Here we report the experimental and simulation results of removal of SO{sub 2} and NO from a simulated coal combustion gas using a dielectric-barrier discharge. A Monte Carlo calculation is done to determine the transport properties of the flue gas. Following this, a detailed plasma chemistry calculation is done which takes into account the pulsed nature of the dielectric-barrier discharge. The computed results are in good agreement with the experimental data. We find that in low concentrations (400 ppm for SO{sub 2} and 100 ppm for NO) the dielectric-barrier discharge was capable of removing 99{percent} of the SO{sub 2} and NO. Due to temperature dependence of the heavy particle reactions, there is a decrease in NO removal as the energy density is increased past an optimum value. {copyright} {ital 1996 American Institute of Physics.}
