Description

Technisches GebietTechnical field

Die Erfindung betrifft ein Dampfkraftwerk, im wesentlichen bestehend aus einem Dampferzeuger, einer Turbogruppe mit Kondensationsdampfturbine und Generator, einem wassergekühlten Kondensator und einer anzapfdampfbeheizten Vorwärmeranlage.The invention relates to a steam power plant, consisting essentially of a Steam generator, a turbo group with a condensation steam turbine and generator, a water-cooled condenser and a preheater system heated by tap steam.

Stand der TechnikState of the art

Derartige Kraftwerke werden in der Regel nach Kundenspezifikation und Standortanforderungen gefertigt und weisen daher lange Zeiten für Projektentwicklung, -planung und Bau und damit verbunden hohe Kosten auf. Vor allem die Bauzeit wird bei diesen an Kundenspezifikationen orientierten Kraftwerken von der Tatsache beeinflußt, daß ein möglichst detailliertes Vorab-Engineering nicht möglich ist und wesentliche Arbeiten, wie z.B. der Bauteil, welche möglichst früh bearbeitet werden sollten, erst mit Verzögerung angegangen werden können.Such power plants are usually built according to customer specifications and site requirements manufactured and therefore have long times for project development, -planning and construction and associated high costs. Especially the construction period in these power plants, which are oriented towards customer specifications, the fact influences that the most detailed preliminary engineering possible is not possible and essential work, such as the component that processes as early as possible should only be tackled with a delay.

Es ist an sich bekannt, durch die Einrichtung von Kraftwerken in Freiluftbauweise die Bauzeit zu verkürzen. Allerdings bedingt diese Bauweise wiederum ein Reihe von Nachteilen im Hinblick auf deren Betrieb sowie deren Wartung und Reparatur. In diesem Zusammenhang offenbaren DE 1426918 A1 und BE 669251 das Konzept eines Dampfkraftwerks, das in verkürzter Bauzeit und mit verringerten Investitionskosten erstellt und dabei die besagten Nachteile vermindern soll. Dieses Konzept beruht im wesentlichen darauf, dass der Turbosatz in einer Gasse zwischen den Dampferzeugern angeordnet ist und ein Portalkran auf den Dampferzeugern montiert ist, um deren Montage sowie diejenige des Turbosatzes zu erleichtern. Ausserdem ist das Prinzip der Mehrzweckverwendung dergestalt realisiert, dass die Haltegerüste des Dampferzeugers oder der Kohlbunker gleichzeitig für die Aufnahme von Nebenanlagen ausgerüstet sind und der Portalkran sowohl Dampferzeuger- wie auch Stromerzeugerteile bedienen kann. Das nach diesem Konzept erstellte Dampfkraftwerk ist sehr kompakt und auf einem engen Grundriss zusammengefasst. Der Schwerpunkt dieser Lösung liegt in der Verminderung des Bauaufwands. Die Vorteile eines geringen Flächenbedarfs und der Mehrzweckverwendung von Haltegerüsten werden durch eine vertikale Anordnung zahlreicher Anlagenteile erkauft. Gerade diese vertikale Anordnung zahlreicher Anlagenteile, deren Montage mit Hilfe des hoch aufgestellten Portalkrans während der Bauphase erleichtert wird, schliesst in der Betriebsphase einen Einsatz des Krans für notwendige Reparatur- und Wartungszwecke derselben Anlagenteile aus. Dessen Einsatzbereich bleibt nach der Bauphase im wesentlichen auf die Turbogruppe und einige wenige in den oberen Arbeitsebenen angeordnete Anlagentelle beschränkt, wohingegen die Anlagenteile der unteren und sämtlicher Zwischenebenen seinem Zugriff weitgehend entzogen sind.It is known per se through the installation of power plants in an open-air construction to shorten the construction time. However, this design in turn requires a number of disadvantages with regard to their operation as well as their maintenance and repair. In this context, DE 1426918 A1 and BE 669251 disclose the concept a steam power plant that is shorter in construction time and with reduced investment costs created and thereby reduce the disadvantages. This Concept is essentially based on the fact that the turbo set is in an alley between the steam generator is arranged and a gantry crane on the steam generator is mounted to facilitate their assembly and that of the turbo set. In addition, the principle of multi-purpose use is implemented in such a way that the holding frames of the steam generator or the coal bunker at the same time are equipped for the reception of ancillary systems and the gantry crane both Steam generator and power generator parts can operate. That after this Conceptual steam power plant is very compact and on a narrow floor plan summarized. The focus of this solution is reduction of the construction effort. The advantages of a small footprint and multi-purpose use of scaffolding are arranged vertically bought numerous parts of the plant. This vertical arrangement is particularly numerous System parts, the assembly of which with the help of the high erected gantry crane the construction phase is facilitated, use of the Crane for necessary repair and maintenance purposes of the same system parts out. Its area of application remains essentially after the construction phase Turbogruppe and a few plant locations arranged in the upper working levels limited, whereas the plant parts of the lower and all Intermediate levels are largely removed from its access.

Darstellung der ErfindungPresentation of the invention

Hier will die Erfindung Abhilfe schaffen. Ausgehend von dem genannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Dampfkraftwerk zu schaffen, das sich durch eine sehr hohe Wartungs- und Reparaturfreundlichkeit auszeichnet. Darüber hinaus soll ein Dampfkraftwerk geschaffen werden, das eine weitgehende Standardisierung erreicht und an einer Vielzahl von möglichen Standorten erstellt werden kann.
Die Erfindung geht somit aus von einem Dampfkraftwerk in Freilauftaufstellung, im wesentlichen bestehend aus einem Dampferzeuger, einer Turbogruppe mit Kondensationsdampfturbine und Generator, einem wassergekühlten Kondensator, einer anzapfdampfbeheizten Vorwärmeranlage und einem Portalkran und zeichnet sich dadurch aus, daß sämtliche Komponenten des Dampfkraftwerkes, inklusive des Brennstofflagerplatzes, bodennah und wenigstens annähernd niveaugleich angeordnet sind und der Portalkran eine Fläche überstreicht, in der die Turbogruppe mitsamt dem Kondensator, der Vorwärmeranlage mit zugehörigen Pumpen sowie die Transformatoren angeordnet sind.The invention seeks to remedy this. Based on the prior art mentioned, the invention has for its object to provide a steam power plant, which is characterized by a very high maintenance and repair friendliness. In addition, a steam power plant is to be created that achieves extensive standardization and can be built at a large number of possible locations.
The invention is thus based on a free-standing steam power plant, essentially consisting of a steam generator, a turbo group with a condensation steam turbine and generator, a water-cooled condenser, a preheater system heated by tap steam and a gantry crane, and is characterized in that all components of the steam power plant, including the fuel storage area , are arranged close to the ground and at least approximately at the same level and the gantry crane covers an area in which the turbo group together with the condenser, the preheater system with associated pumps and the transformers are arranged.

