Condensable particulate matter(CPM) contributes a considerable proportion to the total particulate matter emitted by coal-fired power plants. In order to analyze the removal effect of CPM by existing flue gas cleaning devices

the CPM from the inlet and outlet of low-low temperature electrostatic precipitator(LLTESP)

the seawater flue gas desulfurization(SWFGD) and the wet electrostatic precipitator(WESP) of a coal-fired power plant which had implemented the ultra-low emission reform

were tested and studied. The results show that

at both 300 MW(high load) and 150 MW(low load)

the three devices mentioned above can remove the CPM effectively

and the total removal efficiency reached 97.2% and 97.6% respectively

with CPM emission concentration of 5.58 mg/m~3 and 5.55 mg/m~3 respectively. The inorganic CPM were removed more effectively than the organic CPM by both ESP and WESP. The overall removal of CPM by SWFGD was obvious

however

the Cl-anion and the Na+ cation from the sea water would be brought into the flue gas

forming a new part of CPM. The new formed CPM were removed by the WESP subsequently

ensuring a low emission concentration of CPM.
