摘要
详细阐述了内蒙古伊东集团宏鑫煤矿选煤厂末精煤干燥系统的组成、生产工艺、技术指标和技术特点,实际应用表明,该系统取得了良好的干燥效果,使末精煤水分由干燥前的28%降低至16.5%,发热量由干燥前的18.817 MJ/kg提高到20.908 MJ/kg,处理能力达到并超过了设计要求。
The paper detailed introduced the composition, operation process, technical index and charac- teristics of fine clean coal drying system in Yidong coal preparation plant of Yidong group in Inner Mongo- lia autonomous region. The operation result shows that the system obtained better drying effect, the mois- ture of fine clean coal decreased from 28% to 16.5% , and the calorie value increased from 18. 817MJ/kg to 20. 908MJ/kg after drying by this system, and the process capacity is reaching and more than the design requirement.
