摘要： 采用克拉玛依25＃变压器油在烟雾箱内进行直接燃烧模拟，确定燃烧产生烟尘颗粒及多环芳烃（PAHs）的排放因子。结果表明：烟尘颗粒的排放因子随燃烧量增加呈先增大后降低并趋于稳定的变化特征，稳定状态下小烟雾箱得到烟尘颗粒的排放因子大于大烟雾箱。新油和废油燃烧产生PAHs的谱分布接近，以中高环PAHs占主导，不同于变压器油中以低环PAHs为主的分布特征。中高环数PAHs排放因子随燃烧量的变化特征更接近烟尘颗粒，稳态条件下新油燃烧得到的PAHs排放因子高于废油，毒性等效当量都以BaP占绝对优势。

Abstract: By experiments of 25# Karamay transformer oil combustionin smoke box, the soot particles and PAHs emission factor(EF) were identified. The results indicated that, the EF values increases with the amount of burned oil and then decreases and remains steady with small fluctuation; The average value of EF for smoke from steady stage using large smog chamber was less than that using small chamber; The PAHs profiles from the combustion of new and wasted oil are the same, dominated by mid-to-high ring compounds, and are significantly different from those in transformer oil dominated by low ring compounds; The characteristics of the EFs for mid-to-high ring compounds varying with the amount of burned oil were more similar to those of smoke; The EF of the total PAHs for new oil combustion smoke from steady stage was higher than that for decommissioned oil, and the toxicity was dominated by benzo(a)pyrene.
