摘要
燃煤电站耦合生活垃圾发电能够在低成本处理生活垃圾的同时实现碳减排,是燃煤电站重要的发展方向之一。本文详细介绍了我国生活垃圾的特性及处理现状,生活垃圾耦合发电模式,并分析了耦合发电对燃煤机组制粉及燃烧系统、运行安全性、煤耗、环保特性和碳排放的影响。结果表明:若生活垃圾重金属及Cl含量低、耦合比例小(低于10%),建议选择直接耦合发电;若生活垃圾重金属及Cl含量高、耦合比例大,建议选择间接耦合发电;并联耦合发电虽然不存在政策风险,但经济性最差;指出生活垃圾耦合发电目前存在缺乏相应的标准规范以及政策支持力度不够等问题。
Coal-fired power plants coupled with domestic waste can achieve carbon emission reduction while processing domestic waste at low cost,which is an important development direction of coal-fired power plants in the future.This paper introduces in detail the characteristics and treatment status of domestic waste in China,as well as the coupled power generation model of domestic waste.Moreover,it analyzes the influence of coupled power generation on pulverizing and combustion system,operation safety,coal consumption,environmental protection characteristics and carbon emissions of coal-fired units.The results show that,the direct coupling power generation is recommended when the contents of heavy metals and Cl are low and the coupling ratio is small(less than 10%).Indirect coupling power generation is recommended when the contents of heavy metals and Cl are high and the coupling ratio is large.Although the parallel coupled power generation does not have policy risks,its economy is the worst.It points out that the domestic waste coupled power generation currently has problems such as lack of corresponding standards and regulations and insufficient policy support.
