Abstract

L'invention concerne un système de turbines (110) comportant (A) une première turbine (151), (B) une deuxième turbine (152), (C) une troisième turbine (153), (D) une transmission centrale (130) qui, du côté entrée, est couplée mécaniquement aux trois turbines et, du côté sortie, comporte un raccord mécanique pour le raccordement à une machine de travail (120), (E) une première conduite de fluide (161) pour acheminer un fluide de travail depuis la première turbine (151) vers la deuxième turbine (152), (F) une deuxième conduite de fluide (162) pour acheminer le fluide de travail depuis la deuxième turbine (152) vers la troisième turbine (153), (G) un premier dispositif de raccordement (171), mis au point de telle manière qu'un premier flux massique partiel (171a) du fluide de travail peut être prélevé sur la première conduite de fluide (161) ou peut être amené à la première conduite de fluide (161), et (H) un deuxième dispositif de raccordement (172), mis au point de telle manière qu'un deuxième flux massique partiel (172a) du fluide de travail peut être prélevé sur la deuxième conduite de fluide (162) ou peut être amené à la deuxième conduite de fluide (162). L'invention concerne en outre une installation de turbines (100) comprenant un tel système de turbines (110), ainsi qu'un procédé permettant de faire fonctionner une machine de travail (120).
