| 摘 要： | 以粉煤灰作为脱硫剂，采用固定床反应器，以模拟烟道气对粉煤灰的脱硫性能进行了研究，结果表明，在粉煤灰加入量为120g、含水率20％左右，对烟气流量为4L／min、SO2浓度为0．2％(体积浓度)的模拟烟道气脱硫效率可达最佳水平，脱硫率维持98％的时间可达到6min．粉煤灰对低浓度的二氧化硫脱硫效果较好，即比较适合用于锅炉烟道气脱硫． |

| Abstract: | The present research summarizes the status of fly ash,especially in flue gas de-sulfurization. Fly ash used as desulphurizer and its performance of desulphurization are studied by simulant flue gas within a fixed bed reactor.The results show that fly ash has a higher removal of sulfur dioxide from the simulant flue gas. The experiments indicate that about 98% of SO_ 2 separation can be achieved by the fly ash (120 g,water ratio 20%).When the flue gas flux is 4 L/min;the fly ash can maintain 6 minutes with a high sulfur capacity (98%).It is shown that fly ash with a better sulfur capacity and a low concentration of sulfur dioxide offers a proper application to boilers' desulphurization. |
