In this paper, the studies and applications of plasma technology for desulfurization and denitrification from flue gas are reviewed systematically.Firstly, the removal type of SO2 and NOx in flue gas under the action of plasma is introduced respectively, including the electron beam reactor, corona reactor and dielectric barrier reactor. Then, six influencing factors were analyzed: discharge voltage, flue gas flow rate, additive, humidity, oxygen content and temperature. And the removal mechanism was analyzed in detail. Finally, this paper presents desulfurization and desulfurization of plasma pilot engineering and commercial applications, proved that plasma technology in the flue gas has a unique advantage and promising potential.
