The system comprises a series of heaters arranged in cascade and fed with steam from drawoffs at pressures which progressively decrease from the steam boiler side to the condenser side of the plant. In order to improve the efficiency of the plant with which the system is associated, the system comprises a plurality of biphase turbines arranged in cascade. The first of the turbines is fed from the drain of the heater at the highest pressure and the following turbines are each fed at least in part with the outlet liquid of the biphase turbine preceding it. These biphase turbines produce mechanical energy by recovery of the kinetic energy of the condensates of the heaters feeding them.
