Abstract

This study aims to establish design parameters for an oxy-fuel burner to efficiently combust LDG, a low-calorific fuel from steelmaking processes. Using a 100,000 kcal/h experimental burner, combustion characteristics were analyzed with design parameters including Re, J and S/D number. The results indicated that the momentum flux of the oxygen jet significantly impacts combustion. Variations in the S/D number affected the flow of fuel and external air. CO emissions increased when the S_F/D_A number exceeded 1.5 due to insufficient fuel entrainment. To reduce NO emissions, minimizing external air entrainment by adjusting the number of oxygen nozzles and maximizing the S/D number was effective. This research provides essential design parameters for stable and efficient combustion of low-calorific fuels such as LDG.
