A Study of Factors Affecting Soot Formation in a Swirl-Stabilized Combustor.
Abstract
The effects of a variety of combustion and sampling variables on soot concentration and particle size distribution were studied using a swirl-stabilized laboratory combustor and an electrical aerosol analyzer (EAA). Tests were conducted over a range of reference velocities (2.5 to 10m/s) and equivalence ratios (0.05 to 0.3) for five gaseous fuels: propane, n-butane, ethylene, propylene, and 1-butene. Soot concentration and size were found to decrease with increases in either gas reference velocity or equivalence ratio. Alkenes produced more and larger soot particles tha alkanes of corresponding carbon number. Sooting tendency increased with increased carbon chain length. Probe placement and sample line length affected soot concentration measurements. Smoke number readings were obtained for comparison with EAA data. Recommendations were made for further work on the topics lightly surveyed in this study and for extensions which could possibly answer important questions raised here concerning soot growth/oxidation phenomena.
