Abstract A three dimensional turbulent combustion mathematical model, which contained K-ε two equation model for turbulent flow, mixture fraction f, for combustion reaction and concentration fluctuation g, for turbulent combustion, was developed and successfully applied to post-combustion process in BOF, even though the model did not address problems, such as, radiation, multi-phase flow and finite reaction rate, as the ones exist in real process. Nevertheless, some interesting results of off-gases flow pattern, temperature profile, and the shape of the turbulent flame of post-combustion in BOF were worked out. Two controllable parameters, lance height and the angle of sub-hole to horizontal were studied.
