Abstract
An electricity generating unit having a combined cycle, and comprising, mounted in succession along a common line of shafts via rigid couplings (28, 29, 31), a gas turbine (6), a steam turbine having a plurality of modules (1, 2), and an electricity generator (11), the gas turbine (6) being mounted to move in axial translation, and fixed to a moving abutment (27), said electricity generating unit being characterized in that the stator portions of the gas turbine (6) and of the first module (1) of the steam turbine are connected together via at least two links (32), in that said links (32) and the ends of the rotors of the gas turbine (6), and of the first module (1) of the steam turbine are enclosed in an enclosure (33) filled with a heat-conducting fluid, and in that each of the facing ends of the stator portions of the last two modules (1, 2) of the steam turbine is connected to a respective fixed point (34, 35).
