Abstract

PURPOSE: To decrease the concentration of generated NOX, by forming a region where the powdered coal burns with greater air ratio and the other region where it burns with lesser air ratio after jetting from a nozzle.
CONSTITUTION: A jet opening 1 for the powdered coal is divided into two parts by a partition plate 4-1 mounted in the center, and at the exit of the divided paths partition plates 4-2, 4-3 are mounted aslant to lead the jetted flow of the powdered coal aslant. A reverse aslant jetted flow of the powdered coal is made in a next lower stage by partition plates 5-1W5-3. Then a burner nozzle can produced divided flame to form a combustion region with a greater air ratio and one with a lesser air ratio and the value of NOX generated from each region is made smaller resulting in a smaller NOX value as a whole.
