The paper presents results of experimental investigations of particle agglomeration by an industrial scale unipolar kinematic electrostatic agglomerator used for the agglomeration of PM2.5 particles with particles >5 μm in alternating electric field before their removal by a bag filter. The gas cleaning system comprising of electrostatic precipitator and electrostatic agglomerator was installed at a by-pass of an exhaust gas conveying duct downstream of a 225 MW_e power unit with coal-fired boiler. The flow rate through the system was between 3000 and 7500 Nm³/h. The number size distribution of particles was measured downstream of the agglomerator for various supply voltages of the agglomerator. The mass collection efficiency of this system determined from these measurements for PM10 particles was higher than 99.9%. It was also shown that the regeneration period of the bag filter downstream of the agglomerator can be extended at least five times in this system.

本文介绍了工业规模的单极运动静电凝聚器对颗粒凝聚的实验研究结果，该凝聚器用于在交变电场中凝聚大于 5 μm 的 PM2.5 颗粒，然后通过袋式过滤器将其去除。由静电除尘器和静电凝聚器组成的气体净化系统安装在燃煤锅炉的 225 MW _e发电机组下游的废气输送管道的旁路处。通过系统的流量在 3000 和 7500 Nm ^{3 之间}/H。对于凝聚器的各种电源电压，在凝聚器下游测量颗粒的数量尺寸分布。从这些测量 PM10 颗粒确定的该系统的质量收集效率高于 99.9%。还表明，在该系统中，团聚器下游的袋式过滤器的再生周期至少可以延长五倍。
