A combined-cycle power system 4 comprising a first shaft 6 having a first group of components 12 coaxially mounted thereon, where the first group of components include a first steam turbomachine 14, a first gas turbomachine 16 and a reheat combustor 18; and a second shaft 8 separated from the first shaft with a second group of components 22 coaxially mounted thereon, wherein the second group of components include a second steam turbomachine 24, a second gas turbomachine 26 and a duct 29 fluidly coupling the second gas turbomachine and the reheat combustor such that the duct provides exhaust from the second gas turbomachine to the reheat combustor. Preferably there is also a third turbomachine coaxially mounted on the second shaft, where thesecond steam turbomachine includes an intermediate pressure steam turbomachine and the third steam turbomachine includes a high pressure steam turbomachine. |
