BURNER FOR PRODUCTION OF INORGANIC SPHERICALIZED PARTICLE
摘要
<p>A burner for production of inorganic sphericalized particles comprising a raw material powder supply channel for supplying of raw material powder with the use of oxygen or an oxygen-enriched air as a carrier gas; a powder dispersion plate with a multiplicity of small perforations fitted to a downstream end of the raw material powder supply channel; a raw material dispersion chamber defined by a dispersion pipe fitted to a downstream end of the powder dispersion plate; a fuel supply channel disposed around the outer circumference of the raw material powder supply channel; an oxygen supply channel disposed around the outer circumference of the fuel supply channel; and a combustion chamber disposed downstream of the raw material dispersion chamber, the combustion chamber having its inside diameter increasing along the downstream direction and communicating with the fuel supply channel and oxygen supply channel.</p>
