摘要:      建立顶燃式热风炉内的三维、稳态传热和流动数学模型,求得了炉内温度场和速度场;在此基础上,探讨了不同空/煤气入口布置对炉内温度场和速度场的影响。研究结果表明:煤气入口单一布置时,炉内流体的温度场及速度场的分布均极不均匀,且偏向煤气入口侧炉壁;空/煤气入口间隔布置时,炉内流体的温度场及速度场分布均较为均匀,这种布置方式有利于热风炉的稳定运行。

Abstract: A mathematical model was established, which is a three-dimensional and steady-state heat transfer and flow process mathematical model in top combustion stove. Then the temperature field and velocity field were obtained according to the model. Based on these, the temperature and velocity fields were discussed under the conditions of various air and gas inlet position. The results show that when the gas entrance in single-channel mode, the liquid's temperature and velocity distribution was uneven extremely and tilted toward the furnace wall of gas entrance side in the hot blast stove. On the other hand, when the air and gas entrance in interval mode, the liquid's temperature and velocity distribution is uniform, and this mode is beneficial to the top combustion stove to work steadily.
