摘要： A fuel ratio control method and a device therefor in a gas turbine combustor are provided in which supply ratio of pilot fuel to main fuel is appropriately maintained to thereby avoid unstable combustion, such as combustion vibration or misfire, and to realize a low NOx combustion. Fuel ratio control signal CSO is set corresponding to generator output L GEN put out by a generator output input unit 1. Pilot fuel ratio control is performed by correcting the fuel ratio control signal CSO corresponding to condition change in both or either one of combustion air and fuel. The condition change in the combustion air is at least one of changes in compressor on-line vane washing, ambient humidity, ambient pressure, etc. and the condition change in the fuel is a change in fuel component. The signal correction is also made by gas turbine deterioration factor or change rate in the generator output.
