Abstract

Esta invencion proporciona un aparato y método de calentamiento nuevos para precalentar una mezcla de chatarra férrica antes de introducir la chatarra enun horno metalurgico, utilizando fundamentalmente calor recuperado de gases de deshechoemitidos por la lumbrera de escape del horno y de manera simultánea,reducir contaminantes de la chatarra y de los gases de deshecho, con el flujo concurrente hacia abajo de los gases de desecho y de la chatarra descendente.El aparato posee unacámara que i ncluye un compartimiento superior con una entrada para la chatarra en frío con el fin de depositar chatarra en fríodentro del compartimiento superior y una entrada de gas de deshechoen caliente en comunicacion de flujo con lalumbrera de escape del horno. La cámara tienetambién compartimiento inferior con un mecanismo de descarga de chatarra calentada para la descarga forzada de la chatarra calentada dentro del horno yuna salida de gas de desecho en comunicacionde flujo con un esca pe de vacío para evacuar el gas de desecho gastado. Entre cada compartimiento de la cámarahay compuertas permeables al gas que funcionan en secuencia entre posicion de compuerta cerrada y una posicion de compuesta abierta,para en concurrencia,r ecibir una carga de chatarra alimentada por gravedad desde la entrada de chatarra en frío en una posicion de compuerta cerrada, y, sostener durante unperíodo de residencia predeterminado la carga de chatarra mientras queel gas de deshecho ca liente fluye hacia abajo desde la entrada de gas caliente en elcompartimiento superior, penetra por carga de chatarra a través de las compuertas cerradas y fluye hacia fuera por la salida del gas de deshecho enelcompartimiento inferior. Las compuertas mezclan la chatarra a medida que va cayendo y sirven para regular el descenso gravitacional de la carga de chatarra
