Abstract

A power station is formed of a plurality of mobile modules. One of the mobile modules is a connecting module which has only connecting lines, control equipment, cut-off equipment and measuring equipment installed therein. The connection module can be used for different power stations, which allows a cost-effective construction of power stations. Further, fittings which have to be monitored and operated are concentrated in the connecting module, which reduces operating costs of the power station.

Die Erfindung betrifft ein Kraftwerk, insbesondere Industriekraftwerk, aus mobilen Modulen, von denen einer als Verknüpfungsmodul ausgebildet ist.The invention relates to a power plant, in particular industrial power plant, from mobile modules, one of them as a link module is trained.

Beim Bau von Kraftwerksanlagen, beispielsweise von Industriekraftwerken, wird bisher üblicherweise jedes Projekt durch Spezialisten neu konzipiert. Der hierfür erforderliche Aufwand ist dadurch schon im Angebotsstadium sehr hoch. Die Entwicklung projektspezifischer Lösungen ist vor allem deswegen aufwendig, weil jede Fachabteilung für jedes Projekt eine Neuauslegung vornehmen muß und weil bei der Herstellung und dem Bau eine Vielzahl von Einzelteilen in Einzelanfertigungen hergestellt werden müssen.In the construction of power plants, such as industrial power plants, is usually every project through Specialists redesigned. The required effort This makes it very high even at the tender stage. The development project-specific solutions is above all because of that consuming, because each department for each project one Re-design must be made and because in the production and the construction of a variety of items in custom-made must be made.

Bisher wurde versucht den hierdurch bedingten Aufwand dadurch zu reduzieren, daß Spezialisten aus früheren oder ähnlichen Projekten möglichst viel einschlägige Tätigkeiten und vorhandene Bauteile für jüngere Projekte zu übernehmen hatten.So far, it has been trying the resulting effort to reduce that specialist from previous or similar Projects as much as possible relevant activities and existing ones Had to take over components for younger projects.

Aus der US 3,925,679 ist ein modular aufgebautes Kraftwerk bekannt, das ein zentrales Steuerungsmodul umfasst. In diesem Steuerungsmodul sind eine Vielzahl von Überwachungs-, Steuerungs-Energieversorgungs- und Bedienüngselemente angeordnet. Eine solche Steuerungszentrale ist auf die Bedürfnisse und Funktionen des jeweiligen Kraftwerks ausgerichtet und ist in gleicher Bauweise nicht modular in verschiedenen Kraftwerken einsetzbar. Hierdurch ist die Planungs- und Bauphase des Kraftwerks mit einem erheblichen Aufwand verbunden. Außerdem sind bei dieser Lösung zentrale Kraftwerkseinrichtungen auf die verschiedensten Modulen des Kraftwerks verteilt. Dadurch ist vor allem die Bedienung der Anlage erschwert. From US 3,925,679 is a modular power plant known, comprising a central control module. In this Control module are a variety of monitoring, control power supply and operating elements arranged. Such a control center is responsive to the needs and Functions of the respective power plant and is in same design not modular in different power plants used.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß in dem Verknüpfungsmodul neben Verbindungsleitungen ausschließlich Rohrleitungsarmaturen und Meßeinrichtungen eingebaut sind. Dabei besteht der Verknüpfungsmodul im Kern aus einem allseitig offenen Gerüst, in dem eine durchgehende Verbindungsleitung als Frischdampfleitung dient, neben der eine Prozeßdampfleitung vorgesehen ist.This object is achieved in that in the Linking module next to connecting lines exclusively Pipe fittings and measuring devices are installed. In this case, the linking module in the core consists of one side open scaffolding, in which a continuous connecting line serves as a main steam line, in addition to a process steam line is provided.

Die Frischdampfleitung ist aus einem Dampferzeuger gespeist und versorgt ihrerseits neben einer Turbine über eine Umformstation die Prozeßdampfleitung und über mindestens ein Absperrventil mindestens eine Turbine zum Antrieb einer Speisewasserpumpe mit Frischdampf.

Die Prozeßdampfleitung ist außer aus der Umformstation sowohl mit Dampf aus einem Hilfsdampferzeuger als auch mit Abdampf aus einer Turbine zum Antrieb einer Speisewasserpumpe mit Dampf versorgt. Zur Regelung des Dampfzustandes des über eine Umformstation in die Prozeßdampfleitung eingespeistem Frischdampf ist die Umformstation mit Wasser beaufschlagbar. Die Prozeßdampfleitung kann auch zur Versorgung einer Fernheizung herangezogen sein.The process steam line is except from the forming station both with steam from an auxiliary steam generator as well as with exhaust steam from a turbine to drive a feedwater pump with Steam supplied. For controlling the steam condition of over a Forming station in the process steam line fed live steam the forming station can be charged with water. The Process steam line can also be used to supply district heating be used.

Je eine Kondensatleitung für Kondensat aus Turbinenabdampf und aus Prozeßabdampf münden in den Verknüpfungsmodul, in dem außerdem mindestens je eine Saugleitung und eine Druckleitung mit Armaturen für Speisewasser vorgesehen sind, wobei die Prozeßdampfleitung innerhalb des Verknüpfungsmoduls einen Anschluß aufweist, der über ein Ventil mit einer Entgasungsleitung verbunden ist.

The containers are standard containers formed or with respect to the width and / or length and / or Height in integral reductions or enlargements of the Standard container dimensions.

Die erfindungsgemäße Ausführung eines Verknüpfungsmoduls für ein modular aufgebautes Kraftwerk ist sehr vorteilhaft, weil hierdurch neben einer einfachen, immer wieder verwendbaren Flanung außerdem eine übersichtliche Anordnung der Armaturen und eine logistisch einfache Bedienung derselben gewährleistet ist.The inventive embodiment of a link module for a modular power plant is very advantageous because This in addition to a simple, reusable Flanung also a clear arrangement of the fittings and a logistically simple operation of the same guaranteed is.

Eine Kondensatleitung vom Kondensator 11 mündet in eine Kondensatarmatur 17 und eine Kondensatleitung aus dem Prozeßdampfkreislauf mündet in eine Kondensatarmatur 18. Zur Gewährleistung eines störungsfreien Betriebes ist die Prozeßdampfleitung 4 außerdem über ein Ventil 19 an eine zu einem nicht dargestellten Entgaser führende Leitung anschließbar.A condensate line from the condenser 11 opens into a condensate fitting 17 and a condensate line from the process steam cycle opens into a condensate fitting 18. For warranty a trouble-free operation is the process steam line 4 also has a valve 19 to one to a Entgaser leading line not shown connected.

Auch jeweils mindestens eine Saugleitung 20 und eine Druckleitung 21 für Kesselspeisewasser sind durch den Verknüpfungsmodul geführt und weisen dort nicht dargestellte Armaturen auf.Also in each case at least one suction line 20 and a pressure line 21 for boiler feed water are through the linking module guided and have not shown fittings there on.
