<p>A turbine shroud assembly is disclosed, the shroud assembly including an outer shroud, at least one inner shroud attached to the outer shroud, and at least one discourager enclosed within the inner shroud. The discourager prevents the hot gas or steam in the turbine from having a direct line of access to the outer shroud. In one embodiment, one inner shroud is provided for the shroud assembly, with one discourager enclosed within the inner shroud, the discourager positioned offset from the inner shroud so as to extend past the inner shroud and into an inner shroud of a neighboring shroud assembly. In another embodiment, a plurality of inner shrouds are provided, each inner shroud enclosing a discourager, the discouragers being adjacent to each other within the inner shrouds and positioned offset from the inner shrouds so as to cover a gap between the inner shrouds.</p> |
