AI Technical Summary
In existing hot air sintering technology, the determination of the amount of hot air added lacks precise and dynamic scientific basis, which makes it impossible to achieve a precise balance between maximizing energy saving and stabilizing the production process, thus limiting the full realization of energy-saving potential.
A dual-criteria model for determining the amount of hot air added was constructed, combining combustion aerodynamics and thermodynamics to ensure the sufficiency of the combustion process and the high efficiency of hot air utilization. By calculating the excess air coefficient and hot air substitution efficiency, the lower and upper limits of the amount of hot air added were set to achieve scientific decision-making.
It achieves maximum energy-saving benefits while ensuring stable sintered ore quality, quickly responds to changes in raw materials and operating conditions, avoids the negative impact of incomplete combustion or excessive hot air on production, and improves control precision.
