摘　　要：我国工业锅炉每年耗用原煤约占年总产量的1/3,常见的燃煤工业锅炉是循环流化床锅炉。本文通过锅炉燃烧计算,对比分析煤种改变后对循环流化床锅炉运行造成的影响,提出了针对常用煤种变化后旧机组宜重新进行用煤针对性设计同时进行低氮燃烧改造,从而达到经济环保高效运行的目的。Raw coal consumed by industrial boilers in China accounts for about 1/3 of the total annual output and the common coalfired industrial boilers are circulating fluidized bed boilers.Based on the boiler combustion calculation,this paper compares and analyzes the impact of coal type changes on the operation of circulating fluidized bed boilers.It is suggested old unit should be redesigned for coal consumption after the change of commonly used coal type,and the low nitrogen combustion transformation should be carried out at the same time,so as to achieve the purpose of economical,environmentally friendly and highly efficient operation.
