Description

Die Erfindung bezieht sich auf Kolbendampfmaschinen-Abdampfturbinenanlagen zum Antrieb von Schiffen mxt wahlweiser Boawfschlagung derAbdampfturbine mit gedrosseltem Frischdampf. Man hat .die Beaufschlagung der Abdampfturbne mit gedrosseltem Frischdampf vorgeschlagen, um ,das Schiff bei havarierter Kolbenmaschine bewegungsfähig halten zu können. Die Einführung von gedrosseltem Frischdampf unmittelbar in die Abdampfturbine ist aber ohne Schäden für die Anlage nicht möglich, da der Dampf auch nach der Drosselung eine Temperatur behält, die nur wenig unter der Frischdampftemperatur liegt. Es entstehen sonach. in der Turbine und im Kondensator Wärme spannungen, die in der Turbine zum Verziehen des Läufers, Streifen der Schaufeln und Undichtigkeiten an den Stopfbüchsen, im Kondensator zum Verziehen der Rohre und Undichtwerden der Verschraubungen führen. Außerdem wird wegen der .größeren abzuführenden Wärmemenge das Vakuum im Kondensator schlechter, was zu einer erheblichen Leistungsminderung führt. Es ist bei Landanlagen an sich bekannt, gedrosselten Frischdampf durch Kühlung angenähert auf den Zustand des Dampfes einer Nachschaltdumpfmaschine zu bringen; die bekannten Einrichtungen eignen sich .aber nicht ohne weiteres, um gedrosselten Frischdampf einer Kolbendampfmaschin.en-Abdampfturbinenanlage auf den Zustand,des Abdampfes der letzten Expansionsstufe der Kolbendampfmaschine zu bringen. Die Erfindung bezweckt die Schaffung einer Kolben-.dampf maschinen-Abidampfturbinenanlage, in,der idie Abdumpfturbine bei havarierter Kolbenmaschine ohne Gefähr!dungder Anlage wahlweise mit Frischdampf beauf.schlugt werden kann.The invention relates to piston steam engine exhaust turbine systems for propulsion of ships with optional Boawfschlagung derAbdampfturbine with throttled Live steam. One has .the application of the exhaust steam turbine with throttled live steam proposed to keep the ship mobile in the event of a wrecked piston engine to be able to. The introduction of throttled live steam directly into the exhaust steam turbine However, this is not possible without damage to the system, as the steam continues after the throttling maintains a temperature that is only slightly below the live steam temperature. It arise accordingly. in the turbine and in the condenser heat tensions in the Turbine to warp the rotor, streaking the blades and leaks the stuffing boxes, in the condenser to warp the pipes and leak in the screw connections to lead. In addition, the vacuum in the Capacitor worse, which leads to a significant reduction in performance. It is known per se in land systems, throttled live steam approximated by cooling to bring to the state of the steam of a rear-mounted dump machine; the known Facilities are, but not necessarily, suitable for circulating live steam a Kolbendampfmaschin.en exhaust steam turbine system on the condition of the exhaust steam to bring the last expansion stage of the piston steam engine. The invention aims the creation of a piston-steam engine-abi-steam turbine plant, in, the idie Optional exhaust turbine with a damaged piston engine without endangering the system can be exposed to live steam.

Zu diesem Zweck wird gemäß der Erfindung der zur Beaufschlagung .dienende Frischdampf einem Behälter mit Entspannungsdüse für den Frischdampf und gleichachsig mit dieser in Gegenüberstellung angeordneter Zerstäuberdüse für das Kühlwasser zugeführt. Dem mit hoher Geschwindigkeit aus der Entspannungsdüse strömenden Frischdampf wird durch die regelbare Einspritzdüse für das Kühlwasser ein Strahl fein zerstäubten Wassers mit großer Geschwindigkeit entgegengespritzt. Beide vermischen sich unter Verdampfung des Wassers zu einem N aß,dampf mit annähernd dem Zustand des Abdampfes vor der Abd@ampfturbine. Die Entspannungsdüse und: die Einspritzdüse sind dabei außermittig in den Entspannungsbehälter eingeführt, und das Überleitungsrohr für die Zuführung des entspannten und. gekühlten Frischdampfes zur Turbine ist in den so gebildeten freien Raum des Behälters verlängert. Der entspannte und gekühlte Dampf tritt jetzt nach mehrmaligem Richtungswechsel durch .einen Siebaufsatz in das Austrittsrohr zur Turbine ein, das an die Überströmleitung von .der Kolbendampfmaschine zur Turbine angeschlossen ist. Das Kühlwasser wird. zweckmäßig der Speisewasserdruckleitun.g entnommenaund das nicht verdampfte Wasser der Entwässerungsleitung zum Kondensator zugeführt.For this purpose, according to the invention, the .dienende for loading Live steam a container with an expansion nozzle for the live steam and equiaxed supplied with this in opposition arranged atomizer nozzle for the cooling water. The live steam flowing out of the expansion nozzle at high speed becomes finely atomized a jet through the adjustable injection nozzle for the cooling water Water sprayed against it at great speed. Both mix in Evaporation of the water to a wet, vapor with approximately the state of the evaporation in front of the Abd @ ampfturbine. The relaxation nozzle and: the injection nozzle are included introduced off-center into the expansion tank, and the transfer pipe for the feeding of the relaxed and. cooled live steam to the turbine is in the thus formed free space of the container is extended. The relaxed and chilled one After changing direction several times, steam now passes through a sieve attachment in the outlet pipe to the turbine, which is connected to the overflow line from the piston steam engine connected to the turbine. The cooling water is. appropriately the feed water pressure line and the non-evaporated water from the drainage line to the condenser fed.

Die Zeichnung zeigt ein Ausführungsbeispiel im Vertikalschnitt.The drawing shows an embodiment in vertical section.

In den Entspannungsbehälter i mündet das koiiische Verlängerungsrohr 2 der Entspannungsdüse 3. Gleichachsig mit der Entspannungsdüse 3 ist der regelbare Zerstäuber 5 für das Kühlwasser in Gegenüberstellung angeordnet. Er besteht aus der Einspritzdüse 6 für das Kühlwasser und dem der Düse 6 vorgeschalteten regelbaren Nadelventil 7, das durch das Handrad 8 verstellt wird. Sowohl die Entspannungsdüse 3 als auch die Einspritzdüse 6 sind im Behälter i außermittig angeordnet. In dem so geschaffenen. freien Raum im Behälter i ist das in den Behälter i verlängerte, mit dem Siebaufsatz io versehene Zuleitungsrohr 9 zur Turbine angeordnet, so daß :der aus der Düse 3 gekühlt und entspannt austretende Frischdampf seine Richtung mehrmals ändern muß, um aus dem Behälter i zur Turbine überströmen zu können. Die Entwässerungsleitung ii dient zum Überführen des zuviel eingespritzten Wassers- zum Kondensator.The expansion tube 2 of the expansion nozzle 3 opens into the expansion tank i. Coaxially with the expansion nozzle 3, the controllable atomizer 5 for the cooling water is arranged opposite one another. It consists of the injection nozzle 6 for the cooling water and the adjustable needle valve 7 connected upstream of the nozzle 6, which is adjusted by the handwheel 8. Both the expansion nozzle 3 and the injection nozzle 6 are arranged eccentrically in the container i. In the one created in this way. Free space in the container i is the extended into the container i, provided with the sieve attachment io feed pipe 9 to the turbine, so that: the cooled and relaxed live steam emerging from the nozzle 3 has to change its direction several times in order to move from the container i to the turbine to be able to overflow. The drainage line ii serves to transfer the excessively injected water to the condenser.
