摘　　要：依据试验结果分析了燃烧器风门开度、旋流强度及配风方式对高温再热器壁温的影响。通过调整燃烧器风门、旋流强度以及改变配风方式使得高温再热器壁温分布形态得到改善,减小了温差,从而保证再热器汽温达到设计参数,为同类型锅炉运行提供参考。Based on the test results,it analyzes opening value of burner damper,swirling intensity and effect of wind distribution on wall temperature of final reheater.By adjusting the burner damper,swirling intensity,and changing the air distribution method,it improves the wall temperature distribution of final reheater,and reduces the temperature difference,so as to ensure that the reheating temperature reaches the design parameters,which has important guiding significance for the operation of the same type of boiler.
