Técnicas capazes de usar o oxigênio do ar atmosférico em queimadores industriais

Abstract

The study developed an oxy-fuel system using atmospheric air/GLP as an alternative to pure oxygen for aluminum brazing in window-type air conditioners, aiming to reduce industrial costs. An experimental platform was built to measure temperature and brazing time, using thermocouples and real-time data acquisition. The results showed that the system meets the 45-second production cycle, with cost reduction and maintained process quality.
