Suppression of soot formation in ethene laminar diffusion flames by chemical additives
- Pennsylvania State Univ., University Park, PA (United States). Dept. of Mechanical Engineering
The effects of methane, methanol, ethanol, 1-propanol, 2-propanol, carbon dioxide, and carbon disulfide addition on soot formation in ethene laminar diffusion flames were, examined. In this study, one-dimensional (1D) laser-induced incandescence (LII) and fluorescence measurements were used to determine soot volume fraction and relative soot precursor concentration, respectively, in the ethene and (ethene + additive) flames. Up to 60% reductions in soot volume fraction were found with the addition of 25% methanol to an ethene diffusion flame. More significant soot reductions were observed with the addition of carbon disulfide. It has been shown that a more than 50% reduction in soot volume fraction was achieved by adding 9.5% CS{sub 2}. Experimental results strongly suggest suppression of soot formation by methanol and carbon disulfide to be mainly a chemical effect.
