The thermal power industry is the largest coal consumer, and the contribution of its air pollutants to PM2.5 has become a hot topic of public concern, which is worthy of in-depth study. There are a total of 32 thermal power generation enterprises in Jilin Province, of which 19 are coal-fired power generation enterprises, accounting for 59.37%. Based on the investigation and analysis of the basic situation of coal-fired power generation enterprises in Jilin Province, five typical coal-fired power generation enterprises have been identified as the research objects. In general, the larger the particle size is, the higher the removal efficiency will be. After analysis, it is concluded that the final smoke and dust discharged into the environment are mainly dominated by fine particulate matter. The filtration efficiency of a well-operated bag filter for PM2.5 is higher than that of an electric dust collector. The electric-bag compound dust collector combines the advantages of electric dust collector and bag filter and has the best filtering effect. The particles at the outlet of desulfurization drift to small-size particles.
