ABSTRACT:
A turbine plant, in particular a steam-turbine plant, includes at least two turbine sections, each having a turbine rotor extending along a main axis and an inner casing accommodating guide blades. At least one inner casing is displaceable in axial direction and a thermally expanding thrust element is provided for an axial displacement. The trust element has first and second expansion components connected to one another by a coupling component. The coupling component mechanically and/or hydraulically produces an axial displacement of the second expansion component which is greater than a thermal expansion and/or axial displacement of the first expansion component. A thrust element for reducing different axial expansions between two components expandable independently of one another along a main axis, is also provided.
