PURPOSE:To make the cooled surface are smaller and facilitate the replacement of damaged parts as well as maintenance work by forming a cylindrical outer annular part with multiple circumferentially divided arc-shaped outer annular elements, forming a cylindrical inner annular part with inner annular elements while a ring form combustion chamber is provided between the outer and inner annular parts. CONSTITUTION:An annular type combustor liner 7 has a cylindrical outer annular part 10 and an inner annular part 11 coaxially, and an annular combusting chamber is formed between the outer annular part 10 and inner annular part 11. The outer annular part 10 comprises multiple outer annular elements 12 made of sheet metal which are curved in arc and mutually connected in the circumferential direction, and the inner annular 11 comprises multiple inner annular elements 13 which are similarly shaped and circumferentially connected. Since the combusting chamber is formed in an annular combusting chamber between the outer and inner annular parts which respectively comprises multiple annular elements, the cooling surface area can substantially be reduced. Further, if a part of the combustor is damaged, only those annular elements which are damaged need to be replaced, thereby facilitating the maintenance work.
