PROBLEM TO BE SOLVED: To provide a spray nozzle which sprays a pressurized gas flow mixed with particulates, can suppress dust caused by the scattering of the particulates, and can maintain a high-speed, long-distance jet flow by controlling the damping of the energy of the gas jet flow mixed with the particulate ejected from the ejection port of the nozzle. SOLUTION: An inside nozzle 2 is arranged inside an outside nozzle 1, the flow rate of an outside gas flow passing between the outside nozzle 1 and the inside nozzle 2 is made higher than the flow rate of an inside gas flow passing inside the inside nozzle 2, and a liquid spray nozzle 3 is arranged to encompass the outside nozzle 1.
