Design and Evaluation Measurements of a Swirl Stabilized Laboratory Burner

AbstractThis article presents gas velocity and temperature measurements obtained in a versatile multi-fuel swirl-stabilized laboratory burner of 100 kW total thermal input, which was designed as a scale model of a 110 MW coal burner operating in a cement rotary kiln. The laboratory burner is able to produce flames with different aerodynamic characteristics, namely, the independent adjustment of swirl to axial air and to burn a combination of gaseous, liquid, and pulverized solid fuels; only gaseous fuel, i.e. methane, was used in the present investigation. Experimental measurements were obtained in the near-burner region, with and without combustion, under varying operating conditions. The present investigation was mainly focused on the effect of swirl and its interaction with the combustion process.
