Abstract

Non-thermal plasma produced by pulsed power discharge in atmospheric pressure gases has been studied for high-efficiency treatment of exhaust gases. In this paper, a short duration of 40 ns pulsed power has been applied to a mixture of nitrogen, oxygen, and water vapor, simulating flue gases to remove nitric oxide (NO). The effects of NO initial concentration and the pulsed repetition rate on the percentage of NO removal are reported. The results showed that all NO could be removed completely at different pulse repetition rates for different NO initial concentrations. The NOX removal ratio has a peak for a certain input energy. The removal of NO increased with increasing input energy density to NO (J/NO) at different NO initial concentrations.
