Modification of Medium Speed Coal Mill on Low Volatile Coal-fired Units
The pulverizing system of low volatile coal-fired power generation units usually adopts the positive pressure direct blowing pulverizing system of double-ended ball mill.There are many problems such as high power consumption,loud noise and poor economy in the double-ended ball mill pulverizing system.With the development of the power industry and the change of the coal market,the quality of coal used in many coal-fired power generation units has a large deviation from the designed coal.Based on engineering examples,a detailed technical and economic analysis was conducted on the transformation of the pulverization system of low volatile coal-fired units,which has important guiding significance for similar units.
