Abstract: A solar thermal power generation facility is provided with turbine bypass piping (74) which makes some of compressed air from a compressor (10) bypass a turbine (20), a turbine bypass valve (75) which adjusts the flow rate of the compressed air flowing through the turbine bypass piping (74), and a control device (80) which controls the rotational torque of a turbine rotor (21) by opening the turbine bypass valve (75) before a rotor rotational speed reaches a rated rotational speed in a speeding-up process of the rotor rotational speed by a start-up device (60) and adjusting the flow rate of the compressed air that is made to bypass, by the turbine bypass valve (75). The control device (80) instantaneously fully closes the turbine bypass valve (75) at the time of incorporation in which a power generator (50) is connected to an electric power system (S).

Abstract: In this method of preventing deformation in a turbine casing of a gas turbine, in a turbine casing 10 there is arranged a buffer tank 30. In this buffer tank 30 there are formed a stagnation part agitation air opening 52 which ejects part of the air from an air compressor 21 as stagnation part agitation air Ga2 toward a stagnation part 19 within the turbine casing, and an overall agitation air opening 51 which ejects overall agitation air Ga1 for agitating gas held in an upper space within the turbine casing. In the buffer tank 30 there is provided a partition wall 36 with through holes 53 formed therein serving to resist air from the air compressor 21, in order to make the ejection speed of the overall agitation air lower than the ejection speed of the stagnation part agitation air.
