摘要

•The updated high lights are as follows: A simplified homogeneous reduction scheme in the fuel-rich zone was identified.•A semi-empirical NOx model was proposed for large eddy simulation.•LES prediction on NOx is better than RANS, especially in strong turbulent flow.•The optimized OFA ratio is about 30%, where furnace outlet NOx is the minimum.
