流化床换热器的研究（Ⅰ）

The Fluidized-Bed Heat Exchanger(Ⅰ)

在流化床换热器中，固体颗粒在流化介质作用下保持流化状态，因此有着良好的传热性能，应用前景广阔。本文研究了单管流化床中几种固体颗粒的流化行为及内循环流化系统和外循环流化系统的运行情况。得到了一些有用的数据和结论，为进一步研究创造了条件，并将为其应用提供参考依据。

The fluidized-bed heat exchanger within which the solid particles are kept in a fluidized condi-tion by the fluid medium,so as to achieve a good heat transfer has a broad prospect for its applica-tion.With the single-tube fluluized-bed the foundamental fluidization behaviours of different kindSof solid particles,and the oporating conditions for both syste ms of inter-circulation and outer-circu-lation fluidized-beds were studied.The data obtained are referential for further study.
