摘　　要：针对电站锅炉中的氨燃烧应用,首先介绍氨的基本物理化学性质、纯氨燃烧及氨与气/液体燃料混合燃烧的基础研究;然后针对新兴的燃煤电站锅炉掺氨燃烧技术,分别从氨-煤混合燃烧的燃烧与火焰传播特性、火焰形态及辐射特性、NO_(x)生成与排放特性等介绍当前研究进展;最后对电站锅炉氨燃烧的未来研究方向进行了分析和展望.氨-煤混燃可大幅降低电站锅炉碳排放,而对炉内温度特性无显著改变,虽然燃料氮的增加带来NO_(x)排放风险,但可以通过燃烧分级、燃烧组织等方式有效调控,因此氨-煤混燃是一种可行的减碳路径.以氨作为可再生能源的载体,实现热力、电力、动力等不同应用领域中的碳减排,并缓解或解决对有限化石能源的依赖,具有巨大的发展潜力和前景.The application of ammonia combustion in power station boilers was focused on.Firstly,the basic physiochemical properties of ammonia are introduced,and the fundamental combustion characteristics of pure ammonia and ammonia with other fuels are summarized.Most importantly,this paper comprehensively reviewed the current research progress on the coal-ammonia co-firing from different aspects,such as the combustion and flame propagation characteristics,flame morphology and radiation characteristics,formation and emission of NO_(x).Finally,the future research directions of ammonia combustion in power station boilers are analyzed and prospected.Ammonia coal mixed combustion can significantly reduce the carbon emission of utility boilers without significantly changing the temperature characteristics in the furnace.Although the increase of fuel nitrogen brings the risk of NO_(x) emission,it can be effectively regulated through combustion classification and combustion organization.Therefore,ammonia coal mixed combustion is a feasible carbon reduction path.Ammonia is used as the carrier of renewable energy to realize carbon emission reduction in different application fields such as heat,electricity and power,and alleviate or solve the dependence on limited fossil energy,which has great development potential and prospect.
