Abstract

UN METODO Y APARATO PARA EL TRATAMIENTO POR CALOR DE BARIO DE CAL QUE COMPRENDE EL SECAR LA CAL A SER INTRODUCIDA EN EL HORNO DE RECOMBUSTION (5) EN UN SECADERO NEUMATICO (3) POR MEDIO DE GASES DE ESCAPE DESCARGADOS DEL HORNO DE RECOMBUSTION DE CAL PARA REGENERAR EL CONTENIDO DE CAL DEL BARIO DE CAL. DESDE UN FILTRO DE SECADO (6), EL BARIO DE CAL ENGROSADO A UN CONTENIDO SOLIDO MAYOR DEL 75%, PREFERENTEMENTE EN UN 80%, ES INTRODUCIDA EN UNA CAMARA DE ALIMENTACION (2) A TRAVES DE LA CUAL ES CONDUCIDA UNA PARTE AJUSTABLE DEL GAS DE ESCAPE. DEPENDIENDO DEL CONTENIDO DE GAS, UN 100% O MENOS DEL BARIO DE CAL ES INTRODUCIDO CON EL GAS EN EL SECADOR (3), CAYENDO LA PARTE REMANENTE EN LA SECCION INFERIOR (14) DE LA CAMARA DE ALIMENTACION, DESDE DONDE ES DESPUES TRANSFERIDA AL HORNO DE RECOMBUSTION DE CAL (5).
