Incineration of Pb, Cd, Zn and Cu-loaded model waste with single mode and mixture mode has been carried out in a lab-scale rotary kiln reactor to investigate the condensation distribution of their vapors in a cooling zone. The influences of the gaseous impurities including HCl, SO_2 and H_2O in the N_2/O_2/CO_2 atmosphere have been investigated. A thermodynamic pseudo-equilibrium model was also developed to evaluate the condensation mechanisms of the metallic vapors. Controlling the concentrations of SO_2 and steam in flue gas during solid waste incineration is vital for reducing the toxicity of the waste incineration residues.

在实验室回转窑反应器中对Pb、Cd、Zn、Cu四种负载模式的模拟垃圾进行了单一模式和混合模式的焚烧试验，研究了它们的蒸气在冷却带中的冷凝分布。研究了N_2/O_2/CO_2气氛中HCl、SO_2和H_2O等气体杂质对反应的影响。建立了一个热力学拟平衡模型，对金属蒸气的冷凝机理进行了分析。控制垃圾焚烧烟气中SO_2和水蒸气的浓度是降低垃圾焚烧残渣毒性的关键。
