Turbulent jet diffusion flames are quite common in industrial applications. Because of the large flow rates involved, usually the fuel gas is discharged through multiple burners and the mutual interaction between the jets determines flame shape, length, and general characteristics. Results are presented and discussed of an experimental investigation on acetylene turbulent dual jet diffusion flames. The study includes parameters of flames in parallel, divergent and convergent configurations. Tests with two parallel jets with addition of helium in the fuel stream were also performed and analyzed. The variation of overall flame length and of other flame physical characteristics, such as width, volume and conditions for lifting, are presented as functions of burner tip Reynolds number, jet distance from each other and inclination angle. The effects of diluent concentration in the fuel gas stream are presented for single and two parallel jets.
