Description
Die Erfindung betrifft einen Flüssigkeits-/Dampfkreislauf und ein Dampfkraftwerk mit dem Flüssigkeits-/Dampfkreislauf.The invention relates to a liquid / steam cycle and a steam power plant with the liquid / steam cycle.
In einem Dampfkraftwerk zur Erzeugung von elektrischer Energie wird ein Fluid, insbesondere Wasser, in einem Flüssigkeits-/Dampfkreislauf zirkuliert. Der Flüssigkeits-/Dampfkreislauf weist einen Kessel, eine Dampfturbine und einen Kondensator auf, wobei in dem Kessel unter Zufuhr von Wärmeenergie flüssiges Wasser zu Wasserdampf verdampft wird. Der Wasserdampf wird anschließend in der Dampfturbine entspannt, wobei die Dampfturbine einen elektrischen Generator des Dampfkraftwerks antreibt. Nach dem Austritt des Wasserdampfes aus der Dampfturbine wird der Wasserdampf in dem Kondensator verflüssigt und das dabei entstehende flüssige Wasser wird wieder dem Kessel zugeführt.In a steam power plant for generating electrical energy, a fluid, in particular water, is circulated in a liquid / steam cycle. The liquid / steam cycle comprises a boiler, a steam turbine and a condenser, wherein in the boiler liquid water is vaporized to steam with the supply of heat energy. The steam is then expanded in the steam turbine, wherein the steam turbine drives an electric generator of the steam power plant. After the exit of the steam from the steam turbine, the water vapor is liquefied in the condenser and the resulting liquid water is returned to the boiler.
Um eine Korrosion zu unterbinden, ist es erforderlich, dass sich in dem Flüssigkeits-/Dampfkreislauf nur eine geringe Menge an Sauerstoff befindet. Im Stillstand des Dampfkraftwerkes kommt es jedoch zu einem Einbruch von Luft in den Flüssigkeits-/Dampfkreislauf insbesondere via die Wellendichtungen der Dampfturbine, da diese nicht mehr mit einem Sperrdampf beaufschlagt werden, oder indem bewusst Luft in den Flüssigkeits-/Dampfkreislauf eingeleitet wird. Dabei löst sich der Sauerstoff der Luft in dem flüssigen Wasser bis eine Sättigung des flüssigen Wassers eintritt. Wird das Dampfkraftwerk nach dem Stillstand wieder angefahren, so wird das Dampfkraftwerk herkömmlich in einem Umleitdampfbetrieb betrieben, bei dem die Dampfturbine von dem restlichen Flüssigkeits-/Dampfkreislauf abgekoppelt wird, um einen übermäßigen Kontakt der Dampfturbine mit dem Sauerstoff zu unterbinden. Jedoch ist der restliche Flüssigkeits-/Dampfkreislauf dabei einer hohen Sauerstoffkonzentration und somit einer starken Korrosion ausgesetzt. In dem Umleitdampfbetrieb wird der Sauerstoff in Entgasern oder in dem Kondensator so lange entfernt, bis die Sauerstoffkonzentration in dem Flüssigkeits-/Dampfkreislauf unter einen für die Korrosion unkritischen Grenzwert fällt. Dieser Umleitdampfbetrieb kann mehrere Stunden bis Tage andauern, bei dem die dem Kessel zugeführte Wärmeenergie nicht in elektrische Energie umgesetzt werden kann.To prevent corrosion, it is necessary that there is only a small amount of oxygen in the liquid / steam cycle. At standstill of the steam power plant, however, there is a collapse of air in the liquid / steam cycle in particular via the shaft seals of the steam turbine, as they are no longer subjected to a sealing steam, or by deliberately air is introduced into the liquid / steam cycle. The oxygen in the air dissolves in the liquid water until saturation of the liquid water occurs. If the steam power plant is restarted after a standstill, the steam power plant is conventionally operated in a bypass steam operation, in which the steam turbine is decoupled from the remaining liquid / steam cycle to prevent excessive contact of the steam turbine with the oxygen. However, the remaining liquid / steam cycle is included a high oxygen concentration and thus exposed to strong corrosion. In the bypass steam operation, the oxygen in degasifiers or in the condenser is removed until the oxygen concentration in the liquid / steam cycle falls below a noncritical corrosion limit. This Umleitdampfbetrieb can last several hours to days, in which the boiler supplied heat energy can not be converted into electrical energy.
Aufgabe der Erfindung ist es einen Flüssigkeits-/Dampfkreislauf und ein Dampfkraftwerk mit dem Flüssigkeits-/Dampfkreislauf zu schaffen, wobei der Flüssigkeits-/Dampfkreislauf nach einem Stillstand nur einer geringen Korrosion ausgesetzt ist.The object of the invention is to provide a liquid / steam cycle and a steam power plant with the liquid / steam cycle, wherein the liquid / steam cycle is exposed to a standstill only a small corrosion.
Der erfindungsgemäße Flüssigkeits-/Dampfkreislauf weist einen Kondensator zum Umwandeln eines Dampfs in eine Flüssigkeit und einen Kondensatsammelbehälter zum Auffangen von der in dem Kondensator gebildeten Flüssigkeit auf, wobei der Kondensatsammelbehälter eine Trennwand, die den Kondensatsammelbehälter in eine obere Kammer und eine untere Kammer aufteilt, und eine Kondensatüberlaufleitung auf, via die die Flüssigkeit von der oberen Kammer in die untere Kammer fließbar ist, wobei die untere Kammer derart isolierbar ist, dass kein Fluid in die untere Kammer eintreten kann.The liquid / vapor cycle according to the invention comprises a condenser for converting a vapor into a liquid and a condensate collecting tank for collecting the liquid formed in the condenser, the condensate collecting tank having a partition dividing the condensate collecting tank into an upper chamber and a lower chamber, and a condensate overflow line via which the liquid from the upper chamber in the lower chamber is flowable, wherein the lower chamber is so isolatable that no fluid can enter the lower chamber.
In einem Stillstand des Flüssigkeits-/Dampfkreislaufs kann die untere Kammer derart isoliert werden, dass kein Sauerstoff in die untere Kammer eintreten kann, wodurch auch kein Sauerstoff in der sich in der unteren Kammer befindenden Flüssigkeit gelöst wird. Nach einem Wiederanfahren des Flüssigkeits-/Dampfkreislaufs steht diese sauerstofffreie Flüssigkeit dem Flüssigkeits-/Dampfkreislauf unmittelbar wieder zur Verfügung. Dadurch ist die Sauerstoffkonzentration in dem Flüssigkeits-/Dampfkreislauf nach dem Wiederanfahren gering, wodurch eine Korrosion des Flüssigkeits-/Dampfkreislaufs vorteilhaft unterbunden ist.At a standstill of the liquid / vapor cycle, the lower chamber can be isolated so that no oxygen can enter the lower chamber, thereby also no oxygen is dissolved in the liquid located in the lower chamber. After a restart of the liquid / steam cycle, this oxygen-free liquid is the liquid / steam cycle immediately available again. As a result, the oxygen concentration in the liquid / steam cycle after restarting is low, whereby corrosion of the liquid / steam cycle is advantageously prevented.

