| 摘 要： | 引用实验和数值的方法对柱状坩埚内含煤铬铁矿粉在微波加热场中的温度分布作了分析。对于柱状物料,不同时间内的温度的高温区域的分布是不同的,物料中水份的含量对于温度分布有着很大的影响。利用模型计算所得的温度值与实验值有很好的吻合。

| Abstract: | Temperature distribution of coal-containing chromite fines in cyclindrical crucible is analyzed by experimental and numerical methods during microwave heating. The temperature distribution changed with the Lambert's law and density of power of coal-containing chromite fines. For cylinder-shaped fines, the high temperature region exitsts different at different time. The additon of moisture content has a serious effect on the temperature distribution. The calculated temperatures are in good agreement with the experiment values. |
