摘要
分析了新鲜垃圾和陈旧垃圾的组分和热值特性,指出陈旧垃圾中的可燃组分可制成垃圾衍生燃料(RDF)作为新鲜垃圾焚烧的辅助燃料,尤其是在新鲜垃圾中的塑料加以回收后更有必要。在分析RDF的气化和燃烧特性的基础上,对RDF用于气化发电和用作新鲜垃圾焚烧炉的辅助燃料进行了经济与环境效益对比,发现RDF更适合作为鲜垃圾焚烧炉的辅助燃料。
Fresh and aged MSW were analyzed and characterized for their composition and lower heat values （LHV）. It was found that fresh MSW are characterized with high moisture content and low LHV, while combustibles in aged MSW are mainly plastics and of lower moisture content therefore can be made into RDF. There are two systems for this RDF utilization： one is used in newly sep--up gasification and generation system; another is used as auxiliary fuel in fresh MSW incinerators. The gasification and combustion characteristics were investigated, and then economic factors and environmental impacts of two systems were compared, the results suggested that it is better to use RDF as auxiliary fuel in fresh MSW incinerators to avoid fuel oil consumption.
