Abstract[English]
The Internally Condensing Steam Turbine (ICST) is a device operating on the basis of vortex tubes, i.e., devices that utilize the swirling motion of the compressed working medium to separate it into cold and hot streams. The turbine's vortex tube body (1.5), due to the friction forces of the working medium against the inner walls of the tube body, rotates, from where mechanical energy is extracted from the turbine. The interior of the tube body (1.5) expands towards the outlet (1.7) of the hot working medium stream. The inner walls of the tube body (1.5) contain channels (2.12) with an outlet (2.15) separated from the outlet (1.7), through which the working medium condensate is automatically removed outside the turbine. Inside the turbine, the working medium condenses automatically, and the condensation energy is transferred to the working medium vortex, which increases the overall efficiency of the turbine.[French]
La turbine à vapeur à condensation interne (ICST) est un dispositif fonctionnant sur la base de tubes à tourbillon, c'est-à-dire des dispositifs qui utilisent le mouvement tourbillonnant du milieu de travail comprimé pour le séparer en flux froid et chaud. Le corps de tube à tourbillon de turbine (1.5), en raison des forces de frottement du milieu de travail contre les parois intérieures du corps de tube, tourne, à partir de l'endroit où de l'énergie mécanique est extraite de la turbine. L'intérieur du corps de tube (1.5) se dilate vers la sortie (1.7) du flux de milieu de travail chaud. Les parois intérieures du corps de tube (1.5) contiennent des canaux (2.12) avec une sortie (2.15) séparée de la sortie (1.7), par laquelle le condensat de milieu de travail est évacué automatiquement à l'extérieur de la turbine. À l'intérieur de la turbine, le milieu de travail se condense automatiquement, et l'énergie de condensation est transférée au tourbillon de milieu de travail, ce qui augmente le rendement global de la turbine.
