在很多电力企业经营过程中,影响制粉单耗的因素很多,这些因素直接影响经营成本,如煤质的影响;球磨机钢球装载量;运行调整;设备自身的问题等等。磨煤机钢球装载量直接影响磨煤机出力和电能消耗。煤质对制粉单耗的影响很大。运行参数的调整:通风量的大小决定煤粉细度,热风的开度对制粉单耗也有很大的影响,再循环的开度也会影响到制粉单耗,均匀给煤对提高制粉单耗百利而无一害,磨煤机进出口差压的影响。从设备自身的问题分析,如磨煤机套瓦的磨损,制粉系统的漏风量。
In many power companies operating process, many factors affect the milling consumption, these factors directly affect the operating costs, such as the impact of coal quality; ball mill ball loading; operating adjustments; equipment itself, and so on. Mill ball load directly affect the mill output and power consumption. Coal quality has a great impact on the consumption of milling. Operating parameters of the adjustment: the size of the air flow determines the fineness of coal, hot air opening on the milling unit consumption also has a great impact, recycling opening will also affect the milling unit consumption, uniform coal to improve the system Pollutant consumption per unit without harm, the import and export of coal mill differential pressure. From the analysis of the equipment itself, such as mill bush wear, milling system, the amount of air leakage.
