摘要
生物质-垃圾混合燃烧利弊突出,为对生物质掺烧进行综合评价和认识,本研究针对生物质特点及其与垃圾混燃过程中产生的环境问题进行分析,为生物质的推广利用提供了必要理论依据。生物质-垃圾混烧明显提高了垃圾入炉热值并缓解生物质露天无序堆放燃烧所造成的大气污染和交通安全威胁等,但同时也带来了结渣加剧、腐蚀增强、PM10和二噁英排放量增大等问题,因此需要通过添加抗结渣剂、减少生物质混烧比例、提高供气量和制备RDF等措施进行缓解。随着生物质-垃圾混合燃烧过程中环境问题的不断解决,生物质将在垃圾焚烧处理中发挥重要作用。
Biomass and waste co-combustion have both outstanding strengths and weaknesses. In order to provide enough knowledge for biomass application, this paper mainly focuses on the characteristics of biomass and environmental problems associated with biomass and waste co-combustion. Biomass co-combustion can not only increase the heating values of waste, but also reduce air pollution and safety issues resulted from biomass open burning. On the other hand, it also causes series of environmental problems, such as slag, corrosion and increasing emission of PM10 and dioxin, which needs be alleviated by adding anti-slag agent, decreasing biomass addition, enhancing air supply, producing RDF and so on. With the environmental problems being solved gradually, biomass will play a more and more important role in waste combustion process.
