Paper Abstract

FT-IR absorption measurements of gas phase species in highly sooting hydrocarbon flames are presented. These measurements were made in linear propane/air, methane/air and methane/ propane/air flames supported on a modified surface-mixing burner. In addition to the usual products of combustion (H2O, CO2, and CO), we have observed broad bands indicative of long chain aliphatic and olefinic hydrocarbons. Rotational temperatures computed from the CO spectrum, and hydrocarbon absorbances are presented as a function of distance above the burner surface. CH4, C2H4, and C2H2 have also been identified as decomposition products in propane/air flames.
