PURPOSE:To improve thermal efficiency of a gas turbine combustor and reduce Nox, by performing follow up combustion of the catalytic combustor in accordance with a load of a turbine. CONSTITUTION:A total quantity of fuel of a gas turbine catalytic combustor is obtained by operating a flow control valve 28 provided to a fuel main pipe 9 and controlling a flow of fuel flowing in the pipe 9 through a signal from a gas turbine output signal setter 32. Such flow controlled fuel in a fuel main pipe 9 is distributed to the respective catalytic combustors by operation of opening and closing valves 16-19 opened and closed by a gas turbine output signal 33. In this way, the fuel, whose flow is controlled in accordance with a load of a gas turbine, is further distributed to the catalytic combustor in accordance with the load of the turbine, and catalytic combustion is performed in accordance with the load of the gas turbine.
