Abstract

L'invention concerne un rouleau pour grille de four comprenant :
- une ossature (2) formant une cage cylindrique ;
- une surface de support (4) de combustible, montée autour de ladite ossature et pourvue de moyens (5) de passage du gaz comburant au travers du rouleau, ladite surface de support étant formée par au moins un conduit (3) permettant le passage d'un fluide de refroidissement ;
ledit conduit (3) de passage du fluide de refroidissement comprend :
- une série d'anneaux (6) creux, coaxiaux à l'axe A, répartis sur la longueur dudit rouleau (1), comprenant chacun une entrée (7) et une sortie de fluide (8) ; et
- des pontages (9) connectant la sortie de fluide (8) d'un anneau (6) à l'entrée de fluide (7) de l'anneau suivant, afin de former un circuit de passage du fluide de refroidissement enroulé autour de ladite ossature (2).The invention relates to a roll for an oven rack comprising:
- a frame (2) forming a cylindrical cage;
a fuel support surface (4) mounted around said framework and provided with means (5) for passing the oxidant gas through the roller, said support surface being formed by at least one conduit (3) allowing the passage a cooling fluid;
said cooling fluid passage (3) comprises:
- a series of rings (6) hollow, coaxial with the axis A, distributed over the length of said roller (1), each comprising an inlet (7) and a fluid outlet (8); and
- bridges (9) connecting the fluid outlet (8) of a ring (6) to the fluid inlet (7) of the next ring, to form a cooling fluid passage circuit wrapped around said frame (2).

L'invention concerne également un four équipé d'un tel rouleau et l'utilisation d'un tel four.
