Abstract

The Electrostatic Precipitator (ESP) combined with a pulsed power source can convert NO and SO₂ to NO₂ and SO₃ with increased PM2. 5 capture efficiency. Simultaneous removal of NO and SO₂ from flue gas by pulsed corona discharge was experimentally investigated. This paper focuses on the main factors influencing NO and SO₂ conversion efficiencies. The results indicated that by increasing pulse peak voltage, pulse frequency, number of electrodes, residence time and decreasing initial concentrations, the conversion efficiencies can be improved. High air humidity played an important role in SO₂ conversion efficiency. The NO and SO₂ conversion efficiencies reached 70% and 90% with initial concentrations of about 150 × 10^-6 in the experimental system.
