| Abstract: | The detection technique for SO3 in sintering flue gas was established,including SO3 sampling device and determination method. The experimental results show that:Isopropanol with 80% of mass concentration is suitable to be used as absorbent;The recovery rate of the method is 95.79%-102.80% and the relative standard deviation is 0.46%-1.38%. By this detection technique,the interference caused by dust and SO2 in the sintering flue gas can be eliminated effectively. The detection technique is characterized by accuracy,reliability and facility and can be applied to SO3 determination in daily operation of sintering flue gas desulfurization device. |
