Abstract
This study investigates the process of enhancing the efficiency of the afterburning chamber in the Vanyukov furnace. Various operational modes of the furnace and the chamber were analyzed to identify optimal conditions for sulfur oxidation and afterburning, as well as methods for reducing accretions. Measurements and analyses of off-gas compositions were conducted, and the dust content was determined.
Simplifications and assumptions were applied in the calculations, enabling the modeling of gas flow, thermodynamic processes, velocity profiles, and interaction zones. Some thermodynamic calculations of counter-penetrating gas jets were based on hypotheses derived from heat exchange theories in mixing devices. Experimental results of numerical modeling and predictive simulations within the afterburning chamber are presented. Parameters were measured, and aerodynamic characteristics of the tuyeres were charted at an average oxygen supply to the chamber of no more than 2500 n.m3/h (38 n.m3 per ton of batch load). Recommendations for effective technological operations were proposed. The expertise of specialists from the Sredneuralsk Copper Smelter, along with the results of trials and process modeling, facilitated the selection of the optimal tuyere air distribution. The findings reveal the complexity of aerodynamic and thermodynamic processes occurring within the afterburning chamber. These include interactions between tuyere cooling airflows, heat release from exothermic oxidation reactions, and forced and natural convection of off-gases with varying temperature gradients, all visualized within a single projection.
