Abstract

We have developed the novel oxygen-enriched burner using self-induced oscillating phenomenon of jet flow which have excellent radiation heat transfer characteristics. We revealed the flame property suitable for radiation heat transfer is obtained by extending the oscillation cycle. Optimizing connecting tube length and diameter, we got stable oscillating flame on 1 second-oscillation period. At this time, the relationship between the burner structure including the connecting tube and the oscillation period can be easily evaluated by the dimensionless tube length and Strouhal number. In addition, combining multi-staged combustion technology, the burner can improve heat transfer efficiency by 9.1 % compared with conventional oxygen-enriched burner. We confirmed that the burner has low NOx emission level below 55 ppm.
