Effect of Induction Heating Aided Dielectric Barrier Discharge on the Elimination of SO2, NOX, and CO Gases

Abstract

In recent years, there has been an increasing need for energy, depending on population growth and the rapid development of industry. Consequently, in large power plants, factories, and vehicles, large quantities of toxic gases are emitted into the air as a result of the burning of fossil fuels every year. These gases have negative effects on both human health and the environment. In this study, a new method was proposed for eliminating environmentally hazardous flue gases without the need of any chemical catalyst unlike existing methods. In the proposed method, chemical decomposition of toxic gases was achieved by applying voltages at various frequencies to a specially designed cylindrical and coaxial dielectric barrier discharges (DBD) reactor, and in a controlled manner, the conversion of these gases to other products which could be useful was carried out. In the study, it was found that most of the gases could be separated by DBD plasma, while some of them had to be subjected to a strong preheating process in order to be separated. According to the results, high frequency plasma charge bombardment has been shown to be highly effective in the decomposition of toxic gas compounds when used together with induction heating method.
