Title
(EN) COMBINED CYCLE ELECTRIC POWER GENERATION UNIT WITH A GAS TURBINE AND A MULTIMODULE STEAM TURBINE
(FR) UNITE DE PRODUCTION D'ENERGIE ELECTRIQUE A CYCLE COMBINE COMPORTANT UNE TURBINE A GAZ ET UNE TURBINE A VAPEUR A PLUSIEURS MODULES
Abstract
(EN) A combined cycle electric power generation unit with a gas turbine (6), a multimodule steam turbine (1, 2) and an electric generator (11) mounted on the same line of shafts via rigid couplings (28, 29, 31), said gas turbine (6) being axially translatable and attached to a movable abutment (27), wherein the stationary portions of the gas turbine (6) and the first steam turbine module (1) are interconnected via at least two connecting rods (32), said connecting rods (32) and the ends of the rotors of the gas turbine (6) and the first steam turbine module (1) are enclosed in a chamber (33) filled with a heat-conducting fluid, and the ends facing the stationary portions of the last two steam turbine modules (1, 2) are each connected to a fixed point (34, 35).
(FR) Unité de production d'énergie électrique à cycle combiné comportant, montés successivement sur une même ligne d'arbres par l'intermédiaire d'accouplements rigides (28, 29, 31), une turbine à gaz (6), une turbine à vapeur à plusieurs modules (1, 2) et un générateur électrique (11), la turbine à gaz (6) étant montée mobile en translation axiale et fixée à une butée mobile (27), caractérisée en ce que les parties statiques de la turbine à gaz (6) et du premier module (1) de la turbine à vapeur sont reliées entre elles par au moins deux bielles (32), en ce que lesdites bielles (32) et les extrémités des rotors de la turbine à gaz (6) et du premier module (1) de la turbine à vapeur sont enfermées dans une enceinte (33) remplie d'un fluide conducteur de la chaleur et en ce que les extrémités en regard des parties statiques des deux derniers modules (1, 2) de la turbine à vapeur sont reliées chacune à un point fixe (34, 35).
