Patent ID: 8001790

Claim:
A gas turbine including a compressor that compresses air, a combustor that supplies a fuel to the air compressed by the compressor and burns the fuel to generate a combustion gas, and a turbine that is rotatably driven by the expansion of the combustion gas generated in the combustor, wherein a casing forming an outer shell of the gas turbine is supported on a foundation by a first supporting leg that supports the compressor side and a second supporting leg that supports the turbine side, wherein the first supporting leg supports the casing in a fixed condition with respect to the foundation, and a bias being provided in a seating face of the first supporting leg, and wherein the second supporting leg supports the casing in a movable condition so as to allow axial and radial deformation and displacement of the casing and is installed beforehand in an inclined manner at a predetermined angle θ to a surface orthogonal to an axis line of the casing when the gas turbine is in a stop condition.
