Abstract

La presente solicitud describe ejemplos de procesos y sistemas para reducir la acumulación de anillos de minerales en hornos de calcinación. Los procesos y sistemas comprenden la inserción de gases no condensables (NCG) en una zona de precalentamiento de un horno de calcinación, antes del extremo de quemador. La zona de precalentamiento se puede caracterizar por temperaturas que varían de 1300 °F a 1750 °F. Sería deseable que el sistema comprendiera una cámara para insertar los NCG en la zona de precalentamiento en el horno de calcinación rotatorio.