Wenn der Dampferzeuger, die Rauchgasreinigung und der Kamin in Reihe in einer gemeinsamen Rauchgasachse verlegt werden, so wird zweckmäßigerweise die Turbogruppe in unmittelbarer Nähe daneben angeordnet und parallel dazu ausgerichtet.When the steam generator, the flue gas cleaning and the chimney in one row common flue gas axis are laid, it is expedient the turbo group is arranged in close proximity and parallel to it aligned.

Wenn der Brennstofflagerplatz eine Kohlehalde ist, ist es angebracht, ihn - in der Hauptwindrichtung gesehen - windabwärts hinter der Turbogruppe und dem Dampferzeuger anzuordnen.If the fuel storage area is a coal dump, it is appropriate to use it - in the Main wind direction seen - downstream of the turbo group and the Arrange steam generator.

Der Vorteil all dieser Maßnahmen ist insbesondere darin zu sehen, daß die Standardisierung des Anlagen-Engineerings und der Komponenten die Investitionskosten in bemerkenswertem Umfang reduziert. Den Grundriß des Kraftwerkes bildet ein eindeutig definiertes Rechteck. Dies ermöglicht es, die Anlage zu jedem beliebigen Zeitpunkt durch bloßes Aneinanderreihen von solchen Rechtecken zu erweitern. Dabei kann auf das bei Anlagenerweiterungen bisher übliche sehr umfangreiche Projektengineering verzichtet werden. Die nebeneinander anzuordnenden Kraftwerksblöcke sind identisch; lediglich die Erschliessungsstraßen sind minimal anzupassen. Ein weiterer Vorteil ist in der konsequent umgesetzten Freiluftaufstellung zu sehen. Hierdurch kann auf die kosten- und zeitaufwendige Erstellung von Gebäuden wie z.B. Kessel- und Maschinenhaus verzichtet werden. Die Maßnahme, daß die Turbogruppe mitsamt dem Kondensator, der Vorwärmeranlage mit zugehörigen Pumpen sowie zumindest der Eigenbedarftransformatoren so arrangiert sind, daß sie von einem Portalkran überstreichbar sind, definiert auch für diese Komponenten einen rechteckigen Querschnitt. Hierdurch können die Anlagenteile auf engstem Raum unmittelbar nebeneinander angeordnet werden ohne den Betrieb und Wartung zu beeinträchtigen. Für Wartungs- und Reparaturarbeiten kann auf den Kran zurückgegriffen werden. Diese Anordnung ermöglichst zudem kürzestmögliche Verbindungen zwischen den diversen Anlagenteilen, was sich wiederum vorteilhaft auf Montage und Instandhaltung auswirkt. The advantage of all these measures is that standardization the plant engineering and the components the investment costs reduced to a remarkable extent. The layout of the power plant forms a clearly defined rectangle. This allows the attachment to everyone at any time simply by stringing together such rectangles expand. In doing so, we can rely on what was previously very extensive for system expansions Project engineering can be dispensed with. The to be arranged side by side Power plant blocks are identical; only the access roads are minimal adapt. Another advantage is the consistently implemented outdoor installation to see. This allows for the costly and time-consuming creation of buildings such as Boiler and machine house can be dispensed with. The Measure that the turbo group together with the condenser, the preheater with associated pumps and at least the own-use transformers are arranged so that they can be painted over by a gantry crane also a rectangular cross section for these components. This can the system parts are arranged directly next to each other in a very small space without affecting operation and maintenance. For maintenance and repair work can be used on the crane. This arrangement enables also the shortest possible connections between the various parts of the system, which in turn has an advantageous effect on assembly and maintenance.

Die sinnvolle Maßnahme, die Kohlehalde windabwärts hinter der Turbogruppe und dem Dampferzeuger anzuordnen, beeinträchtigt das Erfordernis nach einem rechteckigen Querschnitt der Anlage keineswegs und ist unabhängig von der Windrichtung durchführbar. Kohlestaubemissionen im Bereich der technischen Anlagen und der Verwaltungsbetriebe können auf diese Weise vermieden werden. Der angestrebte rechteckige Querschnitt ist auch in jedem Falle realisierbar in Bezug auf die örtliche Lage des zu Kühlzwecken erforderlichen Gewässers. Der jeweilige Situationsplan berücksichtigt selbstverständlich diese Wasserlage, wobei auch hier auf kürzeste Verbindungswege Wert gelegt wird.The sensible measure, the coal dump behind the turbo group and Arranging the steam generator affects the need for one rectangular cross section of the system in no way and is independent of the Wind direction feasible. Coal dust emissions in the area of technical Systems and administrative operations can be avoided in this way. The desired rectangular cross section can also be achieved in any case in relation to the location of the water required for cooling purposes. The The respective situation plan naturally takes this water position into account Here too, the shortest connection paths are important.

Ein ebenerdig aufgestellter Flachbett-Aufnehmer ist zur Aufgabe der ungemahlenen Kohle auf das Schrägband zum Kohlebrecher vorgesehen. Dadurch kann auf die bisher übliche großräumige und tiefe, ausbetonierte, unterirdische Aufnehmer-Grube verzichtet werden, was die Tiefbauarbeiten erheblich reduziert.A flat-bed transducer set up at ground level is the task of the unground one Coal provided on the bias belt to the coal crusher. This can help the previously common large-scale, deep, concrete, underground sensor pit be dispensed with, which considerably reduces civil engineering work.

Der Dampferzeuger wird vorzugsweise mit grob gemahlener Kohle aus Kohlesilos versorgt. Dabei ist es sinnvoll, wenn die dem Dampferzeuger zugeordneten Kohlesilos mit dem vorgelagerten Kohlebrecher über eine zumindest annähernd horizontal verlaufende Fördereinrichtung mit anschliesssender vertikaler Fördereinrichtung verbunden sind. Durch die ebenerdige Aufstellung der horizontal verlaufenden Fördereinrichtung können aufwendige Stahlgerüste vermieden werden.The steam generator is preferably made from coal silos with coarsely ground coal provided. It makes sense if the coal silos assigned to the steam generator with the upstream coal crusher over an at least approximately horizontal running conveyor with connecting transmitter vertical conveyor are connected. Due to the level installation of the horizontal Conveyor equipment can avoid expensive steel structures.

