High efficient discharge processes of large-capacity flue gas by using bidirectional pulse generator

Plasmas have been used to reduce flue gases. Research has shown that positive and negative coronas using pulsed voltages have an effect on removing SO/sub 2/, NO, and NO/sub 2/. In this paper bidirectional pulsed voltages are used to increase the efficiency of flue-gas reactors. The particle-mesh model using NGP (nearest-grid-point) and FEM (finite element method) calculate the detailed space-time variations of the electric fields for the streamer and it makes the characteristics of reactor clearer. In this simulation NO is considered a dominant gas.
