Abstract
UN SISTEMA Y METODO DE COMBUSTION EN LECHO FLUIDO EN EL QUE UNA SECCION DE RECICLADO ESTA LOCALIZADA DENTRO DEL CERRAMIENTO QUE ALOJA LA SECCION DEL HORNO DEL SISTEMA DE COMBUSTION. LOS GASES DE COMBUSTION Y LOS SOLIDOS QUE CONTIENE DEL LECHO FLUIDO EN LA SECCION DEL HORNO SON SEPARADOS Y LOS GASES DE COMBUSTION SE HACEN PASAR POR LA SECCION DE RECUPERACION DE CALOR Y LAS PARTICULAS MATERIALES SEPARADAS VAN AL RECICLADO DEL INTERCAMBIADOR DE CALOR. LA SECCION DE RECICLO INCLUYE UNA CAMARA DE BYPASS PARA PERMITIR A LOS SOLIDOS SEPARADOS PASAR DIRECTAMENTE DEL SEPARADOR A LA SECCION DEL HORNO. SE SUMINISTRA UN INTERCAMBIADOR DE CALOR EN LA SECCION DE RECICLADO PARA TRANSFERIR EL CALOR DESDE EL MATERIAL SEPARADO EN LA SECCION DE RECICLADO A UN CIRCUITO DE FLUJO DE FLUIDO PARA CONTROLAR LA TEMPERATURA DEL MATERIAL SEPARADO. EL MATERIAL SEPARADO EN LA SECCION DE RECICLADO SE VUELVE A PASAR A LA SECCION DEL HORNO.
