Abstract

ES DESCRITO UN SISTEMA DE COMBUSTION DE LECHO FLUIDIZADO Y PROCESO, EN EL CUAL LA ESTEQUIOMETRIA DE CARGA TOTAL ES MANTENIDA A CARGAS INFERIORES. EL SISTEMA Y PROCESO INCLUYEN UN ENCIERRO (10) Y UNA PARTICION (20) DISPUESTA EN EL ENCIERRO PARA DEFINIR UNA SECCION DE HORNO (36) Y UNA SECCION DE AIRE SECUNDARIO PLENO (38). UN LECHO DE MATERIAL PARTICULADO COMBUSTIBLE ES FORMADO EN LA SECCION DE HORNO (36) Y EL AIRE ES PASADO DENTRO DEL LECHO EN CANTIDADES SUFICIENTES PARA FLUIDIZAR EL MATERIAL E INSUFICIENTE PARA COMBUSTIONAR COMPLETAMENTE EL MATERIAL. EL AIRE SECUNDARIO ES PASADO DENTRO DEL PLENO DE AIRE SECUNDARIO, A TRAVES DE LOS REGISTROS DE CONTROL (34) EN LA PARTICION Y DENTRO DE LA SECCION DE HORNO EN CANTIDADES SUFICIENTES PARA COMBUSTIONAR COMPLETAMENTE EL MATERIAL.
