- Abstract
- An experimental study of the emissions of carbon monoxide and soot from liquid-fueled buoyant turbulent diffusion flames is described. These emissions are important because they are major contributors to fire hazards: inhalation of carbon monoxide is the main cause of fire fatalities, continuum radiation from soot increases fire growth and burning rates, and soo-laden smoke obscures fire fighting efforts. A correlation between carbon monoxide and soot in this laboratory confirmed this behavior for gas-fueled buoyant turbulent diffusion flames burning in still air. The present study extends this work to a broader range of hydrocarbons by considering liquid fuels in pool-like flame configurations. The objective of the present investigation was to see whether these trends continued for a broader class of hydrocarbons accessible as liquid fuels: aromatics (toluene and benzene), a heavy saturated hydrocarbon (n-heptane) and three alcohols (iso-propanol, ethanol and methanol). Ethanol and methanol were of interest to highlight the nonsooting CO emission mechanism because their flames did not emit soot for present test conditions.
