Abstract

ABSTRACT 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, O3 was injected in directions opposite to the direction of gas flow at the center of the semi-dry reactor. Moreover, the effect of the increase 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 concentrations on denitration and desulfurization efficiencies were investigated.

半干式臭氧注入法玻璃炉烟气脱硝脱硫工艺性能改进
提出了一种臭氧喷射和半干法化学脱除NOx和SOx的组合工艺,该工艺采用非热等离子体处理玻璃熔窑烟气。为了进一步提高NOx的去除率,在半干式反应器中心向与气流方向相反的方向注入O3。此外,还考察了NO和SO2初始浓度的增加对其的影响。此外,还考察了气体流速对NO氧化、脱硝和脱硫效率的影响,以及NaOH浓度对脱硝和脱硫效率的影响。
