摘要: 对炼焦煤进行工业分析,对其黏结指数、胶质层指数、煤岩指标及焦炭的光学组织和热性能进行研究,并与同类型煤质进行比较,利用煤岩学指标,判断煤的变质程度及混煤情况,可更好地鉴别炼焦煤质量。

关键词: 炼焦煤, 常规指标, 煤岩指标, 焦炭光学组织结构

Abstract:

This paper studies the proximate analysis,caking index,plastometer indices,coal petrography index of coking coal,optical structure and thermal performance of coke. It also compares with similar type of coal property to judge the degree of coal metamorphism and coal blending condition by using coal petrography index so as to better identify the quality of coking coal.

Key words: Coking coal, Conventional index, Coal petrography index, Optical structure of coke
