Abstract

UN METODO Y UN SISTEMA DE COMBUSTION DE LECHO FLUIDIZADO EN EL QUE UN INTERCAMBIADOR DE CALOR DE RECIRCULACION ESTA SITUADO SUBYACENTE A LA SECCION DE HORNO DE INTERCAMBIADOR DE CALOR DE RECIRCULACION. SE PREVEN SUPERFICIES DE INTERCAMBIO DE CALOR EN UN COMPARTIMENTO DE INTERCAMBIADOR DE CALOR DE RECIRCULACION PARA ELIMINAR EL CALOR DE LOS SOLIDOS, Y SE PREVE UN COMPARTIMENTO DE DERIVACION A TRAVES DEL CUAL PASAN DIRECTAMENTE LOS SOLIDOS UN COMPARTIMENTO DE DERIVACION A TRAVES DEL CUAL PASAN DIRECTAMENTE LOS SOLIDOS AL HORNO DURANTE LAS CONDICIONES DE ENCENDIDO Y DE BAJA CARGA. EL FLUJO DE SOLIDOS ENTRE COMPARTIMENTOS ESTA SELECTIVAMENTE CONTROLADO Y UNA VALVULA EN L CONECTA UNO DE LOS COMPARTIMENTOS A LA SECCION DE HORNO. EL AIRE PASA DENTRO DE LA VALVULA EN L PARA PROMOVER EL FLUJO DE LOS MATERIALES SEPARADOS DEL ULTIMO COMPARTIMENTO HACIA EL HORNO. LA VELOCIDAD DE FLUJO DEL AIRE SE MODULA PARA HACER VARIAR EL FUNCIONAMIENTO DEL INTERCAMBIADOR DE CALOR DE RECIRCULACION.
