Description

Die Erfindung betrifft eine Dampfkraftanlage zur Erzeugung elektrischer Energie umfassend eine Dampfturbine, einen Dampferzeuger und einen Kondensator sowie eine Frischdampfrohrleitung, die die Dampfturbine mit dem Dampferzeuger strömungstechnisch miteinander verbindet, einer Abdampfrohrleitung, die die Dampfturbine mit dem Kondensator strömungstechnisch miteinander verbindet und einer Umleitrohrleitung, die die Frischdampfrohrleitung mit der Abdampfrohrleitung strömungstechnisch miteinander verbindet.The invention relates to a steam power plant for generating electrical energy comprising a steam turbine, a steam generator and a condenser and a live steam pipe, which fluidly connects the steam turbine to the steam generator, a Abdampfrohrleitung which fluidly connects the steam turbine to the condenser and a Umleitrohrleitung, the Fresh steam pipe with the exhaust steam pipe fluidly connects together.

Eine solche Dampfkraftanlage ist z.B in Dokumenten DE 102 27 709 A1 und US 6 457 313 B1 offenbart.Such a steam power plant is eg in documents DE 102 27 709 A1 and US 6,457,313 B1 disclosed.

In einer Dampfkraftanlage wird Wärmeenergie in mechanische Energie und schließlich in elektrische Energie umgewandelt, wobei Wasserdampf vom Dampferzeuger in eine Expansionsmaschine wie z.B. einer Dampfturbine strömt, wobei sich der Dampf in der Dampfturbine unter Arbeitsabgabe entspannt. Der aus der Dampfturbine ausströmende Dampf wird in einem nachgeschalteten Kondensator durch Wärmeentzug wieder verflüssigt. Das im Kondensator entstehende Wasser wird von einer Speisewasserpumpe wieder zum Dampferzeuger gefördert, wodurch ein geschlossener Kreislauf entsteht.In a steam power plant, heat energy is converted into mechanical energy and finally into electrical energy, whereby steam from the steam generator is fed into an expansion machine, such as a steam generator. a steam turbine flows, whereby the steam in the steam turbine relaxes under work output. The effluent from the steam turbine steam is liquefied in a downstream condenser by removing heat. The resulting water in the condenser is fed by a feedwater pump back to the steam generator, creating a closed circuit.

Im Betriebszustand strömt der aus dem Dampferzeuger strömende Dampf in die Dampfturbine und kühlt sich hierbei ab, wobei der Dampfdruck abnimmt. Der aus der Dampfturbine ausströmende Dampf wird dem Kondensator zugeleitet. Beim Anfahren, Abfahren oder bei einem Dampfturbinenschnellschluss wird ein vor der Dampfturbine angeordnetes Frischdampfventil geschlossen und der Frischdampf über eine Umleitrohrleitung geleitet, wobei die Umleitrohrleitung in eine Abdampfrohrleitung der Dampfturbine mündet. Die Abdampfrohrleitung wird in der Regel als kalte Zwischenüberhitzerleitung bezeichnet, sofern diese in einen Zwischenüberhitzer mündet, in dem der Dampf auf eine höhere Temperatur erhitzt wird. Je höher die Dampftemperaturen sind, desto höher sind die Kosten für die Rohrleitungen, Umleitstationen und der Umleitdampfeinspritzung zum Kondensator. Es werden Bestrebungen unternommen, Dampftemperaturen von ca. 720°C zu erreichen. Solch hohe Temperaturen erfordern den Einsatz von besonderen Werkstoffen, wie z.B. Werkstoffe aus Nickelbasis. Werkstoffe aus Nickelbasis sind Werkstoffe mit einem Nickelgehalt von ca. 40 bis 50 Gew.-%. Allerdings sind solche Werkstoffe aus Nickelbasis vergleichweise teuer. Auf der anderen Seite ist ein Werkstoff aus Nickelbasis thermisch besonders belastbar.In the operating state, the steam flowing out of the steam generator flows into the steam turbine and cools down, the vapor pressure decreasing. The effluent steam from the steam turbine is fed to the condenser. During startup, shutdown or during a steam turbine fast closing, a live steam valve arranged in front of the steam turbine is closed and the live steam is conducted via a bypass pipe, the bypass pipe leading into an exhaust steam pipe of the steam turbine. The Abdampfrohrleitung is usually referred to as a cold reheater line, if it opens into a reheater in which the steam is heated to a higher temperature. The higher the steam temperatures are, the higher the cost of the piping, bypass stations and the Umleitdampfeinspritzung to the condenser. Efforts are being made to achieve steam temperatures of about 720 ° C. Such high temperatures require the use of special materials, such as nickel-based materials. Materials made of nickel are materials with a nickel content of about 40 to 50 wt .-%. However, such nickel base materials are comparatively expensive. On the other hand, a material made of nickel-based is particularly resilient thermally.

