PROBLEM TO BE SOLVED: To provide a gas turbine plant capable of properly keeping a flue/air ratio. SOLUTION: The gas turbine plant comprises a gas turbine; a combustor to which fuel and air is supplied, and supplying combustion gas to the gas turbine; a fuel valve adjusting the fuel supply amount to the combustor; and a controller controlling the fuel valve. The combustor comprises a main combustor to which the supplied fuel and air is introduced; a transition pipe to which the combustion gas is supplied from the main combustor, and introducing the combustion gas to the turbine; and a bypass valve 15 controlled by the controller, and introducing a part of the supplied air into the transition pipe. The controller opens/closes the bypass valve 15 at an opening/closing speed corresponding to the output change of the turbine. COPYRIGHT: (C)2009,JPO&INPIT
