摘要
In the laboratory, NOx and SO2 were removed from simulated flue gas using a plasma generator. Under normal temperature conditions, the efficiencies of desulfurization and denitrification exhibited a linear relationship with plasma input power. Dielectric barrier discharge equipment was used in the mode in which flue gas was directed through the discharge zone (direct oxidation) or that in which ozonized air was produced and injected into the flue gas stream (indirect oxidation). The SO2 and NOx removal efficiencies of both methods were measured and compared. Based on the experimental results, the desulfurization and denitrification efficiencies achieved using the indirect plasma were better than those achieved using the direct plasma.
