摘　　要：提出在燃气壁挂炉燃烧器(大气式燃烧器)火焰高温区布置火焰冷却体,降低烟气氮氧化物体积分数。采用试验方法,对安装火焰冷却体前后,壁挂炉排放烟气中一氧化氮、氮氧化物、一氧化碳的体积分数进行对比分析。安装火焰冷却体后,烟气中一氧化氮、氮氧化物体积分数有所降低,但一氧化碳体积分数有所提高。It is put forward that the metallic insert is placed in the high temperature zone of the burner flame in wall-mounted gas heater to reduce the volume fraction of nitrogen oxides in flue gas. A comparative analysis of the volume fractions of nitric oxide, nitrogen oxides and carbon monoxide in the flue gas from wall-mounted gas heater before and after placing the metallic insert is conducted by test methods. The volume fractions of the nitric oxide and nitrogen oxides decreased while the volume fraction of carbon monoxide increased after the metallic insert is placed.
