%X An experimental set-up was built, on which a bench-scale experimental was conducted to study the effects of SO_2 on the speciation distribution of mercury in simulated flue gases. The test method used here for mercury speciation was Ontario Hydro Method. The conclusions are as follows: In the CO_2-O_2-N_2-SO_2 system, conversion ratio of Hg~(2 ) to total Hg became lower at higher reaction temperature, SO_2 could increase the conversion ratio of Hg~(2 ) to total Hg and higher concentration of O_2 could enhance oxidation of Hg. In the CO_2-O_2-N_2-SO_2-HCl system, conversion ratio of Hg~(2 ) to total Hg became higher at higher reaction temperature, but decreased at higher SO_2 concentration. The conversion ratio of Hg~(2 ) to total Hg increased at higher HCl concentration and higher concentration of O_2 could enhance oxidation of Hg.
