Outline of Final Research Achievements

We proposed a plasma-assisted combustion as substitution of conventional catalytic combustion to reduce pollutants in the exhaust gas of combustion with fossil fuels. The purpose of this research was to verify the feasibility of the proposed method. Dielectric barrier discharge was applied to a preheated lean methane-air mixture. The results showed that the proposed method has a possibility to be used for combustion with low emission. Observation of the discharge under different temperatures in the range of 25 C to 900 C was also performed to examine behavior of the discharge under high temperatures.