Die Dampfturbine weist einen axialen Austritt auf, wodurch sich der Dampfkondensator in der axialen Verlängerung der Dampfturbine befindet. Diese Lösung, die sich aufgrund der bodennahen Aufstellung der Turbogruppe anbietet sowie die Tatsache der Freiluftaufstellung, ermöglichen den uneingeschränkten Zugang zum Kondensator. Wenn Kondensatorrohre ausgetauscht werden müssen, ist es nicht mehr wie bisher erforderlich, Fassadenelemente eines Gebäudes zu entfernen. Außerdem kann für derartige Wartungsarbeiten der den Kondensator überstreichende Portalkran verwendet werden.The steam turbine has an axial outlet, which causes the steam condenser located in the axial extension of the steam turbine. This solution, due to the installation of the turbo group close to the ground offers as well as the fact of the outdoor installation, enable the unrestricted access to the capacitor. When replacing condenser tubes facade elements are no longer required as before to remove a building. It can also be used for such maintenance work the portal crane sweeping over the capacitor can be used.

Es ist vorteilhaft, wenn alle Vorwärmer wasserseitig für den gleichen Druck ausgelegt sind, im wesentlichen die gleiche Dimensionen aufweisen und neben der Turbogruppe liegend angeordnet sind. Diese Maßnahme garantiert kürzeste wasser- und dampfseitige Verbindungen und erlaubt bei Wartungsarbeiten ebenfalls die Benutzung des Portalkrans.
Ausgehend von der Erkenntnis, daß die Bauzeit eines Kraftwerkes aufgrund der fehlenden Vorabplanung und der Anpassung an Kundenspezifikationen heute auβerordentlich lang ist, fördert die Erfindung eine weitgehende Standardisierung eines Kraftwerks, welches an einer Vielzahl von möglichen Standorten erstellt werden kann.It is advantageous if all preheaters on the water side are designed for the same pressure, have essentially the same dimensions and are arranged next to the turbo group. This measure guarantees the shortest water and steam connections and also allows the use of the gantry crane for maintenance work.
Based on the knowledge that the construction time of a power plant is extremely long due to the lack of advance planning and adaptation to customer specifications, the invention promotes extensive standardization of a power plant, which can be built at a variety of possible locations.

    • Weg zur Ausführung der ErfindungWay of carrying out the invention

    Gemäß Fig. 1 ist ein Anlagenmodul, welches sämtliche Kraftwerkskomponenten enthält, mit 200 bezeichnet. Ein solches Modul könnte beispielsweise eine 150 MW-Anlage umfassen und wird mit Vorteil in einer rein industriellen Zone erstellt, um Anwohner vor Emissionen wie Staub, Lärm und Lastwagenverkehr zu schützen. Mit 6 ist der Brennstofflagerplatz bezeichnet. Im vorliegenden Fall handelt es sich um ein offenes Kohlelager mit rechteckigem Grundriß. Im gezeigten Beispiel grenzt die Kohlehalde unmittelbar an einem Fluß 20 an, was bedeutet, daß die Kohleanlieferung mittels Schiff erfolgen könnte. Selbstverständlich kann dies auch über die Eisenbahn oder mittels Lastwagen über Erschließungstraßen 36 erfolgen. Möglich wäre auch der Transport über Förderbänder, falls sich die Anlage in der Nähe einer Kohlemine befindet.1 is a plant module, which contains all power plant components contains, designated 200. Such a module could, for example, be a 150th MW plant and is advantageously created in a purely industrial zone, to protect residents from emissions such as dust, noise and truck traffic. The fuel storage location is designated by 6. In the present case it is an open coal store with a rectangular plan. In the example shown adjoins the coal dump directly on a river 20, which means that the Coal could be delivered by ship. Of course this can also by rail or by truck via access roads 36. Transport via conveyor belts would also be possible if the system is in located near a coal mine.

    Ausgehend von dieser Kohlehalde 6 bestimmen nunmehr die Hauptwindrichtungen 9 die grundsätzliche Ausrichtung der Kraftwerkselemente.Starting from this coal stockpile 6, the main wind directions now determine 9 the basic alignment of the power plant elements.

    Die Kohle wird von der Halde 6 zunächst mittels Schaufellader 49 - welcher während der Erstellungsphase auch zu Aushubarbeiten benutzt werden kann - auf einen Flachbett-Aufnehmer 10 geschüttet (Fig. 4). Von dort aus gelangt das angehäufte Fördergut 41 auf das zum Kohlebrecher 20 führende Schrägband 11. Wie bereits eingangs erwähnt, kann durch den Aufnehmer 10 auf eine ausbetonierte Grube, in welche die Kohle über Trichter auf ein Förderband geleitet wird, verzichtet werden. Da sich der Aufnehmer 10 ebenerdig auf einer Fundamentplatte befindet, reduziert sich gegenüber der Grubenlösung durch die neue Maßnahme auch die Länge des Schrägbandes 11, welches auf den üblicherweise etwa 15 - 20 m hohen Einlass des Brechergebäudes 12 fördern muss.The coal is first removed from the heap 6 by means of a shovel loader 49 - which during the creation phase can also be used for excavation work - on one Flatbed transducer 10 poured (Fig. 4). From there comes the accumulated Conveyed goods 41 on the bias belt 11 leading to the coal crusher 20 already mentioned at the beginning, can be concreted by the transducer 10 Pit in which the coal is fed via a hopper to a conveyor belt is dispensed with become. Since the transducer 10 is at ground level on a foundation plate is reduced compared to the pit solution by the new measure also the length of the bias tape 11, which on the usually about 15 - 20 m high inlet of the crusher building 12 must promote.

    Vom Kohlebrecher aus gelangt das Fördergut zunächst über eine horizontale Fördereinrichtung 14 und dann über eine vertikale Fördereinrichtung 15 auf einen Horizontal-Förderer 43, von dem aus in die Kohlesilos 13 gefüllt wird. Gegenüber der bisher üblichen Schrägbandförderung zu den Silos hat diese Lösung einige Vorteile. Da sich die Beschickung von konventionellen Kesselsilos in der Regel auf einer Höhe von 50 m befindet, bedarf es bei der Schrägbandförderung mit üblicher 14° - 15° Neigung einer Länge von nahezu 200 m. Mit der vorliegenden neuen Maßnahme kann diese Länge drastisch reduziert werden, so daß der Kohlebrecher 20 in nächster Kesselnähe angeordnet werden kann. Darüber hinaus kann die horizontale Fördereinrichtung 14 ebenerdig auf einfachen Betonschwellen errichtet werden. Auf umfangreiche Stahlkonstruktionen wie bei Schrägbandförderung, die überdies bei der Montage eine große Krankapazität verlangen, kann verzichtet werden. Es versteht sich, daß auch der Zugang zu einem in Bodenhöhe verlaufenden horizontalen Förderbandes wegen des Wegfalls von Bedienungs- und Laufgängen erleichtert wird.From the coal crusher, the material to be conveyed initially arrives via a horizontal conveyor 14 and then via a vertical conveyor 15 to a horizontal conveyor 43, from which the coal silos 13 are filled. Across from This solution has some of the previously used bias belt conveying to the silos Benefits. Since the loading of conventional boiler silos usually is at a height of 50 m, it is necessary for the inclined belt conveyor with usual 14 ° - 15 ° inclination of a length of almost 200 m. With the present new measure, this length can be reduced drastically, so that the coal breaker 20 can be arranged in the immediate vicinity of the boiler. Furthermore can the horizontal conveyor 14 at ground level on simple concrete sleepers be erected. On extensive steel structures such as in the case of bias belt conveying, which also require a large crane capacity during assembly, can be dispensed with. It goes without saying that access to one is at ground level horizontal conveyor belt due to the elimination of operating and walkways is made easier.

