摘　　要：通过对全烟气再循环条件下由开放射流与全扩散射流组成的双旋流配风器的燃油燃烧器进行数值模拟,由试验结果得出了计算条件下炉膛的烟气最高温度小于1 500K;负荷变化时,炉膛烟气最高温度几乎不变,最高温度区域随负荷降低而减小。Through numerical simulation of double swirl air distribution oil-fired combustion equip-ment with open jet and full diffused jet under condition of full flue gas recirculation,the experiment re-sult calculates the highest temperature is low than 1500K.When load changes,the highest tempera-ture of furnace flue gas is almost fixed and the highest temperature zone reduces with load reduces.

关 键 词：开放射流 全扩散射流 双旋流燃油燃烧器 热力NOx和燃料NOx
