气—固两相流化床床高测量

The height measurement for an air-solid two-phase Fluidized Bed

介绍空气重介流化床干法选煤工艺过程和测控要求 ,论述了采用小型雷达测距仪测量流化床床高的可行性 ,给出了实验测量结果和分析。

This paper gives a brief account of the technical process and the requirements of measurement  control for dry cleaning of coal with an air dense medium fluidized bed and also disucsses the feasibility of the height measurement for such a fluidized bed by means of a miniature radar distance measurer. In addition, the paper gives out the experiental measurement result.
