| 1 | 烟气中重金属浓度的在线测量显示文摘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. | 刘晶 郑楚光 陆继东 S.Abanades D.Gauthier G.Flamant | 2006 | 化工学报2006，57，9： | 8 |
| 2 | Volatilization of heavy metals during incineration of municipal solid wastes显示文摘Incineration experiments with MSW, which had been impregnated with heavy metals, were presented to obtain information on the volatilization behavior of the elements cadmium(Cd), lead(Pb), and zinc(Zn) under different conditions. Experiments were carried out in a bubbling fluid bed system connected to a customized inductively coupled plasma optical emission spectroscopy(ICP-OES) for analyzing metals in the flue gas. The results indicated that the combustion temperature, the gas atmosphere, and the chlorine content in the flue gas could affect the volatilization behavior of heavy metals. In the fluidized bed combustion, a large surface area was provided by the bed sand particles, and they may act as absorbents for the gaseous ash-forming compound. Comparer with the metals Cd and Pb, the vaporization of Zn was low. The formation of stable compounds such as ZnO·Al 2O 3 could greatly decrease the metals volatilization. The presence of chlorine would enhance the volatilization of heavy metals by increasing the formation of metal chlorides. However, when the oxygen content was high, the chlorinating reaction was kinetically hindered, which heavy metals release would be delayed. | SUNLu-shi S.Abanades J.D.Lu G.Flamant D.Gauthier | 2004 | Journal of Environmental Sciences2004，16，4： | 6 |
| 3 | 基于烟气重金属浓度在线监测的流化床蒸发动力学模型显示文摘应用改进的电感耦合等离子体发射光谱仪对烟气中重金属的相对浓度进行在线测量,以全面跟踪重金属的释放过程。在烟气重金属浓度实时监测基础上,发展动力学模型来研究重金属蒸发释放的动力学特性。应用矿物质基体氧化铝的实验结果来验证数学模型的有效性,理论模拟值与实验结果吻合较好。结果表明应用模型,将烟气重金属在线分析的实验结果作为输入参数,可用于预测重金属的蒸发率。根据重金属的蒸发率和固体颗粒中重金属浓度的关系得到其蒸发的动力学规律,对于氧化铝得到1级反应动力学规律。 | 刘晶 S.Abanades D.Gauthier G.Flamant 郑楚光 | 2008 | 中国电机工程学报2008，28，11： | 3 |
| 4 | 气固流化床传热特征区域的定量分析显示文摘基于作者在近期提出的一个新的综合考虑传导、对流和辐射热量传递模式的鼓泡流化床传热机理模型,对传热特征区域进行了定量的分析,提出了一个基于表征颗粒流化特性的Archemides数和传导与辐射相对重要性的Planck数的新的传热区域图。根据主导传热机理的变化,定义出9个特征区域,可供流化床设备的优化设计和正常操作参考。 | 陆继东 G.Flamant | 1995 | 化工学报1995，46，2： | 1 |
