Abstract
There was considered mercury removal issue from coal-fired plants’ flue gases. There was developed and studied integrated technique of selective plasma-chemical oxidation of mercury vapors with subsequent mercury oxide particles filtration. There was developed mechanism of selective impact on mercury vapors that scarcely affects other processes. The Absorption of ultra-violet radiation quanta by mercury atom leads to its electronic excitation and sharp increase of oxidation constant both molecular oxygen and ozone and other reactive species generated by plasma. There was developed technology of mercury oxide particles’ filtration, including stage of mercury particles aggregation owing to induced condensation of aqueous vapor produced by steam generator on charged particles, and stage of electro filtration of oxide-water clusters by electrostatic precipitator with water-cooled wall. There was demonstrated high efficiency of given technique, i.e. conversion of mercury vapors is 96 %.
