Abstract
SE PRESENTA UN HORNO PARA UN TRATAMIENTO OSCURECEDOR (1), QUE COMPRENDE UN QUEMADOR DE GENERACION DE HOLLIN (4) PARA INSUFLAR UNA LLAMA DE COMBUSTION INCOMPLETA HACIA AMBAS SUPERFICIES DE UNA BANDA DE ACERO INOXIDABLE (3) QUE PASA DE FORMA CONTINUA. UN PAR DE BOQUILLAS SECUNDARIAS DE AIRE (5) INSTALADAS EN UNA POSICION PARA ENCERRAR LA LLAMA DE COMBUSTION INCOMPLETA (9) PARA INSUFLAR UN FLUJO SECUNDARIO DE AIRE A LA SUPERFICIE DE BANDA DE ACERO INOXIDABLE (3) EN UNA DIRECCION VERTICAL A LA MISMA O CON UNA SUAVE INCLINACION HACIA LA DIRECCION MEDIA DEL EXTREMO FRONTAL DE LA LLAMA DE COMBUSTION INCOMPLETA (9) Y UNA BOQUILLA DE AIRE PARA LA GUIA DE LA LLAMA (6) INSTALADA ENTRE EL PAR DE BOQUILLAS SECUNDARIAS DE AIRE (5) Y UN CONDUCTO DE ESCAPE (7) PARA ASPIRAR Y DESCARGAR LA LLAMA DE REACCION INCOMPLETA (9'') DE LA LLAMA DE COMBUSTION INCOMPLETA (9). UN FLUJO DE AIRE A LO LARGO DE LA DIRECCION DE MOVIMIENTO (10) DE LA BANDA DE METAL INOXIDABLE (3) Y DE LAS BOQUILLAS SECUNDARIAS DE AIRE (5), MEDIANTE LAS QUE SE INYECTA AIRE PARA GUIAR LA LLAMA HACIA LA LLAMA DE REACCION DE LA COMBUSTION (9'') EN LA DIRECCION VERTICAL DE LA DIRECCION DEL MOVIMIENTO DE LA BANDA DE ACERO INOXIDABLE (3) O EN UN ANGULO INCLINADO, SE PRODUCE EN EL LADO SUPERIOR DE LA CORRIENTE DEL HORNO DE RECOCIDO CONTINUO (2) PARA DEPOSITAR EL HOLLIN SOBRE LA SUPERFICIE DE LA BANDA DE ACERO INOXIDABLE (3) DE FORMA EFICIENTE, UNIFORME Y ESTABLE, DE FORMA QUE LA BANDA DE ACERO INOXIDABLE LAMINADA EN FRIO PUEDA SER RECOCIDA DE FORMA CONTINUA.
