PM2.5测试方法对比及其燃煤电厂的排放特征分析

摘要

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 PM2.5 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.%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PM2.5进行现场对比测试;并对燃煤电厂PM2.5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.
