Experimental study is made on the feasibility of the combination of the products collection and SO 2 removal. Certain effect of products′ collection is obtained in the process of SO 2 removal by pulse corona discharge. The collection efficiency rises with increasing resident time, the peak value and pulse frequency, which is consistent with the variety of SO 2 removal efficiency according to the aforementioned parameters. Collection of SO 2 removal products is effectively obtained by adding DC bias voltage to pulse corona discharge reactor. The collection efficiency rises with increasing DC bias voltage and resident time. The collection efficiency is up to 95.1% in the devices used.
