Abstract
PROCEDIMIENTO DE RECUPERACION DE GASES DE COMBUSTION EN HORNOS DE CALENTAMIENTO INDIRECTO PARA CREAR UNA ATMOSFERA ADECUADA EN TRATAMIENTOS TERMICOS DE METALES. CONSISTE EN APROVECHAR LOS PRODUCTOS DE COMBUSTION DEL CALENTADOR INDIRECTO, A BASE DE TUBOS RADIANTES, QUE CONTIENEN N2, CO2, H2O Y O2 PARA CREAR UNA ATMOSFERA DE TRATAMIENTO ADECUADA DENTRO DEL HORNO. PARA ELLO, LOS GASES DE LA COMBUSTION PASAN A TRAVES DE UN PURIFICADOR CATALITICO PARA ELIMINAR LOS PRODUCTOS NO DESEADOS Y MEZCLARLOS DESPUES CON METANO PARA FORMAR LA ATMOSFERA DE TRATAMIENTO ADECUADA. PREVIAMENTE, LOS GASES DE LA COMBUSTION HAN CALENTADO EL HORNO A TRAVES DE LOS TUBOS RADIANTES Y HAN SIDO ENFRIADOS Y COMPRIMIDOS PARA DEJARLOS EN CONDICIONES DE UTILIZACION EN EL PROCESO DESCRITO.
