Dioxin-/Furan-“Verbrennungsprofile” in Abgasen aus Hochtemperaturprozessen

Different mechanisms downstream from high temperature processes lead to the formation of polychlorinated dibenzo(p) dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). Independent from any concentrations, these mechanisms cause comparable PCDD/F patterns, the percentage proportion of single congeners or homologous groups related to the total of 17 2,3,7,8-Cl-substituted congeners or with respect to the sum of the homologous groups tetra to octa CDD/F. The characteristics of these so-called “combustion profiles” can help to interpret corresponding data from burning and melting facilities, such as municipal waste incinerators, coal power plants, sintering plants, metal finishing facilities, cement kilns, crematoria, hazardous waste incinerators and landfill gas burners
