摘　　要：介绍了用粉煤灰、消石灰等制备成粒状脱硫剂 ,在固定床脱硫装置中对粒状脱硫剂的性能进行了实验 ,结果表明 :在固定床中粒状脱硫剂层厚度为 1.6m,空床气速为 0 .2 4 m/s,二氧化硫平均浓度约为160 0 mg/m3时 ,脱硫效率维持在 90 %以上的运行时间为 70 h,床层阻力约为 2 50 Pa/m.A highly effective pellet desulfurizing reagent prepared by pulverized coal ash and slaked lime was put to test in a fixed bed desulfur facility for its performance. Measurements indicated that under the conditions of 1 6 m in depth of the pellet reagent in the bed, 0 24 m/s of velocity of empty bed, 1600 mg/m\+3 of average SO\-2 conventration in the gas stream the efficiency of 90 % or more of sulfur removal was capable of maintaining 70 hours with the specific bed resistance to gas flow of about 250 Pa/m.
