CONDUIT ECHANGEUR THERMIQUE POUR CIRCUIT D'EVACUATION DE FUMEES

摘要

The conduit (1) has a peripheral tube (3) constituted of outer and inner walls (12, 13) arranged at a distance from each other. The inner and outer walls respectively form inner and outer surfaces. The walls combinely define a volume (20) in which a thermal insulation material is introduced. The walls define an annular filling opening (21) at the level of one out of a set truncated cone-shaped end edges (15) of the tube. The filling opening is provided for filling the material. The end edge of the tube optimizes filling of the material in the volume.
