The results indicate that the mass size distribution of fly-ash particles in the inlet of the WFGD system is typically disturbed bimodally, the peaks are approximate at 1 and 3 μm. And the shape of particles is regular sphericity, the mass ratio of PM2.5 to PM10 is about 0.434. The total mass concentration is about 85 mg/m3. In the outlet of the WFGD system, the mass size distribution of fly-ash particles is also bimodal. The proportion of fine particles increased, the mass ratio of PM2.5 to PM10 is about 0.764. Some fine particles are conglutinated and formed irregular agglomerate. The total mass concentration is under 23 mg/m3, the removal efficiency of total particles is 74.5%. The size removal efficiency is decreased observably with the range of particle size decreasing.

结果表明，WFGD系统入口飞灰质量粒径呈典型的双峰分布，峰值分别在1和3 mm处，颗粒多呈规则球形，PM2.5与PM10质量比为0.434，飞灰总浓度约为85 mg/m3标准状态；出口处飞灰质量粒径分布也呈现双峰性，其中细颗粒比例增大，PM2.5与PM10质量比为0.764，细颗粒间相互聚集粘连形成不规则的块状结构，飞灰总浓度在23 mg/m3以下，总飞灰的脱除效率为74.5%，分级脱除效率随粒径减小而明显下降。
