Abstract
Protection device for a stator of a turbine of the type comprising a series of annular sectors constrained to each other by means of connection means, each sector of the series of sectors comprises a first surface, suitable for contacting the stator which has at least one cavity for the cooling of the corresponding sector, and a second surface which faces a rotor of the turbine. In a rest configuration in which the turbine is not operating, the second surface of each sector has an axial section having an eccentricity with respect to the trace of the rotation axis of the turbine, whereas in an operating configuration in which the turbine is operating under regime conditions, the second surface of each sector has an axial section which is centered with the trace of the rotation axis of the turbine.
