Description:
Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans, PCDDs/Fs, occur in the combustion of a wide variety of fuels, and is related to poor combustion conditions. This study looks at the importance of flame soot, including associated adsorbed and condensed aeromatics versus vapor-phase flame products in PCDD/F production. An ethylene diffusion flame in the presence of Cl2 was used. A better understanding of the dominant formation pathways to PCDD/F is the goal of the study, with the information to lead to better engineering controls that minimize the conditions and reactants that cause PCDD/F.
