  • Recent condensable particulate matter (CPM) removal methods were summarized.
  • The main components of CPM and the means of removal were investigated.
  • The efficiency of conventional dust remover on CPM removal was analyzed.
  • Effective means of CPM removal and future developments were discussed.


Emissions of total particulate matter (TPM) from stationary combustion sources consist of both filterable particulate matter (FPM) and condensable particulate matter (CPM). According to the study's findings, CPM emissions contributed significantly to the overall concentration of TPM. Therefore, there has been a growing focus on the physicochemical properties and control strategy of CPM. Firstly, this paper systematically reviewed the formation, composition, characteristics, and methods of removing CPM. Secondly, integrating the current removal methods, a cold electrode electrostatic precipitator (CE-ESP) based on the synergistic effect of multi-field coupled force on CPM coagulation and removal was put forward and installed. Thirdly, case studies of CE-ESP on CPM removal were conducted in a municipal solid waste incineration plant and a coal-fired power plant. The results showed that the removal efficiency of CPM could reach as high as 93%. The CE-ESP had a significant removal effect on both organic and inorganic substances in CPM.
