Abstract-In this paper, the effects of the applied voltage modes on the positive corona discharge morphology and NO removal characteristics from air stream are experimentally investigated. By using a dc superimposed high frequency ac power supply (10-60 kHz), a uniform streamer corona can be generated, which is also less sensitive to electrode mis-arrangements. Hermstein glow can be transferred to streamer corona if the peak-to-peak voltage is larger than 1.0 kV at the voltage change rate of 0.2 kV/ s. A significant amount of NO removal is observed under streamer corona. For the Hermstein glow, the removal is negligible. Moreover, the basic principle for designing ac/dc energized streamer corona is also presented in this paper.Index Terms-AC/DC superimposed operations, glow corona, NO removal, streamer corona.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
