摘　　要：针对不同的喷煤角度进行模拟,对速度场、温度场、煤粉和三次风迹线、NOx的形成和分布以及生料分解率的影响结果进行分析。结论是:1号分解炉具有较高的生料分解率,较低的NOx排放,是最佳的喷煤角度,不足之处在于容易出现局部高温;4号分解炉的生料分解率较低和NOx排放量较高。Different coal injection angles were simulated, the effects of velocity field, tem perature field, pulverized coal, tertiary wind path, NOx formation and distribution and decomposition rate of rawm aterial were analyzed. The conclusion is that: No.1 decomposing furnace has higher decomposition rate of raw material and lower NOx emission, which is the best coal injection angle,but it appears the problem of local high temperature easily. No.4 decomposing furnace has lower decomposition rate of raw material and higher emission of NOx.
