Abstract

Una caldera de cama circulante fluidizada (CFB) que comprende una cámara de reaccion. Una cama fluidizada burbujeante (BFB) está contenida dentro de un cercado dentro de la porcion más baja de la cámara de reaccion y contiene un intercambiador de calor en-cama (IBHX) que ocupa la parte del piso de la cámara de reaccion. Por lo menos una válvula no-mecánica, que incluye una apertura entre la CFB y la BFB y medios controlados en forma independiente fluidizantes situados corriente arriba y corriente abajo de la apertura, que son utilizados para controlar la transferencia de calor al IBHX controlando la descarga de los solidos de la BFB a la CFB. La elevacion del fondo de la apertura está en, o sobre la elevacion de los medios fluidizantes. Una barrera de control de flujo puede estar situada corriente abajo de la apertura.