    Diese Bauart - zunächst horizontal, dann vertikal - erlaubt überdies die grundsätzliche Standardisierung der anschließenden vertikalen Fördereinrichtung 15. Hierbei handelt es sich um ein ummanteltes Becherwerk mit einer einfachen Tragstruktur, welches ebenfalls ebenerdig aufgestellt ist und zur Aufnahme von horizontalen Lasten vorzugsweise mit der Kesselstruktur verbunden ist. Aus alledem ergibt sich, daß nur die Länge der horizontalen Fördereinrichtung 14 jeweils an unterschiedliche Situationen, d.h. Abstand von der Kohlehalde zum Kessel, anzupassen ist.This type of construction - first horizontal, then vertical - also allows the basic Standardization of the subsequent vertical conveyor 15. This is a jacketed bucket elevator with a simple one Support structure, which is also set up at ground level and to accommodate horizontal loads are preferably connected to the boiler structure. From all of that it follows that only the length of the horizontal conveyor 14 each to different situations, i.e. Distance from the coal pile to the boiler, is to be adjusted.

    Der Dampferzeuger 1 arbeitet mit atmosphärischer Wirbelschichtfeuerung. Dabei kann grob gebrochene Kohle mit einer Stückgröße von ca. 6 mm verbrannt werden. Der Vorteil ist darin zu sehen, daß außer dem Kohlebrecher 20 keine zusätzliche Kohlemühle benötigt wird. Der Dampferzeuger wird in einem Stahlrahmen gehalten; auf eine Außenverkleidung und eine Überdachung kann verzichtet werden.The steam generator 1 works with atmospheric fluidized bed combustion. there Coarse broken coal with a size of approx. 6 mm can be burned. The advantage can be seen in the fact that apart from the coal crusher 20 no additional Coal mill is needed. The steam generator is in a steel frame held; an outer cladding and a roof can be dispensed with.

    Wie aus Fig. 1 ersichtlich, ist dem Dampferzeuger ein Tank 24 für flüssigen Brennstoff unmittelbar vorgelagert. Dieser Flüssigbrennstoff wird zum Anfahren des Dampferzeugers und zum Stützfeuer benötigt. Der Standort dieses Tanks ist hinsichtlich kurzer Förderwege gewählt. Der Tank selbst ist in einem betonierten Auffangbecken untergebracht. Die Pumpen 25 für den Anfahrbrennstoff befinden sich unmittelbar neben dem Tank 24 auf Sockeln, die aus einer Betonfundamentplatte herausragen. Dabei ist diese Fundamentplatte als Auffangbecken für den Pumpenbereich ausgebildet.1, the steam generator is a tank 24 for liquid Fuel immediately upstream. This liquid fuel is used to start up of the steam generator and for the support fire. The location of this tank is chosen with regard to short funding routes. The tank itself is in a concrete Collecting basin housed. The pumps 25 for the starting fuel are located right next to the tank 24 on bases made of a concrete foundation slab protrude. This foundation plate is used as a catch basin for the Pump area trained.

    Der Tank kann von der Straße 36 aus mittels Tanklastwagen beladen werden. Als günstige Lösung hat sich herausgestellt, die Pumpen 25 für den Anfahrbrennstoff sowohl zur Speisung der Brenner als auch zum Aufladen des Tankes zu benutzen. Wie dies realisiert werden kann, zeigt Fig. 7. Zum Auffüllen des Tankes saugt die Pumpe 25 über ein entsprechend eingestelltes Dreiwegeorgan 47 Brennstoff aus dem Tankwagen und fördert es über ein weiteres entsprechend eingestelltes Dreiwegeorgan 46 via Fülleitung 48 in das Behältnis. Zum Anfahren des Dampferzeugers und bei Stützfeuer fördert die Pumpe 25 über die wiederum entsprechend eingestellten Dreiwegeorgane 47 und 46 den Brennstoff aus dem Tank 24 zu den Brennern 45 des Kessels 1.The tank can be loaded from road 36 using tank trucks. As A favorable solution has been found, the pumps 25 for the starting fuel to use both to feed the burners and to charge the tank. Fig. 7 shows how this can be achieved. Sucks to fill the tank the pump 25 via a suitably adjusted three-way member 47 fuel out of the tank truck and conveys it via another appropriately set Three-way organ 46 via filling line 48 into the container. For starting up the steam generator and in case of support fire, the pump 25 conveys this in turn accordingly set three-way organs 47 and 46 the fuel from the tank 24 to the Burners 45 of the boiler 1.

    Da der Dampferzeuger 1 mit atmosphärischer Wirbelschichtfeuerung arbeitet, ist eine Entschwefelung der Rauchgase nicht erforderlich. Demzufolge schließt sich an den Kessel unmittelbar die Rauchgasreinigung 16 an, die im wesentlichen aus einem elektrostatischen Abscheider oder einem Gewebefilter besteht. Die gereinigten Abgase werden über den Kamin 17 an die Atmosphäre abgegeben. Aus Fig. 1 ist erkennbar, daß der Dampferzeuger 1, die Rauchgasreinigung 16 und der Kamin 17 in der Längsachse des Kessels in einer sogenannten Rauchgasachse 18 angeordnet sind.Since the steam generator 1 works with atmospheric fluidized bed combustion Desulphurization of the flue gases is not necessary. As a result, it closes to the boiler immediately the flue gas cleaning 16, which consists essentially of an electrostatic precipitator or a fabric filter. The cleaned ones Exhaust gases are released into the atmosphere via the chimney 17. Out Fig. 1 can be seen that the steam generator 1, the flue gas cleaning 16 and Chimney 17 in the longitudinal axis of the boiler in a so-called flue gas axis 18 are arranged.

