摘要
Abstract
Gas-solid two phase flow in the pulverized coal duct pipe is simulated by the Fluent software, and the erosion wear in the pipe is researched by watching the solid particles' motion trail. Using the RNG k-ε turbulence model and Lagrange discrete phase model, the coupling numerical simulation of pulverized coal-air two phase flow field is conducted in the burner's coal pipeline. The flow field property and particles motion trail for the coal pipeline surface under different angles (a) are contrasted and analyzed. It is found that if α=≤15°, the erosion wear ratio inside the pipeline surface will be reduced. In addition to erosion wear, frictional wear also appears in the pipeline. The irrational factors in the burner design are found out through the analysis and discussion of calculation results. This paper provides certain guidance to the burner's structural improvement and relevant parameter optimization.关键词
