Abstract

To quantify TSP, PM10 and PM2.5 emission characteristics, these parameters were sampled during all processes in a coal-fired power plant. Concentrations of TSP, PM10 and PM2.5 emitted from boiler were high, and the ratios of PM10/TSP and PM2.5 /TSP were very low; this result means that the boiler emitted more coarse particles than fine particles. The ESP removed most of the coarse particles. At the FGD inlet the concentrations of TSP, PM10 and PM2.5 were low, but the ratios of PM10/TSP and PM2.5/TSP were higher than at the SCR inlet. The ESP removed ~99.8%, of the particulates but only ~99.5% of fine particles (PM10) and ~97.3% of ultrafine particles (PM2.5). Among the TSPs emitted from the stack, the proportion of PM10 was 80-85% and of this, the proportion of PM2.5 was 47-56%. Therefore, this study demonstrates that the stack of the plant emitted mostly PM10 and PM2.5, and that the ESP as the dust remover installed in the plant should be improved to remove the fine particles
