| 摘 要： | 采用热力学平衡分析的方法对比研究了水泥窑煅烧条件下重金属Pb的迁移特性，并与焚烧炉焚烧条件下Pb的迁移特性进行了对比.采用CHEMKIN计算软件根据系统吉布斯白南能最小的原理进行计算.结果表明，Cl和SiO2都对重金属Pb的热力学行为有重要影响，Cl促进Pb的挥发，而SiO2有利于Pb的固定.在焚烧炉内，在温度高于90...

| Abstract: | An equilibrium analysis was performed to determine the migration characteristics of lead under the condi-tions of sintering in cement kiln and municipal solid waste(MSW)incineration.Using the thermodynamic equilibrium software CHEMKIN,the Gibbs free energy of the reaction system was minimized according to chemical potentials combined with atom population constraints.The results indicate that both chloride and SiO2 have great effect on the thermodynamic behavior of lead.Chlorides promote the evaporation of l... |
