摘要
使用推舟还原炉进行铀氧化物颗粒氢气环境下的还原纯化,最大的难点在于如何做到推舟还原炉中各温区内气体分布的均匀性和温场的稳定性,结合使用工况对推舟还原炉热场和流场的数值模拟,分析了推舟还原炉炉管内部流场和温场分布,确保研制出的推舟还原炉不存在设计缺陷.在综合考虑推舟还原炉运行时的导热、对流、辐射等传热方式,获得了模拟状态下在推舟还原炉内部氢气还原时设备各温区的温度场、流场的分布情况,为该型设备设计及制造提供了重要的理论数据支撑.
Abstract
The biggest challenge in using a pusher reduction furnace for the reduction and purification of uranium oxide particles in a hydrogen environment is how to achieve the uniformity of gas distribution and stability of temperature field in each temperature zone of the pusher reduc-tion furnace.It combines the numerical simulation of the thermal and flow fields of the pusher reduction furnace under operating conditions and analyzes the internal flow field and temperature field distribution of the pusher reduction furnace tube,and ensures that the developed pusher reduction furnace has no design defects.By comprehensively considering the heat transfer modes such as conduction,convection,and radia-tion during the operation of the pusher reduction furnace,the temperature field and flow field distribution in various temperature zones of the e-quipment during hydrogen reduction inside the pusher reduction furnace under simulated conditions were obtained,providing important theoret-ical data support for the design and manufacturing of this type of equipment.
