【摘要】 在内径32 mm、高1 100 mm的流化床焚烧炉实验台上,进行含苯胺(C6H5NH2)有机废液焚烧实验研究,得出苯胺中有机氮转化为NOx的转化率与温度、过剩空气系数α以及含氮量之间的变化规律.结果表明:随着温度的升高,有机氮转化为NOx的转化率逐渐降低;当α>1.0~1.1时,随着α的增加,有机氮转化为NOx的转化率增加,其中800~850℃下增加幅度较小,900~950℃下增加的幅度较大,当α<1.0时,有机氮转化为NOx的转化率迅速降低,在α=0.8时有机氮转化为NOx的转化率降到5%以下;随着废液中有机氮含量的增加,有机氮转化为NOx的转化率降低,且受温度影响很大.更多还原

【Abstract】 The characteristic of NO_x emission from the incineration of organic wastewater containing aniline（C₆H₅NH₂） from lab was investigated at 800⁹50 ℃ in a bench scale bubbling fluidized bed.The results show that the conversion of organic N to NO_x is influenced by the temperature,the excess air and the content of organic nitrogen in wastewater.The conversion of N-NO_x decreases with increasing in temperature.When excess air coefficient is larger than 1.0～1.1,the conversion of N-NO_x increases with increasing in excess air coefficient,while when excess air is less than 1.0,the conversion of N-NO_x decreases rapidly to 5 percent at the excess air coefficient of 0.8.With the increase of aniline concentration in wastewater,the conversion of（N-NO_x） decreases,and is strongly dependent on temperature.更多还原
