The simulation results show that staged air can significantly reduce tangential circle diameter of upper parts of furnace and lower heat transfer difference of horizontal gas flue; the field test results show that the proper ratio of staged air in the total air can make tubes wall temperature distribution of high-temperature superheater uniform, and tubes' peak temperature lowered 5~10℃.

模拟计算结果表明炉内分级送风对于减小炉膛上部切圆直径、降低水平烟道内的热偏差作用明显；现场试验结果表明，适度增大炉内分级送风比例使高温过热器管壁温度分布更均衡，峰值温度降低5～10℃，使受热面运行安全性得以提高。

Thus, the velocity magnitude is far bigger than that of optimal design velocity magnitude, which will lead to serious wear and tear in metal face of heater.
