Description
Die Erfindung betrifft eine Anordnung umfassend eine Dampfturbine mit einem zweischaligen Gehäuse, welches ein Außengehäuse und ein darin angeordnetes Innengehäuse umfasst, und einen durch das Außengehäuse geführten Anschluss, wobei der Anschluss mit einem Paar von Anschlussöffnungen, gebildet durch eine erste Anschlussöffnung und eine zweite Anschlussöffnung gestaltet ist, welche am Innengehäuse ausgebildet sind, ferner umfassend ein erstes Ventil zum Zuführen von Dampf in das Innengehäuse, wobei das erste Ventil strömungstechnisch mit der ersten Anschlussöffnung verbunden ist.The invention relates to an arrangement comprising a steam turbine with a double-shell housing, which comprises an outer housing and an inner housing arranged therein, and a terminal guided through the outer housing, wherein the terminal with a pair of terminal openings, formed by a first connection opening and a second connection opening is, which are formed on the inner housing, further comprising a first valve for supplying steam into the inner housing, wherein the first valve is fluidly connected to the first connection opening.
Dampfturbinen werden zur Erzeugung von elektrischer Energie eingesetzt. Im Normalbetrieb wird ein Dampf im Dampferzeuger erzeugt und zur Dampfturbine zu einem Einströmbereich geführt. In der Dampfturbine wird die thermische Energie des Dampfes in mechanische Rotationsenergie des Rotors umgewandelt. Es sind allerdings Betriebszustände möglich, wo mehr Leistung von der Dampfturbine gefordert wird, was dadurch erreicht wird, dass im Dampferzeuger eine Zusatzbefeuerung eingesetzt wird, die zu einer Erhöhung des Dampfmassenstroms führt. Diese Erhöhung des Dampfmassenstromes wird in die Dampfturbine in bekannter Weise über stromabwärts im Beschaufelungsbereich liegende Überlasteinströmbereiche zugeführt. Dazu wird von der Frischdampfleitung eine Abzweigung realisiert, die strömungstechnisch stromabwärts mit dem Überlasteinströmbereich verbunden wird.Steam turbines are used to generate electrical energy. In normal operation, a steam is generated in the steam generator and fed to the steam turbine to an inflow. In the steam turbine, the thermal energy of the steam is converted into mechanical rotational energy of the rotor. However, operating conditions are possible where more power is required from the steam turbine, which is achieved by using additional firing in the steam generator, which leads to an increase in the steam mass flow. This increase in steam mass flow is supplied to the steam turbine in a known manner via overflow inflow regions located downstream in the blading area. For this purpose, a branch is realized by the main steam line, which is fluidly connected downstream with the Überlasteinströmbereich.
In dieser Überlastleitung ist ein Überlastventil angeordnet, das im Normalfall geschlossen ist. In der Frischdampfleitung ist ein Schnellschluss- und ein Stellventil angeordnet. Das Überlastventil wird in manchen Ausführungsformen unterhalb der Dampfturbine angeordnet, was zu unnötigen zusätzlichen Rohrleitungsverbindungen führt. Zusätzlich muss das Überlastventil und die Rohrleitungen gehaltert werden, welches zusätzlichen Aufwand darstellt. Das Überlastventil wird unterhalb der Turbinenmitte positioniert, wodurch die Entwässerung des Überlastventils ein absoluter Tiefpunkt wird und somit eine Entwässerungsstation zwingend erforderlich macht.In this overload line an overload valve is arranged, which is normally closed. In the main steam line a quick-closing and a control valve is arranged. The overload valve is disposed below the steam turbine in some embodiments, resulting in unnecessary additional piping connections. In addition, the overload valve and piping must be supported, which additional Expense represents. The overload valve is positioned below the center of the turbine, making drainage of the overload valve an absolute low point, making a dewatering station mandatory.
Aufgabe der Erfindung ist es eine kostengünstigere Anordnung für den Überlastbetrieb anzugeben.The object of the invention is to provide a more cost-effective arrangement for overload operation.

Likewise, can be dispensed with an additional dewatering station. The first valve and the second valve are arranged comparatively at a small distance from each other on the steam turbine.
