| Summary: | Non-thermal plasma technology is an interesting method for removalof tar from gasified biomass. In this study, AC gliding-arc reactors with a reverse vortex flow configuration were developedfor biomass tar treatment. Successful generation of plasma discharge was obtained at high volume flowsof treated gas. Preliminary experimental results showed that the onset of electric discharge occurred at about 10 kV. A large numberof plasma discharges was evident. For our developed prototype, electric power input, total gas feed rate, and variouscarrier gases(Air, N2, N2+C10H8) were adjusted to investigate their effects on the dischargephenomena.The reverse vortex flow gliding arc discharges showed high residence timesfor potential chemical reactions inside the reactor. From preliminary tests, maximum removal efficiency of a representative tar compoundof more than 93%was found, atanenergy utilization efficiencyof about 30 g/kWh. |
