建立了固定源可凝结颗粒物(condensable particulate matter, CPM)采样-分析方法,开发了 CPM 采样配件,与 EPA Method 202方法进行比对后应用于燃煤电厂.结果表明燃煤电厂 CPM 排放均值为(21.2±3.5) mg?m -3,同步使用国标方法测得的FPM 为(20.6±10.0) mg?m -3；高效除尘器可有效降低 FPM 的排放水平,但对 CPM 无太大影响.高效除尘改造后 CPM 对TPM 的贡献将有所提高,应引起足够的重视. CPM 中冷凝液贡献了68％,滤膜为32％,有机组分较少,为1％.

The sampling-analysis method for CPM of stationary source was established and the sampling device was developed. The determination method was compared with EPA method 202 and applied in real-world test in coal-fired power plants. The result showed the average CPM emission concentration in the coal-fired power plant was (21. 2 ± 3. 5) mg?m - 3 while the FPM was (20. 6 ± 10. 0) mg?m - 3 during the same sampling period according to the method in the national standard. The high-efficiency dust removal device could efficiently reduce FPM emission but showed insignificant effect on CPM. The mass contribution of CPM to TPM would rise after high-efficiency dust removal rebuilding project, to which more attention should be paid. The condensate contributed 68% to CPM mass while the filter contributed 32% , and the organic component contributed little to CPM, accounting for only 1% .
