PURPOSE:To improve the separation of gas and duct, by providing a horizontal fluidized bed type heat exchange apparatus for contacting coarse particles heated by a tower type solid-gas heat exchange apparatus with separate fine particles countercurrently and a transport line for recirculating coarse particles between both apparatuses. CONSTITUTION:Coase particles are contained with the gas rising from the lower part of a tower type solid-gas heat exchange apparatus 120 and fallen while receives heat exchange to be supplied to a horizontal fluidized bed type heat exchange apparatus 101 through a coarse particle discharge port 117, a chute 112 and a coarse particle supply pipe 104. A coarse particle bed 111 is formed above the dispersing plate 102 in the horizontal heat exchange apparatus 10 and moved toward an outlet side while fluidized and crosses over a weir B to be discharged to a coarse particle discharge port 107. Then, said coarse particles pass through an air screening pipe 8, a rotary valve 109 and a recirculation line 113 to be returned to the top part 119 of the tower type solid-gas heat exchange apparatus 120. |
