In the combustion facilities, halogens (Cl, F, Br, I) should be considered with regard to the control of the compounds such as polychlorinated dibenzodioxins (PCDD), polychlorinated dibenzofurans (PCDF), halogenated polyaromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB) and volatile heavy metals formed as a result of incomplete combustion and caused adverse environmental effects. In this study halogens were observed in Izmit Hazardous and Clinical Waste Incinerator (IZAYDAS). Halogen contents of the combustion menu, flue gas, fly ash, bottom ash and filter cake were measured and their distributions in these exit streams were determined. Results showed that the major part of the halogens was partitioned to solid residues, i.e., bottom ash and filter cake which represents the removal by wet scrubbers. Fly ash and flue gas fractions of halogens were much lower due to the reduced formation of volatile compounds.
在燃烧设施中,对于多氯二苯并二恶英(PCDD)、多氯二苯并呋喃(PCDF)、卤代多环芳烃(PAH)、多氯联苯(PCB)等因不完全燃烧形成并造成不利环境影响的化合物的控制,应考虑卤素(氯、氟、溴、碘)。在本研究中,对伊兹密特危险及临床废物焚烧炉(IZAYDAS)中的卤素进行了观测。测定了燃烧物料、烟道气、飞灰、底灰和滤饼中的卤素含量,并确定了它们在这些排放流中的分布情况。结果表明,卤素的主要部分被分配到固体残渣中,即底灰和滤饼,这代表了湿式洗涤器的去除效果。由于挥发性化合物的生成减少,卤素在飞灰和烟道气中的比例要低得多。
