Zusammenfassung:	PROBLEM TO BE SOLVED: To secure both characteristics of "reduction in NOx" and "stable combustion" in a premixed combustion device for burning a premixed gas obtained by mixing air and fuel in advance.SOLUTION: A stationary sound field is formed by a stationary sound field forming means (speaker 41, 42) within a cylindrical combustion chamber 30 and by applying the stationary sound field to a flame within the cylindrical combustion chamber 30, the flame is controlled by using a secondary flow in the direction vertical to the direction in which a pressure wave generated at the loop of speed vibration of the stationary sound field travels and wrinkles formed in the flame.
