Abstract

EL PROCEDIMIENTO CONSISTE EN FORMAR EN UN DISPOSITIVO DE DOSIFICACION UNICO UNA MEZCLA NEUMATICA QUE CONSTA DE MATERIAS PULVERULENTAS Y DE GAS DE PROPULSION, EN PROPULSAR ESTA MEZCLA A TRAVES DE UN CONDUCTO PRIMARIO COMUN (18) EN UN DISTRIBUIDOR (20) EN EL QUE LA MEZCLA SE ESCINDE EN CORRIENTES SECUNDARIAS QUE SON ENVIADAS RESPECTIVAMENTE A CADA UNO DE LOS PUNTOS DE INYECCION A TRAVES DE CONDUCTOS SECUNDARIOS (221,222, ... 22N), EN DETERMINAR EL CAUDAL EN CAD UNO DE LOS CONDUCTOS SECUNDARIOS (221,222 ... 22N) POR LAS SECCIONES DE PASO DE TUBERIAS (281,282, ... 28N) Y EN INFLUENCIAR LAS CONDICIONES DE TRANSPORTE EN CADA CONDUCTO SECUNDARIO (221,222, ... 22N) ACTUANDO EN LA PRESION P3 EXISTENTE POR DELANTE DE CADA TUBERIA (281,282, ... 28N) A FIN DE MANTENER ESTA PRESION EN UN VALOR DETERMINADO. EL PROCEDIMIENTO SE REFIERE MAS PARTICULARMENTE A LA INYECCION DE CABON EN POLVO EN UN ALTO HORNO.
