摘要：
Calculation model of chemical thermal dynamical equilibrium is used to predict the chemical speciation of mercury in coal fired flue gas. The results of prediction are correspondent to the experimental results from some foreign researchers, and some possible reactions of mercury in flue gas are proposed into gases in form of elemental mercury, and the existence of chlorine in flue gas greatly enhances the evaporation of mercury. As the flue gas being cooled, elemental mercury reacts with other species in flue gas. Finally most of the mercury emits into atmosphere in the form of mercury chloride.
