Emission Factor of PM2.5 from Crop Straw Burning

  • 摘要: 农作物秸秆燃烧是一类重要的生物质燃烧形式,已是大气细粒子的来源之一.建立了实验室模拟-稀释通道采样系统,并利用这一系统测定了浙江、四川、河南、河北、北京(主要粮食产区)五地的玉米、小麦和水稻秸秆燃烧过程中PM2.5的排放因子.结果表明:实验室模拟明火燃烧的w(PM2.5)为7.2~39.0 g/kg,与文献[5],[7]~[8]中野外燃烧结果相似,表明两者燃烧状态具有相似性;排放因子受秸秆燃烧状态影响显著,闷火燃烧为明火燃烧的2.4~11.5倍;同时,农作物种类不同PM2.5排放因子也存在明显差别;而排放因子随秸秆生长地域变化比较小.
