中文摘要：
燃煤排放的超细颗粒物及其上富集的有害物质已对环境和人类健康造成了巨大危害．通过对烟煤在沉降炉内燃烧试验研究，综合分析了煤粉粒径、燃烧温度、氧气含量对一次颗粒物形成的影响，并探讨了烟煤的膨胀特性及其对颗粒物形成的影响；采用最新的采样方法和系统从空气动力学直径角度对多台燃煤锅炉除尘器入口、出口的飞灰颗粒进行13级分级取样，得到了除尘器前后飞灰颗粒、元素的质量粒径分布规律、元素分布富集规律及不同除尘器对不同粒径颗粒的除尘效率：揭示了有害元素在超细颗粒物上的分布规律：针对燃后区化学团聚促进作用进行了实验研究，发现团聚剂能较好促进超细颗粒物团聚，使烟尘排放减低50%．
英文摘要：
Many toxic trace elements arc emitted to the atmosphere, which poses considerable threat to human health and environment. The influence of coal granule size, furnace temperature, and oxygen concentration on the emission characteristics of inhalablc particles wcrc studied with a drop tube furnace. The effects on particle swelling properties wcrc also investigated. The inhalablc particulates wcrc collected at the inlet and outlet of ESP in two utility boilers by a Low Pressure Impactor （LPI） which discriminates 13 grades of particles sizing in the range from 0.03μm to 10.0μm. The distribution of major elements and toxic trace elements within different particle sizes wcrc discussed. Agglomeration experiments wcrc conducted to test the emission of toxic trace elements and inhalablc particles. The results show that the additive 2# has the best agglomeration efficiency which can help to cut the emission by 50%.
