摘　　要：针对我国超临界锅炉实际热效率难以达到设计要求的问题,本文以一台1900t/h超临界锅炉为例,量化分析了制粉系统冷风量变化对排烟温度及锅炉效率的影响,得到不同冷风量与煤耗的关系,提出了提高锅炉运行效率的有益建议。For the actual supercritical boiler thermal efficiency in our country, it is difficult to meet the design requirements of the problem, based on a 1900t/h supercritical boiler as an example, the quantitative analysis of the coal pulverizing system cold wind quantity changes on exhaust temperature and boiler efficiency, the influence of different amount of cold air and the relationship between the coal consumption, improve the boiler efficiency is good suggestion are put forward.

关 键 词：冷风 排烟温度 锅炉效率 经济性
