Abstract

La turbine (20) axiale multi-étagée, pour la détente de fluide organique dense à bas point d'ébullition, comporte : - un rotor (R1 à R4) pour lequel des paliers et des étanchéités sont positionnés à chaque extrémité, - des étages (215 à 230) amovibles comportant, chacun, un distributeur fixe et une roue mobile fixée à l'arbre de rotation, - chaque roue étant composée d'un disque surmonté d'ailettes et d'une couronne, l'ensemble de la roue étant intégralement usiné dans la masse à partir d'un seul bloc, - chaque étage présentant en sortie, un écoulement subsonique dont la direction présente un angle inférieur à 15° par rapport à l'axe du rotor ; - le nombre d'étages étant supérieur ou égal à deux.The multi-stage axial turbine (20), for the expansion of dense organic fluid at low boiling point, comprises: - a rotor (R1 to R4) for which bearings and seals are positioned at each end, - stages (215 to 230) removable comprising, each, a fixed distributor and a movable wheel fixed to the rotation shaft, - each wheel being composed of a disc surmounted by fins and a crown, the whole of the wheel being fully machined in the mass from a single block, - each stage having at the outlet, a subsonic flow whose direction presents an angle of less than 15 ° with respect to the axis of the rotor; - the number of floors being greater than or equal to two.
