REDUCTION OF DIOXIN EMISSION FROM MSW INCINERATOR USING OXYGEN-ENRICHED COMBUSTION TECHNOLOGY: A FULL-SCALE EXPERIMENT OF STOKER-TYPE MSW INCINERATOR
Full-scale experiment was performed to evaluate the effect of oxygen enrichment on the formation and emission of polychlorinated debenzo-p-dioxins and furans (PCDD/Fs) from a stoker-type municipal solid waste (MSW) incinerator. Oxygen-enriched air, 23 vol.％ (dry basis) oxygen, was used for stable combustion of MSW with a lower heating value of 2500–3000 kJ/kg. Key incinerator operating parameters and composition of flue gas were measured. Oxygen-enriched combustion obviously increased the contents of O2 and NOx, significantly decreased CO content, but did not result in significant variations of the contents of SO2, CO2, HCl and H2O in flue gas. With oxygen enrichment, the formation rate of PCDD/Fs was decreased by 9.2％ according to TEQ value, and the emission factor of PCDD/Fs was decreased by 19.0％. Moreover, oxygen-enriched combustion did not give rise to a systematical change of the distribution pattern of PCDD/F congeners.
