Abstract

Summary Form only given, as follows. Experimental results on the removal of SO/sub 2/ from a synthetic flue gas using a dielectric-barrier discharge have been obtained. The dielectric-barrier discharge, also known as silent discharge or partial discharge, is intermittent, and the current exhibits a large number of spikes during that part of the voltage period when the discharge is burning. The discharge electrode configuration is coaxial. The inner electrode is either exposed metal or is covered with glass, and the outer electrode is quartz coated with a conducting surface. The removal of SO/sub 2/ has been studied for several different gas mixtures, flows and pressures. A typical measurement shows a 44% reduction in SO/sub 2/ concentration for a sample gas of 32 parts per million of SO/sub 2/ in air in a 15-kV, 60-Hz, and 0.75-mA silent discharge.<>
