摘要

PROBLEM TO BE SOLVED: To provide a premixing combustor having an improved durability by cooling a combustion chamber liner with a comparatively simple structure. SOLUTION: The liner 2 to form a combustion chamber of the premixing combustor wherein fuel and combustion air are premixed and the premixture is burnt in the combustion chamber consists of a cylinder part 21 and an enlarged shoulder part 20. A number of fine holes for inflow of air formed approximately in parallel to the central axis of the cylinder part 21 are formed in the wall surface of the enlarged shoulder part 20.
