  • Patent number: 5281129
    Abstract: To provide a combustion apparatus and a controlling method therefor which are capable of preventing the flame-out and backfire of the flame of a premix burner and the increase of the NOx concentration attributable to the change of the calorific value of the fuel, the amount of air supplied to the premix burner is so controlled as to achieve a low NOx within the range in which the premix burner effects a stable combustion in accordance with the calorie of the fuel supplied to the combustion apparatus, and a change of the output of the combustion apparatus attributable to this control of the amount of air is compensated by the control of the amount of the fuel supplied to the diffusion burner.

  • Patent number: 4716719
    Abstract: A method of controlling fuel of a gas turbine provided with a two-stage combustion type combustor wherein the fuel of gas is fed to the combustor only through a primary fuel nozzle under a low-run of the gas turbine and through the both the primary fuel nozzle and a secondary fuel nozzle under a high-run of the gas turbine, and controlled by a fuel control valve according to a load signal, comprises measuring the flow rate of the fuel passing through the fuel control valve; controlling the fuel control valve according to the measured flow rate so that the flow rate will be constant or a scheduled value when the gas turbine reaches to a predetermined load; and switching fuel supply to the combustor from the primary fuel nozzle to through both the primary and secondary fuel nozzles while the fuel control valve is controlled according to the measured flow rate signal.
