摘　　要：Vortexing limestone injection into furnace combined with calcium lime hydration in the downstream is the most promising technology for controlling SO 2 emission. Particle imaging velocimetry (PIV) is used to measure the gas liquid solid three phase flow field in a reactor. By image processing based on newly developed software, the number concentrations of sorbent particles and water droplets are presented. The measuring results are very helpful for better understanding the desulfurization mechanism and optimizing configurational and operational parameters in the hydration reactor. 炉内旋涡喷钙尾部增湿活化脱硫技术是控制燃煤SO2 排放最有发展前景的技术之一 .采用先进的颗粒速度图像仪 (PIV)测定了活化反应器内气液固三相流场 .利用二次开发的软件 ,经过图像处理得到活化反应器内脱硫剂颗粒和雾化水滴数量浓度 .研究结果对于深入理解活化反应器内浆滴促进脱硫机理、优化结构和运行参数具有重要意义 .
