  "abstract": "Symmetric burner arrangements with uniform heat release are the default design for cracking furnaces. However, the present study reveals that this symmetric layout leads to inferior heating conditions and reduced ethylene yields in specific coils. Therefore, an imbalanced heating strategy is proposed: side burners are grouped by location, with the fuel flow rate of Group L set to four times that of Group R while maintaining the same total fuel consumption. This approach increases the heat load on the disadvantaged coils by up to 2.65% and boosts their ethylene yields by nearly 10%, improving the overall average yield by 4.09%. Remarkably, even with Group R fully shut off, the averaged ethylene yield increases by 3.86%, demonstrating that highly imbalanced heating strategy outperforms the conventional symmetric arrangement. Given the limited yield improvements achieved under the conventional framework over decades, a new operational philosophy for high-efficiency cracking furnaces is warranted.",
