摘要：遵循电力行业标准DL/T 1520—2016, 采用PM-10撞击器 (30 L/min) 、质量法撞击器 (DGI, 70 L/min) 、静电低压撞击器 (ELPI, 10 L/min) 对燃煤电厂的PM_2.5进行现场对比测试;并对燃煤电厂PM_2.5排放特征进行总结。结果表明, 同一仪器不同时段的数据及不同仪器相同时间的数据重复性均较好。

Abstract：According to the DL/T 1520—2016, the PM-10 (Dekati PM-10 Impactor, 30 L/min) , DGI (Dekati Gravimetric Impactor, 70 L/min) and ELPI (Electrical Low Pressure Impactor, 10 L/min) were used to carry out the field contrast test for coal-fired power plants. Based on field observations and literature research, the preliminary characterization of PM_2.5 emissions in coal-fired power plant was summarized. The results show that the same instrument datum in the different periods and different instrument datum in the same time are all better repeatability and accuracy.
