Patent ID: 8707671

Claim:
A fuel control apparatus for a gas turbine with a combustor being formed of at least two groups of pluralities of main nozzles for supplying fuel, with fuel supply valves being provided for each group of the main nozzles and supplying fuel to the main nozzles, the fuel supply valves being opened to change a supply amount of the fuel and being closed to prevent fuel from being supplied, and with an ignition detector detecting an ignition state of the combustor, the fuel control apparatus for a gas turbine comprising: a fuel controlling unit that, during ignition and acceleration but before loading of the gas turbine, is configured to control opening of the fuel supply valves of the main nozzles of all groups upon ignition of the combustor but before loading of the gas turbine, and after the ignition detector detects ignition of the combustor, while keeping the fuel supply valve of the main nozzles of at least one group excluding all groups open, closes the fuel supply valve(s) of the main nozzles of other group(s) during acceleration of the gas turbine.
