Abstract
Reibungsturbinenantrieb, wobei zwischen mindestens zwei rotierenden Antriebsscheiben mit zentraler Öffnung eine Dampfströmung vom Innenradius zum Außenradius geleitet wird, wobei die Dampfströmung durch mindestens eine Düse am Innenradius zwischen die Antriebsscheiben geleitet wird, dadurch gekennzeichnet daß die mindestens eine Düse mit den Antriebsscheiben rotiert, daß ein Leitrad zwischen der mindestens einen Düse und den Antriebscheiben die Dampfströmung umlenkt und daß mittels eines rotierenden Wärmetauschers die Antriebsscheiben und das Arbeitsfluid gekühlt werden.Reibungsturbinenantrieb, wherein between at least two rotating drive pulleys with a central opening a steam flow is passed from the inner radius to the outer radius, wherein the steam flow is passed through at least one nozzle at the inner radius between the drive pulleys, characterized in that the at least one nozzle rotates with the drive pulleys that a stator between the at least one nozzle and the drive disks deflects the steam flow and that by means of a rotating heat exchanger, the drive disks and the working fluid are cooled.
Description

Im
Grundsätzlich scheint dieser Turbinentyp seine Stärken bei kleinen Volumenströme zu haben, wie es in den Studien zu Teslaturbinen und Pumpen in einer Arbeit von Warren Rice (Proc. IV International Nikola Tesla Symposium – Sept. 23–25. 1991) zusammengefasst ist.Basically, this type of turbine appears to have its strengths in small volume flows, as summarized in the studies on Teslaturbines and Pumps in a paper by Warren Rice (Proc IV International Nikola Tesla Symposium - Sept. 23-25, 1991).
Im Patent
Der Nachteil beim Einsatz von konventioneller Dampfturbinentechnologie im kleinen Leistungsbereich ist der geringe Wirkungsgrad bei der Umsetzung von Wärme in Kraft (Fritz Dietzel, Dampfturbinen, 3. Ausgabe, München 1980). Um eine gute Ausnutzung der Energie des Arbeitsfluides zu erreichen, wären mehrere Turbinenstufen notwendig. Mit jeder Turbinenstufe erhöhen sich jedoch die Verluste, was wiederum die Anzahl der Stufen im niedrigen Leistungsbereich limitiert.The disadvantage of using conventional steam turbine technology in the small power range is the low efficiency in the conversion of heat into power (Fritz Dietzel, steam turbines, 3rd edition, Munich 1980). To achieve a good utilization of the energy of the working fluid, several turbine stages would be necessary. With each turbine stage, however, the losses increase, which in turn limits the number of stages in the low power range.

Aufgabenstellungtask
Prinzipiell gibt es viele potenzielle Einsatzgebiete für kleine, preiswerte Turbinen. Beispiele sind der Einsatz zur Stromerzeugung in Gebieten, die nicht an das Stromnetz angeschlossen sind, sowie in Blockheizkraftwerken für Einfamilienhäuser.In principle, there are many potential applications for small, inexpensive turbines. Examples are the use of power generation in areas that are not connected to the power grid, as well as in combined heat and power plants for single-family homes.
Entscheidend ist der einfache und damit kostengünstige Aufbau, der einen wirtschaftlichen Einsatz von dezentraler Kraft-Wärmekopplung erst möglich macht. Die Konstruktion soll somit durch Einfachheit und Langlebigkeit ausgezeichnet sein.The decisive factor is the simple and thus cost-effective design, which makes economical use of decentralized cogeneration possible. The construction should therefore be characterized by simplicity and longevity.
Durch den vorgeschlagenen Aufbau einer einfachen Kohäsionsturbine mit Einschuss am Innenradius, sowie gekühlten Scheiben wird eine effiziente Umsetzung von Wärme in mechanische Energie erreicht. Die mechanische Energie kann wiederum in Elektrizität umgewandelt, während die auf die Scheiben übertragene Wärme für Heizzwecke genutzt werden kann.The proposed construction of a simple cohesive turbine with internal radius injection and cooled disks achieves efficient conversion of heat to mechanical energy. The mechanical energy can in turn be converted into electricity, while the heat transferred to the discs can be used for heating purposes.
