摘　　要：为探究磨煤机叶片形状对煤粉分布均匀性的影响,采用试验研究与数据分析相结合的方法,对圆形、椭圆形、菱形、三角形及不规则形状叶片的磨煤机进行了对比研究。结果显示,菱形叶片在提高煤粉分布均匀性方面表现最优,其煤粉分布均匀性达到了90%,相较于其他形状叶片具有显著优势。综合上述研究,针对菱形叶片形状的优化设计对于提高燃煤效率和减少二氧化碳排放具有重要意义。In order to explore the influence of mill blade shape on the uniformity of coal powder distribution,a comparative study of round,oval,diamond,triangle,and irregularly shaped mill blades was carried out by combining experimental research and data analysis.The results show that the rhombic blade has the best performance in improving the uniformity of pulverized coal distribution,and the uniformity of pulverized coal distribution reaches 90%,which is a significant advantage compared with other shaped blades.Combined with the above research,it is considered that the optimal design of rhomboid blade shape is of great significance in improving coal efficiency and reducing carbon emissions.
