Abstract: PURPOSE: A droplet generation system and a method are provided to generate a nano particle of a composition which is determined by gas and liquid received in a fusing stage. CONSTITUTION: A droplet generation system(10) comprises a first nozzle structure(20) and a second nozzle configuration(30). The first nozzle structure receives liquid(15) and gas(16) under pressurization in a controllable feed ratio, and forms an intermediate stream which is a mixture of dispersed phase liquid and gas by mixing the liquid and the gas. The second nozzle is connected to receive the intermediate stream from the first nozzle structure. The second nozzle comprises a valve mechanism having more than one controllable operating parameter in order to emit a droplet stream of the liquid. An average size of the droplet changes according to a controllable feed ratio of the gas and the liquid. A flux of the droplet stream changes according to a controllable operating parameter of the valve mechanism.
