Previous results have shown that the plasma-combined with chemical process was effective for the control of NOχ flue gas emissions. However, we could not quantify the reaction byproducts such as N_2O, CO, CO_2, HNO_3 and No_3~ ~ ~ -. In the present stdy, two types of the plasma reactors, the ordinary ferroelectric packed-bed plasma reactor and the barrier type packed-bed plasma reactor, were evaluated with regard to reaction products nad NOχ removal efficiency. The ordinary ferroelectric packed-bed plasma reactor showed poor NOχ conversion and produced a large amount of reaction byproducts. On the other hand, the barrier-type packed-bed plasma reactor followed by the chemical reactor showed a superior results : nearly 100% NO χ decomposition with both less than 6ppm of N_2O and CO. The total operating cost becomes $2300/ton, which is at least 1/10 times more economical compared to the conventional NOχ control technologies.
