摘　　要：对国内32台300 MW大型循环流化床锅炉的运行状况进行了分析,尽管循环流化床锅炉燃用的主要是低热值劣质燃料,但是通过及时总结设计、运行、检修维护方面的经验,得出300 MW循环流化床锅炉运行的经济性、安全性和可靠性已经得到了显著改善。另外,还针对脱硫、脱硝改造及其必要性、局部磨损防治、关键部件改造、运行诊断与优化、燃用特定煤种锅炉的开发、灰渣综合利用几个方面提出了建议,可为今后大型循环流化床锅炉的设计以及运行优化提供借鉴。This paper analyzes the 300 MW large circulating fluidized bed boiler operating conditions.By summarizing the circulating fluidized bed boiler design,operation,repair and maintenance experience,boiler operation of the economy,security and reliability has been significantly improved.Some suggestions related to the circulating fluidized bed boiler technology development is proposed,including desulfurization and denitration transformation,special area wear control,key component retrofitting,boiler operation and optimization,peak load regulation,ash utilization.The results can be applied to large-scale design and operation optimization circulating fluidized bed boiler.
