Abstract: front page image
(EN)A mixed flow turbine (1) for the expansion phase of steam thermodynamic cycles of an organic Rankine cycle provided with a first section (A) in which a first expansion of a main flow of working fluid takes place, in a substantially radial direction having at least one stator stage (S1, S2, … Sn) and at least one rotor stage (R1, R2, … Rn) of a second section (B) in which a second expansion of the main flow of the working fluid takes place in a substantially axial direction having at least one stator stage and at least one rotor stage and, between the first and the second section, with at least one angular stator stage (S4) comprising an array of angular blades which deflect the main flow of working fluid from the initial radial direction to a substantially axial direction. The turbine (1) is provided with means for injection (60) and/or means for extraction (70) of a second flow of working fluid, placed in proximity of the stator stage (S4).
(FR)L'invention concerne une turbine (1) à flux mixte destinée à la phase d'expansion des cycles thermodynamiques vapeur d'un cycle de Rankine organique, pourvue d'une première section (A) dans laquelle a lieu une première expansion d'un flux principal de fluide de travail, dans une direction sensiblement radiale ayant au moins un étage de stator (S1, S2, … Sn) et au moins un étage de rotor (R1, R2, … Rn) d'une seconde section (B) dans laquelle a lieu une seconde expansion du flux principal de fluide de travail dans une direction sensiblement axiale ayant au moins un étage de stator et au moins un étage de rotor et, entre la première et la seconde section, comportant au moins un étage de stator angulaire (S4) comprenant un réseau de pales angulaires qui dévient le flux principal de fluide de travail de la direction radiale initiale dans une direction sensiblement axiale. La turbine (1) est pourvue de moyens d'injection (60) et/ou de moyens d'extraction (70) d'un second flux de fluide de travail, placés à proximité de l'étage de stator (S4).
