Abstract

Agglomerated and non-agglomerated SiO$_2$ particles are synthesized in a furnace by oxidation of TEOS vapor. These polydispersed particles are classified with DMA to extract particles. Then these particles are introduced into a thermal precipitator through the ESP(Electrostatic Precipitator) to investigate the themophoretic particle deposition using CNCs(Condensation Nuclei Counter). The efficiency of themophoretic particle deposition according to agglomerated and non-agglomerated particles in the thermal precipitator has been studied as a function of particle size and TEOS mole concentration using monodisperse particles classified by DMA. The results show that the particle deposition efficiency decreases as TEOS mole concentration increases and particle size increases. Thereffre, it is concluded that the thermophoretic deposition efficiency is dependent of the particle morphology.
