Abstract
Un método para operar un horno de cuba incluye insertar una mezcla que incluye carbón de antracita y coque en una cavidad definida por el horno, y colocar una materia prima metálica dentro de la cavidad. El método incluye inyectar gas natural a una velocidad de flujo del gas natural y una primera cantidad de gas oxígeno a una primera velocidad del gas oxígeno en la cavidad, de manera simultánea a través de al menos un quemador. El método también incluye conducir una segunda cantidad de gas oxígeno a una velocidad de flujo supersónica del gas oxígeno en la cavidad a través de al menos una lanza, en donde la velocidad de flujo supersónica del gas oxígeno es mayor que la primera velocidad del gas oxígeno. El método también incluye quemar la mezcla dentro de la cavidad para producir un gas de combustión o de chimenea, fundir la materia prima metálica para producir un material metálico fundido, y verificar el gas de combustión para operar el horno de cuba. También se describe un horno de cuba.
