Abstract
To investigate effects of charged species on suppression of soot emission in a hydrocarbon flames, measurement of polycyclic aromatic hydrocarbons (PAHs) in a diffusion flame, applied with a corona discharge, was conducted, employing a laser induced fluorescence (LIF) method using the 3rd harmonic of an Nd:YAG laser as an excitation source. AC corona discharge (14 kHz) of low electrical current was applied to the flame upstream, to preclude effect a change of reaction by corona wind. Due to intensify of the discharge current, increase and decrease in LIF intensity of PAHs was verified.
