【Abstract】 A study is performed of the removal of NO x from flue gases by DC corona H 2O O 2 radical shower in conjunction with alkali solution (26% by weight of NaOH in water) scrubbing. The results of the study show that a steady streamer corona can be obtained by adjusting the flow rate of oxygen fed into nozzle electrodes. The vapor in the oxygen exercises an influence on the V 1 characteristics of the corona discharge. Both HNO 2 and HNO 3 are simultaneously generated in a reactor with DeNO x efficiency being higher than 60%. The overall DeNO x efficiency of the system can hit 80% after an alkali solution scrubbing.更多还原
