摘　　要：从燃烧活性和清洁性方面综合评价了6种生活垃圾典型可燃组分热解炭的燃烧性能。松木、纸张和橘皮等生物质类热解炭含较丰富的K/Ca等碱金属和碱土金属,碳结构规则程度相对较低,因此燃烧活性及稳定性更优。PVC、轮胎和织物等化石燃料类热解炭产率、孔隙结构、碳结构的差异较大,其中轮胎炭孔隙结构以中孔为主,且含有较多的S和Zn。生物质类热解炭焚烧烟气中NO_(x)含量相对较高(140.7~385.5 mg/m^(3)),轮胎炭焚烧烟气中的SO_(2)(1889.8 mg/m^(3))和焚烧灰渣中重金属Zn(198167 mg/kg)浓度较高,在实际应用中应给予关注。The pyrolysis char was produced from typical combustible components in MSW, and combustion behavior of which was evaluated based on both combustion activity and cleanliness. Biomass chars, prepared from raw materials such as pine wood, hardboard and orange peel chars, have relatively richer K/Ca content and less ordered carbon structure, leading to higher combustion activity and stability. The yields, texture structure and carbon structure of fossil fuel chars, such as PVC, tyre and chemical fiber fabrics chars, varied. Among which, the tyre char has a mesoporous structure and higher content of S and Zn. The NO;concentration in the flue gas from biomass char combustion was relatively higher(140.7~385.5 mg/m^(3)), while SO_(2)concentration(1889.8 mg/m^(3)) in the flue gas, and Zn content(198167 mg/kg) in the ash from tyre char combustion were relatively higher. Special attention should be paid on these pollutants in real practice.
