| 英文摘要 | optimizing the operating parameters to minimize polychlorodibenzo-p-dioxins and polychlorodibenzofurans (pcdd/f) emission is the common interest of the municipal solid waste (msw) incineration industry. in this study, we investigated the distribution of tetra- to octa-cdd/f along the flue gas line in a full-scale reciprocating grate incinerator and evaluated the effects of temperature control and o-2 level on pcdd/f formation. six runs were laid out and all performed under sufficient burning conditions, in which the combustion efficiency of msw was more than 99.9%. the total concentration of tetra- to octa-cdd/f measured at the boiler outlet showed an increasing tendency with the increase of boiler outlet temperature (tb) from 214 degrees c to 264 degrees c. when flue gas ran across the semi-dry scrubber and cyclone precipitator, in which the temperature varied from 264 degrees c to 162 degrees c, the concentrations of the lower chlorinated dioxins and furans were significantly raised, especially for the tcdf. increasing 02 supply from 6.0% to 10.5% essentially led to a higher yield of tetra- to octa-pcdd/f, suggested that under sufficient burning conditions the lower o-2 level was favorable for reducing pcdd/f formation and emission. the variation of o-2 level did not give rise to a systematical change of pcdd/f homologue pattern. for all measurements, the isomer distributions of tetra- to hepta-pcdd/f were more or less the same, nearly independent of variations in the operating conditions and sampling positions. only the significant increase of the sum of 1,3,7,8-tcdf and 1,3,7,9-tcdf was found in the zone after the boiler section.
