Abstract
Description
Definitiondefinition
Als Turbine wird hier ein System bezeichnet, in denen Dampf unter einem Druck einströmt, in einem feststehenden Düsensystem (Leitbeschaufelung) entspannt und hierbei beschleunigt wird. Nach dem Düsensystem wird der Dampf über einem rotierenden Schaufelsystem (Laufbeschaufelung) umgelenkt, eventuell weiter entspannt und gibt dabei seine Strömungsenergie über die Schaufeln an eine verbundene Welle ab. Von der Welle wird die Rotationsenergie danach zur weiteren Nutzung übertragen. U. a. können durch die Welle Generatoren zur Stromerzeugung angetrieben werden.As a turbine is here called a system in which steam flows under pressure, in a fixed nozzle system (Leitbeschaufelung) relaxed and thereby accelerated. After the nozzle system, the steam over a rotating blade system (blading) deflected, possibly further relaxed, while its flow energy through the blades to a connected shaft from. The rotational energy is then transmitted by the shaft for further use. U. a. can be powered by the shaft generators for power generation.
Radialturbinen sind gegenüber Axialturbinen dadurch gekennzeichnet, dass der Dampf sich durch das Düsensystem zur Rotationsachse des Laufrades hin bewegt und nach Nutzung der Strömungsenergie parallel zu dieser Rotationsachse abströmt.Radial turbines are compared to axial turbines characterized in that the steam moves through the nozzle system to the axis of rotation of the impeller out and flows after use of the flow of energy parallel to this axis of rotation.
Eine ORC-Anlage ist durch das Vorhandensein von Verdampfern, Kondensatoren, Turbinen und Pumpen gekennzeichnet, in denen ein anderes Medium als Wasser zum Zwecke der Umwandlung von thermischer in elektrischer Energie die Zustände von flüssig zu gasförmig und umgedreht wechselt.An ORC system is characterized by the presence of evaporators, condensers, turbines and pumps in which a medium other than water, for the purpose of converting thermal energy into electrical energy, changes states from liquid to gaseous and vice versa.
Anwendungapplication
Radialturbinen finden oft in ORC-Anlagen mit geringer Leistung zum Antrieb eines elektrischen Generators Anwendung. Mittels dieser ORC-Anlagen wird z. B. aus der Abwärme von Verbrennungsmotoren noch zusätzlich elektrische Energie gewonnen.Radial turbines are often used in ORC systems with low power to drive an electric generator application. By means of these ORC systems z. B. from the waste heat of internal combustion engines additionally obtained electrical energy.
Sowohl Düsenkränze als auch Schaufelräder von Radialturbinen können oft preisgünstig als prismatische Körper meist aus jeweils einem Stück gefertigt werden.Both nozzle rings and paddle wheels of radial turbines can often be inexpensively manufactured as a prismatic body usually from one piece.
Die Erfindung bewirkt mit einfachen Mitteln durch ein preiswertes zusätzliches Teil eine Effizienzerhöhung solcher Turbinen und damit der gesamten ORC-Anlagen.The invention causes by simple means by an inexpensive additional part an increase in efficiency of such turbines and thus the entire ORC systems.
