Performance Improvement in Semi-dry Ozone Injection NOx and SOx Removal Process for a Glass Furnace Flue Gas

A combined ozone injection and semi-dry chemical NOx and SOx removal process using nonthermal plasma for the treatment of flue gases emitted from glass melting furnaces has been proposed. To further improve the NOx removal, O-3 was injected in directions opposite to the direction of gas flow at the center of the semi-dry reactor. Moreover, the effect of the dincrease in initial concentrations of NO and SO2 was investigated. In addition, the effect of the gas flow rate on NO oxidation, denitration, and desulfurization efficiencies, and the effect of NaOH and SO32- concentrations on denitration and desulfurization efficiencies were investigated.
