Description
Das Hauptpatent 383506 hat eine Einrichtung zur Kühlung von Verbrennungsturbinen zum Gegenstand, bei der die Kühlflüssigkeit aus den hohl ausgebildeten Schaufeln in einemThe main patent 383506 has a device for cooling combustion turbines, in which the cooling liquid from the hollow blades in one
. 5 scheibenförmigen Strahl in einen besonderen konzentrischen Ringraum des Gehäuses übertritt. . 5 disc-shaped beam passes into a special concentric annular space of the housing.
Zweck der vorliegenden Erfindung ist, zu verhindern, daß zersprühtes und verdampftes Kühlmittel in den Gasraum übertritt, um die Schaüfelkühlung beherrschen zu 'können und chemische Einflüsse zu verhindern.The purpose of the present invention is to prevent spray and vaporization Coolant passes into the gas space in order to be able to control the schüfel cooling and to prevent chemical influences.
Dies wird gemäß der Erfindung dadurch erreicht, daß das Kühlmittel so abgeleitet wird, daß gegenüber dem Gasraum eine Saugwirkung entsteht, die, soweit es die möglichst eng gehaltenen Spalten zwischen Gehäuse und Laufzeugteilen, wobei besondere Dichtungsringe am Gehäuse Verwendung finden können, zulassen, Gas in den Kühlmittelstrom herüberzieht und mit diesem fortreißt.This is achieved according to the invention in that the coolant is diverted in such a way that that compared to the gas space there is a suction effect, as far as it is kept as close as possible Allow gaps between the housing and running gear parts, whereby special sealing rings can be used on the housing, Gas pulls over into the coolant flow and is carried away with it.
Der Erfindungsgegenstand ist in der Zeichnung in zwei Ausführungsformen schematisch veranschaulicht.The subject matter of the invention is shown schematically in two embodiments in the drawing illustrated.

Zur Erzielung der Saugwirkung ist es zweckmäßig, daß ein Teil des Kühlwassers in tropfbar flüssigem Zustand nach c gelangt. Der andere Teil kann während des Durchganges durch die Schaufeln, unter Ausnutzung der Verdampfungswärme für die Kühlwirkung, verdampfen. Beim Eintritt des Kühlmittels Jn-tien Gehäuseringraum kann durch anfängliche Verengung desselben (Abb. 1) die, -Saugwirkung unterstützt werden.

In order to achieve the suction effect, it is expedient that part of the cooling water reaches c in a dripping liquid state. The other part can evaporate during the passage through the blades, using the heat of evaporation for the cooling effect. When the coolant enters into the housing ring, the suction effect can be supported by initial narrowing of it (Fig. 1). In the further course the annulus is considered (axial section) to the outside, gradually pelted and bent to the side in accordance with the pressure conversion, in order to avoid the impact of coolant particles, thus disturbing the suction effect
