Burner for producing inorganic spheroidized particles, apparatus for producing inorganic spheroidized particles, and method for producing inorganic spheroidized particles

Abstract

One object of the present invention is to provide a burner for producing inorganic spheroidized particles which can efficiently melt and spheroidize even organic powder with a large particle size distribution. The present invention provides a burner for producing inorganic spheroidized particles, including; a raw material powder supply path configured to supply inorganic powder as raw material powder; a first fuel gas supply path (A) configured to supply a first fuel gas; and a first combustion-supporting gas supply path (A) configured to supply a first combustion-supporting gas; wherein the raw material powder supply path includes: a first supply path (A) configured to extend in an axial direction of the burner (); a first collision wall (D) configured to be located at the top of the first supply path (A); a plurality of second supply paths (B) configured to be branched from the top of the first supply path (A), and extend radially from the center of the burner (); one or more dispersion chambers (C) configured to be located at the top of the second supply path (B), and have a space in which the cross-sectional area is larger than the cross-sectional area in the second supply path (B); and one or more raw material ejection holes () configured to communicate with the dispersion chamber (C).
