摘　　要：能源危机和环境问题加速了环境友好、可再生替代能源的发展。使用热重分析方法对北方常见5种农业废弃生物质、污泥以及玉米秸秆和污泥混合燃料的燃烧特性进行了研究,并考察了混合燃料各组分间相互作用。结果表明:5种生物质燃料中玉米秸秆燃烧特性最好,污泥燃烧性能明显低于生物质;混合燃料燃烧时,分阶段展现出玉米秸秆和污泥的燃烧特性;随着混合燃料中污泥含量的增高,会出现不易燃尽、放热量低,以及组分间相互抑制作用。Due to the energy crisis and environment issues,the development of alternative energy sources that are environmentally friendly and renewable has been ever accelerated.In this paper,the combustion characteristics of five agricultural waste biomasses,sludge,corn stalk and sludge mixed fuels in northern China were studied using thermogravimetric analysis.The interactions between the components of the mixed fuels were investigated.The results showed that the combustion characteristics of corn straw were the best among the five biomass fuels,and the sludge combustion performance was significantly lower than that of biomass.When the mixed fuels were burned,the combustion characteristics of corn straw and sludge were exhibited in stages.With the increase of the sludge content in the mixed fuels,there will be non-burnout,low heat release,and mutual inhibition between components.
