冶金炉用填充球蓄热室传热过程的数值模拟及热工特性

NUMERICAL SIMULATION TO HEAT TRANSFER PROCESS AND THERMAL PERFORMANCE OF BALL PACKED-BED REGENERATOR USED IN METALLURGY FURNACE

建立了填充球蓄热室的传热数学模型，并以该模型讨论了填充球蓄热室结构参数和操作参数对热工指标的影响，以及台 热室设计中存在的某些问题；指出了烟气出口平均温度降低到２００℃以下的必要条件．

The mathematical model of ball packed-bed regenerator is established and applied to analyze the effects of the structural and operational parameters on the thermal indexes of ban packed bed regenerator. Some problems in design are clarified and the necessary condition for decreasing the exit temperature of flue gas to lower than 200℃ is put forward.
