PROBLEM TO BE SOLVED: To carry out fuel flow control with high readiness with respect to sudden change of a fuel flow desired value, fluctuation of fuel flow control valve post-pressure, and change of the number of ignited burners in a flow control system. SOLUTION: The flow control system is provided for controlling a flow control valve 6 provided in a piping supplying fluid. The number of ignited burners is calculated from a state of a limit switch per burner stop valve, a burner post-pressure is calculated from the number of ignited burners and a fuel flow set value, a valve flow coefficient of the flow control valve 6 is calculated by the burner post-pressure, an upstream side pressure of the flow control valve, and the fuel flow desired value, a valve opening of the flow control valve 6 is calculated on the basis of the calculated valve flow coefficient, and the opening of the flow control valve 6 is controlled by a signal adding a valve opening signal and a correction amount signal from the flow control system.
