Abstract

L'invention porte sur un tube d'échange thermique constitué d'un corps fritté dont la porosité est comprise entre 2 et 60 %, la couche superficielle du tube étant constitué d'un matériau composite en céramique et métal. De manière spécifique, lorsqu'un tube en alliage résistant à la chaleur est utilisé comme base et qu'une couche superficielle est formée d'un matériau composite en céramique et métal, ces structures sont privilégiées. La surface externe du tube en alliage résistant à la chaleur est recouverte sans liant d'un matériau composite en céramique et métal, le tube venant en contact avec le matériau composite au niveau au moins d'une partie de ses bords ; ou bien cette surface externe est ensuite recouverte sans liant d'un matériau tampon à dilatation thermique et d'un matériau composite en céramique et métal, le tube venant en contact avec le matériau tampon à dilatation thermique et/ou le matériau tampon venant en contact avec le matériau composite au niveau d'au moins une partie de ses bords. Le tube d'échange thermique assure une stabilité dans la récupération de chaleur sur une durée prolongée, dans un environnement corrosif à haute température tel que le gaz de combustion de déchets industriels.
