| Abstract: | Six representative coal-fired power plants were selected and monitored for the PM10 and PM2.5 emission from these plants. The dust, PM10 and PM2.5 removal efficiencies and emission factors can be calculated based on the monitoring results, and the emission characteristics can be analyzed. The highest total dust removal efficiency among the 6 examined power plants through ESP (electrostatic precipitator) and FGD (flue gas desulfurization) is 99.88%, while the lowest efficiency is 99.75%, and the average efficiency is 99.82%. Before the ESP procedure, PM10/TSP is 20.93%~34.98%, and the average is 25.60%; PM2.5/TSP is 2.84%~4.14%, and the average is 3.39%. After the ESP and FGD procedure, PM10/TSP is 87.54%~95.90%, and the average is 91.57%; PM2.5/TSP is 41.22%~50.31%, and the average is 46.14%. PM2.5/PM10 increases from 10.74%~15.90% to 42.99%~55.14%, and the average is from 13.48% to 50.45%. The PM10 removal rate is 98.88%~99.62%, and the average is 99.29% after the ESP and FGD procedure, while the PM2.5 removal rate is 95.68%~98.47%, and the average is 97.41%. Comparing with the coal-fired power plants abroad, the 6 examined power plants have slightly larger dust emission factors than Canada and the United States in terms of kg·MWh-1 and kg·t-1. However, the PM10 and PM2.5 emission factors are much larger than in Canada and the US. |