    Parallel zu dieser Rauchgasachse 18 verläuft nunmehr die Maschinenachse 33. In dieser Achse sind die Turbogruppe 2,3 und der Kondensator 4 sowie die Transformatoren 7 und vorzugsweise die Freiluft-Schaltanlage 34 angeordnet. Man erkennt hier die Abweichung zu üblichen Anlagen, bei denen sich die Turbogruppe in der Regel an der Stirnseite des Dampferzeugers 1 befindet.The machine axis 33 now runs parallel to this flue gas axis 18 this axis are the turbo group 2, 3 and the capacitor 4 and the Transformers 7 and preferably the outdoor switchgear 34 are arranged. You can see the deviation from conventional systems in which the turbo group is usually located on the front side of the steam generator 1.

    Im Modul 200 weiter ersichtlich ist das Straßensystem 36, welches die Anlage erschließt, eine Werkstatt 31 und ein Schaltanlagengebäude 32, sowie die Kühlturmanlage 35, das dahin führende Zusatzwasser 19 und die Wasseraufbereitung 30. Um die Rohrleitungen kurz zu halten, wird eine größtmögliche Nähe der Kühlturmanlage zum Kondensator 4 angestrebt. Für diese Rohrleitungen ist eine überirdische Anordnung gewählt, um die Bauarbeiten anläßlich der Anlagenerstellung nicht zu beeinträchtigen. Die Ausrichtung der aneinandergereihten Kühlzellen geschieht sowohl in Funktion der vorherrschenden Windrichtung als auch der Distanz zur Turbine und zum Kessel; hierbei gilt es, die Ventilation der Kühltürme nicht zu beeinträchtigen.The road system 36, which opens up the system, can also be seen in module 200, a workshop 31 and a switchgear building 32, as well as the cooling tower system 35, the leading make-up water 19 and the water treatment 30. In order to keep the pipes short, the cooling tower system should be as close as possible aimed at capacitor 4. For these pipelines is an unearthly one Arrangement chosen to complete the construction work on the occasion of the plant construction not to interfere. The alignment of the lined-up cold rooms happens both as a function of the prevailing wind direction and the distance to the turbine and the boiler; The cooling towers must be ventilated not to interfere.

    Die Zusatzwasserentnahme geschieht ohne die bisher üblichen umfangreichen Einlaufwerke. Wie in Fig. 6 dargestellt, wird das Zusatzwasser in einfachster Weise über eine Schmutzwasserpumpe 22 gefördert. Diese Pumpe ist im vorliegenden Beispiel in einer im Gewässer 20 versenkten Betonröhre 21 angeordnet. Die Betonröhre besteht vorzugsweise aus einzelnen aufeinandergestapelten Betonringen, von denen mindest einer mit Einlaßöffnungen 44 versehen ist. Die Röhre 21 und die Pumpe 22 stehen auf einer dünnen im Flußboden eingelassenen Betonplatte. Begehbar ist die Wasserentnahme über einen Laufsteg 37. Die Wasserrohre 19 verlaufen in Bodennähe und stützen sich auf Schwellen 38 ab.The make-up water takes place without the usual extensive so far Inlet works. As shown in Fig. 6, the make-up water is very simple promoted via a dirty water pump 22. This pump is in the present Example arranged in a concrete tube 21 sunk in the water 20. The Concrete tube preferably consists of individual stacked concrete rings, at least one of which is provided with inlet openings 44. The tube 21 and the pump 22 stand on a thin concrete slab embedded in the river bottom. The water is accessible via a catwalk 37. The water pipes 19 run close to the ground and are supported on sleepers 38.

    Soweit wie möglich ist mechanisches und elektrisches Zubehör vorgefertigt und vormontiert und wird in Transportcontainern in die Anlage verbracht. Die Container werden bei der Montage mittels Kran auf einfache Betonschwellen gestellt. Damit können sowohl das Anpassungsengineering als auch die Montagezeit reduziert werden. Dies gilt auch für das gesamte Schmier- und Steuerölsystem mitsamt Öltank und Pumpen, welche vormontiert angeliefert und unmittelbar neben der Turbogruppe in einem Beton-Auffangbecken untergebracht werden.As far as possible, mechanical and electrical accessories are prefabricated and pre-assembled and is brought into the system in transport containers. The container are placed on simple concrete sleepers during assembly by crane. In order to both the adaptation engineering and the assembly time can be reduced become. This also applies to the entire lubrication and control oil system together Oil tank and pumps, which are delivered pre-assembled and immediately next to the Turbo group can be accommodated in a concrete catch basin.

    Fig. 2 zeigt bei gleicher Windrichtung und gleichem Flußlauf wie in Fig. 1 eine Dreifachanordnung von Modulen 200. Der einzige Unterschied zur Anlage gemäß Fig. 1 ist in den durchgehenden Straßenzügen 36 zu sehen. Erkennbar ist somit, daß eine Anlage zu einem beliebigen Zeitpunkt ausbaubar ist ohne Beeinträchtigung des Betriebes der bereits bestehenden Module. Ist bereits vor der Erstellung einer Kraftwerksanlage klar, daß sie aus mehreren Modulen bestehen wird, so wird man selbstverständlich Überlegungen hinsichtlich einer gemeinsamen Kohlehalde und einer gemeinsamen Kühlwasserentnahme anstellen.Fig. 2 shows one with the same wind direction and the same river course as in Fig. 1 Triple arrangement of modules 200. The only difference to the system according to Fig. 1 can be seen in the continuous streets 36. It can thus be seen that a system can be expanded at any time without impairment the operation of the existing modules. Is already before creation a power plant clearly that it will consist of several modules, so you will of course considerations regarding a common coal dump and make a joint cooling water withdrawal.

    In Fig. 3 sind jene Elemente gezeigt, die gemäß Erfindung von einem Portalkran 8 überstrichen werden. Am rechten Bildrand ist die Rauchgasachse 18 mit den Elementen Pumpen 25 für Anfahrbrennstoff, Kohlesilos 13, Dampferzeuger 1 und Rauchgasreinigung 16 dargestellt. Die Tatsache, daß die Anlage ohne Gebäude auskommt und die - später zu beschreibende - Anordnung der Vorwärmer auf der dem Kessel abgewandten Seite, führt nunmehr dazu, daß die eigentliche Turbine 2 in unmittelbarer Nähe des Kessels 1 aufgestellt werden kann, was außerordentlich kurze, in dieser Figur nicht dargestellte Verbindungsleitungen ermöglicht. Dies gilt insbesondere für die Frischdampfleitung.3 shows those elements which, according to the invention, are produced by a gantry crane 8 be painted over. On the right edge of the picture is the flue gas axis 18 with the Elements pumps 25 for starting fuel, coal silos 13, steam generator 1 and Flue gas cleaning 16 shown. The fact that the facility has no buildings gets along and the - to be described later - arrangement of the preheaters on the the side facing away from the boiler now leads to the actual turbine 2 can be placed in the immediate vicinity of the boiler 1, which is extraordinary enables short connecting lines, not shown in this figure. This applies in particular to the live steam line.

