Optimization of Large-Scale DBD Plasmas:Mechanism and Implications for Improved Ozone Generation

摘要

The present work explores the possibility to use inhomogeneous feed gas processing in a newly designed ozonegenerator. The design of this ozone generator allows for the possibility of increasing ozone formation throughtailoring of the dielectric barrier discharge (DBD) plasma. This new arrangement tolerates more pronouncedpower induction at the generator inlet which leads to several advantages over constant power plasma processingarrangements. The degree of filamentation emerges as the decisive factor enabling the possibility of plasmatailoring. Further evidence of increased efficiency and substantial savings of electrical power consumption areshown on an industrial scale with more than one hundred square meters of active DBD area. This paper presentsa model that is utilized to simulate the inhomogeneous power induction along the length of the ozone generatortube. The simulation is then combined with experimental data to introduce a new concept for large-scaleindustrial ozone generation known as the Intelligent Gap System (IGS).
