| 摘 要： | 针对在建的四川中电福溪发电有限公司600MW机组锅炉采用的GS4366型钢球磨煤机的分离器的性能,采用气固双相数值模拟计算的方法,得到了调节挡板开度为64°及90°时分离器内部的气粉流场及38°～90°时分离器对各种粒度煤粉的分离效果。结果表明:挡板开度在38°～64°时有分离效果。建议在此范围内增加调节点,使分离器总体上能满足制粉系统煤粉细度及均匀性要求。 |

| Abstract: | Regarding the separator performance of a GS4366 coal ball mill for the 600 MW unit boiler under-construction in Sichuan CPI Fuxi Power Co., Ltd., a numerical simulation of gas-solid two-phase flow has been carried out to obtain gas-powder flow field in the separator at baffle openings of 64° and 90°, and determine separation effect for different particle sizes at a baffle opening in 38°-90°. Results show that the separation efficiency is relatively high when the baffle opening is in 38°-64°, therefore it is proposed to add adjustment points within this range to make the fineness and uniformity of coal powder in coal pulverizing system meet relevant requirements. |
| Keywords: | coal mill coarse coal powder separator gas-solid two-phase baffle opening particle size distribution numerical simulation |
