Combustion Characteristics of Premixing Burner Using Coaxial DBD Plasma Actuator
摘要
A dielectric barrier discharge plasma actuator (DBD-PA) was applied to combustion of a premixed gas to control the flame. By using a coaxial DBD-PA with premixed propane and air, combustion could be sustained even at low equivalence ratios that would otherwise cause blowout. Possible reasons for this are flow induced by the DBD-PA and the production of chemically active species. We first visualized the induced flow using incense particles. Next, in order to identify the chemically active species generated by the DBD-PA, optical emission spectroscopy was performed. The results obtained in this study allowed the overall combustion characteristics to be determined in detail.
