Abstract
L'invention concerne un procédé de transformation d'un matériau de départ en un produit final. Ce procédé consiste à faire réagir le matériau de départ avec un gaz dans un four à une température élevée puis à refroidir le produit final à l'aide un dispositif de refroidissement. Avant d'introduire le gaz dans le four, on augmente la température du gaz à l'aide d'un moyen d'échange thermique que l'on implante entre le four et le dispositif de refroidissement et qui facilite le transfert de l'énergie thermique, associée au produit final, au gaz.
