Abstract

SE PRESENTA UN SISTEMA Y UN METODO DE COMBUSTION DE LECHO FLUIDIZADO EN EL CUAL UNA SECCION DE INTERCAMBIO DE CALOR, QUE INCLUYE UN COMPARTIMENTO DE ENTRADA Y UN COMPARTIMENTO DE INTERCAMBIO DE CALOR, ESTA SITUADA DENTRO DE UN RECIPIENTE QUE ALOJA LA SECCION DEL HORNO DEL SISTEMA DE COMBUSTION. LOS GASES DE COMBUSTION Y LOS SOLIDOS ARRASTRADOS DEL LECHO FLUIDIZADO EN LA SECCION DEL HORNO SE SEPARAN, LOS GASES DE LA COMBUSTION SE HACEN PASAR A UNA SECCION DE RECUPERACION EN CALOR, Y EL MATERIAL EN PARTICULAS SEPARADO SE HACE PASAR DIRECTAMENTE AL COMPARTIMENTO DE ENTRADA. LA SECCION DEL INTERCAMBIADOR DE CALOR RECICLADO INCLUYE UNA CAMARA DE DERIVACION PARA PERMITIR QUE LOS SOLIDOS SEPARADOS PASEN DIRECTAMENTE DESDE EL COMPARTIMENTO DE ENTRADA HASTA LA SECCION DEL HORNO. LOS TUBOS DEL INTERCAMBIADOR DE CALOR ESTAN SITUADOS EN EL COMPARTIMENTO DE INTERCAMBIO DE CALOR PARA TRANSFERIR CALOR DESDE EL MATERIAL SEPARADO EN EL ULTIMO COMPARTIMENTO A UN CIRCUITO DE FLUJO DE UN FLUIDO PARA CALENTAR EL CIRCUITO DE FLUJO DE FLUIDO. EL MATERIAL SEPARADO EN EL COMPARTIMENTO DE INTERCAMBIO DE CALOR SE DEVUELVE DE NUEVO A LA SECCION DEL HORNO. EL AIRE SE INTRODUCE EN EL INTERIOR DEL COMPARTIMENTO DE ENTRADA PARA CONTROLAR EL FLUJO DEL MATERIAL SEPARADO POR EL SEPARADOR Y POR LO TANTO LA RELACION DE RECICLAJE.
