Inverse Diffusion Flame

The inverse diffusion flame enables ICSE to study soot formation. In a normal diffusion flame, sampling gas-phase species and particles requires either placing a probe into the center of the flame, or collecting samples after the soot has passed through the oxidation zone. In an inverse diffusion flame oxygen is introduced into the center of the fuel flow, and the fuel and pyrolysis intermediates do not pass into the oxidation zone, providing an opportunity to gather large samples of young soot without invading the flame.
