Damage reasons of the rotary kiln of pulverized coal burners conveying pipe is related with many reasons. This paper analyses the numerical simulation of the gassolid two-phase flow field in the coal channels of pulverized coal burners in burner with eroded wall material. For calculation was used k-ε turbulence model and Lagrangian discrete phase model. Results compares combustion conditions in the two-phase flow characteristics and particle trajectory model under different erosive wear distribution. Calculations was made for three different shapes of burner as a result of erosive wear. For that geometries was calculated combustion in rotary kiln, and estimated shape of flame in kiln chamber. Was find that the erosion rate is important for combustion in rotary kiln, and find that suggested method of calculation was proper for this subject. This will have some significance to the improvement of the structure and parameter optimization of kiln burner in the future.
