 mit dem Turbinengehäuse veranschaulicht.5 shows the assignment of two devices to a turbine, which illustrates the short connection of the outlet connections 10 to the turbine housing.

Auf die aus den Fig. 1, 3 und 4 ersichtliche Zuordnung der einzelnen Baugruppen wird ausdrücklich verwiesen. Bei einer Ausführungsform gemäß Fig. 1, 3 und 4 mit zwei Überhitzerbaugruppen wird zwischen diesen ein Strömungswiderstand eingebaut, wie in Fig. 1 bei 7a angedeutet.Reference is expressly made to the assignment of the individual assemblies which can be seen from FIGS. In an embodiment according to FIGS. 1, 3 and 4 with two superheater assemblies, a flow resistance is installed between them, as indicated in FIG. 1 at 7a.