Die Trennwand weist bevorzugt ein Gefälle auf und die Kondensatüberlaufleitung mündet im Bereich des unteren Endes des Gefälles in die obere Kammer, so dass die Flüssigkeit mittels des Gefälles der Trennwand in die Kondensatüberlaufleitung leitbar ist. Im Betrieb des Flüssigkeits-/Dampfkreislaufs wird somit die in dem Kondensator entstehende Flüssigkeit zu der Kondensatüberlaufleitung geleitet, von wo sie in die untere Kammer fließt.It is preferred that the condensate overflow line comprises a first shut-off valve, by means of which the lower chamber is isolatable from the upper chamber. The dividing wall preferably has a gradient and the condensate overflow pipe opens in the region of the lower end of the gradient into the upper chamber, so that the liquid can be conducted into the condensate overflow line by means of the gradient of the dividing wall. During operation of the liquid / vapor cycle, the liquid produced in the condenser is thus conducted to the condensate overflow line, from where it flows into the lower chamber.
Bevorzugtermaßen weist der Kondensatsammelbehälter eine Druckausgleichsleitung auf, die die obere Kammer mit der unteren Kammer für einen Druckausgleich der beiden Kammern fluidleitend verbindet. Mittels der Druckausgleichsleitung können Situationen im Betrieb unterbunden werden, in denen sich in der unteren Kammer ein höherer Druck als in der oberen Kammer einstellt, was zu einer Blockierung des Flüssigkeits-/Dampfkreislaufs führen würde. Es ist bevorzugt, dass die Druckausgleichsleitung eine zweite Absperrarmatur aufweist, mittels der die untere Kammer von der oberen Kammer isolierbar ist.Preferred dimensions, the condensate collection on a pressure equalization line, which connects the upper chamber with the lower chamber for pressure equalization of the two chambers fluidly.

It is preferred that the pressure equalization line has a second shut-off valve, by means of which the lower chamber can be isolated from the upper chamber.
Die untere Kammer weist einen sich vertikal erstreckenden Regelbereich auf, innerhalb dessen sich im Betrieb des Flüssigkeits-/Dampfkreislaufs der Pegel der Flüssigkeit befindet. Es ist bevorzugt, dass die Druckausgleichsleitung oberhalb des Regelbereichs in die untere Kammer mündet. Dadurch ist vorteilhaft sichergestellt, dass im Betrieb des Flüssigkeits-/Dampfkreislaufs keine Flüssigkeit via die Druckausgleichsleitung von der unteren Kammer in die obere Kammer fließen kann und dass die Druckausgleichung keine Beeinträchtigung ihrer Funktion durch die Flüssigkeit erfährt.The lower chamber has a vertically extending control range within which the liquid level is located during operation of the liquid / vapor cycle. It is preferred that the pressure equalization line opens above the control range in the lower chamber. This advantageously ensures that during operation of the liquid / vapor cycle no liquid can flow via the pressure equalization line from the lower chamber into the upper chamber and that the pressure equalization does not experience any impairment of its function by the liquid.
Bevorzugtermaßen weist der Flüssigkeits-/Dampfkreislauf eine an die untere Kammer angeschlossene Kondensatleitung auf, via die die Flüssigkeit von der unteren Kammer weg transportierbar ist, wobei die Kondensatleitung eine dritte Absperrarmatur aufweist, mittels der die untere Kammer isolierbar ist.Preferably, the liquid / vapor circuit has a condensate line connected to the lower chamber via which the liquid can be transported away from the lower chamber is, wherein the condensate line has a third shut-off valve, by means of which the lower chamber is isolable.

Das Dampfkraftwerk hat den Vorteil, dass nach einem Stillstand des Dampfkraftwerks die Dauer eines Umleitdampfbetriebs, bei dem der Sauerstoff aus dem Flüssigkeits-/Dampfkreislauf entfernt wird und das Dampfkraftwerk keine elektrische Energie erzeugen kann, kurz ist oder gar vollständig vermieden werden kann.The steam power plant according to the invention has the liquid / steam cycle according to the invention.