    Die Kranschienen 39 des Portalkrans 8 sind beidseitig auf Betonsäulen 40 abgestützt, wodurch die Durchführung von Dampfleitungen, Wasserleitungen und Kabelkanälen nicht behindert wird. In ihrer Länge sind sie so bemessen, daß sie den Eigenbedarftransformator 7 und den Speisepumpenblock 26, die beide in der Maschinenachse 33 angeordnet sind, mitumfassen. Die Kranbreite ist so gewählt, daß der Kran (8) auch die Vorwärmeranlage 5 und das in Containerbauweise ausgeführte Schaltanlagengebäude 32 mit bedienen kann. Damit ist zum Ausdruck gebracht, daß dieser Kran (8) auch für die Ersterstellung der Anlage gebraucht wird, wodurch auf mobile Hebeanlagen verzichtet werden kann. Dementsprechend ist die Tragkraft des Kranes für die schwersten Turbinenteile ausgelegt, die anläßlich der Montage zu bewegen sind. Dies gilt nicht für den Generator 3, der vorzugsweise über Gleitschienen in seine Betriebslage gebracht wird.The crane rails 39 of the gantry crane 8 are supported on both sides on concrete columns 40, whereby the implementation of steam pipes, water pipes and cable ducts is not hindered. In length they are dimensioned so that they the In-house transformer 7 and the feed pump block 26, both in the machine axis 33 are arranged, include. The crane width is chosen that the crane (8) also the preheater 5 and the container design executed switchgear building 32 can operate with. This expresses brought that this crane (8) also used for the initial creation of the system , which means that mobile lifting systems can be dispensed with. Accordingly the load capacity of the crane is designed for the heaviest turbine parts, which are to be moved on the occasion of assembly. This does not apply to the generator 3, which is preferably brought into its operating position via slide rails.

    Der Vorteil der bodennahen und wenigstens annähernd niveaugleichen Aufstellung aller genannten Elemente und deren Bedienung mittels Portalkran ist nicht zu unterschätzen. Denn gerade in jenen Marktsegmenten, die unter anderem aus klimatischen Gründen eine Freiluftaufstellung der Anlage ermöglichen, sind oftmals mobile Kräne mit genügender Auslegung und Tragkraft nicht verfügbar. Dies gilt insbesondere bei einem unplanmäßigen Ausfall der Anlage, bei dem sofort Abhilfe geschaffen werden soll.The advantage of being close to the ground and at least almost at the same level Installation of all the elements mentioned and their operation using a portal crane is not to be underestimated. Because especially in those market segments that are under allow the system to be installed outdoors for climatic reasons, are often not mobile cranes with sufficient design and load capacity available. This applies in particular in the event of an unscheduled system failure, which should be remedied immediately.

    Die eigentliche Maschine, hier bestehend aus einer Dampfturbine mit einem Hochdruckteil 2A, einem Mitteldruckteil 2B und einem Niederdruckteil 2C sowie dem Generator 3, ist vorzugsweise so angeordnet dass der Abdampf der Niederdruckturbine 2C axial ausgerichtet ist und daß der Kondensatorhals des auf gleichem Niveau liegenden Kondensators 4 an den Abdampf angeflanscht ist. Diese Bauweise ermöglicht es, daß die Maschinenachse 33 lediglich ca. 5.5 m über Boden zu liegen kommt. Damit erübrigen sich die übliche Betriebsplattform rund um die Maschine sowie allfällige Zwischenböden. Plattformen mit entsprechenden Treppenaufgängen werden nur dort vorgesehen, wo der Zugang für Betriebspersonal und für Wartungszwecke absolut erforderlich ist.The actual machine, here consisting of a steam turbine with a high pressure part 2A, a medium pressure part 2B and a low pressure part 2C and the generator 3 preferably arranged so that the steam the low pressure turbine 2C is axially aligned and that the condenser neck of the condenser 4 lying on the same level is flanged to the exhaust steam. This design allows the machine axis 33 to be only about 5.5 m comes to lie on the floor. This makes the usual operating platform superfluous around the machine and any intermediate floors. Platforms with corresponding Stairways are only provided where there is access for operating personnel and is absolutely necessary for maintenance purposes.

    Dadurch, daß auch die Generatorachse sich au feiner Höhe von ca. 5.5 m über Boden befindet, ist die Möglichkeit gegeben, die nicht dargestellten Generatorschalter und Effegerausrüstung unterhalb des Generators anzuordnen. Sie können auf einer einfachen Betonplatte abgestellt sein. Die Generatorableitungen sind demzufolge an der Unterseite des Generators angeordnet und verlaufen in Reihe, was zu kürzesten Leitungslängen führt. Diese Lösung vermeidet aufwendige Tragkonstruktionen, wie sie vom seitlichen Abgang der Ableitungen oberhalb des Generators her bekannt sind.Because the generator axis is also at a fine height of approx. 5.5 m Ground is the possibility, the generator switch, not shown and to place effector equipment below the generator. You can be placed on a simple concrete slab. The generator leads are therefore arranged on the underside of the generator and run in series, which leads to the shortest cable lengths. This solution avoids complex Supporting structures, such as those from the lateral outlet of the derivatives above of the generator are known.

    Die Turbogruppe 2, 3 mitsamt dem Kondensator 4 ruht auf einer einfachen monolytischen Beton-Fundamentplatte, wobei aus dem Fundament herausragende Säulenplatten die Lager und die Gehäuse abstützen. Die oben erwähnten erforderlichen Plattformen befinden sich auf ca. 4.5 m Höhe über Boden. Auf ihnen sind die Ölleitungen verlegt. The turbo group 2, 3 together with the condenser 4 rests on a simple monolytic one Concrete foundation slab, with protruding from the foundation Pillar plates support the bearings and housings. The above-mentioned required Platforms are approximately 4.5 m above the ground. On them the oil lines are laid.

    Wegen der Freiluftaufstellung sind die Turbinengehäuse mit wetterfesten Umschalungen mit entsprechenden konzipierten Lüftungsöffnungen ausgerüstet. Diese Umschalungen stützen sich ebenfalls auf den genannten Plattformen ab.Because of the open-air installation, the turbine housings have weatherproof casing equipped with appropriate designed ventilation openings. These formworks are also supported on the platforms mentioned.

