循环流化床电厂燃料的三级筛分方案研究

Research on Third Grade Screening System of CFB Power Plant

循环流化床锅炉对燃煤粒度级配的要求,完全依靠燃煤筛分破碎系统,要求燃煤通过筛分破碎系统后,能够获得理想的颗粒。研究三级筛分系统可以有效控制入炉煤粒度,提高锅炉运行的稳定性和燃烧效率。

The particle size gradation required by circulating fluidized bed（CFB） boiler completely depends on the coal screening and crushing system.It is necessary for coal to achieve the ideal particles through the screening and crushing system.The research on third grade screening system will control the coal particle size effectively,which will improve the stability of boiler operation and increase the combustion efficiency.
