| 摘 要： | 中国是全球碳质气溶胶最重要的贡献者之一,民用燃煤排放占有很大的比重.排放因子的不确定性直接影响碳气溶胶排放清单的准确性.本研究基于室内模拟燃烧实验和稀释通道采样系统,采用FA-3型9级撞击采样器采集了3种蜂窝煤(考虑明烧和闷烧)和包括烟煤与褐煤在内的4种块煤燃烧排放的九级粒径颗粒物,采用热光法分析了不同粒径颗粒物中有机碳(OC)和元素碳(EC)的含量,计算得到排放因子.结果表明:(1)对于蜂窝煤的明烧与闷烧,PM2.1中OC排放因子分别为0.07g·kg~(-1)和0.10 g·kg~(-1),EC的排放因子为0.002 g·kg~(-1)和0.001 g·kg~(-1);闷烧排放的有机碳颗粒物高于明烧;元素碳排放因子低于明烧.块煤排放PM2.1中OC与EC排放因子分别是1.4 g·kg~(-1)和0.02 g·kg~(-1),高出蜂窝煤排放一个数量级.(2)粒径分析结果表明,民用煤燃烧排放的颗粒物及其载带的碳组分集中在细颗粒物上,碳组分的质量中值粒径均小于2.5μm,总碳(OC+EC)的排放因子粒径分布表明蜂窝煤燃烧排放的碳组分富集于≤0.43μm粒径段,块煤富集于0.43~0.65μm粒径段.