    Alle Turbinengehäuse sind mit einer horizontalen Trennebene versehen, und zumindest alle Dampfanzapfungen (110 in Fig. 5) sind an der jeweils unteren Gehäusehälfte angeordnet. Für die bei Wartungsarbeiten an den Beschaufelungen oder am Rotor erforderliche Abdeckung der oberen Gehäusehälften müssen diese Leitungen daher nicht entfernt werden. Auch hat die dadurch bedingte tiefe Leitungsverlegung über dem Boden den Vorteil, daß die Abstützungen der Rohre einfach ausgeführt werden können und bereits anläßlich der Erstmontage eine anspruchslose Einrüstung vorgesehen werden kann. Zudem ist der Zugang bei durchzuführenden Schweißarbeiten, Prüfungen und Isolierungen vereinfacht.All turbine housings are provided with a horizontal parting plane, and at least all steam taps (110 in Fig. 5) are on the lower housing half arranged. For the maintenance work on the blades or the cover of the upper housing halves required on the rotor must be covered Lines are therefore not removed. The resulting deep line routing also has above the floor the advantage that the supports of the pipes can be carried out easily and already on the occasion of the initial assembly undemanding scaffolding can be provided. Access is also at welding, testing and insulation to be carried out.

    Die bodennahe Führung der Anzapfdampfleitungen legt es nunmehr nahe, auch die Speisewasservorwärmer 5 entsprechend anzuordnen. Sie werden unmittelbar neben der Turbine liegend angeordnet. Die gewählte Anordnung neben der Turbine 2 bewirkt kurze Anzapfdampfleitungen. Die Tatsache, daß sie nicht auf der Kesselseite, sondern auf der gegenüberliegenden Seite liegen, hat den Vorteil einer Entflechtung der Anzapfdampfleitungen und der zum Dampf-erzeuger führenden Dampfleitungen. Die bodennahe Aufstellung der Vorwärmer ermöglicht zudem einfache Abstützungen in Form von Betonsockeln, welche ebenfalls die Speisewasserleitungen und die Anzapfdampfleitungen tragen.The routing of the steam lines close to the ground now suggests it, too to arrange the feed water preheater 5 accordingly. You will immediately arranged next to the turbine. The chosen arrangement next to the turbine 2 causes short bleed steam lines. The fact that they're not on the boiler side, but lying on the opposite side has the advantage of unbundling the tap steam lines and the one leading to the steam generator Steam lines. The preheater can also be installed close to the floor simple supports in the form of concrete bases, which also serve the feed water pipes and carry the bleed steam lines.

    Alle Vorwärmer 5 weisen im wesentlichen die gleichen Dimensionen auf und sind wasserseitig für den gleichen Druck ausgelegt. Damit ist bereits angedeutet, daß der Wasser-Dampfkreislauf so ausgelegt ist, daß er ohne Speisewassertank/Entgaser auskommt. Dieser an sich übliche große und schwere Apparat ist in der Regel in ca. 15 m Höhe angeordnet und bedarf entsprechend kostspieliger Abstützungen. Der Wegfall dieses Tanks und der entsprechenden Leitungsführung führt zu einer erheblichen Reduzierung der Investitionskosten und der Montagezeit.All preheaters 5 have and are essentially the same dimensions designed for the same pressure on the water side. This already indicates that the water-steam cycle is designed so that it does not have a feed water tank / degasser gets along. This large and heavy apparatus, which is usual per se, is usually Arranged at a height of approx. 15 m and therefore requires expensive supports. The elimination of this tank and the corresponding piping leads to a significant reduction in investment costs and assembly time.

    Der Wasser-Dampfkreislauf ist im Wärmeschaltbild der Fig. 5 vereinfacht dargestellt und nachstehend kurz erläutert. Das Speisewasser tritt mit üblichen Bedingungen (170 bar, ca. 250°C) in den Economiser 101 des Dampferzeugers 1 ein und gelangt von dort in die Dampftrommel 103. Im Naturumlauf wird das Wasser durch den Verdampfer 102 und als Sattdampf zurück in die Trommel geführt. Im mehrteiligen (nicht dargestellt) Überhitzer 104 wird es auf seine Endtemperatur von 540°C erhitzt und über die Frischdampfleitung 105 in den Hochdruckteil 2A der Dampfturbine eingeleitet. Darin entspannt der Dampf unter Abgabe von Leistung auf einen Druck von ca. 40 bar. Über die kalte Zwischenüberhitzerleitung 106 gelangt der Dampf zurück in den Kessel, wird dort im Zwischenüberhitzer erneut auf ca. 540° aufgeheizt und über die heiße Zwischenüberhitzerleitung 108 in den Mitteldruckteil 2B der Dampfturbine eingeleitet. Nach erneuter Teilentspannung gelangt der Dampf vom Mitteldruckteil in den Niederdruckteil 2C, in welchem er auf Kondensatordruck entspannt wird. Im wassergekühlten Kondensator 4 wird der Dampf niedergeschlagen, das Kondensat sammelt sich im nichtdargestellten Hotwell, von wo aus es mittels der Kondensatpumpe 111 in die Vorwärmeranlage gefördert wird. Soweit sind solche Anlagen hinlänglich bekannt.The water-steam cycle is shown in simplified form in the heat circuit diagram of FIG. 5 and briefly explained below. The feed water occurs under normal conditions (170 bar, approx. 250 ° C.) into the economizer 101 of the steam generator 1 and from there it gets into the steam drum 103. In the natural circulation the water becomes through the evaporator 102 and fed back into the drum as saturated steam. in the multi-part (not shown) superheater 104 it will reach its final temperature heated from 540 ° C and via the live steam line 105 into the high pressure part 2A the steam turbine initiated. In it, the steam relaxes while releasing power to a pressure of approx. 40 bar. Via the cold reheater line 106 the steam gets back into the boiler, is there again in the reheater heated to approx. 540 ° and via the hot reheater line 108 in initiated the medium pressure part 2B of the steam turbine. After another partial relaxation The steam passes from the medium pressure part into the low pressure part 2C, in which it is released to condenser pressure. In the water-cooled condenser 4 the steam is deposited, the condensate collects in the not shown Hotwell, from where it goes into the preheater system by means of the condensate pump 111 is promoted. So far, such systems are well known.

