摘　　要：在实验室规模的热态流化床试验台上 ,进行了含 5 %己二胺有机废液的焚烧实验研究 .在 70 0— 90 0℃范围内 ,研究温度及空气过剩系数对NOx 沿床高的变化规律 ,以及它们对NOx 排放浓度的影响 .实验结果表明 ,沿高度方向上NOx 浓度逐渐降低 ,并且存在NO2 浓度大于NO浓度这一有趣现象 .在 90 0℃下氧量增加有利于密相区NO、NO2 浓度的降低 ,说明在有氧条件下NH2 促进NOx 的还原 ,在不同空气过剩系数下稀相区出口NOx 几乎为零 ,表明 90Experiments were conducted to investigate NO x concentration profiles along bed height and the influences of temperature and excess air on NO x emission in the temperature range from 700℃ to 900℃, when waste water containing 5% hexamethylenediamine incinerated in a bench scale fluidized bed. The results indicate that NO x concentration profiles decrease progressively with bed height and the concentration of NO 2 is larger than that of NO along bed height except in the freeboard at 900℃, where NO, NO 2 concentrations are zero. Temperature and excess air play significant role on NO x emission. With increasing in temperature the NO x emission decreases very rapidly, and decreases to zero at 900℃. With increasing in excess air, NO x emission increases considerably at 700℃, but it is almost independent of excess air at 800℃, and at 900℃, NO x emission is almost zero indicating that NH 2 from NH 2(CH 2) 6NH 2 has strong effect on de NO x .
