Abstract

UNA TOBERA (10) PARA REFINAR METALES FUNDIDOS O FUNDIR FRAGMENTOS METALICOS U OXIDOS CARGADOS EN UNA VASIJA. LA TOBERA (10) COMPRENDE TRES TUBERIAS CONCENTRICAS (12,32,40) DE COBRE O ACERO INOXIDABLE ENCAJADAS EN REFRACTARIO (44). UNA CORRIENTE ANULAR DE GAS NATURAL RODEA UN CHORRO DE OXIGENO QUE A SU VEZ RODEA UN CHORRO CENTRAL DE GAS NATURAL. LOS TRES CHORROS SE EXPANDEN CUANDO FLUYEN A TRAVES DE LA TOBERA (10) Y A RESULTAS DE ELLO SE FORMA UN ACRECENTAMIENTO (50) EN LA PUNTA DE LA TOBERA. EL ACRECENTAMIENTO PROTEGE LA TOBERA (10) Y LOS CHORRO DE GAS ESTAN CONTROLADOS DE TAL FORMA QUE EL ACRECENTAMIENTO (50) SE MANTENGA EN EL TAMAÑO DESEADO QUE NI BLOQUEE LA TOBERA (10) NI PERMITA EL RETROQUEMADO DE LAS TUBERIAS (12,32,40).
