In order to study the distribution and characteristics of particle deposition in the water-cooled flue of a sub-merged arc furnace,computational fluid dynamics(CFD)technology was used to simulate the behavior of flue gas deposition in water-cooled flue of the submerged arc furnace.The RNG k-ε turbulence model was used to calculate the flow field,and the discrete phase model(DPM)and JKR theory were used to establish the judgment criteria for parti-cle deposition.The particle deposition in the water-cooled flue of a submerged arc furnace was simulated and studied.The results showed that when the flue gas temperature increased from 873.15 K to 1 273.15 K,the deposition rates of the inlet section,section Ⅰ and tee section increased significantly compared to other pipe sections.The deposition rate of the inlet section increased from 0.12 g/s to 0.98 g/s,section Ⅰ increased from 0.11 g/s to 0.88 g/s,and tee section increased from 0.11 g/s to 0.45 g/s.
