Abstract
The present application relates to a fuel supply device for a gas turbine, which can supply a first fuel and a second fuel having a high combustion speed to a combustor of the gas turbine. In the present device, a first fuel supply line and a second fuel supply line are merged at a merging portion and are connected to the combustor via a mixing line. The second fuel supply line is provided with a first shutoff valve serving as a controlled object when the combustion state is switched from a single fuel combustion state to a mixed fuel combustion state, and a flow meter provided upstream of the first shutoff valve. The flow meter can output a detection value of a flow rate of the second fuel in order to calculate a mixing ratio of the first fuel and the second fuel for monitoring an operating state of the gas turbine.
