COMBUSTOR LINER

摘要

This combustor liner (12) has a double-walled cooling structure and comprises: an inner wall (30) which surrounds a combustion region (13) and in which effusion cooling holes (31) are formed; and an outer wall (20) provided so as to be separated from the inner wall (30) and in which impinge cooling holes (21) are formed. The inner wall (30) is configured from plate-like members (40) and has a support guide means (50) which guides each of the plate-like members (40) so that the plate-like members (40) can be inserted and extracted and which supports each of the plate-like members (40) in such a manner that the plate-like members (40) are separated from each other with gaps provided therebetween, the gaps being capable of absorbing the deformation of the plate-like members (40) caused by heat expansion.
