DIOXIN CONTENTS IN FLY ASH FROM A FLUIDIZED BED CO-FIRING INCINERATOR

对某热电厂150吨/天垃圾和煤混烧焚烧炉百叶窗分离器收集的飞灰进行筛分和二噁英含量测定.灰样中＞100 μm的颗粒占到了86%以上.随粒径减小,二噁英总量浓度增大,且粒径＜37μm飞灰的二噁英浓度最高.二噁英的毒性当量I-TEQ值在100μm的左右两侧均随粒径增大而降低.大于100 μm的颗粒是构成原始飞灰样品二噁英总量和I-TEQ值的主要部分.呋喃氯代物是飞灰中主要的二噁英,PCDDs/PCDFs比值小于1.本文还分析了影响飞灰中二噁英生成的其它因素.
