摘要：
The effects of the temperature, oxygen concentration, and excess oxygen coefficient on mercury oxidation under O-2/CO2 and O-2/N-2 coal combustion were experimentally analyzed in a fluidized bed. The results Suggested that both the concentration and proportion of Hg-0 increased as the temperature increased under: oxy-coal combustion. Mercury was also primarily in elemental form at high temperatures under oxy-coal combustion. Mercury oxidation was much less effective in the presence of CO2. The percentages of Hg-0 and Hg2+ increased as the excess oxygen coefficient increased under oxy-coal combustion.
