PURPOSE:To promote stabilization of combustion characteristics and to improve a flame holding characteristics of a combustor, by increasing a swirling ability of an air flow, as well as rectifying a swirling flow of the air fed from an air controlling body into a uniform flow, by providing a revolving rectifier pipe, having an opening of which diameter is smaller than that of an air controlling body. CONSTITUTION:The air controlling body 6, having a plurality of revolving vanes in the connecting direction, is arranged to the top of the primary air passage, composed of an outer casing and an inner tube 1 and 2 inside of which an ultrasonic vibrator 10 is assembled. A revolving air rectifying tube 18, positioned in front of the atomizing surface 12 of the above-mentined ultrasonic vibrator 10, and having a throttled form of which diameter of opening is smaller than that of an air controlling body 6, is disposed at the surface of the front end of an air controllng body 6. To the rear end face of the air controlling body 6, a secondary air rectifying plate 19, having an opening of smaller diameter than that of the air controlling body 6, is provided. |
