摘　　要：在流化床焚烧实验装置上进行含盐苯胺(C6H5NH2)废液的焚烧实验研究,用IMR-IMR2800P废气分析仪对焚烧尾气成分进行了在线监测,考察了焚烧工艺条件对NOx排放浓度的影响规律.结果显示:采用分级燃烧工艺和提高焚烧温度,可以降低NOx浓度;增大进料速率却导致NOx排放浓度的增加.当过剩空气系数(α)低于1.0时,NOx排放浓度随着α的增大急剧上升;大于1.1时,NOx排放浓度随α增加而减小.苯胺废液高温焚烧时添加氯化钠能降低NOx排放.The emission of NOχ from the incineration of salty aniline wastewater （ C6 H5 NH2 ） was investigated in a fluidized bed incinerator. The online flue gas was monitored using an IMR-IMR2800P flue gas analyzer. The effects of incineration processing conditions on the emission concentration of NOχ were studied. Results showed that the emission concentration of NOχ decreased by the staged - incineration process with increasing incineration temperature. By contrast, the emission concentration of NOχ increased with increasing feeding rate. When the excess air coefficient （α） was less than 1. 0, the emission concentration of NOx increased rapidly with α. However, the emission concentration of NOχ decreased when α〉 1.1. The emission concentration of NOχ was reduced in aniline wastewater incineration at high temperature using NaCl as an additive.
