摘要：

Critical equivalence ratios ( phi //c) have been measured as a function of temperature (1600-1880K) for premixed flames at atmospheric pressure. The five fuels studied are methane, ethane, propane, ethylene, and acetylene. The flames were stabilized on a flat flame burner and the temperatures were measured using sodium D-line reversal. A linear relationship is found between ln phi //c and 1/T for each fuel. Based on a global kinetic model in which soot precursors are formed by fuel pyrolysis and oxidized by OH, a predictive correlation has been developed which shows the influence of temperature, OH concentration, and C/H ratio on sooting tendency. This correlation describes all of the measured phi //c versus temperature data, suggesting that the overall mechanism of soot formation is similar among aliphatic fuels.
