Abstract

The system provides heat energy directly without intermediate conversion into electrical energy. It is coupled directly to the output shaft of a wind turbine without intermediate gearing and comprises an eddy current brake or a throttled pumping system with oil, or glycerine etc. mixed as the heat transfer medium. The heat may be transferred to a heat store, e.g. a water storage tank, with a heat-insulating packet. Pref. the wind turbine shaft may also be directly coupled to an inductor for providing an auxiliary electrical supply. The system allows a heating system to be powered by the wind with a high output efficiency. It is applicable to plains etc. with low temps. and high winds but no local fuel supply.

Description

Windkraftwerk zur Energiegewinnung Wind power plant for energy generation

Eeschreibung : Ursprünglich wurden Windräder zum Wasserpumpen oder zum Mahlen von Getreide benutzt.Description: Originally, wind turbines were used to pump water or used for grinding grain.

In jüngerer Zeit ist die Entwicklung dahingegangen, daß man zumindest kleinere und mittlere Windkraftwerke gebaut hat, bei denen die anfallende Energie in elektrische Energie umgesetzt wird.More recently the trend has been that at least one has built small and medium-sized wind power plants that use the generated energy is converted into electrical energy.

Da der Anfall der Windenergie unregelmäßig ist, so spielen die Speicherungsprobleme dabei eine besondere Rolle. Bei der Umsetzung in elektrische Energie treten verschiedene Grenzprobleme auf. Beispielsweise kann der elektrische Generator in seiner Größe und Leistung nur für eine mittlere Windgeschwindigkeit ausgelegt werden, sodaß die höheren Windspitzengeschwindigkeiten nicht genutzt werden. Ohne Getriebe kommt man dabei nicht aus, da die Umdrehungszahl der Windrad-Hauptwelle stets niedrig liegt.Since the accumulation of wind energy is irregular, the storage problems play a role a special role in this. When converting into electrical energy, different ones occur Border problems. For example, the electrical generator can vary in size and power can only be designed for an average wind speed, so that the higher wind peak speeds cannot be used. You can get there without a gearbox This does not work because the number of revolutions of the wind turbine main shaft is always low.

Speicherung der Energie ist nicht ohne weiteres möglich. Die Einspeisung der Energie in ein Netz stößt auf erhebliche Schwierigkeiten wegen der Konstanthaltung der Spannung bzw. der Frequenz u.a.m.Storing the energy is not easily possible. The feed The energy in a network encounters considerable difficulties because of the constant maintenance the voltage or the frequency, etc.

Der Hauptgedanke dieser Patentanmeldung erstreckt sich darauf, die. anfallende Windenergie im wesentlichen unmittelbar in Wärme umzusetzen. Dies kann durch Flüssigkeitswirbel-Eremsen oder durch Pumpsysteme mit Drosselkreisen ohne weiteres erfolgen.The main idea of this patent application extends to the. convert wind energy directly into heat. This can through fluid vortex braking or through pump systems with throttle circuits without further take place.

Die Vorteile dieser Art der Energieumsetzung verglichen mit allen anderen bekannten sind beträchtlich, u.zw. aus folgenden Gründen: Die Mittel zur Energieumsetzung sind einfach und ökonomisch.The advantages of this type of energy conversion compared to all of them other known are considerable, u.zw. for the following reasons: The means to Energy conversion is simple and economical.

Speicherungsmöglichkeiten sind ohne weiteres gegeben und beinahe problemlos. Die Energieumsetzung paßt sich in weiten Grenzen dem Anfall der Energie an, sodaß die Windspitzen-Geschwindigkeiten ohne weiteres ausgenutzt werden können. Da der Energieanfall mit b.w.Storage options are readily available and almost problem-free. The energy conversion adapts itself to the accumulation of energy within wide limits, so that the wind peak speeds can easily be exploited. Since the Energy consumption with b.w.

der dritten Potenz der Windgeschwindigkeit steigt, so ist es außerordentlich wichtig, daß man gerade die höheren Windgeschwindigkeiten möglichst voll ausnutzen kann.the cube of the wind speed increases, so it is extraordinary It is important to take full advantage of the higher wind speeds can.

