Experimental research about the role of activating water-vapor in the DeSO/sub 2/ technology from flue gas with PPCP

In order to raise the DeSO/sub 2/ efficiency, an activating water-vapor system realized by positive DC corona discharge was set up in the front of the DeSO/sub 2/ reactor with PPCP (pulse corona induced plasma chemical process). In this paper, some tests were introduced, including the character of corona discharge in the activating system, the influence on DeSO/sub 2/ of various amount of water-vapor, and the role of activating water-vapor in the technology of DeSO/sub 2/ from flue gas with PPCP. The tests results demonstrated that the DeSO, efficiency can be increased about 20% (70%-84%, the electric power is 5 W/m/sup 3/) owing to the method of activating water-vapor.
