中文摘要：
引言 重金属元素在煤粉和城市固体垃圾燃烧过程中会分解释放出来，经历一系列物理化学变化，一部分挥发的重金属元素将富集在飞灰（尤其是亚微米级细小颗粒）上，随着烟气或炉渣排出，它们在大气中有很长的驻留时间，不为微生物降解，并转化为毒性很大的金属有机化合物，从而对人类健康和环境产生极大的危害．因此，掌握重金属元素在燃烧过程中的释放行为有助于全面认识重金属的行为以及有效控制其排放．重金属的释放行为受到重金属浓度、形态、基体组成、处理的温度、停留时间、气氛条件、气体流速以及其他成分（如氯、硫或硅铝化合物）存在的影响．
英文摘要：
An inductively coupled plasma atomic emission spectrometer （ICP-AES） was developed to continuously measure the heavy metals concentrations in flue gas in order to track the metal release process. The system is devoted to the thermal treatment of metal-spiked mineral matrix, coal and municipal solid wastes in fluidized bed （850℃）. This method was used to study the kinetics of heavy metals release. The optimum values of the gas flows from the 1200 W power generator were 0.1 L · min^-1 for the sample gas and 0. 2 L · min^-1 for argon. During the thermal treatment of coal and municipal solid waste, Cd and Pb were released readily, while Zn was released at a lower level than Cd and Pb. The formation of stable compounds such as ZnO · Al2O3 and CdO · Al2O3 from the reaction of heavy metals with fly ash particles could decrease heavy metals release. In all cases, the experimental setup was successfully used to monitor the heavy metal release process during coal and solid waste thermal treatment.
