Abstract
The invention relates to a metal anchoring mesh intended to be secured to a metal wall of a chamber of a fluid catalytic cracking unit, in order to form cells (64). Said metal anchoring mesh comprises a plurality of wavy elementary parts (12, 14) connected successively together, forming cylindrical surfaces that are able to respectively define said cells, said cylindrical surfaces each having a central axis of symmetry A, the wavy elementary parts (12,14) each having protruding tongues (42′, 44′), said protruding tongues being able to extend respectively inside said cells (64). Said tongues (42′, 44′) extend along a length less than a quarter of the distance d that extends between said cylindrical surface and said central axis of symmetry A of said cylindrical surface.
