Abstract

Procedimiento para la inyección de combustibles líquidos en un horno alto en sustitución de una parte del coque utilizado como reductor, caracterizado porque se modifican las condiciones de circulación del viento a través del tubo cónico regulador de la tobera, a fin de originar, aguas arriba de la tobera, una zona de expansión y porque se introduce el combustible líquido en esta zona de expansión.
