ABSTRACT:
A power generation system comprising a gas turbine, a steam turbine and a generator are mounted on a foundation in substantial axial alignment and connected by a single shaft. A thrust bearing is located on the shaft in one of the gas turbine and steam turbine. Whichever of the gas turbine and steam turbine contains the thrust bearing is flexibly secured to the foundation, and the other of the gas turbine and the steam turbine, as well as the generator, are rigidly secured to the foundation. A pair of rigid tie rods also extend between the steam and gas turbines, parallel to the shaft, to maintain a predetermined axial distance between the turbines, while allowing relative movement in a plane perpendicular to the shaft.
