Effect of Hydrogen Addition on Soot Formation and Emission in Acetylene Laminar Diffusion Flame.

ABSTRACT: Hydrogen (H₂) has been regarded as a highly competitive alternative fuel that does not produce CO₂ and soot during combustion. There are few studies of cofiring H₂ with hydrocarbons. Meanwhile, the effect of hydrogen addition on soot formation and emission is questionable. In this study, the effect of H₂ addition with varying ratios (between 0 and 50% by molar fraction while the remainder is nitrogen) on soot formation in acetylene (50% by molar fraction) laminar diffusion flames was experimentally and numerically investigated. Results show that with H₂ addition, the flame height increases and the temperature decreases. The total soot emission and the primary particle size both increase with H₂ addition. The addition of H
