COMBUSTION BURNER FOR SULFUR, COMBUSTION FURNACE INCLUDING THE SAME, AND METHOD FOR BURNING SULFUR

摘要

PROBLEM TO BE SOLVED: To provide a combustion burner for sulfur which is capable of suppressing generation of unburned sulfur and maintaining combustion over a long time when burning a slurry containing sulfur or melted sulfur.SOLUTION: A combustion burner 10 for sulfur has a triple-pipe nozzle structure including: a sulfur supply nozzle 1 to supply a sulfur slurry S or the like; an air supply nozzle 2 that is disposed outside the sulfur supply nozzle 1 in a concentric fashion and supplies air A to a gap between the sulfur supply nozzle 1 and the air supply nozzle 2; and a fuel gas supply nozzle 3 that is disposed outside the air supply nozzle 2 in a concentric fashion and supplies fuel gas G to a gap between the air supply nozzle 2 and the fuel gas supply nozzle 3.
