一种值得关注的低阶煤高效预干燥工艺

摘要

The drying of low rank coal is the necessary pre-treatment process for its efficient utiliza-tion.A process of "fluidized-bed drying with internal waste heat utilization"which has been operated in commercial scale in Germany is expounded in this paper .The process with innovative concept of technology has advanteges of safety ,high efficiency ,low consumption and less emission .It is the ad-vanced process suitable for pre-drying of low rank coal and worth notice .%低阶煤的干燥是实现其高效利用所必须的预处理工艺。本文介绍了一种已在德国实现商业运行的“带有内部废热利用的流化床干燥”工艺。其工艺技术概念新颖，具有安全、高效、低耗、低排放的优点，是一种适用于低阶煤预干燥的先进工艺，值得关注。
