GAS TURBINE AND METHOD OF OPENING CASING OF GAS TURBINE

摘要

A gas turbine 1 includes a combustor chamber 36 that houses a combustor unit 30 configured to include a combustor 39 that burns fuel to generate combustion gas for rotating a rotor 50, a turbine unit chamber that houses a turbine-unit rotor blade and a disk that rotate upon reception of the combustion gas, a combustor casing 31 that forms the combustor chamber 36, and a casing 60 that is configured to include the combustor casing 31 in which a divided portion on a surface orthogonal to a rotation axis RL of the rotor 50 is not formed in the combustor casing 31, but is formed in a portion on a downstream side of flow of the combustion gas lower than the combustor casing 31.
