摘　　要：运用有限元软件分析几何结构对SJ低温干馏炉内温度场和压力场的影响,研究出口直径和花墙数量不同时干馏炉内的燃烧特性。结果表明:出口直径增大时,炉腔顶部的高温范围逐渐扩大,炉内整体温度有上升趋势,炉内压力不断减小;花墙数量增多时,干馏炉顶部最高温度呈逐渐降低趋势,出口处压力向四周增大并扩散,壁面附近压力均逐渐增大。The finite element software was used to analyze the influence of geometric structure on the temperature and pressure field in SJ low temperature dry distillation,and the combustion characteristics in the dry distillation furnace was studied when the outlet diameter and number of flower walls are different.The results show that when the outlet diameter increases,the high temperature range at the top of the furnace cavity gradually expands,the overall temperature in the furnace has a rising trend,and the pressure in the furnace continues to decrease.When the number of flower walls increases,the maximum temperature at the top of the furnace gradually decreases,the pressure at the outlet increases and spreads around,and the pressure near the wall gradually increases.
