화력발전소의 회처리장 내 비산먼지 저감을 위한 화학적 먼지억제제 적용 연구 = Application of Chemical Dust Suppressants for Control of Fugitive Dust in Ash pond of Thermal Power Plant

다국어 초록 (Multilingual Abstract)

The objective of this study is to evaluate efficiencies of chemical suppressants for control of fugitive dust in ash pond ofthermal power plant. In this study, MgCl2, PAM (polyacrylamide), and PVA (poly vinyl alcohol) that are generally appliedto suppression of fugitive dust generated from unpaved road, coal mining, storage piles and etc, were employed aschemical dust suppressants. The coal ash (coal combustion residuals) were sampled from the ash pond of Yeongheungpower division in Incheon, South Korea. The characterization of the sample including particle size distribution, pH, pHPZCand pore volume as well as XRF analysis were carried out. The suppressant treated-samples were investigated with thewind tunnel experiments to estimate and compare the effect of suppressants on stabilization of the surface of coal ashsamples. According to the results, the stability of suppressant-treated samples were significantly improved compared towater-treated samples. Among the three kinds of suppressants, PAM and PVA showed higher efficiencies and cost savingthan MgCl2.
