摘要
云煤能源安宁分公司配合煤细度存在合格率低和细度波动大的问题,应用小焦炉试验研究了单种煤和配合煤细度与 CSR 的关系;通过调整 3#粉碎机变频器频率至 39 Hz,提高了配合煤细度合格率;对于 6 m 顶装焦炉,当配合煤细度越接近 76%时,焦炭CSR越处于较好水平.
Abstract
Anning branch of Yunnan Coal and Energy Co.,Ltd.faces problems of low quality rate and great fluctuation of blending coal fineness.Pilot oven test is conducted to study the co-relations between fineness of individual coal and blended coal and CSR.Fineness of blended coal is improved by adjusting the VFD of No.3 crusher to 39 Hz.For 6m top charging battery,the closer the blended coal fineness is to 76%,the better the CSR will be.
