摘要：

A bench scale test rig for studying reaction kinetics has been set up, with which the kinetic mechanism of oxidation of mercury in flue gas, from coal combustion, has been investigated by using simulated flue gas. Based on experimental data, a kinetic model of the morphological transformation of mercury in coal combustion flue gas is established. Herewith an equation of general homogeneous oxidation rate of vaporized mercury in flue gas, in presence of hydrochlorides, as well as an expression for calculating the relevant reaction constant is derived. The research work has provided useful data for the further development of technologies concerning ways of keeping the mercury content in flue gas under control.
