Influence of activated water vapor in process of DeSO2 from flue gas by pulsed discharge plasma

An activating electrode system (AES) with brushy nozzle plate structure is placed prior to pulsed discharge electrode system (PDES) to activate water vapor. The purpose is to produce more radicals in relation to H 2O to increase DeSO 2 efficiency in the process of DeSO 2 by pulsed discharge. In the paper, several aspects are investigated, including the features of corona discharge in AES, pulsed discharge waveform affected by water vapor, DeSO 2 by activated vapor in AES, effects produced by activated vapor in DeSO 2 process by pulsed discharge. The basic mechanism of DeSO 2 by activated vapor is discussed briefly. According to the experimental data, it is known that the removal rate of SO 2 is increased 10% above the original level by the method.
