摘要：
Particulate matter emitted from coal-fired power plants can be divided into filterable particulate matter (FPM) and condensable particulate matter (CPM). In the past, people paid little attention to CPM, but it is harmful to the environment and human body. In this paper, the detection methods of CPM were reviewed. The main methods are impingement condensation and dilution condensation. The development of on-line and small portable equipment is the development direction of CPM detection technology. The emission characteristics of CPM from coal-fired power plants were analyzed. CPM accounted for a high proportion of total particulate matter emissions from coal-fired power plants, and the proportion of CPM was further increased after ultra-low emission transformation, the composition of CPM emissions from coal-fired power plants varied greatly. According to the characteristics of CPM, the future research directions of CPM control technology are condensation, adsorption, wet electrostatic precipitation technology and so on. Finally, based on the current research status of CPM, it is suggested that the relevant departments of the state should formulate the detection standards of CPM emitted from fixed pollution sources such as coal-fired power plants, establish source emission inventory for coal-fired power plants with ultra-low emission transformation, and reasonably control the CPM emissions of newly built coal-fired power plants, those located in environmentally sensitive areas, and those with obvious colored plume. © 2021, Chemical Industry Press Co., Ltd.
