Abstract
A combustor of a gas turbine includes: a shell made of metal; a liner located inside the shell and made of a ceramic matrix composite, the liner including an inner surface defining a combustion chamber, an outer surface facing a side opposite to a side where the combustion chamber is located, and at least one cooling hole that is open toward the combustion chamber, and a cooling chamber defined between the shell and the liner. The shell includes a tubular shell main body and a seal wall structure projecting from an inner surface of the shell main body toward the liner.

A combustor of a gas turbine,
- the combustor comprising:
- a shell including metal, the shell including an opening into which compressed air is introduced;
- a liner located inside the shell and including a ceramic matrix composite, the liner including
- an inner surface defining a combustion chamber,
- an outer surface facing a side opposite to a side where the combustion chamber is located, and
- at least one cooling hole that is open toward the combustion chamber;
- and
- a cooling chamber defined between the shell and the liner, wherein
- the shell includes
- a tubular shell main body and
- a seal wall structure projecting from an inner surface of the shell main body toward the liner;
- a tip of the seal wall structure is spaced apart from the outer surface of the liner;
- in a section of the cooling chamber when viewed in a circumferential direction of the combustor, the seal wall structure divides the cooling chamber into cavities
- one of the cavities is interposed between the cooling hole of the liner and the opening of the shell,
- the opening of the shell overlaps the cooling hole of the liner, viewed from a direction in which the seal wall structure protrudes.
