摘　　要：陕北地区低变质煤资源丰富,是低温干馏的理想原料。目前,陕北地区煤低温干馏工艺的主要设备为内热式干馏炉。本文利用CFD软件Fluent,通过改变入口直径,分析干馏炉内的温度、压力等参数的分布规律。研究结果表明:随着入口直径增加,炉内温度减小,压力减小。The low metamorphic coal resource is abundant in Northern Shaanxi, and its coal quality makes it become an ideal material for low temperature dry distillation. At present, the main equipment of low temperature dry distillation process in Northern Shaanxi is internal hot dry distillation furnace. In this paper, the distribution of temperature and pressure parameters in a dry distillation furnace was analyzed through changing the inlet diameter by CFD software Fluent. The results showed that when the inlet diameter increased, the temperature and the pressure decreased in the furnace.
