An alignment tool includes a mounting flange, a support leg fixedly coupled to the mounting flange and cooperating with the mounting flange to define a partial annular ring that extends in an arc between 190 degrees and 350 degrees, and a second quantity of jack bolt pairs movably coupled to the support leg, each jack bolt pair arranged to engage one of the first quantity of seal segments. A third quantity of mounting fasteners is positioned to fixedly attach the mounting flange to the inner casing.

Tool for alignment of seal segments

A combustion section of a gas turbine includes an annular combustion chamber, a burner arrangement upstream of the combustion chamber, an annular compressor diffusor, and an annular combustion casing. The combustion casing has an outer section wall, an upstream section wall, and an inner section wall. The inner section wall extends along the rotor axis and is arranged between the burner arrangement and the compressor diffusor. A shielding is attached to the inner section wall at the side facing the rotor axis with a free space in-between at least. An outer diffusor wall of the compressor diffusor extends in axial direction up to the upstream half of the shielding.