    Zur Vereinfachung der Vorwärmeranlage wurde nunmehr folgendes Konzept gewählt. Die Speisepumpe 26 ist zweistufig ausgeführt. Wasserseitig ist eine Vorpumpe 27 stromaufwärts der Vorwärmer 5 und eine Hauptpumpe 28 stromabwärts der Vorwärmer angeordnet. Die zweistufige Speisepumpe ist mit einem gemeinsamen Antrieb 29 versehen. In den Vorwärmern wird das Speisewasser auf die Kesseleintrittstemperatur aufgeheizt mittels Anzapfdampf, welcher über die Anzapfleitungen 110 entsprechenden Stufen der Turbinen 2A-2C entnommen wird. Die zweistufige Ausführung der Speisepumpe hat den Vorteil, daß alle Vorwärmer wasserseitig auf den gleich niedrigen Druck ausgelegt werden können und damit kostengünstig zu fertigen sind. Der Enddruck der Vorpumpe 27 wird gewählt in Funktion des Druckverlustes innerhalb des Vorwärmerstranges und des zulässigen Eintrittsdruckes der Hauptpumpe 29.The following concept has now been chosen to simplify the preheater system. The feed pump 26 is designed in two stages. There is a backing pump on the water side 27 upstream of the preheater 5 and a main pump 28 downstream the preheater arranged. The two-stage feed pump has a common one Provide drive 29. The feed water is heated up in the preheaters the boiler inlet temperature is heated by means of bleed steam, which Tapping lines 110 taken from corresponding stages of turbines 2A-2C becomes. The two-stage version of the feed pump has the advantage that all preheaters water side can be designed for the same low pressure and are therefore inexpensive to manufacture. The final pressure of the backing pump 27 becomes selected as a function of the pressure loss within the preheater line and permissible inlet pressure of the main pump 29.

    Als Besonderheit ist im Vorwärmerstrang zwischen Kondensatpumpe 111 und Speisepumpe 27 ein Ausgleichstank 23 für Kaltkondensat vorgesehen. Dieser Tank kann mit einem dampf- oder inertgasförmigen Druckpolster arbeiten und dient als Vorlage für die Speisepumpe 27. In Funktion tritt dieser Tank insbesondere bei nicht-stationären Betriebszuständen.A special feature is in the preheater line between condensate pump 111 and Feed pump 27, a compensation tank 23 is provided for cold condensate. This Tank can work with a vapor or inert gas pressure cushion and serves as a template for the feed pump 27. This tank particularly functions in non-stationary operating conditions.

    Im Wärmeschaltbild der Fig. 5 ist auch der Generator 3 gezeigt. Dieser Generator 3 ist luftgekühlt, wobei die Kühlerbox 112 direkt an den Generator angeflanscht ist. Eine Besonderheit ist, daß zum Rückkühlen der in geschlossenem Kreis zirkulierenden Kühlluft nichtentsalztes Kühlwasser aus dem Hauptkühlkreislauf 51 entnommen wird. Im Gegensatz zu bisherigen Luft/Wasserkühlern, deren Kühlelemente meist aus Kupfer resp. Nickel ausgeführt sind, wird deshalb Edelstahl verwendet. Nichtsdestoweniger wird das Kühlwassersystem kostengünstiger, da wegen der Verwendung von Hauptkühlwasser zur Generatorkühlung das für sonstige Zwecke benötigte Zwischenkühlsystem, welches mit aufbereitetem Wasser arbeitet, kleiner und somit billiger dimensioniert werden kann.The generator 3 is also shown in the thermal circuit diagram of FIG. 5. This generator 3 is air cooled with the cooler box 112 flanged directly to the generator is. A special feature is that for recooling those circulating in a closed circuit Cooling air is taken from the main cooling circuit 51, not desalinated cooling water becomes. In contrast to previous air / water coolers, their cooling elements mostly made of copper Stainless steel is used. Nevertheless, the cooling water system becomes cheaper because of the use of main cooling water for cooling the generator for others Intermediate cooling system required for the purpose, which works with treated water, can be made smaller and therefore cheaper.

    Aus den Fig. 1 und 3 ist die in nächster Nähe des Generators 4 erfolgte Aufstellung der Transformatoren 7 erkennbar, was zu kurzen Stromschienen 50 führt. Der Eigenbedarftransformator und die Blocktransformatoren sind durch eine Brandschutzwand voneinander getrennt. Die Anlage ist so konzipiert, daß mindestens der Eigenbedarftransformator vom Portalkran aus bedient werden kann.1 and 3 is the set up in the immediate vicinity of the generator 4 of the transformers 7 can be seen, which leads to short busbars 50. The own-use transformer and the block transformers are by a Fire protection wall separated. The system is designed so that at least the own-use transformer can be operated from the gantry crane.

    Die Schaltanlage 34 kann als gasisolierter Hochspannungsmodul konzipiert werden, wodurch einerseits der Landbedarf erheblich reduziert wird und andererseits die Schaltanlage sehr nahe an die Transformatorenanlage errichtet werden kann. Switchgear 34 can be designed as a gas-insulated high-voltage module, which significantly reduces land requirements on the one hand and on the other the switchgear can be installed very close to the transformer system.

    Die Schaltanlagen und der Wartenraum sind ebenfalls als Container ausgeführt. Die Module werden vorgefertigt mittels Portalkran auf eine ebenerdige Fundamentplatte mit umlaufendem Sockel aufgesetzt. Der so entstehende Raum dient als Kabelkeller.The switchgear and the control room are also designed as containers. The modules are prefabricated using a portal crane on a ground-level foundation plate with all-round base. The space thus created serves as a cable basement.

    Die Figuren 8 und 9 zeigen das gewählte Prinzip-Layout einerseits bei anderer Windrichtung, andererseits bei anderem Verlauf des Gewässers. Entsprechend der Vorgabe ist die Kohlehalde 6 bei beiden Anordnungen jeweils windabwärts angeordnet. Anhand dieser Figuren zeigt sich der große Vorteil des Kohleförderkonzepts. Lediglich die Länge und der Verlauf des horizontalen Förderers 14 sind an die neuen Gegebenheiten anzupassen. Die Anlage in Fig. 9 unterscheidet sich von jener in Fig. 8 durch den anders verlaufenden Fluss 20. Dies führt aufgrund der anders zu konzipierenden Wasserentnahme lediglich zu einer unterschiedlichen Geometrie des Moduls 200. Figures 8 and 9 show the selected principle layout on the one hand with another Wind direction, on the other hand with a different course of the water. Corresponding the default is the coal pile 6 in both arrangements downstream arranged. These figures show the great advantage of the coal mining concept. Only the length and the course of the horizontal conveyor 14 are to adapt to the new conditions. The system in Fig. 9 differs from that in Fig. 8 by the differently running river 20. This leads to the differently designed water withdrawal only to a different Geometry of the module 200.
