Abstract:
1. A wall of a gas turbine, comprising: a plurality of wall sections connected in the direction of a set of blades in the gas turbine and forming a wall surface having a substantially circular cross section, the wall sections being fixed to an outer end or an inner end of the set of blades in the gas turbine, or being positioned to interpose a predetermined space between the outer end of the set of blades and forming a passage wall for high temperature gas together with a blade surface of the respective blade; and a plurality of gas flow restricting devices positioned in gaps formed between the wall sections, respectively, and configured to restrict the high temperature gas from flowing in the gaps along axial and radial directions of the gas turbine, wherein the plurality of wall sections have side end wall surfaces in the gaps, and the side end wall surfaces have blowoff openings for blowing cooling air into the gaps.
