摘要
围绕大型动力煤选煤厂提质增效实践展开研究,主要聚焦于商品煤提质和品种煤增量两个方面。在商品煤提质方面,通过优化改造煤系统入洗瓶颈、提升入洗效果和分级分选效果,以及切换入洗低质煤等措施,实现了煤质量的显著提升。在品种煤增量方面,通过改造优化2-2煤块精煤增量、提升瓶颈设备能力和最大化生产特低灰煤等举措,有效提高了煤炭生产的效率和产量。本文总结了在提质增效实践中取得的成果和经验,为大型动力煤选煤厂的运营提供了有益的参考和借鉴。
This article focuses on the practice of improving the quality and efficiency of large-scale thermal coal preparation plants,mainly focusing on two aspects:improving the quality of commercial coal and increasing the variety of coal.In terms of improving the quality of commercial coal,significant improvements in coal quality have been achieved by optimizing and transforming the coal system′s washing bottleneck,improving the washing and grading effects,and switching to washing low-quality coal.In terms of increasing the variety of coal,measures such as transforming and optimizing the clean coal increment of 2-2 coal blocks,improving bottleneck equipment capacity,and maximizing the production of ultra-low ash coal have effectively improved the efficiency and output of coal production.This article summarizes the achievements and experiences achieved in the practice of improving quality and efficiency,providing useful reference and inspiration for the operation of large thermal coal preparation plants.
