Abstract

NO is one of the most important pollutants during combustion. The combined electrostatic precipitator (ESP) has a character of denitrification with the increasing efficiency of catching particulate matters smaller than 2.5 μm (PM2.5). During pulse corona discharge, the formation of ozone and free radical has important effect on NO oxidation. Electron with high energy can also break N-O directly and the dissociative N can form N₂. Accordant with dust catching efficiency, line-cylinder chamber is better than line-plate chamber. With the increase of voltage, the denitrification efficiency becomes higher. Under a certain voltage, the efficiency of denitrification is strongly influenced by the initial concentration of NO and NO₂. In the reactor developed by this paper, the oxygenation efficiency can be higher than 90% when the voltage is 50kV and the initial NO volume percentage is less than 10^-4. The oxidation outcome NO₂ can be absorbed by wet gas desulphuration (WGD) technology.
