Abstract: The invention relates to a device for reducing fouling in a tube (1) through which a fluid passes. The inventive device comprises a mobile rotary element (3) and a fixed bearing-forming element (2) which can be solidly connected to the upstream end of the tube (1). In addition, the mobile element (3), which is connected to the fixed element (2), comprises an upstream trunnion-forming part (4) and a downstream turbulence-generating part (5) which is shaped such as to be rotated by the flow of the fluid in the tube (1). The aforementioned upstream (4) and downstream (5) parts are connected to one another by means of an elongated flexible connector (6) that is deformable along the entire length thereof.

Abstract: A method wherein the particles are homogeneously distributed like rain to constitute a horizontal bed of particles on the entire section of the chamber (1). The invention is characterised in that it consists in temporarily modifying at least once the loading conditions, so that the profile of the surface (8) of the bed of particles forms, at least at the periphery thereof, an angle &agr; with the horizontal ranging between 6° and 25°, preferably, between 10° and 20°, and in subsequently restoring the loading conditions to obtain a horizontal bed.
