306 Development of SNCR method by Activated Ammonia Assisted by vacuum ultra violet

Abstract

To broaden and lower the temperature window of the selective non catalytic reduction (SNCR) of nitric oxide (NO), the use of activated ammonia as the reduction agent was examined. A xenon excimer lamp emitting a wavelength of 172 nm (i.e., vacuum ultraviolet; VUV) was employed as the excitation source for molecular ammonia The effects of reaction temperatures, oxygen concentrations, and length between an excimer lamp and a reactor on NO removal were investigated in a lab-scale plug flow reactor.
