燃料燃烧细颗粒物生成特性研究进展

大气污染首要污染物为颗粒物,尤其粒径小于2.5μm的细颗粒物,被认为是引起我国雾霾天气的元凶,人们对细颗粒物生成、释放与控制问题更加关注。燃料燃烧排放的微细颗粒物是大气细颗粒物污染的主要来源之一。介绍了煤、生物质及有机固体废弃物3种燃料能源利用过程颗粒物的产生、释放特性,提出燃烧细颗粒物控制技术的未来发展方向。

The primary pollutant of air pollution is particulate matter,especially the fine particulate matter with particle size less than 2.5μm,which is the primary culprit of haze weather.Therefore,people are increasingly concerned about the generation,release and control of fine particulate matter.Fine particulate matter emission from fuel combustion is one of the main sources of fine particulate matter pollution in the atmosphere.The particulates generation and release characteristics of coal,biomass and organic solid waste during combustion and utilization are introduced comprehensively,and the development direction of fine particle control technology in the future is put forward.
