In this paper,the numerical simulation on the flow field of a four-channel coal burner was investigated with Fluent software.The three-dimension model was created with UG software.The structure was meshed by using Gambit software.The realizable κ-ε turbulence model and simple method were adopted.The variation of the inner flow field of the burner was studied and analyzed.The results simulated to the burner by the realizable κ-ε turbulence model show that the contours of the flow field accord with the actual condition and the realizable κ-ε model is proved to be feasible and the results of simulation are creditable.That will have important significance to the improvement of the structure and parameter optimization of the four-channel coal burner in the future.
