Summary:PURPOSE:To reduce a gas leak by detecting a clearance at the tip of a moving blade and regulating the temperature and the flow amount of cooling air separately. CONSTITUTION:A part of delivered air from an air compressor 12 is introduced to inter-coolers 8 and 8'. The air with the temperature thereof regulated in the inter-cooler 8 is fed to a casing via a flow control valve 17. The air supplied to the inter-cooler 8' is regulated in temperature and flow amount therein and fed to a rotor. The temperature and flow of cooling air running to the rotor and the casing are separately controlled, thereby enabling a minimum setting value for clearance at a moving blade tip and the reduction of a gas leak.
