Abstract
Procedimiento para el tratamiento térmico de material finamente granulado, en especial harina bruta de cemento, que se precalienta en un precalentador de ciclón de varias etapas con los gases de escape calientes de un horno tubular rotativo, que se calienta adicionalmente con combustible sólido adicional, en especial calcinándolo, y que se termina de calcinar en el horno tubular rotativo, caracterizado por el hecho de que la etapa del precalentador en la que se introduce el combustible adicional se elige, en función de la granulación, de la reactividad, de la humedad y del contenido del combustible en componentes no combustibles, de tal modo, que la mayor parte del combustible se queme de forma casi completa en la etapa extrema inferior, es decir la última en el sentido de desplazamiento de material, del precalentador.
