Abstract
Specific combustion programs (Gaseq, Chemical equilibria in perfect gases, Chris Morley)are used to model dioxin and formation in the incineration processes of urban solid wastes. Thanks to
these programs, it is possible to establish correlations with the formation mechanisms postulated in li-
terature on the subject. It was found that minimum oxygen quantities are required to obtain a
significant formation of these compounds and that more furans than dioxins are formed. Likewise,
dioxin and furan formation is related to the presence of carbon monoxide, and dioxin and furan
distribution among its different compounds depends on the chlorine and hydrogen relative
composition. This is due to the fact that an increased chlorine availability leads to the formation of
compounds bearing a higher chlorine concentration (penta-, hexa-, hepta-, and octachlorides), whereas
an increased hydrogen availability leads to the formation of compounds bearing a lower chlorine
number (mono, di-, tri-, and tetrachlorides)
