摘　　要：比较系统地讨论了燃煤流化床多环芳烃的研究现状。首先介绍了多环芳烃的理化性质、起源及其取样和分析。其次对流化床煤燃烧过程中燃烧参数对多环芳烃形成和排放的影响进行了探讨。最后给出了多环芳烃减量化方法和净化措施。Advances in research on polycyclic hydrocarbons (PAHs) in coal-fired fluidized bed are reviewed with 33 references. Firstly, the physical and chemical properties and the origin of PAHs are undertaken. Secondly, the influence of the fuel, and the combustion variables are analyzed concerning PAHs formation and emission in coal-fired fluidized bed. Finally, the methods of minimization and purification for PAHs are mentioned.
