Modeling the formation of precursors of dioxins during combustion of woody fuel volatiles

A detailed combustion mechanism consisting of 3678 gas-phase reactions between 755 species including chlorine chemistry has been developed. The influence of temperature, reaction time, equivalence ratio and chlorine concentration on monochlorobenzene and monochlorophenols formation was tested for batch and well-stirred reactors. The impact of good mixing conditions, appropriate level of oxygen, chlorine contents and temperature regime on the formation of precursors of dioxins is emphasized.
