华北电力大学本科毕业设计 PAGE PAGE IV 城市生活垃圾焚烧发电技术综合分析 摘要 目前城市生活垃圾正明显地泛滥于全世界，如何采取有效的措施来处理这些垃圾变得愈来愈重要。我国的垃圾产量惊人，但垃圾焚烧发电产业尚处于起步阶段。鉴于其对节约资源，改善环境的重要意义，给予垃圾焚烧发电技术综合分析是十分必要的。 垃圾焚烧发电不但可以减少因填埋而产生的污染，而且可以代替一部分化石燃料发电，具有双重的减排效果。科学的垃圾焚烧处理方式具有占地少、减量化、无害化等优点。本文在阅读大量国内外相关文献资料的基础上，详细论述了垃圾焚烧发电技术的原理、设备、流程，以及国内外的发展情况，对其做了较全面的初步可行性研究，并提出如何拓展具有“中国特色”的垃圾焚烧发电产业。在此基础上,对垃圾焚烧发电厂热力系统和烟气净化系统的优化设计提出了原则性建议。同时，本文还提出一种通过整合资源、政府给予政策支持的方式使关键设备、技术国产化，从而降低电价的思路。期望这篇文章能为垃圾焚烧发电项目的建设起到一定参考作用。 关键词：城市生活垃圾；垃圾焚烧发电；无害化处理；二噁英  The overall analysis of electricity’s generation from municipal solid wastes incineration Abstract It is obvious that municipal solid wastes (MSW) are overrun all over the world. How to handle these wastes in effective measures is becoming more and more important. The increase of garbage is surprising in our country. However the domestic industry of waste disposal is underway. On account of significance of waste disposal, such as economizing energy, improving environment, it is necessary to give the overall analysis of electricity’s generation from municipal solid wastes incineration. This way not only reduces the pollution in filing up the garbage but also can replace a part of the fossil fuels, which has a double effect on reducing carbon emissions. Scientific trash-burning treatment has the advantages of less land occupied, decrement and innocuity. In this paper, a lot of reading at home and abroad in the literature based on the information. Detail discusses the principle, equipment, process of the gas engineering and gas to generate electricity. It makes a general study on the initial feasibility for electricity’s generation from municipal solid wastes incineration, and puts forward the idea that how to expend the waste disposal industry in ‘Chinese characteristics’ way. On this basis, some principle recommendations have been put forward for optimizing design of the thermodynamic system and flue gas purification system for MSW incineration power plant. Meanwhile, this paper also proposes
