摘要： PROBLEM TO BE SOLVED: To reduce the consumption of high-calorie gases such as a coke oven gas (COG) during the running of a gas turbine, and prevent the gas turbine from being shut down due to clogging of a pilot line, trouble with a compressor for compressing the high-calorie gas, or the like, thereby providing improved reliability for the gas turbine.SOLUTION: Upon starting the operation of the gas turbine 11, a combustor 17 is supplied with high-calorie fuel and low-calorie fuel through both a first fuel supply system 31 and a second fuel supply system 32, the first fuel supply system supplying the high-calorie fuel to a first nozzle constituting the combustor 17, the second fuel supply system supplying the low-calorie fuel to a second nozzle constituting the combustor 17. When reaching the output at which the gas turbine 11 can be continuously operated only on the low-calorie fuel, supplying the high-calorie fuel to the combustor 17 is stopped so that only the low-calorie fuel is supplied to the combustor 17.
