使用微型熔炉在不同温度和气体气氛下熔化焚烧灰。对熔渣的元素组成分析结果证实，在熔化处理过程中容易释放出具有低沸点性质的重金属。排放量受工作温度下灰烬玻璃化行为的影响。还原条件下铅、锌的排放量大于氧化条件下的排放量。在本研究中检查的所有条件下，镉都完全蒸发。
Incineration ash was melted using a micro-scale furnace under various temperatures and gas atmospheres. As a result of the elemental composition analysis of the molten slag, it was confirmed that heavy metals with properties of low boiling points were readily emitted during melting treatment. The emission amount is influenced by vitrification behavior of the ash with operating temperature. The emission of lead and zinc under the reducing condition is larger than that under the oxidizing condition. Cadmium is completely vaporized under all conditions examined in the present study.
