Description

Dampfkraftanlage mit Pumpspeicherwerk Es ist bekannt, Kraftwerke zur Erhöhung der Leistungsfähigkeit mit Pumpspeicheranlagen zu versehen, bei denen zu Zeiten geringer Leistung eine von der Kraftmaschine angetriebene Pumpe Wasser in einen Hochbehälter fördert, dessen Druckgefälle zu Zeiten stärkerer Belastung in einer Wasserturbine ausgenutzt wird. Das Neue der Erfindung besteht nun darin, das in den Hochbehälter zu fördernde Wasser vorher durch Abdampf der Kraftmaschine aufzuheizen und nach Ausnutzung seines Druckgefälles in Verdampferanlagen zum Betriebe von Abdampfturbinen zum Teil zu verdampfen.Steam power plant with pumped storage plant It is known to power plants Increase the efficiency with pumped storage systems, where too Times of low power a pump driven by the prime mover water in promotes an elevated tank, the pressure gradient of which at times of greater stress in a water turbine is used. The novelty of the invention is that Heat up water to be pumped into the elevated tank beforehand by means of exhaust steam from the engine and after utilizing its pressure drop in evaporator systems to operate exhaust steam turbines to partially evaporate.

In der Zeichnung ist die Erfindung schematisch veranschaulicht. Von dem Kessel ro wird eine mit einem Stromerzeuger z z gekuppelte Gegendruckmaschine 12 versorgt, deren Abdampf während der geringeren Belastungszeit der Anlage »in den Vorwärmer 13 strömt und das von dem unteren Behälter 1q. durch eine mit der Gegendruckmaschine-r2 bei 15 gekuppelte Pumpe 16 in den oberen Speicherbehälter 17 gepumpte Wasser erwärmt.The invention is illustrated schematically in the drawing. from the boiler ro is a counterpressure machine coupled to a power generator z z 12, whose exhaust steam during the lower load period of the system »in the preheater 13 flows and that of the lower container 1q. through one with the Counter-pressure machine-r2 at 15 coupled pump 16 in the upper storage tank 17 pumped water is heated.

Das in dem Behälter 17 aufgespeicherte vorgewärmte Wasser gibt seine durch das Druckgefälle erzeugte Energie an eine Wasserturbine 18 ab, die mit einem Stromerzeuger z9 gekuppelt ist. Das die Turbine 18 antreibende Wässer fließt dann in einen Verdampfer 2o, wo es zum Teil verdampft und in einer mit einem weiteren Stromerzeuger 21 gekuppelten Niederdruckturbine 22 ausgenutzt wird. Der Abdampf dieser Niederdruckturbine 22 gelangt dann in einen Kondensator 23.The accumulated in the container 1 7 preheated water transfers its generated by the pressure gradient energy to a water turbine 18 that is coupled to a current generator z9. The water driving the turbine 18 then flows into an evaporator 2o, where it partially evaporates and is used in a low-pressure turbine 22 coupled to a further power generator 21. The exhaust steam from this low-pressure turbine 22 then passes into a condenser 23.

Der Betrieb bei geringer Belastung der Anlage ergibt sich aus der vorstehenden Schilderung. Bei auftretender Spitzenbelastung wird die Pumpe 16 durch Lösung der Kupplung 15 stillgesetzt und der Abdampf der Gegendruckmaschine 12 nicht in den Vorwärmer 13 geleitet, sondern in eine der Niederdruckturbine 22 vorgeschaltete Stufe 2q..Operation with a low load on the system results from the description above. In the event of a peak load, the pump 1 6 is stopped by releasing the clutch 1 5 and the exhaust steam from the counter-pressure machine 12 is not directed into the preheater 13, but into a stage 2q upstream of the low-pressure turbine 22.

Die Reibungswärme der Pumpe und der Wasserturbine wird auch ausgenutzt, indem sich dadurch die Wassertemperatur, wenn auch nur sehr wenig, erhöht und somit eine etwas größere Dampferzeugung im Verdampfer erzielt.The frictional heat of the pump and the water turbine is also used, by increasing the water temperature, albeit very little, and thus a slightly larger amount of steam is generated in the evaporator.

Bei diesen Anlagen werden zweckmäßig die Speicherbehälter geschlossen ausgeführt, um den Zutritt von Sauerstoff in das Speicherwasser zu vermeiden und um das Wasser auf mehr als roo° vorwärmen zu können.In these systems, the storage tanks are expediently closed designed to prevent oxygen from entering the storage tank water and in order to be able to preheat the water to more than roo °.

Das aus der Verdampferanlage 2o abfließende Wasser kann zu Kesselspeisezwecken verwendet werden, da bei Abschluß der Behälter Kondensat als Speicherflüssigkeit genommen werden kann und die Temperatur dieses Wassers noch immer verhältnismäßig hoch ist.The water flowing out of the evaporator system 2o can be used for boiler feeding purposes can be used, since condensate is used as storage liquid when the container is closed can be taken and the temperature of this water is still proportionate is high.