Wünschenswert wäre es, Werkstoffe einsetzen zu können, die günstiger sind als Werkstoffe aus Nickelbasis. An dieser Stelle setzt die Erfindung an, deren Aufgabe es ist, eine Dampfkraftanlage anzugeben, die für hohe Temperaturen geeignet ist und vergleichsweise günstig ausgebildet werden kann.It would be desirable to be able to use materials that are cheaper than nickel-based materials. At this point, the invention begins, whose task is to provide a steam power plant, which is suitable for high temperatures and can be formed comparatively low.

Gelöst wird diese Aufgabe durch eine Dampfkraftanlage zur Erzeugung elektrischer Energie gemäß unabhängigen Anspruch 1.This object is achieved by a steam power plant for generating electrical energy according to independent claim 1.

Durch die Kühlung des Dampfes mit dem Umleitdampfkühler können die Komponenten hinter der Kühlung ohne Nickelbasis-Werkstoffe ausgeführt werden. Die nach dem Umleitdampfkühler angeordnete Rohrleitung wird somit gekühlt, was dazu führt, dass die Umleitrohrleitung weniger thermisch beansprucht wird. Durch die geringere thermische Beanspruchung, ist es nun nicht mehr erforderlich, teure Werkstoffe aus Nickelbasis zu verwenden.By cooling the steam with the bypass steam cooler, the components behind the cooling can be carried out without nickel-based materials. The arranged after the bypass steam cooler pipe is thus cooled, which causes the Umleitrohrleitung is less thermally stressed. Due to the lower thermal stress, it is no longer necessary to use expensive nickel-based materials.

Dabei wird der Umleitdampfkühler unmittelbar nach einem ersten Abzweig von der Frischdampfrohrleitung zur Umleitrohrleitung angeordnet. Idealerweise sollte der Umleit- dampfkühler so nah wie möglich nach dem ersten Abzweig angeordnet werden. Dies hat den Vorteil, dass die Kosten für die Herstellung der Dampfkraftanlage weiter verringert werden können, denn die Verwendung von teurem Nickelbasiswerkstoff wird vermieden. Je näher der Umleitdampfkühler an dem ersten Abzweig von der Frischdampfrohrleitung zur Umleitrohrleitung angebracht wird, umso weniger Nickelbasiswerkstoff wird zwischen dem ersten Abzweig zum Umleitdampfkühler benötigt.In this case, the bypass steam cooler is arranged immediately after a first branch from the live steam pipe to Umleitrohrleitung. Ideally, the bypass steam cooler should be placed as close to the first branch as possible. This has the advantage that the costs for the production of the steam power plant can be further reduced because the use of expensive nickel base material is avoided. The closer the bypass steam cooler is mounted to the first branch from the live steam piping to the bypass piping, the less nickel base material is needed between the first branch to the bypass steam cooler.

Sofern die Abdampfrohrleitung in einen Zwischenüberhitzer mündet, wird diese auch als kalte Zwischenüberhitzerleitung bezeichnet. Im Zwischenüberhitzer wird Dampf auf eine höhere Temperatur erhitzt.If the Abdampfrohrleitung opens into a reheater, this is also referred to as a cold reheater line. In the reheater, steam is heated to a higher temperature.

Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.Advantageous developments are specified in the subclaims.

So ist es vorteilhaft, wenn die Kühlung des Dampfes im Umleitdampfkühler durch Eindüsen von Kühlmedium wie Kondensat, Dampf oder einer Mischung aus Wasser und Dampf erfolgt. Die Verwendung von Kondensat, oder einer Mischung aus Wasser und Dampf ist in einer Dampfkraftanlage vergleichsweise einfach, da diese Kühlmedien in einer Dampfkraftanlage zur Verfügung stehen. Der Einsatz von zusätzlichen Rohrleitungen wird dadurch minimiert.Thus, it is advantageous if the cooling of the steam takes place in the bypass steam cooler by injecting cooling medium such as condensate, steam or a mixture of water and steam. The use of condensate, or a mixture of water and steam is comparatively easy in a steam power plant, since these cooling media are available in a steam power plant. The use of additional piping is thereby minimized.

