摘要: Lignite briquettes with different salt contents (“normal”-coal: 300 ppm w/w, “salt”-coal: 2000 w/w) were burned in a common type of house heating facility. The content polychlorodibenzodioxins and furans (PCDD/F) the flue gas bottom ash determined. values calculated from homologue sums significantly higher for “salt”-coal regarding their concentrations slightly increased respect to ashes. Taking account wide variety additional analytical parameters considering mechanistic aspects, our assumtion was proved that chlorine is responsible these values. evaluation profiles isomer distribution shows mechanism formation PCDD/F similar both coal sorts; whereas, however, compounds ashes occurs under conditions. Based on quantitative results, an assessment lignite domestic as source given.
