Patent ID: 8297037

Claim:
A gas turbine comprising: a combustor including an inner cylinder and adapted to burn fuel to generate combustion gas; a combustor casing having a cylindrical shape around a rotational axis of the gas turbine to form a combustor chamber therein for housing the combustor therein; and the combustor casing defining a combustor insertion hole therethrough along a circumferential direction in a portion on a compressor side of the gas turbine to connect an inside portion and an outside portion of the combustor casing, wherein the combustor is inserted into or pulled from the combustor chamber through the combustor insertion hole, wherein the diameter of the combustor insertion hole in a direction orthogonal to a circumferential direction of the combustor casing is larger than the diameter of the combustor insertion hole in the circumferential direction of the combustor casing as viewed from a direction along with an axis of the inner cylinder, and when the combustor is inserted into the combustor insertion hole, the combustor insertion hole accommodates an entire external form of the combustor as viewed from the direction along the axis of the inner cylinder.
