THE FORMATION AND BEHAVIORS OF DIOXINS AND RELATED COMPOUNDS IN DIFFERENT INCINERATION PROCESSES IN JAPAN
Introduction Recent progress in combustion and flue gas cleaning techniques has generally reduced dioxin emissions from modern incineration plants. However, the occurrence and changes in dioxins (DXNs) can be observed during gas flow from incinerators to advanced gas cleaning equipment. The authors have demonstrated such formation of DXNs around dust collection processes in different incineration plants and a relationship between DXNs and dioxin surrogate compounds. In this study, further measurements were conducted to show the difference in formation characteristics between a former-type facility including an electrostatic precipitator (EP) and a brand new gasification-melting facility. The results obtained for flue gas and precipitated fly ash may provide help with interpreting the final emission data for DXNs in the latest incineration plants. Hexachlorobenzene and surrogate organic halogens were also measured.
