An apparatus for disassembling and assembling a gas turbine combustor comprises a hand assembly for holding a combustor component of a gas turbine, an inserting and drawing section which supports the hand assembly and moves the same in parallel to a central axis of the combustor component and a retainer for securing the inserting and drawing section onto a casing which constitutes an outer section of the gas turbine.

Apparatus and method for disassembling and assembling gas turbine

Provided are a gas turbine multi-hole film-cooled combustor liner, which can be manufactured with improved accuracy in shape and position of cooling holes in a very short time, ensuring desirable buckling strength and satisfactory cooling performance. A planar flat member is curved to form a liner shell of a cylindrical shape, the cylindrical member is welded in the longitudinal direction thereof to form a cylindrical shell. Then a wavy configuration and a corrugated configuration are formed on the cylindrical shell by a hydro-bulging method, cooling holes are formed through the liner shell by laser drilling at or near wave crest portions of the wavy configuration of the liner shell, and inner rings are attached to the liner shell by resistance spot welding or vacuum brazing.