In einer weiteren vorteilhaften Weiterbildung ist der Abstand zwischen dem Umleitdampfkühler und dem Hochdruck-Umleitventil derart gewählt, dass sich das Kühlmedium mit dem Dampf vollständig vermischt.In a further advantageous development, the distance between the bypass steam cooler and the high-pressure bypass valve is selected such that the cooling medium is completely mixed with the steam.

Eine vollständige Vermischung des Kühlmediums mit dem Dampf führt zu einer effizienten Kühlung der Umleitrohrleitung und dadurch zu einer weiteren Verringerung der Kosten bei der Herstellung der Dampfkraftanlage, da weniger Nickelbasiswerkstoff für die Umleitrohrleitung verwendet werden kann. Die Erfindung wird beispielhaft anhand der Zeichnungen näher erläutert.A complete mixing of the cooling medium with the steam leads to an efficient cooling of Umleitrohrleitung and thereby to a further reduction in costs Production of the steam power plant, as less nickel base material can be used for the diversion pipeline. The invention will be explained in more detail by way of example with reference to the drawings.

Die Figur 1 zeigt eine Dampfkraftanlage 1 gemäß dem Stand der Technik. Die Dampfkraftanlage 1 umfasst einen Dampferzeuger 2, eine Dampfturbine 3, wobei die Dampfturbine 3 eine Hochdruck-Teilturbine 3a, Mitteldruck-Teilturbine 3b und Niederdruck-Teilturbine 3c umfasst sowie einem Kondensator 4. Des Weiteren ist eine Frischdampfrohrleitung 5 vorgesehen, die die Dampfturbine 3 mit dem Dampferzeuger 2 strömungstechnisch miteinander verbindet. Nach der Dampfturbine 3 ist eine Abdampfrohrleitung 6 angeordnet, die die Dampfturbine 3 mit dem Kondensator 4 strömungstechnisch miteinander verbindet. Zwischen der Hochdruck-Teilturbine 3a und dem Kondensator 4 ist ein Zwischenüberhitzer 7 vorgesehen. Der in den Zwischenüberhitzer 7 einströmende Dampf wird auf eine höhere Temperatur erhitzt und über eine heiße Zwischenüberhitzerleitung 8 zu der Mitteldruck-Teilturbine 3b geführt. Die Abdampfrohrleitung 6 kann auch als kalte Zwischenüberhitzerleitung 9 bezeichnet werden. Vor der Dampfturbine 3 ist ein Schnellschluss- und Regelventil 10 angeordnet. Vor der Mitteldruck-Teilturbine 3b ist ebenso ein Schnellschluss- und Regelventil 11 angeordnet. Die Frischdampfrohrleitung 5 ist mit der Abdampfrohrleitung 6 bzw. der kalten Zwischenüberhitzerleitung 9 strömungstechnisch über eine Umleitrohrleitung 12 verbunden. In der Umleitrohrleitung 12 ist ein Hochdruck-Umleitventil 13 angeordnet.The FIG. 1 shows a steam power plant 1 according to the prior art. The steam power plant 1 comprises a steam generator 2, a steam turbine 3, wherein the steam turbine 3 comprises a high-pressure turbine section 3a, medium-pressure turbine section 3b and low-pressure turbine section 3c and a condenser 4. Furthermore, a live steam pipe 5 is provided, which the steam turbine 3 with the steam generator 2 fluidly connects to each other. After the steam turbine 3, a Abdampfrohrleitung 6 is arranged, which connects the steam turbine 3 with the condenser 4 fluidly. Between the high-pressure turbine part 3a and the condenser 4, a reheater 7 is provided. The steam flowing into the reheater 7 is heated to a higher temperature and conducted via a hot reheater line 8 to the medium-pressure turbine section 3b. The Abdampfrohrleitung 6 can also be referred to as a cold reheater line 9. In front of the steam turbine 3, a quick-closing and control valve 10 is arranged. Before the medium-pressure turbine section 3b, a quick-closing and control valve 11 is also arranged. The live steam pipe 5 is fluidly connected to the exhaust steam pipe 6 and the cold reheater pipe 9 via a Umleitrohrleitung 12. In the Umleitrohrleitung 12 a high-pressure diverter valve 13 is arranged.

