摘　　要：对自身预热式Ⅰ型辐射管烧嘴结构及NO_(x)生成原因进行介绍,通过热态试验测试对烧嘴降低NO_(x)排放的方法进行分析,得出不同烟气回流率对烧嘴降低NO_(x)排放的影响效果。分析MnO_(x)模式原理,得出烧嘴高温应用MnO_(x)燃烧模式对NO_(x)排放的抑制作用。对比两种不同直径辐射管高温应用NO_(x)排放指标,得出烟气回流和MnO_(x)技术叠加使用时烧嘴高温NO_(x)排放指标。Introduce the structure of the self-preheating type Ⅰ radiant tube burner and the reasons for NO_(x) generation,and analyze the method of reducing NO_(x) emissions from the burner by the method of thermal experiment. We get the effect of different flue gas recirculation rates on the burner’s NO_(x) emission reduction, and we also explain the principle of the MnO_(x) mode, conclude that the burner high temperature application on MnO_(x) combustion mode can inhibit NO_(x) emission. We also compare the NO_(x) emission of two different diameter radiant tubes for high-temperature applications,and get the high temperature NO_(x) emission index of the burner when flue gas recirculation and MnO_(x) technology are used in combination.
