空气重介流化床干法选煤是选煤工艺的一次改革，其工艺关键在干流化床床高及密度的均匀和稳定。本文简要介绍了空气重介流化床干法选煤的工作原理和控制机理、介绍了流化床床高和密度的在线测控方法。
Air Dense Medium Fluidized Bed Dry-process coal preparation is a reform of coal preparation process. The key of the process is the uniformity and stability of bed height and density of the fluidized bed. This paper briefly introduces the working principle and control mechanism of dry coal preparation using air Dense Medium Fluidized Bed (CFD), and introduces the on-line measurement and control method of bed height and density.
