ABSTRACT
In this study, we propose a plasma-chemical hybrid NOx removal process using nonthermal plasma for the treatment of flue gases emitted from glass melting furnaces; the process is demonstrated through a laboratory-scale model experiment conducted using a semi-dry desulfurization apparatus. The performance of the system for simultaneous removal of SO2 and NOx is investigated. As a result, NO is effectively oxidized to NO2 by injecting ozone into the spray region and the removal efficiencies of 90% and 50% were obtained for NO and NOx, respectively. In addition, the SO2 removal efficiency of 84% was achieved.
