摘　　要：为分析燃烧兰炭对磨煤机出力的影响,同时提高磨煤机出力,对某电厂锅炉采用的ZGM113K型中速磨煤机性能提升进行可行性研究。试验结果表明:相比于改造前,改造后的磨煤机给料质量流量提升约35%,在保证煤粉细度的情况下,可满足锅炉燃烧的要求。To analyze the influence of the using of semi coke on the output performance of the mill, and improve the output performance of the mill, a feasibility research was conducted on the performance improvement of a ZGM113K medium-speed mill in a power plant boiler. Test results show that, compared with the data before retrofitting, the output coal mass flow rate of the mill is increased by about 35% after retrofitting. The retrofit can satisfy the requirements of the boiler combustion with the qualified pulverized coal fineness.
