红柳选煤厂估算入洗原煤灰分指导配煤生产的实践陈亮(国家能源集团宁夏煤业有限责任公司洗选中心红柳选煤厂,宁夏银川753000)摘要:根据:原煤灰分=(精煤灰分×精煤产率+矸石灰分×矸石产率)÷100的算法原理,在上位机使用Python软件实时获取红柳选煤厂皮带秤的在线数据,计算出精煤产率、矸石产率,结合日常精煤、矸石的平均灰分(红柳选煤厂的精煤、矸石灰分比较稳定),估算出原煤灰分。然后根据精煤灰分和估算的原煤灰分,配煤生产灰分为14.50%~17.00%的产品(洗混煤),既提高了配煤产品灰分的合格率,又减少了生产过程人工采样检测灰分的劳动量。关键词:选煤厂;皮带秤;原煤灰分;配煤生产;Python软件中图分类号:TD941文献标识码:A文章编号:1005⁃8397(2023)04⁃0069⁃03EstimatingrawcoalashcontenttoguidecoalblendingproductioninHongliuCoalPreparationPlantCHENLiang(HongliucoalwashingplantofwashingcenterofnationalenergyNingxiaCoalIndustryCo.,Ltd,Yinchuan,NingXia753000,China)Abstract:Accordingto:rawcoalash=(cleancoalash×Cleancoalyield+ganguelimecontent×Gangueyield)÷100.TheonlinedataofbeltweigherofHongliucoalwashingplantisobtainedinrealtimebyusingPythonsoftwareontheuppercomputer,andtheyieldofcleancoalandganguearecalculated.Therawashcontentisestimatedbycombiningtheaverageashcontentofdailycleancoalandgangue(thecontentofcleancoalandganguelimeinHongliucoalwashingplantisrelativelystable).Then,accordingtotheashcontento...
