Description

Die Erfindung bezieht sich auf Gasturbinenanlagen, insbesondere zum Antrieb von Schiffen, aus mindestens je einer über ein gemeinsames Getriebe auf die Schraubenwelle geschalteten Vorwärts- und Rückwärtsturbine. Bei diesen Anlagen tritt, sofern jeweils eine der Turbinen bei Arbeiten der Anlage leer mitgeschleppt wird, ein erheblicher Leistungsverlust durch Ventilationsarbeiten der leer laufenden Turbine auf. Außerdem erwärmt sich der mitgeschleppte Turbinenläufer sowie das- Gehäuse unzulässig, so daß Havarien zu befürchten sind. Es ist bei Dampfturbinen bekannt, die jeweils leer mitgeschleppte Turbine an den Kondensator anzuschließen und damit unter Vakuum zu setzen. Damit. werden die oben geschilderten Verluste und Nachteile weitgehend verringert. Die Übertragung der bekannten" Einrichtungen für Dampfturbinen auf Gasturbinen scheitert jedoch am Fehlen des Kondensators. Die Erfindung erstrebt daher durch geeignete Mittel auch für Gasturbinen die oben geschilderten Vorteile des Kondensators.The invention relates to gas turbine systems, in particular for Propulsion of ships, made up of at least one each via a common gear the propeller shaft switched forward and reverse turbine. With these systems occurs if one of the turbines is dragged along empty while the system is working becomes, a considerable loss of performance due to ventilation work of the idle Turbine on. In addition, the dragged-along turbine rotor and the Housing impermissible so that accidents are to be feared. It's with steam turbines known to connect the turbine that is dragged along empty to the condenser and thus put under vacuum. In order to. the losses outlined above and disadvantages largely reduced. The transfer of the known "facilities for steam turbines on gas turbines, however, fails due to the lack of a condenser. the The invention therefore strives for the above-described gas turbines by suitable means as well Advantages of the capacitor.

Zu diesem Zweck sind gemäß der Erfindung eine Vakuumpumpe oder ein Strahler vorgesehen, die mit der Rückwärts- und der Vorwärtsturbine über ein Wechselventil verbunden ist, das j eweils mit den Fahrventilen derart verblockt sein kann, daß die leerlaufende Turbine mit der Pumpe bzw. mit dem Strahler verbunden ist. Hierbei empfiehlt es sich, zur Absperrung des Turbinenraumes gegen die Atmosphäre ein betriebsfremdes Mittel, beispielsweise Sperrdampf oder Sperrwasser, zu verwenden, da anders ein Untervakuumsetzen des Turbinenraumes nicht möglich ist. Durch entsprechende Betätigung des Steuerventils kann nun jeweils die leer laufende Turbine durch Anschluß an den Strahler bzw. die Vakuumpumpe unter Vakuum gesetzt werden, so daß Schäden in der Turbine und Ventilationsverluste nicht mehr zu befürchten sind.For this purpose are according to the invention a vacuum pump or a Emitters provided that connect to the reverse and the forward turbine via a shuttle valve is connected, which can be blocked in each case with the travel valves in such a way that the idling turbine is connected to the pump or to the emitter. Here it is advisable to use an external one to shut off the turbine room from the atmosphere Means, for example sealing steam or sealing water, to be used, as a different one Undervacuating the turbine room is not possible. By corresponding actuation of the control valve can now each idle turbine by connecting to the Emitter or the vacuum pump are placed under vacuum, so that damage in the Turbine and ventilation losses are no longer to be feared.

Die Zeichnung zeigt schematisch eine Anlage gemäß der Erfindung.The drawing shows schematically a plant according to the invention.

In der Zeichnung bedeuten: A den Kompressor für die Förderung der Brennluft, B die Turbine zum Antrieb des Kompressors, C den Motor zum Anfahren der Anlage, D die Vorwärtsturbine, E die Rückwärtsturbine, F das beiden gemeinsame Getriebe, H die Brennkammer, I das Vorwärtsfahrventil, K das Rückwärtsfahrventil, L den Dampfstrahler zum Untervakuumsetzen beider Turbinen, M den Dreiwegehahn zur wahlweisen Schaltung der jeweils leer laufenden Turbine an den Strahler.In the drawing: A mean the compressor for the promotion of the Combustion air, B the turbine to drive the compressor, C the motor to start up the Plant, D the forward turbine, E the reverse turbine, F the common gearbox, H the combustion chamber, I the forward valve, K the reverse valve, L the steam jet to set both turbines under vacuum, M the three-way valve for optional switching of the idling turbine to the emitter.

Die nach dem Anlassen der Anlage durch den Motor C durch den Kompressor A geförderte Brennluft gelangt in die Brennkammer H, von wo die Brenngase geteilt einmal der Kompressorturbine B, zum anderen dem Fahrventil I, K zugeführt werden. Durch Einstellen des jeweils gewünschten Fahrventils I für die Fahrt »Voraus« und K für die Fahrt »Zurück« strömt der abgezweigte Brenngasteil entweder der Vorwärtsturbine D oder der Rückwärtsturbine E zu, die ihre Leistung über das Untersetzungsgetriebe F an die Schraubenwelle abgeben. Zur Verringerung der Leerlaufleistung der jeweils mitgeschleppten Turbine E bzw. D sind beide über das Wechselventil M an den. Dampfstrahler L angeschlossen, so daß die leer laufende Turbine unter Vakuum gesetzt werden kann. Um das Umsteuern des Wechselventils in Abhängigkeit von der Beaufschlagung der Turbinen durch die Fahrventile I und K zu erzwingen, ist das Wechselventil M mit den Fahrventilen entsprechend verblockt.The after starting the system by the engine C by the compressor A conveyed combustion air reaches the combustion chamber H, from where the combustion gases are divided on the one hand to the compressor turbine B and on the other hand to the travel valve I, K. By setting the desired travel valve I for the journey »ahead« and K for the “back” journey, the branched-off fuel gas part flows either from the forward turbine D or the reverse turbine E to which its power via the reduction gear Deliver F to the propeller shaft. To reduce the idle power of each Dragged turbine E and D are both via the shuttle valve M to the. Steam jet L connected so that the idling turbine can be placed under vacuum. To change the direction of the shuttle valve depending on the admission of the turbines To force through the travel valves I and K is the shuttle valve M with the travel valves blocked accordingly.
