HP中速磨煤机旋转分离器改造

Reform of Rotary Separator of HP Medium-speed Coal Mill

江苏国信扬州发电有限责任公司二期锅炉煤粉细度偏差较大,锅炉结渣严重、飞灰含碳偏高等情况影响机组安全经济运行,为此,对4号锅炉磨煤机进行旋转分离器改造。介绍了旋转分离器的改造方案、结构特点和改造后进行的验证试验,实际运行表明改造后可以有效解决锅炉存在的部分问题。

The large scatter of the fineness of pulverized coal, serious boiler slagging phenomenon as well as high carbon content in fly ash have seriously influenced the safety and economy of the coal-fired power plants of Guoxin Yangzhou Power Generation Co. Ltd. Reform of the rotary separator of No. 4 coal mill is thus performed. The reform scheme, structural features and the post-reform experimental validation are also introduced in this paper. The practical operation results show that several of the above mentioned questions can be solved effectively.
