Abstract: [eng] [cze]
This paper focuses on de-NOX efficiency of the DC atmospheric pressure positive corona discharge enhanced by the flow of the mixture of nitrogen with traces of NO. The experimental findings indicate that the transformation of nitric oxide is controlled by the production of atomic nitrogen. For a particular energy density the NO decomposition increases with flow rate and higher NO removal is obtained for lower initial NO concentrations. Production of NO2 increases with increasing NO removal and NO removal energy cost for energy densities exceeding 2 kJ/m3 converges to about 100 eV/molecule. Providing that the removal of NO is predominantly driven by N atoms this would imply that the specific energy cost for the dissociation of N2 is approximately 200 eV/molecule. Byla studována energetická účinnost a cena odstranění NO v atmosférický DC koronovém výboji v N2-NO směsích.
