ULTRASONIC JET BURNER

A supersonic jet burner by the present invention comprises a cylindrical burner main body 1 having a combustion path on its central axis; a fuel filling nozzle unit 3 arranged at a base of the main body, wherein a tip nozzle of the nozzle unit 3 is arranged to face a base of the combustion path; a first combustion chamber 4 formed ahead of the nozzle unit; a plurality of first air ejecting ports A circularly arranged so as to surround the first combustion chamber and facing to the combustion path so as to form a swirling combustion flow section X; a circularly arranged plurality of second air ejecting ports B capable of ejecting whirling flows of high pressure air heated in a high pressure air flowing passage 15 formed around the outer periphery of the main body 1 so as to form a whirling high temperature combustion section Y; a second combustion chamber 21 arranged ahead of the whirling high temperature combustion section Y; a narrowly drawn shock wave conversion section Z for raising a flow rate of combustion gas up to more than the sonic speed formed as the tip of the cylindrical main body 1.
