ABSTRACT:
A control apparatus for a gas turbine having an air flow control valve for controlling the flow rate of combustion air in an air flow passage from a compressor to the gas turbine, includes an air velocity or flow sensor arranged in the vicinity of the air flow control valve. A control unit operates to control the opening of a fuel flow regulation valve and/or an air flow control valve on the basis of a signal from the air velocity or flow sensor, thereby to control the air fuel ratio in a combustion section of the gas turbine.
