Abstract
Procedimiento e instalación para la regulación del nivel de carbono en una mezcla de gas que reacciona dentro del recinto de un horno, de tratamiento térmico, y la que dentro de la cámara del horno se produce después de la introducción de un combustible con contenido en hidrocarburos y cuyos productos de reacción no se encuentran en el equilibrio de gas de agua ni en el equilibrio de gas metano, teniendo esta mezcla de gas un excedente de metano, caracterizado porque la magnitud de regulación resulta determinada por el componente del gas de óxido de carbono CO como la primera magnitud de medición existente en la atmósfera del horno; por la tensión eléctrica de un electrólito de cuerpo sólido, que es conductor de los iones del oxígeno, como la segunda magnitud de medición; así como por la temperatura en el horno, la cual es la tercera magnitud de medición.
