    摘要: The guide vane of a gas turbine comprises a blade having an outer platform connectable to a guide vane carrier or gas turbine casing, and at the opposite end an inner platform that carries a cover plate. The inner platform has a dovetail housing to which the cover plate is connected. The method for replacing the cover plate consists in separating the cover plate from the inner platform by cutting along the profile of the dovetail housing, then making the cover plate to slide out of the dovetail housing, thus inserting a new or refurbished cover plate into the dovetail housing.

    摘要: A gas turbine includes a supporting structure which concentrically surrounds a hot gas path and is shielded with respect to the hot gas path by an annular heat shield (15′), which heat shield (15′) includes a multiplicity of segments which are arranged one behind the other in a circumferential direction and which in each case butt against one another in the circumferential direction so as to form a gap, seals (16′), being arranged for sealing off the gaps between the segments butting against one another, the seals having thin elongate sealing strips (23), which are accommodated in corresponding sealing slots (19), delimited transversely with respect to the longitudinal direction by a wall (25), in the mutually opposite end faces of the segments of the heat shield (15′) which butt against one another. Vibrationally-induced rubbing through of the wall is inhibited or prevented by the frictional surface between the wall (25) and the sealing strips (23) being markedly enlarged with respect to the end face (22) of the sealing strip (23).

    摘要: For preparing a gas stream cleaned from dust and dirt particles, a device is proposed in which an outflow channel (2) for cleaned medium has at its mouth in an inflow channel (1) an extension element (4), which projects into the inflow channel. A cover element (6) covers an end inflow aperture (4a) of the extension element. In an embodiment of the invention, the extension element (4) has lateral inlet apertures (5). The cover element (6) is preferably constituted hood-shaped, and has axial extension elements (6a), which at least partially cover the extension element (4) in the axial direction, and advantageously extend over the lateral inlet apertures. The stream entering the outflow channel (2) for cleaned medium must overcome strong flow deflections, so that particles with a low flow following ability cannot get into this channel. Further outflow channels (3) for conducting the remaining dust-laden medium are arranged substantially flush with the wall (7) of the inflow channel.
