Visualization of the soot formation process in the volatile flame of single coal particle using 10-kHz PAHs-PLIF, LII and LIS

open access: yesNihon Kikai Gakkai ronbunshu, 2021
Soot formation process during coal combustion is one of a key phenomenon to achieve a high-performance furnace. This is because the thermal radiation of soot influences the temperature distribution and the heat transfer process in the furnaces.

Effects of dielectric-barrier-discharge plasma on soot and NOx in diffusion flame

open access: yesJournal of Thermal Science and Technology, 2022
In this study, we experimentally investigated soot and NOx in a diffusion flame on a coaxial burner. By applying a dielectric-barrier-discharge (DBD) plasma, we tried to reduce these emissions.
