Abstract: This paper described the emission situation of pollutants from coal combustion in China, and it was pointed out that the removal technology of fine particulate matter was an important goal to be solved urgently. The research progress of soot control technology for coal burning at home and abroad was reviewed, and the principle, characteristics and research progress of the smoke and dust control technology were introduced. The results show that low⁃low temperature electric dust removal technology, agglomeration technology and synergistic removal technology have become the hot spots of fine particulate emission control technology and have a good application prospect. In addition, the analysis points out the difficulties faced by each part and the development direction, and provides reference for the removal of fine particulate matter from smoke and dust to meet the requirement of ultra⁃low emission standard.
