Abstract
METODO DE ELIMINAR RECUBRIMIENTOS DE CHATARRA DE ALUMINIO. SE HACE PASAR UN LECHO DE LA CHATARRA METALICA POR UN TRANSPORTADOR PERMEABLE A LOS GASES A TRAVES DE UNA ZONA DE PIROLISIS, Y SE HACE PASAR UN GAS CALIENTE QUE CONTIENE OXIGENO EN DIRECCION DESCENDENTE A TRAVES DE DICHO LECHO, ESTANDO EL GAS A UNA TEMPERATURA TAL QUE ELEVA LA TEMPERATURA DE LA SUPERFICIE DEL LECHO A UN VALOR DE 500-600 C. SE AJUSTA LA TEMPERATURA, EL CAUDAL DE SUMINISTRO Y EL OXIGENO CONTENIDO EN DICHO GAS, ASI COMO LA VELOCIDAD DE DESPLAZAMIENTO, PARA ASEGURAR EL DESPLAZAMIENTO DESDE LA PARTE SUPERIOR A LA INFERIOR DEL LECHO DE UN FRENTE DE REACCION EN EL QUE EL MATERIAL ORGANICO SE PIROLIZA Y EL CARBON RESIDUAL SE QUEMA, EN UN TIEMPO QUE POSIBILITA LA PERMANENCIA DE LA CHATARRA HASTA 10 MINUTOS DESPUES DE QUE EL FRENTE DE REACCION ALZANZA LA PARTE INFERIOR DEL LECHO.
