Chemical structure of medium-scale liquid pool fires

Abstract This work documents a series of time-averaged local gas species measurements made throughout the centerline profile of 30 cm methanol, ethanol, and acetone pool fires steadily burning in a quiescent environment. All gas species measurements were obtained using extractive sampling, then analyzed using a gas chromatograph equipped with a mass spectrometer detector (GC/MS). The volume fraction of each species was calculated via the number of moles identified by the GC/MS at each location along the fire's centerline. Soot mass fractions were also measured during the gas-sampling process. The gas species and soot mass fractions were compared at different locations for fires burning three fuels.
