“…Benzene was the major aromatic species in both flames reaching maximum mole fractions of 280 ppm and 343 ppm for Flame A and Flame B, respectively. These levels are similar to the benzene levels reported by Bakali et al [20] in their 1.9 equivalence ratio n-heptane flame. As expected, increase in equivalence ratio increased the mole fractions of aromatic and PAH species.…”

The micro-structure of laminar premixed, atmospheric-pressure, fuel-rich flames of n-heptane/oxygen/argon has been studied at two equivalence ratios (C/O ϭ 0.63 and C/O ϭ 0.67). A heated quartz microprobe coupled to an online gas chromatography/mass spectrometry (HP 5890 Series II/HP 5972) has been used to establish the identities and absolute concentrations of stable major, minor, and trace species by the direct analysis of samples withdrawn from the flames. Benzene was the most abundant aromatic compound identified. The largest PAH detected were the family of C 18 H 10 (molecular weight of 226) that include cyclopenta[cd]pyrene and benzo[ghi]fluoranthene, with peak concentrations reaching 8 ppm and 6 ppm, respectively. Soot particle diameters, number densities, and volume fractions were determined using classical light scattering and extinction measurements. The largest soot particle diameter measured was about 18 nm and the soot volume fraction reached the amount of 4.9 ϫ 10 Ϫ7.

“…Except C 4 H 2 , the concentration levels of lowmolecular-weight hydrocarbon species (i.e. C 2 H 2 , C 3 H 4 , and C 4 H 4 ) in the reference flame were in agreement with those reported earlier for a premixed, fuel-rich n-heptane flame [8]. The differences in C 4 H 2 concentrations are about a factor of 10-30.…”

“…In general, the addition of oxygenate increased the maximum flame temperature and the highest temperatures were obtained for flame-B. A maximum flame temperature of about 1600 K has been reported for the premixed n-heptane flame at an equivalence ratio of 1.9, which is slightly higher than our temperature measurements because their flame was leaner [8].…”

“…Atmospheric pressure, premixed, flat flames of n-heptane were investigated using unheated microprobe sampling and GC/MS both by Bakali et al [8] and Ingemarsson et al [9] at equivalence ratios of 1.9 and 1.0, respectively. Their studies were limited to low-molecularweight species only.…”

Atmospheric pressure, laminar, premixed, fuel-rich flames of n-heptane/oxygen/argon and n-heptane/oxygenate/oxygen/argon were studied at an equivalence ratio of 1.97 to determine the effects of oxygenate concentration on species mole fractions. The oxygen weight percents in n-heptane/oxygenate mixtures were 2.7 and 3.4. Three different fuel oxygenates (i.e. MTBE, methanol, and ethanol) were tested. A heated quartz micro-probe coupled to an on-line gas chromatography/mass spectrometry has been used to establish the identities and absolute concentrations of stable major, minor, and trace species by the direct analysis of samples, withdrawn from the flames. The oxygenate addition has increased the maximum flame temperatures and reduced the mole fractions of CO, low-molecular-weight hydrocarbons, aromatics, and polycyclic aromatic hydrocarbons. The reduction in mole fractions of aromatic and polycyclic aromatic hydrocarbon species by an increase in oxygenate concentration was more significant. q
