Experimental study on the Formation and Growth of Silica Particles in $H_2/O_2$ Diffusion Flame by Electro-Spraying Method and Evaporation

$H_2/O_2$확산화염에서 전기수력학적 방법과 증발기에 의해 발생된 입자의 성장 비교에 관한 실험적 연구

Flame aerosol synthesis technology refers to the formation of fine particles from gases in flame and is widely used in practical materials processing. In this paper, an experimental investigation was performed on growth of the silica particles that were generated in $H_2/O_2$ Diffusion Flame by the direct injection or TEOS using Electro-spraying method. in this flame aerosol synthesis, four main parameters or nos interaction (flame temperature, residence time or particle in flame, TEOS flow rate, applied voltage) for particle generation and growth was investigated along the axial direction above the burner. A fairly monodisperse non-aggregated particles were successfully obtained.
