Abstract
(EN)
The objective of the present invention is to provide an inorganic spheroidized particle production burner whereby even an inorganic powder having a large particle size distribution can be melted and spheroidized efficiently. The present invention provides an inorganic spheroidized particle production burner (1) comprising a raw material powder supply path for supplying an inorganic powder as a raw material powder, a first fuel gas supply path (3A) for supplying a first fuel gas, and a first combustion-supporting gas supply path (4A) for supplying a first combustion-supporting gas, wherein the raw material powder supply path has a first supply path (2A) extending in the axis direction of the burner (1), a first impact wall (2D) positioned at the leading end of the first supply path (2A), a plurality of second supply paths (2B) branching from the leading end of the first supply path (2A) and respectively extending in radial directions from the center of the burner (1), one or more dispersion chambers (2C) positioned at the leading end of each of the second supply paths (2B) and having a space that is wider than the second supply paths, and one or more raw material powder ejecting holes (2a) communicating with each dispersion chamber (2C).
