【摘要】 受高温真空加热工艺的制约,传统金属镁还原炉内的流动和温度分布极不均匀,排烟温度很高,炉子热效率低。本文模拟计算了新设计开发的蓄热式金属镁还原炉的热过程。通过对炉内流场和温度场的数值模拟,证明该新型还原炉在流场组织、温度场均匀性以及强化金属镁的还原过程等方面具有明显的优势。更多还原

【Abstract】 The flow and temperature distributing is very asymmetry in the conventional magnesium reduction furnace,and its high temperature of waste gas causes incredibly low energy efficiency.This paper simulates the thermal process of a new style magnesium reduction furnace that has been developed with the technology of High Temperature Air Combustion(HTAC).Numerical simulation of flow and temperature field for the new style furnace identifies the advantages of reasonable flow organization,homogeneous temperature profile and magnesium reduction enhancement.更多还原
