煤岩分析在焦化企业的应用研究

Study on coal petrographic analysis applied in coking industry

主要从煤岩分析方法对煤种和混煤鉴定、指导配煤、预测焦炭质量、指导进厂煤合理分堆、测定焦炭光学组织等方面进行阐述。研究表明,煤岩分析镜质组反射率分布图对进厂煤质的鉴定及混煤情况的判别效果明显,可优化配煤方案,改善配煤比,稳定焦炭质量,指导合理堆放煤种。

This paper mainly elaborates the application of coal petrographic analysis in identification of coal types and evaluation of mixed coal,guidance of coal blending,prediction of coke quality,guid-ance in reasonable sub-heap of coal sent to the plant and determination of optical texture of coke. The study shows that the vitrinite reflectance distribution diagram of coal petrographic analysis has obvious effects in identification of quality of coal sent to the plant and evaluation of mixed coal,which could optimize the coal blending scheme,stabilize coke quality and guide reasonable sub-heap of coal types.
