| 摘 要： | 综述了煤中有毒、有害元素经燃烧之后的存在形式与去向，元素在燃烧过程中的热解释放行为及其转化机理；强调煤中无机组分为主要存在许多有毒、爱元素在燃烧过程中会释放出来，然后再分异扩散到各种燃烧产物之中，地民人体廷民危害；指出今后研究不仅限于煤中有毒、有害元素的形成机理，更应侧重对燃烧产物中毒、有害元素的分异与去除方法作进一步的研究与试验，力求使燃煤对环境与人体健康产生的危害降低到最低程度。

| Abstract: | This paper briefly introduces the occurrence,fate and transformation mechanisms of toxic trace elements in coal during and after combustion.Many trace elements in coal are toxic.Most of them are bound with coal's minerals,few of them with organic matter components.These trace elements are released during the combustion process and then pose environmental and human health risk.It is suggested that further studies be dealt with not only their occurrence and forming conditions but also their transformation mechanisms and treatment of the combustion disposal,so that the risk of combustion of coals for the environment and human health could be reduced as far as possible. |
