假定长柱状颗粒堆积体系为连续介质所建立的传热微分方程结合第一类齐次边界条件,得到了基于第一类Bessel函数的温度分布无穷级数表达式T(r,t),近似计算了合金罐内颗粒石灰石的传热时间及物料预热对传热时间的影响,计算结果与工业化实验结果较为接近。 Assuming that the long columnar particle accumulation system is the differential equation of heat transfer established by continuous media and the first homogeneous boundary conditions, the expression of infinite series of temperature distribution T (r, t) based on the Bessel function of the first kind is obtained. The approximate calculation The effect of heat transfer time and preheating of granular limestone in heat treatment time on the heat transfer time were calculated. The calculated results are in good agreement with the industrialized experimental results.
