To control instability of combustion positively under a simple and functionally little precondition by employing a fluidic method for modulating fuel supply.
A premixing burner 17 in a combustion system 10 is constituted as a double cone burner where gaseous fuel is jetted from nozzles on the opposite sides and mixed with required combustion air. The premixing burner 17 is supplied with fuel from two separated fuel pipes 15, 16 which are supplied with fuel from a common fuel inlet 12 through a fluidic member 11. The fuel inlet 12 is branched into two Y-shaped fuel outlets 31, 32 in the fluidic member 11 on the downstream side of a constricted part. The fuel outlets 31, 32 are coupled with the fuel pipes 15, 16. The fluidic member 11 operates based on the principle of Prandtl diffuser and Coanda effect.
