Mounting arrangement for a single shaft combined cycle system

A power generation system comprising a gas turbine (12), a steam turbine (14) and a generator (16) are mounted on a foundation (22) in substantial axial alignment and connected by a single shaft (20). A thrust bearing (24) is located on the shaft in one of the gas turbine or steam turbine. Whichever...

Beschreibung
Zusammenfassung:	A power generation system comprising a gas turbine (12), a steam turbine (14) and a generator (16) are mounted on a foundation (22) in substantial axial alignment and connected by a single shaft (20). A thrust bearing (24) is located on the shaft in one of the gas turbine or 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 (34) 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.
