Abstract

Un dispositivo de boquilla difusora de gas, para una cámara de lecho fluidificado que tiene una placa de limitación o constricción dispuesta horizontalmente, estando dicha boquilla montada en aberturas respectivas de dicha placa de limitación, para pasar gas de fluidificación a través de las mismas, con el fin de mantener un lecho de sólidos fluidificados, finamente divididos, y destinada a impedir el retroceso de dichos sólidos cuando no están fluidificados, teniendo dicha boquilla un miembro tubular, abierto en la parte inferior y cerrado en la parte superior, y una porción de cabeza que se extiende hacia arriba desde la cara superior de dicha paca, caracterizado porque dicha cabeza de boquilla está provista de una pluralidad de zonas superpuestas verticalmente, que tienen pasos de gas dirigidos hacia afuera, y medios, dentro de dicha porción de cabeza, para disminuir hacia arriba la sección transversal efectiva de flujo del interior de dicha porción de cabeza, de manera que se iguale elflujo de gas de fluidificación a través de dichos pasos en las zonas respectivas.
