Abstract:The combustion instability and deflagration of pure blast furnace gas sintering burner would reduce the combustion efficiency of blast furnace gas. In order to solve above problems, a new type of twin-swirl burner was proposed. The combustion flow law inside the burner was simulated, and the enhancement effect of the double-swirl burner on the combustion performance was analyzed. The results showed that the model can accurately predict the temperature distribution at the sintering surface, and the average error between the model and the field measured data was only 5.3%. The twin-swirl burner can effectively improve the combustion efficiency of blast furnace gas. Compared with the single swirl burner under the same working condition, the feed surface temperature was increased by 140 ℃ and the CO non-combustion rate was decreased by 15.9%. The results can provide an effective way for the performance improvement and energy-saving transformation of sintering equipment.
