PURPOSE:To enable to prevent scattering of particles coming out of a fluidized layer, to reduce the height of a hollow column section and to raise the efficiency of heat transfer by recovering heat possessed by a fluid efficiently. CONSTITUTION:In a fluidized heat exchanger having a heat exchanger tube 7 extended in a fluidized layer 5 and a hollow column section 6, fins 10 are attached to the heat exchanger tube 7 at the portion thereof located at the hollow column section 6. These fins 10 are attached to the tube 7 such that the fin portions held in contact with the heat exchanger tube 7 are perpendicular to the axis of the tube 7, opposite end portions of the fins 10 are inclined in the same direction, and adjacent fins 10 are located in parallel with the direction of the ascending flow of a high-temperature fluid. |
