Özet

In this study, six typical coal-fired power plants (CFPPs) in Beijing-Tianjin-Hebei (BTH) region were selected to investigate the emission characteristic of PM2.5. A 5-stage large flow impact sampler (DGI) was applied to collect PM2.5. Five parallel samples were collected at the same sampling location and particles were divided into five parts:>2.5 μm、1–2.5 μm、0.5–1 μm、0.2–0.5 μm and 2.5 μm)>c ( c (0.2–0.5 μm)>c (0.5–1 μm)>c (1–2.5 μm). The analysis of element revealed that Si and Al were the main elements in PM2.5 before and after the desulfurization. The concentration of Ca, K, Na, Mg and As increased 56.62%, 29.24%, 98.78%, 114.27% and 195.34% in PM2.5 through the WFGD system and others decreased or remained constant.
