In the above-mentioned gas turbine apparatus, since the turbine inlet temperature is kept constant and the turbine 4 is started, the turbine 4 may not be started when the starting torque of the turbine 4 decreases. Occurs.
The reduction of the starting torque of the turbine 4 occurs in the following cases, for example. 1) When the air compressor 3 is dirty and the air suction efficiency is reduced 2) When the suction temperature at startup is high 3) When the rotor blades of the turbine 4 are dirty 4) The equipment stops for a long time When the body of the turbine 4 gets cold

In such a case, the turbine 4 does not start up smoothly, but tries to start up 5 to 6 times, and finally starts up. However, for the turbine 4, the start-up failure is repeated many times. There is a problem that it is not preferable from the viewpoint of heat resistance and durability. On the other hand, it is difficult to quantitatively predict the decrease in the starting torque due to the contamination of the turbine 4 and the air compressor 3, and the degree of contamination varies depending on the installation environment. Therefore, it is conceivable to improve the start-up of the turbine 4 by replacing the motor for starting the turbine with one having a larger capacity, but with this, it is necessary to replace the reducer with a larger one. In this case, not only the cost of the device increases, but also the space necessary for modifying the turbine cannot be secured in some cases.
