中国城市垃圾焚烧发电技术与应用

随着我国城市规模不断扩大和农村城市化进程加快,城市垃圾处理问题已成为我国不容忽视的问题。据不完全统计:我国历年堆存的垃圾已高达60亿t,且仍以10%的年增长率增加,这些垃圾不仅占用大量土地,而且对环境和居民健康产生恶劣影响。本文首先对三种垃圾处理方式(填埋、堆肥和焚烧)进行对比,认为垃圾焚烧发电是最有效的垃圾减量化、无害化、资源化处理方式。其次比较主要焚烧炉技术,并阐明了我国垃圾焚烧发电产业良好的政策扶持和发展现状。最后针对我国垃圾焚烧安全和效率问题,以及垃圾焚烧厂投资成本高的问题提出加强垃圾分类投放、分类处理和发展具有自主知识产权的焚烧技术与设备的建议,进一步得出垃圾焚烧发电产业发展空间广阔的结论。

Municipal Domestic Waste Incineration Technology and Application

With urban scale enlarging and rapid development of urbanization process,municipal domestic waste(MDW) treatment has become an noticeable problem.According to incomplete statistics,MDW shows sharp increase of 10% per year and 600 billion tons waste has accumulated in China,which occupies large space,contaminates the environment,and threatens health of people.In the paper,firstly,three main MDW treatment approach were compared(landfill,compost and incineration),and incineration was regarded as the most effec...
