Abstract

METODO Y APARATO PARA LA POST-COMBUSTION (AFTER-BURNING) DE LOS GASES COMBUSTIBLES PRESENTES EN UN REACTOR METALURGICO UTILIZADO PARA FUNDIR METALES. EL FLUJO EN TORBELLINO DE UN GAS OXIDANTE QUE EMANA DE UN INYECTOR RADIANTE (10) CON UN DIFUSOR EN FORMA DE EMBUDO (CONICO) (14) ORIGINA UNA REACCION ENTRE LOS GASES COMBUSTIBLES Y EL GAS OXIDANTE EN LA SUPERFICIE INTERNA (13) DEL DIFUSOR (14) CALENTANDO DE ESE MODO AUN MAS LA SUPERFICIE INTERNA (13). EL CALOR PROVENIENTE DE LA SUPERFICIE INTERNA (13) DEL DIFUSOR (14) ES RADIADO DENTRO DEL REACTOR EN DIRECCION AL METAL (12). SE PUEDE SUMINISTRAR GAS COMBUSTIBLE AL INYECTOR RADIANTE PARA AYUDAR EN EL CALENTAMIENTO DE LA SUPERFICIE INTERNA (13) DEL DIFUSOR (14).
