摘　　要：通过对一台220 MW煤粉炉在再热器改造方案及改造前后试验结果的分析,揭示了燃料性质、燃烧器倾斜角度、烟气挡板开度等不同因素对锅炉各运行参数的影响,分析了改造结果与热力计算结果存在偏差的原因,为类似改造项目提供了参考和借鉴。The reheater transformation scheme and test results before and after the transformation for a 220 MW coal-fired boiler are analyzed. On this basis, the effects of fuel characteristics, inclination angle of burners and baffle opening etc. on boiler＇s operation parameters are revealed. There is deviation between the transformation and calculation results, and relevant eanses are analyzed, which provides reference for similar transformation projects.
