| Abstract: | The removal of SO2 from flue gas by pulsed coronadischarge in presence of ammonia was experimentally investigated.The results show that the SO2 removal mainly depend on thermalreaction of SO2 with NH3 and enhancement of 0%-25% by pulsed coronadischarge in the range of the specific energy 0-5 Wh/Nm3. Theaerosol mass concentration, mainly composed of ammonium sulfate,increases with specific energy dissipated into the reactor. With aninitial concentration of 2000-2100 ppmv SO2 and energy consumptionof 3 Wh/Nm3, when a stoichiometric amount of ammonia is injected,the removal efficiency of SO2 and percentage of ammonium sulfatesin reaction products are all ≥80%. The collection efficiency of thereactor for aerosol is about 74% at a flue gas temperature of 60 to65℃ and a water vapor content of 9% to 11% volume. |
