Abstract

PROCEDIMIENTO DE COMBUSTION QUE COMPORTA UNA PRIMERA ETAPA (1) DONDE EL COMBUSTIBLE ES QUEMADO EN LECHO FLUIDIFICADO CON UNA CANTIDAD DE AIRE SUBSTOQUIOMETRICO Y UNA SEGUNDA ETAPA (2) DONDE LOS GASES EMANADOS DEL LECHO FLUIDIFICADO Y LAS PEQUEÑAS PARTICULAS DE COMBUSTIBLE ARRASTRADAS POR ESTOS GASES SE QUEMAN CON EL AIRE SECUNDARIO, LA MAYOR PARTE DE LAS CENIZAS PRODUCIDAS EN LA PRIMERA ETAPA DE LA COMBUSTION SON EVACUADAS A ESTA ETAPA (EN 9). PARA MEJORAR EL RENDIMIENTO DE COMBUSTION, LAS PARTICULAS SOLIDAS SEPARADAS (EN 5 Y 6) DE LOS VAPORES QUE RESULTAN DE LA COMBUSTION EN LA SEGUNDA ETAPA (2), A EXCEPCION DE UN FLUJO DE PURGA (17) QUE PERMITE ELIMINAR LAS CENIZAS VOLANTES ARRASTRADAS POR LOS GASES, SON RECICLADAS A ESTA SEGUNDA ETAPA (EN 15) DE FORMA PARA OBTENER, EN ESTA ETAPA, UNA CIRCULACION EN CIRCUITO CERRADO DE LAS PEQUEÑAS PARTICULAS DE COMBUSTIBLE Y DE LAS CENIZAS VOLANTES CUYO FLUJO ES NETAMENTE SUPERIOR AL DE PURGA.
