通过对锅炉过热器、再热器分配集箱沿程静压分布和支流流量分布的分析，提出了幂函数速度分布表达式和相应的求解方法，线性速度分布只是幂速度分布在动量和摩阻影响相平衡时的特例。对动量占优势或摩阻占优势的流动状态，线性速度分布明显偏离实际，幂速度分布计算结果比线性分布结果更符合实验值。
By analyzing the static pressure distribution and the tributary flow distribution along the header of the superheater and reheater distribution of boilers, the power function speed distribution expression and the corresponding solution method are proposed. The linear speed distribution is only the distribution of the power speed in momentum and friction Special cases that affect phase equilibrium. For flow regimes with dominant momentum or frictional predominance, the linear velocity distribution deviates significantly from the actual one. The calculation of power velocity distribution is more in line with the experimental results than the linear one.
