PROBLEM TO BE SOLVED: To promote ignition by gathering fine particles near a spray nozzle, and to promote mixing of sprayed particles and combustion air by raising momentum of spray.SOLUTION: Mixed fluid passages 18, 19 in which a mixed fluid of a fluid to be sprayed and a spraying medium flows are disposed opposite each other near a jetting hole 2. A spray nozzle sprays from the jetting hole 2 the mixed fluid atomized by making the mixed fluid collide. For instance, openings of passages 14, 15 of the spraying medium connected to passages 10, 11 of the fluid to be sprayed are located at both end sides in the width direction perpendicular to the flow direction of the fluid to be sprayed. |
