Abstract
A valve (6) for supplying the external air to the inside of an upper casing (5a) is provided to the upper casing (5a), and when the operation of a gas turbine is stopped, the external air is introduced from the upper casing (5a) to the inside of the casing (5). When the external air is introduced from the upper casing (5a), the upper casing (5a) is cooled to prevent thermal deformation of the casing (5).
