Each of the ducts comprises heat exchange means for each of the respective steam turbines. The hot exhaust gases from a gas turbine are passed in heat exchange with heat exchange means for each of steam turbine. Damper means for controlling the amount of hot exhaust gas passing into the respective heat exchange means for each steam turbine are also disclosed. In another embodiment of the invention, separate damper means for each of said respective heat exchange means for varying the amount of hot exhaust gas between each of said heat exchange means are provided. The inventive system provides high plant efficiency and excellent operating flexibility.
