Abstract
LA INVENCION SE REFIERE AL TRATAMIENTO TERMICO DE MATERIAL GRANULADO FINO, QUE PRIMERO SE PRECALIENTA EN UN CICLON PRECALENTADOR (1) DE VARIAS ETAPAS, SEGUIDAMENTE SIGUE CALENTANDOSE EN UNA ZONA DE CALCINACION (4) PARA TERMINAR A CONTINUACION LA COCCION EN UN HORNO (2), Y FINALMENTE SE ENFRIA. UNA CAMARA DE REACCION DE LA ZONA DE CALCINACION (4) SE ALIMENTA CON MATERIAL PRECALENTADO Y AIRE TERCIARIO, PARA MANTENER EN ELLA UNA ATMOSFERA REDUCTORA A FIN DE REDUCIR EL CONTENIDO DE NO X EN LOS GASES DE COMBUSTION. PARA FACILITAR EL AJUSTE DE LA TEMPERATURA DE REACCION EN LA CAMARA (6) Y REDUCIR EL VOLUMEN DEL EQUIPO, EL MATERIAL PRECALENTADO SE TRASLADA DE LA SEGUNDA ETAPA DE PRECALENTAMIENTO (1B) MAS BAJA, JUNTO CON AIRE TERCIARIO (7A''), A LA PARTE INFERIOR DE LA CAMARA DE REACCION (6), Y UNA CANTIDAD PARCIAL AJUSTABLE DE MATERIAL PRECALENTADO DE LA TERCERA ETAPA DE PRECALENTAMIENTO (1C) MAS BAJA A UNA PARTE SUPERIOR (12B'', 12B") DE LA ZONA DE CALCINACION (4).
