The effects of particle size on the particle agglomeration in alternating electric field were examined by experimental study. 0.05㎛ particles which were mixed with particles of other size were not agglomerated in any case. The reduction rate of 0.3㎛ particles depends on the size of mixed particles while the mass loadings were kept the same. The maximum reduction rate occured when 0.3m particles were mixed with 3㎛ ones. Increasing the size of the mixed particles with 0.3㎛ particles, the reduction rate of 0.3㎛ particles linearly increased to the maximum reduction rate. After the maximum reduction rate, the reduction rate of 0.3㎛ particles decreased with increasing the size of mixed particles. The reduction rate of the fine particles increased within 0.5% when the total mass loading was increased about 33%.
The reduction rate of the fine particles increased linearly with applied voltage.
