Under the condition of organic chlorine content 0.25-0.53% of the input refuse and the furnace temperature range of 939-1,033℃, rise with furnace temperature, the proportion of lead transferred into gaseous is increased, and the lead content of fly ash and reaction ash increases obviously. It can be expressed as y1 =11.051x－9824.9 and y2 =26.729x－23680, where x is the furnace temperature, y1 and y2 are the content of lead in fly ash and reaction ash.

基於进料综合垃圾有机氯含量0.250.53％之条件下，在9391，033℃之炉温范围内，随著炉温升高，重金属铅由固相转移至气相的比例增加，飞灰及反应生成灰之铅全含量皆有明显上升之趋势，可以回归式表示为y1 = 11.051x – 9824.9以及y2 = 26.729x – 23680，其中x为炉温，y1、y2则分别为飞灰及反应生成灰之铅全含量。