Die heiße Zwischenüberhitzerleitung 8 ist mit dem Kondensator 4 über eine Mitteldruck-Umleitrohrleitung 14 strömungstechnisch miteinander verbunden. In der Mitteldruck-Umleitrohrleitung 14 ist ein Mitteldruck-Umleitventil 17 angeordnet. Beim Anfahren, Abfahren oder bei einem Turbinenschnellschluss der Dampfturbine 3 wird der Dampf von der Frischdampfrohrleitung 5 über die Umleitrohrleitung 12 in die kalte Zwischenüberhitzerrohrleitung 9 geleitet. Dazu wird das Schnellschluss- und Regelventil 10 geschlossen und das Hochdruck-Umleitventil 13 geöffnet. Da die Temperatur des in die Umleitrohrleitung 12 strömenden Frischdampfes vergleichsweise hoch ist, wird vor Eintritt in die kalte Zwischenüberhitzerrohrleitung 9 der Dampf mit einem Kühlmedium 15 in einer Kühleinheit 16 abgespritzt. Der Dampf wird anschließend über den Zwischenüberhitzer 7, der heißen Zwischenüberhitzerleitung 8 zur Mitteldruck-Umleitrohrleitung 14 in den Kondensator 4 geführt. Dazu wird das Schnellschluss- und Regelventil 11 geschlossen und das Mitteldruck-Umleitventil 17 geöffnet. Nach dem Mitteldruck-Umleitventil 17 wird der Dampf wiederum mit einem Kühlmedium 18 in einer Kühleinheit 19 abgespritzt, damit der Kondensator die Energiemengen aufnehmen kann. Da die Temperaturen und der Druck des Dampfes vergleichsweise hoch sind, müssen die Frischdampfrohrleitung 5, die Umleitrohrleitung 12, die heiße Zwischenüberhitzerleitung 9 und die Mitteldruck-Umleitrohrleitung 14 für den Druck und die Temperatur des Zwischenüberhitzers 7 ausgelegt werden. Je höher die Dampftemperaturen sind, desto höher sind die Kosten für die Rohrleitungen 5, 12, 9, 8, 1, für die Ventile 17, 13 und die Kühleinheiten 16 und 19.The hot reheater line 8 is fluidically connected to the condenser 4 via a medium-pressure Umleitrohrleitung 14. In the medium-pressure Umleitrohrleitung 14 a medium-pressure diverter valve 17 is arranged. During start-up, shut-down or during a turbine quick-closing of the steam turbine 3, the steam is conducted from the live steam pipe 5 via the bypass pipe 12 into the cold reheater pipe 9. For this purpose, the quick-closing and control valve 10 is closed and the high-pressure diverter valve 13 is opened. Since the temperature of the live steam flowing into the bypass pipe 12 is comparatively high, the steam is sprayed with a cooling medium 15 in a cooling unit 16 before entering the cold reheater pipe 9. The steam is then passed through the reheater 7, the hot reheater line 8 to the medium-pressure Umleitrohrleitung 14 in the condenser 4. For this purpose, the quick-closing and control valve 11 is closed and the medium-pressure diverter valve 17 is opened. After the medium-pressure diverter valve 17, the steam is in turn injected with a cooling medium 18 in a cooling unit 19, so that the capacitor can absorb the amounts of energy. Since the temperatures and the pressure of the steam are comparatively high, the live steam pipe 5, the bypass pipe 12, the hot reheater pipe 9 and the medium pressure bypass pipe 14 must be designed for the pressure and the temperature of the reheater 7. The higher the steam temperatures are, the higher are the costs for the pipelines 5, 12, 9, 8, 1, for the valves 17, 13 and the cooling units 16 and 19.

