The paper proposes a critical assessment of municipal solid waste gasification today, starting from basic aspects of the process (process types and steps, operating and performance parameters) and arriving to a comparative analysis of the reactors (fixed bed, fluidized bed, entrained bed, vertical shaft, moving grate furnace, rotary kiln, plasma reactor) as well as of the possible plant configurations (heat gasifier and power gasifier) and the environmental performances of the main commercially available gasifiers for municipal solid wastes. The analysis indicates that gasification is a technically viable option for the solid waste conversion, including residual waste from separate collection of municipal solid waste. It is able to meet existing emission limits and can have a remarkable effect on reduction of landfill disposal option.
本文对当前城市固体废物气化进行了批判性评估，从该过程的基本方面（工艺类型和步骤、操作和性能参数）开始，到对反应器（固定床、流化床、夹带床、竖炉、移动炉排炉、回转窑、等离子体反应器）以及可能的工厂配置（热气化炉和动力气化炉）和主要的商业可用城市固体废物气化炉的环境性能进行比较分析。分析表明，气化是固体废物转化的一种可行的技术选择，包括来自城市固体废物分类收集的残余废物。它能够满足现有的排放限制，并且可以显著减少垃圾填埋的处理方式。
