Abstract
La presente invención se refiere a un aparato para el control y transporte de material particulado desde un tubo vertical en una caldera de lecho fluidizado en circulación, que comprende: a) un conducto a presión y alta temperatura, que tiene una entrada de particulado y por lo menos una abertura de descarga lateral que se abre sobre el horno de dicha caldera de lecho fluidizado en circulación b) un dispositivo de tubo vertical que se proyecta hacia el interior de dicho conducto a través de dicha entrada particulado en una primera área de dicho conducto; dicho material particulado tiene un ángulo de reposo específico dentro de dicho conducto bajo presión; c) un dispositivo aereador en dicha primera área de dicho conducto para aerear y mover dicho material particulado depositado desde dicha primera área a una segunda área de dicho conducto más allá de dicha primera área; dicho material particulado se reemplaza con material particulado adicional depositado en dicha primera área desde dicho dispositivo de tubo vertical; y d) un dispositivo fluidizador en dicha segunda área de dicho conducto para fluidizar a dicho material particulado desplazado, a lo largo de dicho conducto en dicha segunda área hacia dicha abertura de descarga lateral; dicho material particulado desplazado tiene una altura generalmente uniforme en dicha segunda área; e) de manera de que dicho material particulado desplazado salga de dicho conducto a través de dicha abertura de descarga lateral hacia dicho horno de dicha caldera de lecho fluidizado en circulación; el régimen de dicha salida depende de la altura de dicha material particulado desplazado de di cha abertura de descarga lateral; dicho régimen de salida depende también del régimen con el que dicho material particulado se mueve desde dicha primera área de dicho conducto a dicha segunda área.
