PURPOSE:To improve the load follow-up property and controllability of a system by detecting that the compressed air quantity fed from a turbine compressor is lacking and applying the correction value to the pressure preset value to increase the pressure at the turbine inlet side of the turbine compressor. CONSTITUTION:The system bypass air flow detection value (k) detected by a flow detector 20 is fed to an auxiliary burner set pressure correction value arithmetic unit 17, a correction value (l) is added to the auxiliary burner pressure set value (b) to obtain the corrected auxiliary burner pressure set value (m). This auxiliary burner set pressure correction value arithmetic unit 17 applies the correction value (l) to the auxiliary burner pressure set value (b) to increase the pressure at the turbine inlet side of a turbine compressor when the system bypass air flow detection value (k) becomes smaller than the preset value. The air flow of the compressor is thereby increased, the phenomenon that the air quantity of the system is lacking is prevented, and the load follow-up property and controllability of the system can be improved. |
