A heat exchange bundle is provided to be designed as a module system and make it possible to separate or repair optional portions of the heat exchange bundle without disassembling the entire heat exchange bundle. As a heat exchange bundle which is housed at an inner side of a three phase fluidized-bed reactor formed by a shell, and which includes a means for introducing a reaction fluid, a means for introducing a cooling fluid, and a means for discharging a partially evaporated cooling fluid, the heat exchange bundle is characterized in that the heat exchange bundle comprises at least two identical stages(1,2,3,4) of modules, each of the modules comprises an assembly of identical fins distributed on the periphery of central tubes(Tc) that are common in an assembly of considered modules disposed across various stages of the bundle and modules aligned perpendicularly to the considered modules, and the central tubes have a function of supplying the cooling fluid to the fins of the modules as well as a function of collecting the partially evaporated fluid from the identical fins. |
