Abstract: PURPOSE: To ensure stability of a shape of a turbine inlet, and prevent thermal deformation by providing each guide part for allowing only expansion and contraction in the radial direction on each inner and outer shell of the turbine inlet for guiding a high temperature gas from a combustion chamber to a turbine part. CONSTITUTION: A gas turbine 1 is provided with a turbine part 2, a combustion chamber 4, and a ring shaped turbine inlet 3 disposed between the turbine part 2 and the combustion chamber 4. The turbine inlet 3 guides a high temperature gas from the combustion chamber 4 to the turbine part 2, and is restricted outward by an outward shell 7 and inward by an inward shell 8. In this case, respective guide parts 12, 13 in many radial directions allocated uniformly in respective circumferential direction, are arranged on the outward shell 7 and/or the inner shell 8. Each of guide parts 12, 13 obstruct one or both sliding of each shell 7, 8, and allow expansion and contraction of a radial direction.

Abstract: PROBLEM TO BE SOLVED: To manufacture a dissolvable non-cooling lining for a combustion chamber from ceramic elements. SOLUTION: In a ceramic lining for a combustion chamber composed of at least one wall plate 3 having at least one penetrating opening 6 and manufactured from a high temperature resistant ceramic and a fixing member for each opening 6, the fixing member 4 is disposed in a metallic holding apparatus 5 fixed to the metallic support wall 1 and a head of the fixing member 4 is located in the openings 6 and further an insulating layer 2 is disposed between the metallic support wall 1 and the ceramic wall plate 3. The fixing member comprises high temperature resistant ceramic. The wall plate is protruded toward the metal support wall in a region of the openings, and the fixing member is combined with a specific holding apparatus resiliently.

Abstract: PURPOSE: To functionally integrate a seal device and a guide device of an outer shell at a turbine inlet into one position in a gas turbine provided with a turbine and a combustion chamber. CONSTITUTION: A outer shell 14 is jointed to a nozzle retainer 3 through a seal device 20 operable at an end part facing the turbine. The seal device 20 guides and restricts the movement of the outer shell 14 caused by heat in the axial and radial directions.
