城市垃圾焚烧发电项目Municipal solid waste incineration power generation project方案江苏国际经济技术合作公司20XX/2/20前言Preface随着城市化进程的加快，垃圾污染日益严重。对垃圾处理不当，会造成严重的大气、水和土壤污染，并将占用大量土地，从而制约城市的生存与发展。如何解决垃圾问题，已引起全社会的高度重视。城市垃圾是居民生活产生的废弃物，但从另一个角度来说，垃圾也不是百无一用的废物，如果科学地加以利用，它也是地球上可以不断增长的可再生资源。面对垃圾泛滥的现状，全球专家已经不再仅仅着眼于控制和销毁的被动防守，而是主动将垃圾和能源这一废一宝紧密联系起来，例如：利用垃圾发电来解决能源问题。With the acceleration of the urbanization process, the waste pollution is being more and more serious. Improper disposal of waste will cause serious air, water and soil pollution, and will occupy a lot of land, thereby restricting the survival and development of the city. How to solve the garbage problem has aroused great attention of the whole society.City residents living garbage is a waste, but from another perspective, the garbage is not good for nothing waste, if science is to use, it is also the earth could be growing renewable resources. Facing the situation of garbage flooding, global experts have not only focus to control and destroy the passive defense, but this initiative will waste energy and waste a precious together, for example: the use of garbage power to solve the energy problem.一、建设规模Construction scale一个总人口130万，中心城区人口40万，农村人口90万的城市，日产垃圾约650吨/日，利用这些生活垃圾建设垃圾焚烧发电厂，建设2台日处理垃圾400吨的焚烧炉配置2套9MW的汽轮发电机组。其主机技术条件如下：A total population of 1 million 300 thousand, the center of the urban population of 400 thousand rural population, 900 thousand of the city, Nissan garbage about 650 tons / day, the use of these waste construction waste incineration power plant, turbine generator incinerator configuration of 400 tons of construction waste disposal, 2 sets of 2 sets of 9MW.
