Description

Es ist bekannt, der Energiehunger in der Welt wird steigen. Die Erdöl- und Erdgasvorkommen gehen bald zur Neige. Fossile Brennstoffe wie Erdöl, Kohle und Erdgas werden weiterhin genutzt. Neubauten von Kohle- und Atomkraftwerken werden leider wieder aktuell. Das sind keine guten Aussichten zur Reduzierung von CO2 und zur Bremsung der Erderwärmung.It is known that the hunger for energy in the world will increase. The oil and gas deposits are about to run out soon. Fossil fuels such as oil, coal and natural gas continue to be used. Unfortunately, new builds of coal and nuclear power plants are becoming current again. These are not good prospects for reducing CO2 and stopping global warming.
Viele Kraftwerke haben einen miserablen Wirkungsgrad.
Zitat aus http://de.wikipedia.org/wiki/Wärmekraftwerk:
„Wird die Abwärme nicht zum Heizen verwendet, liegt der Wirkungsgrad eines heutigen Kraftwerkes typischerweise zwischen 30% und 45%.” In China bei 23%. „Viele Wärmekraftwerke nutzen zur Kühlung das Wasser vorbeifließender Flüsse. Das erspart den Kühlturm mit seinen vielen Nachteilen ...”.Many power plants have a miserable efficiency.
Quote from http://de.wikipedia.org/wiki/Härmekraftwerk:
"If the waste heat is not used for heating, the efficiency of today's power plant is typically between 30% and 45%." In China, at 23%. "Many thermal power plants use the water of passing rivers for cooling. This saves the cooling tower with its many disadvantages ... ".
Windkraftanlagen verstärken das Problem der notwendigen Energiespeicherung, und sie müssen bei Überkapazitäten im Stromnetz zeitweise abgeschaltet werden. Es fehlen große Energiespeicher und umweltschonende, billig zu bauende Spitzenlastkraftwerke.Wind turbines increase the problem of the necessary energy storage, and they have to be temporarily switched off in case of excess capacity in the power grid. It lacks large energy storage and environmentally friendly, cheap to build peak load power plants.
Die gesuchte Vorrichtung soll sich vor allem durch eine möglichst effiziente Ausnutzung der zur Verfügung stehenden Energiequellen auszeichnen, auch auf verschiedene Energiequellen variabel zurückgreifen können und die Probleme Energiespeicherung und Stromspitzenlasten lösen helfen. Die genannten Nachteile können damit beseitigt oder zumindest nachhaltig minimiert werden.The sought-after device should be distinguished, above all, by the most efficient utilization of the available energy sources, can also resort to variable sources of energy and help solve the problems of energy storage and peak loads. The disadvantages mentioned can thus be eliminated or at least minimized sustainably.
Es besteht somit die Aufgabe, die Abwärme von Dampfkraftwerken zu nutzen und ihren Wirkungsgrad auf etwa 70% zu erhöhen. Das kann durch eine Vorrichtung zur thermischen Kopplung von Dampfkraftwerken mit Druckluftspeicherkraftwerken erreicht werden. Der Wirkungsgrad von Druckluftspeicherkraftwerken kann dadurch ebenfalls auf etwa 70% gesteigert werden. Bei Druckluftspeicherkraftwerken muss bei Expansion der Luft wieder Wärme zugeführt werden, um eine Vereisung der Turbinen zu vermeiden. Die Wärmezufuhr kann also durch Dampfkraftwerke erfolgen, eine Kombination Druckluftkraftwerke mit Gasturbinenkraftwerken kann damit entfallen.It is therefore the task to use the waste heat of steam power plants and increase their efficiency to about 70%. This can be achieved by a device for the thermal coupling of steam power plants with compressed air storage power plants. The efficiency of compressed air storage power plants can also be increased to about 70%. For compressed air storage power plants, heat must be re-supplied as the air expands to avoid icing of the turbines. The heat can thus be done by steam power plants, a combination of compressed air power plants with gas turbine power plants can be eliminated.
In einer zweckmäßigen Ausführungsform können beispielsweise den Kohlekraftwerken und den Atomkraftwerken Druckluftspeicherkraftwerke zugeordnet werden.In an expedient embodiment, for example, the coal power plants and the nuclear power plants compressed air storage power plants can be assigned.
In einer weiteren zweckmäßigen Ausführungsform kann auch meine Patentanmeldung 10 2009 056 596.5 Wellenkraftwerk, Priorität 31.08.2009, zur Anwendung kommen. Dieses Wellenkraftwerk erzeugt ebenfalls Druckluft und Dampf.In a further expedient embodiment, my
In einer weiteren zweckmäßigen Ausführungsform wird Druckluft in wärmegedämmten Druckluftbehältern und/oder in Kavernen bei etwa 46 bis 72 bar gespeichert.In a further expedient embodiment, compressed air is stored in thermally insulated compressed air tanks and / or in caverns at about 46 to 72 bar.
In einer weiteren zweckmäßigen Ausführungsform wird die Wärme der komprimierten Druckluft in einem Feststoffspeicher zwischengespeichert.In a further expedient embodiment, the heat of the compressed compressed air is temporarily stored in a solids store.
Die erfindungsgemäße Vorrichtung soll nachfolgend anhand eines Ausführungsbeispiels näher erläutert werden. Zur Verdeutlichung dient die beigefügte
Bei dem Dampfkraftwerk
Bei dem Druckluftspeicherkraftwerk
Die Vorrichtung kann wie folgt betrieben werden:
dem Neubau eines Kohlekraftwerkes
the new construction of a coal power plant
Bei dem Druckluftspeicherkraftwerk
Die Vorteile der Vorrichtung sind:
- – die Gesamtwirkungsgrade von Dampfkraftwerken und Druckluftspeicherkraftwerken erhöhen sich enorm auf etwa je 70%
- – Druckluftspeicherkraftwerke nutzen Nachtstrom und sorgen deshalb für einen Ausgleich von Stromspitzenlast zu Stromgrundlast
- – Druckluftspeicherkraftwerke, auch Wellenkraftwerke, die mit Druckluft arbeiten, können Überkapazitäten im Stromnetz zur Speicherung von Druckluft nutzen
- – der Transport von Druckluft in Rohren ist rentabel
- – durch Umlaufkühlung wird stets das gleiche Wasser verwendet, es entstehen keine Reinigungskosten für neues Kühlwasser; Kühltürme entfallen
- – durch die thermische Kopplung sind bedeutend weniger Kraftwerkskapazitäten notwendig
- - The overall efficiency of steam power plants and compressed air storage power plants increases enormously to approximately 70% each
- - Compressed air storage power plants use night-time electricity and therefore compensate for peak current load to basic electricity load
- - Compressed air storage power plants, also wave power plants that work with compressed air, can use excess capacity in the power grid for storing compressed air
- - The transport of compressed air in pipes is profitable
- - By circulation cooling always the same water is used, there are no cleaning costs for new cooling water; Cooling towers omitted
- - Due to the thermal coupling considerably less power plant capacities are necessary