In der Figur 2 ist eine erfindungsgemäße Dampfkraftanlage 1 dargestellt. Der Unterschied zu der in Figur 1 dargestellten Dampfkraftanlage 1 besteht darin, dass in der Umleitrohrleitung 12 und in der Mitteldruck-Umleitrohrleitung 14 ein Umleitdampfkühler 20 bzw. ein Mitteldruck-Umleitdampfkühler 21 angeordnet sind. Der Umleitdampfkühler 20 und der Mitteldruck-Umleitdampfkühler 21 sind zum kühlen eines in der Umleitrohrleitung 12 und der Mitteldruck-Umleitrohrleitung 14 befindlichen strömbaren oder stehenden Dampfes ausgebildet. Mittels des Umleitdampfkühlers 20 und des Mitteldruck-Umleitdampfkühlers 21 wird Kondensat, Dampf oder ein Gemisch aus Wasser und Dampf in den strömenden oder stehenden Dampf eingespritzt. Somit wird die Temperatur des strömenden oder stehenden Dampfes verringert. Das in den Dampf zugeführte Kühlmedium 22 kühlt somit den Dampf ab. Die Eindüsung des Kühlmediums 22 in die Umleitrohrleitung 12, und in die Mitteldruck-Umleitrohrleitung 14 sollte möglichst nah an einem ersten Abzweig 23 bzw. nach einem zweiten Abzweig 24 angeordnet werden. Der Abstand zwischen dem Umleitdampfkühler 20 und dem Hochdruck-Umleitventil 13 wird derart gewählt, dass der Dampf mit dem Kühlmedium 22 vollständig vermischt wird. Ebenso wird der Abstand zwischen dem Mitteldruck-Umleitdampfkühler 21 und dem Mitteldruck-Umleitventil 17 derart gewählt, dass der Dampf mit dem Kühlmedium 22 vollständig vermischt werden kann.In the FIG. 2 a steam power plant 1 according to the invention is shown. The difference to the in FIG. 1 illustrated steam power plant 1 is that in the Umleitrohrleitung 12 and in the medium-pressure Umleitrohrleitung 14 a Umleitdampfkühler 20 and a medium-pressure Umleitdampfkühler 21 are arranged. The bypass steam cooler 20 and the medium pressure bypass steam cooler 21 are for cooling one in the bypass pipe 12 and the medium-pressure Umleitrohrleitung 14 located flowable or stationary steam formed. By means of the bypass steam cooler 20 and the medium-pressure bypass steam cooler 21, condensate, steam or a mixture of water and steam is injected into the flowing or standing steam. Thus, the temperature of the flowing or standing steam is reduced. The supplied into the steam cooling medium 22 thus cools the steam. The injection of the cooling medium 22 into the Umleitrohrleitung 12, and in the medium-pressure Umleitrohrleitung 14 should be as close to a first branch 23 and after a second branch 24 are arranged. The distance between the bypass steam cooler 20 and the high-pressure bypass valve 13 is selected such that the steam is completely mixed with the cooling medium 22. Likewise, the distance between the medium-pressure Umleitdampfkühler 21 and the medium-pressure diverter valve 17 is selected such that the steam with the cooling medium 22 can be completely mixed.

Evtl. kann auf die Kühleinheit 16 bzw. 19 verzichtet werden, wenn die Frischdampfparameter entsprechende Werte aufweisen. Dafür müssen der Frischdampfmassenstrom, -druck und -temperatur, Wassereinspritzmenge und Temperatur zulässige Werte aufweisen. Der Umleitdampfkühler 20 und der Mitteldruck-Umleitdampfkühler 21 werden sobald das Umleitventil 13 und das Mitteldruck-Umleitventil 17 geöffnet ist, eingeschaltet. Dadurch wird eine unzulässige Temperaturüberschreitung in der gekühlten Umleitrohrleitung 25 bzw. 26 wirksam vermieden.Possibly. can be dispensed with the cooling unit 16 and 19, if the live steam parameters have corresponding values. For this, the live steam mass flow, pressure and temperature, water injection quantity and temperature must have permissible values. The bypass steam cooler 20 and the medium-pressure bypass steam cooler 21 are switched on as soon as the bypass valve 13 and the medium-pressure bypass valve 17 are opened. As a result, an inadmissible temperature exceeded in the cooled Umleitrohrleitung 25 and 26 effectively avoided.

Sobald das Umleitventil 13 geschlossen wird, wird der Umleitdampfkühler 20 so lange betrieben, bis die Temperaturen vor dem Umleitdampfkühler 20 die zulässige Temperatur in den Rohrleitungen 25 unterschreitet. Sofern Entwässerungen oder Anwärmleitungen in den gekühlten Umleitrohrleitungen 25 und 26 angeordnet sind, müssen diese so lange geschlossen bleiben, bis die Temperatur vor dem Umleitdampfkühler 20 und Mitteldruck-Umleitdampfkühler 21 die zulässige Temperatur in den gekühlten Rohrleitungen 25 bzw. 26 unterschreitet.As soon as the bypass valve 13 is closed, the bypass steam cooler 20 is operated until the temperatures before the bypass steam cooler 20 fall below the permissible temperature in the pipelines 25. If drainages or Anwärmleitungen are arranged in the cooled Umleitrohrleitungen 25 and 26, they must remain closed until the temperature before Umleitdampfkühler 20 and medium-pressure Umleitdampfkühler 21 below the allowable temperature in the cooled pipes 25 and 26 respectively.
