加压循环床中竖管传热试验研究

Experimental Research on Vertical Tube Heat Transfer in a Pressurized Circulating Fluidized Bed

作者在一床高6 m,内径80mm的冷态加压循环床试验台上采用电加热竖管进行了床内对流试验研究。研究结果得到操作参数对床内局部换热系数的影响规律.

In this paper, the experimental research of convective heat transfer between bed and a vertical tube which is electrically heated is presented. The experiment was carried out in a cold model of a pressurized circulating fluidized bed which column has a 6m height and 80 mm ID. The effects of various operating parameters on the local heat transfer coefficients are obtained.
