A pilot-scale PPCP (Pulse corona induced Plasma Chemical Process) system for controlling gas-phase dioxins and NO_x was installed in the incineration plant. The gas flow rate was varied up to 5000 Nm^3/h, branched out fromlhe existing duct. The PPCP reactor consisted of 18 tubes in a wire-cylinder configuration, energized by a 50 kW PPCP pulse generator. The decomposition efficiency for dioxins in TEQ base was more than 85% with 3〜6 Wh/m^3. The NO to NO_2 conversion was more than 93%. Then, 50 Nm^3/h of the flue gas was introduced to the chemical reactor using Na_2SO_3 solution, resulting in more than 90% of NO_x reduction with negligible by-products such as NC_2^- or NO_3^- ions.
