Abstract

L'invention est relative à un procédé et un appareil pour récupération de chaleur à partir d'un laitier en fusion, caractérisé en ce qu'il comprend les opérations suivantes : on pulvérise le laitier en fusion s'écoulant du sommet d'une cuve à alitier en fusion d'un four métallurgique, à l'aide d'un jet d'air dirigé dans un échangeur de chaleur primaire du type cylindrique rotatif; on fait passer les granules du laitier ainsi pulvérisé à travers l'échangeur de chaleur primaire dans un courant d'air de même sens pour effectuer l'échange de chaleur avec l'air et obtenir un courant d'air chaud primaire; on introduit les granules de laitier chauds, provenant de l'échangeur de chaleur primaire, dans et à travers un échangeur de chaleur secondaire relié à l'échangeur de chaleur primaire à contre-courant par rapport à l'air froid amené de 1extérieur pour réaliser ainsi un échange de chaleur à rendement élevé, afin d'obtenir un courani d'air chaud secondaire.
