Vane segment support and alignment arrangement for a combustion turbine.

摘要

In a combustion turbine having a rotor (32) with rows of turbine blades (34) mounted thereon and segmented vane structures (38) supported in the turbine between outer and inner cylinders (42, 44) adjacent to the first row of turbine blades (34) for directing the combustion gases onto the blades (34), the vane segments (38) of the segmented vane structures supported at their outer circumference by the outer cylinder (42) having at their radially inner ends radial slots (48) receiving eccentric pins (50) of bushing assemblies (52) which are angularly adjustably supported in openings (58) formed in support structure (56) associated with the inner cylinder (44), so as to permit adjustment of the inner support for the vane segments (38).
