Abstract

Un aparato para producir alúmina anhidra a partir de alúmina trihidratada, que comprende un precalcinador de varios ciclones conectado a una cámara de reacción tubular que tiene un eje vertical provisto de una entrada de gas central en el fondo de la cámara y una salida de gas central en la parte superior de la cámara, que conduce a un separador de partículas/gas y conductos para introducir alúmina procedente del precalcinador y combustible en la cámara, y un refrigerador para la alúmina separada en el separador de partículas/gas, caracterizado porque la cámara de reacción está provista de una pared de fondo anular inclinado hacia abajo y hacia dentro, y porque los conductos para introducir alúmina precalcinada y combustible están situados en el fondo de la cámara de tal modo que a alúmina precalcinada y el combustible entran en la cámara en trayectorias que intersecan.
