    摘要
  • 摘要: 在安鋼煉鐵廠1#高爐噴吹瘦煤時進行了煤粉粒度放寬的工業試驗.將小于74μm(-200目)的比例由70%放寬到30%后,磨煤能力提高了21%.采用粒度較粗的煤粉,風口前循環區變長,煤粉的置換比和噴煤比都有所提高,置換比和噴煤比提高的程度隨富氧率升高而增加,使高爐生產效益有了一定的改進.

     

    Abstract: An industrial experiment with rougher pulverized lean coal was carried out in 1# BF at Anyang Iron and Steel Group Co. The production of coal grinders increased by 21% as the mixing rate of the pulverized coal size under 74 um was reduced from 70% to 30%. With rougher pulverized coal, the raceway became longer and the PCI ratio as well as replacement ratio of coal enhanced. The two ratios increased as the oxygen was enriched. It is shown that much good economical benefit in BF has been reached by using rougher lean pulverized coal.
