ABSTRACT:
In a method for decreasing the heat, impulse and material exchange in the direct vicinity of the walls of fluidized bed reactors, the flow resistance to the fluid (agitating medium) conducted through the fluidized bed will be increased in the vicinity of the walls to such an extent that the fluidized bed does not do much agitating in this region; moreover the components sticking out of the interior walls of the reactor serve to extend the rib-shapes from the wall projecting into the reaction space or parallel to the reactor wall while forming a slit with the latter. The components can be pre-fabricated segments and the distance of the annular components in the direction of flow of the fluid should at most be about half as great as the height of the ribs lateral thereto.
