摘　　要：针对某电厂轴向粗粉分离器存在的缺点,对原粗粉分离器结构和参数进行了优化改造。对改造前、后的粗粉分离器性能进行了现场试验和分析。结果表明:改造后的动态分离器提高了分离效率和煤粉均匀性,改善了锅炉燃烧状况。Aiming at shortcomings of the axial coarse powder separator of a power plant, an optimization retrofit has been performed to the structure and parameters of the original coarse powder separator, while field tests and analysis carried out on the performance of the coarse powder separator before and after retrofit. Result show that the separation efficiency and pulverized coal uniformity of the dynamic separator as well as the boiler combustion are all improved after the retrofit.
