- Abstract
- Major species production rates were measured in a small-scale two-layer environment (one meter diameter hood, 13 cm and 19 cm burners) using propane as a fuel. The species production rates were well correlated by the equivalence ration and were insensitive to the detailed structure of the buoyant diffusion flame. Further experiments were performed using propene, toluene, methanol, ethanol, isopropanol, and acetone. For all fuels tested the carbon monoxide production was a sigmoidal function of the equivalence ratio, with the maximum carbon monoxide produced under fule-rich conditions. While the amount of carbon monoxide produced is a function of the fuel chemical structure, under fuel-rich conditions the carbon monoxide production ranks according to: oxygenated hydrocarbons > hydrocarbons > aromatics. This ranking is reversed under fuel-lean conditions.
