Abstract
The present invention provides a method for making an external circulation fluid bed furnace which does not require a chamber for retaining heat transporting medium communicating with the down comer. According to the method of the present invention, said chamber is eliminated by properly determining the dimension of the down comer etc. According to the present invention, the ratio of the diameter of the down comer to the diameter of the riser so that the ratio (X) thereof falls in an area between two lines described as follows, in a Ws-X plane: Ws=12500X.sup.5 -12080X.sup.4 +4370X.sup.3 -600X.sup.2 +36X and Ws=5800X.sup.4 +1600X.sup.3 -580X.sup.2 +44X wherein, Ws is flow rate of solid heat transport medium in the riser at each unit area the cross section (kg/m.sup.2 sec); X is a ratio of the diameter of down comer (d) to the diameter of riser (D).
