Abstract

L'invention concerne un dispositif de combustion en lit fluidisé comportant une enveloppe et un support de lit à diffuseur d'air pour supporter et fluidiser un lit de matériau en grains dans l'enveloppe. Le dispositif selon l'invention est caractérisé en ce qu'il comporte au moins un déflecteur disposé dans un plan pratiquement vertical et verticalement espacé du support de lit pour définir, sur un côté du lit, une zone calme de matériau en grains qui n'est pas fluidisée en fonctionnement, qui communique sous le déflecteur avec le reste du lit qui est fluidisé en fonctionnement, la partie supérieure du déflecteur étant située sous la surface supérieure du lit en fonctionnement de sorte que le matériau du lit fluidisé s'écoule, par dessus le déflecteur, dans la zone calme. Application à la fabrication des fours tunnel.
