摘要： PROBLEM TO BE SOLVED: To prevent generation of thermal fatigue at the rear end of a tail pipe and to improve durability of the combustion cylinder.
SOLUTION: A combustor allows air compressed by a compressor and fuel to react to combust and introduces the generated combustion gas into the turbine through the combustion cylinder. Inside the side wall part 15 of the tail pipe 5b which is a part of the combustion cylinder, an airflow channel 20 is provided extending in the side surface direction of the side wall part 15. An inlet 21 of the airflow channel 20 is opened on the outer wall surface of the side wall part 15. An outlet 22 is opened on the rear end surface 16 of the tail pipe 5b.

摘要： PROBLEM TO BE SOLVED: To provide a branching structure of a conduit which improves strength and thermal fatigue life by relief of structural stress concentration and thermal stress.
SOLUTION: This branching structure of a conduit is formed by branching a branching pipe 2 at roughly right angles to the gas flow direction of a combustion apparatus tail cylinder 1 through which hot gas passes. In this structure, the radius of curvature of a branch corner portion 2a of the branching pipe 2 is increased as much as possible so that the hot gas may not separate. The branch corner portion 2a is provided with an internal cooling structure such as plate fins.
