PM2.5 were collected before and after dust collectors of five industrial fluidized bed boilers by PM2.5 sampler. The ELPI was used to monitored the number and mass concentrations of PM2.5 before and after the dust collectors, and the dust removal efficiencies of different dust collectors was analyzed. The efficiencies of electrostatic and bag filter dust collectors are high, and the efficiency of mechanical dust collector is low. NH4+, K+, Mg2+, Ca2+ cations, and F-, Cl-, NO3-, SO42-anions were analyzed by ion chromatography. It was found that the contents of Ca2+ and SO42-were higher in PM2.5 samples, and the contents of Ca2+ and SO42-were different among different boilers, The content of Mg2+ in cations is relatively low, the content of F- in anions is relatively low, and NO3-is not detected in many samples.