Man kann zur Energieumsetzung in Wärme insbesondere auch Flüssigkeiten benutzen, die höhere Temperaturen vertragen (höhere Siedepunkte haben), die obendrein eine höhere Viskosität haben und die zusätzlich noch eine gute Schmierwirkung auf die Pumpsysteme ausüben.Liquids in particular can also be used to convert energy into heat use, which can tolerate higher temperatures (have higher boiling points), the on top of that have a higher viscosity and also have a good lubricating effect exercise the pumping systems.

Der Wirkungsgrad bei dieser Energieumsetzung ist fast 100 %.The efficiency of this energy conversion is almost 100%.

Auch die Wärme, die als Verlustwärme im Pumpsystem entsteht, wird ja als Wärme voll mit genutzt. Es muß selbstverständlich sowohl das Pumpsystem als das Drosselsystem als die Zuleitungen der erwärmten Flüssigkeit zu den Speicherbehältern oder anderen Nutzern entsprechend wärmeisoliert sein, was heutzutage kein besonderes Problem darstellt.The heat that is generated as heat loss in the pump system is also used yes fully used as heat. It must of course both the pumping system as the throttle system as the supply lines for the heated liquid to the storage tanks or other users should be appropriately thermally insulated, which is nothing special nowadays Problem.

ßei Benutzung von Flüssigkeiten mit höheren Siedepunkten kann natürlich auch ohne weiteres die Wärme benutzt werden, um Wasser zu verdampfen und zu destillieren. Als Flüssigkeit zur Wärmeerzeugung und Übertragung kommen Öle infrage, u.a. auch Silikonöl.When using liquids with higher boiling points, of course the heat can easily be used to evaporate and distill water. Oils can be used as the liquid for heat generation and transmission, including among others Silicone oil.

Letzteres dürfte dadurch besondere Vorteile bieten, daß es in fast beliebigen Zähigkeiten hergestellt werden kann, daß es einen relativ niedrigen Temperaturkoeffizienten der Viskosität aufweist und daß es eine verhältnismäßig hohe Hitzebeständigkeit hat.The latter is likely to offer particular advantages in that it is in almost any toughness can be produced in that it has a relatively low temperature coefficient the viscosity and that it has a relatively high heat resistance Has.

An vielen Stellen der Erdoberfläche dürfte die Erzeugung von Wärmeenergie wichtiger sein als alles andere. Wenn man an Gegenden wie Patagonien denkt im Süden von Argentinien, so ist das Hennzeichnende dort, daß Wind außerordentlich häufig und stark ist, daß andere Energiequellen nicht existieren, nicht einmal Orennmaterialien und daß auch die Energiezufuhr fast unmöglich ist.In many places on the earth's surface, the generation of thermal energy is likely be more important than anything else. When you think of places like Patagonia in the south from Argentina, the characteristic of Henn is there, that wind is extraordinarily frequent and what is strong is that other sources of energy do not exist, not even orenn materials and that the supply of energy is almost impossible.

Zudem kommt Wasser häufig nur als Salzwasser vor, so daß man es destillieren muß. Alles dies spricht dafür, daß ein mittleres Windkraftwerk dort sozusagen die Existenzbasis für Menschen bilden kann. Aber auch in unseren Hüstengebieten und in ähnlichen Gebieten b.w.In addition, water often occurs only as salt water, so that it is distilled got to. All of this suggests that a medium-sized wind power station there, so to speak Can form the basis of existence for people. But also in our hip areas and in similar areas, etc.

wäre die Versorgung von einzelnen Häusern oder Gehöften mit Hilfe der Windenergie bei direkter Umsetzung der Energie in Wärme eine ausgezeichnete Sache.would be the supply of individual houses or homesteads with help wind energy with direct conversion of the energy into heat an excellent Thing.

Zum Schluß soll noch bemerkt werden, daß es selbstverständlich möglich ist, neben der Umsetzung der Energie in Wärme, eInen kleineren Teil des anfallenden Energieteils auch in elektrische Energie umzusetzen, so daß eine Hausversorgung mit Strom möglich ist.Finally it should be noted that it is of course possible is, besides the conversion of the energy into heat, a smaller part of the accruing Energy part also convert into electrical energy, so that a house supply is possible with electricity.

Dabei könntei. man Induktoren benutzen, die unmittelbar auf der Windrad-Hauptwelle sitzen und die ohne Getriebe arbeiten.This could be. you can use inductors directly on the main shaft of the wind turbine sit and work without a gearbox.

Sei begrenztem Energiebedarf macht dies keine besondere Schwierigkeiten.With a limited energy requirement, this does not pose any particular difficulties.
