Application of coflow premixed flame for generating aggregate silica particles and its limitation

This paper reports the geometrical characteristics and growth of aggregate silica particles generated in a premixed flame using thermophoretic sampling, light scattering technique, dynamics modeling only for flat condition. The area equivalent size morphology thermophoretically collected were analyzed through images taken from transmission electron microscope. particle stream flames was visualized planar technique. Light intensity at 90° an Ar-ion laser (wavelength, 514 nm) monitored various conditions. results under one-dimensional assumption indicated that grew as height above burner increased. Aggregate produced equivalence ratios showed different levels OH-species. OH-related species increased ratio decreased, which implies high is recommended to produce pure particles. In this study, purest 11.4, among others. Our study helps determine condition best terms quality and/or quantity by coflow burner.
