Title
(EN) AXIAL TURBINE WITH TWO SUPPLY LEVELS
(FR) TURBINE AXIALE À DEUX NIVEAUX D'ALIMENTATION
Abstract
(EN)
Axial turbine (100) with two supply levels for the expansion phase of a working fluid in a thermodynamic vapor cycle or in an organic Rankine cycle comprising a shaft (2), a plurality of rotor blade arrays (R1-Rn) and corresponding support disks (21, 22), a plurality of stator blade arrays (S1-Sn), further comprising a first inlet opening (5) and a second inlet opening (7'). The second volute (4) is positioned inside the first volute (3), the working fluid of the second supply level reaching upstream of a stator blade (S2, S3... Sn) any subsequent to the first stage, and the vapor flow of the first supply level and that of the second supply level are conveyed so as to be substantially parallel to each other according to an axial direction upstream of a stator blade (S2, S3... Sn).
(FR)
L'invention concerne une turbine axiale (100) à deux niveaux d'alimentation pour la phase d'expansion d'un fluide thermodynamique dans un cycle de vapeur thermodynamique ou dans un cycle de Rankine organique. Ladite turbine comprend un arbre (2), une pluralité de réseaux d'aubes de rotor (Rl-Rn) et des disques de support correspondants (21, 22), une pluralité de réseaux d'aubes de stator (Sl-Sn), comprenant en outre une première ouverture d'entrée (5) et une seconde ouverture d'entrée {!'). La seconde volute (4) est positionnée à l'intérieur de la première volute (3), le fluide thermodynamique du second niveau d'alimentation atteignant en amont d'une aube de stator (S2, S3... Sn) de n'importe laquelle subséquente au premier étage, et le flux de vapeur du premier niveau d'alimentation et celui du second niveau d'alimentation sont transportés de manière à être sensiblement parallèles l'un à l'autre selon une direction axiale en amont d'une aube de stator (S2, S3... Sn).
