Pro/E was used to build the model of fluid area of the three leaves rotary kiln, and CFD(computational fluid dynamics) fluid simulation software Fluent was used, the boundary conditions were set, and the non-premixed combustion model and discrete phase model were chosen to simulate the temperature distribution, the kiln temperature distribution curve was drawn. Through the analysis of the influence parameters such as primary wind speed, air temperature, swirl vane angle,secondary wind speed, oil injection half angle, the results showed that the primary wind speed in the 50-60 m/s and the temperature in 200 ℃ is more appropriate; and suitable swirl vane angle is about 30°, the secondary wind speed in the 150 m/s is more appropriate. When the fuel injection angle is 15°, it has better effect. The results of the analysis provide the reliable basis for the 3 leaves rotary kiln design processing and engineering applications.
