In this paper, two alternative thermo-chemical processes for waste treatment were analysed: high temperature gasification and gasification associated to plasma process. The two processes were analysed from the thermodynamic point of view, trying to reconstruct two simplified models, using appropriate simulation tools and some support data from existing/planned plants, able to predict the energy recovery performances by process application. In order to carry out a comparative analysis, the same waste stream input was considered as input to the two models and the generated results were compared. The performances were compared with those that can be obtained from conventional combustion with energy recovery process by means of steam turbine cycle. Results are reported in terms of energy recovery performance indicators as overall energy efficiency, specific energy production per unit of mass of entering waste, primary energy source savings, specific carbon dioxide production.
在本文中，分析了两种用于废物处理的替代热化学工艺：高温气化和等离子体工艺联合气化。从热力学角度分析了这两种工艺，试图利用适当的模拟工具和一些来自现有/计划中的工厂的支持数据，重建两个简化模型，以预测过程应用的能量回收性能。为了进行比较分析，将相同的废物流输入视为两种模型的输入，并对生成的结果进行了比较。通过蒸汽轮机循环对性能与常规燃烧和能量回收过程的性能进行了比较。结果以整体能源效率、单位质量进入废物的比能量产量、一次能源节约、比二氧化碳产量等能量回收性能指标来表示。
