Description
Summary:As the emission of condensable particulate matter (CPM) could exacerbate haze pollution, recently it has received more attention. In this study, CPM and its organic components were tested at different sampling sites of a flue gas purification system under the Coal 1 and Coal 2 combustion conditions, respectively. The top 10 organic components in CPM were analyzed. The results show that under the Coal 1 and Coal 2 combustion conditions, the mass emissions of CPM at the stack inlet are 4.2 and 5.6 mg/m3, respectively, and the removal efficiency of CPM by pollution control facilities after ultra-low emission transformation are 97.21% and 98.18%, respectively. In particular, the removal rates of the organic CPM by the low-low temperature electrostatic precipitator (LLTESP), the sea water wet flue-gas desulfurization (SWFGD) and the wet electrostatic precipitator (WESP) are 71.82%, 56.36% and 76.61% by average, respectively. Among them, LLTSEP exhibits general removal effect on esters, hydrocarbon and all other organic compounds. In comparison, SWFGD excels in the removal of the hydrocarbon compounds, while WESP has remarkable performance on reducing ester compounds.
