摘要
对燃烧过程超细颗粒物形成机理及其控制技术的国内外研究现状进行了综述,介绍了国内外开展的有关超细颗粒物形成的影响因素、形态分析、元素分析和排放控制等几方面的研究成果,阐明了燃烧过程中超细颗粒物形成机理:在燃烧过程中,煤中无机物首先汽化,然后均相成核或者冷凝在已有的细颗粒物上。预测了超细颗粒物形成机理研究、采样和分析方法及其控制技术的发展趋势,提出目前我们应该开展超细颗粒物研究的重点和方向。
A survey of the status quo of the study both at home and abroad on superfine particle formation mechanism during coal combustion and its control technology has been given along with a description of the research results achieved worldwide in such aspects as relevant influencing factors,morphological analysis,elementary analysis and emission control etc.relating to the formation of superfine particles.The formation mechanism in question has been expounded as follows:the inorganic matter of coal during combustion will be first evaporated and then homogeneously nucleated or condensed on the existing fine particles.Furthermore,predicted was the development trend of the research on the formation mechanism of superfine particles,their sampling and analytical methods as well as control technologies with the main focus and orientation of superfine particle research to be pursued at the moment being proposed.
