摘　　要：采用标准k -ε双方程模型和SIMPLE算法对卧式煤无烟燃烧锅炉的炉膛冷态空气动力场进行了数值模拟 ,预报了炉膛冷态空气动力场的速度分布、压力分布。并对预测结果进行了定性的分析。The aerodynamics field of horizontal coal fired sootless boiler is simulated in the paper using standard k ε two equation turbulent model and SIMPLE algorithm. The distribution of gas velocity, the static pressure in the furnace is predicted. The simulation result is analyzed qualitatively. The result shows that the better aerodynamics field can be obtained when the eccentric impinging & multi orifice secondary air has been applied to.
