Abstract

Métodos para calentar un material sólido que comprende un material en gránulos. El polvo se separa del material en gránulos antes de que este sea calentado. El polvo se inyecta en el gas de escape proveniente del calentador. El polvo calentado se recupera y combina con el material en gránulos calentado.
