摘　　要：采用数值模拟的方法,以Fluent为工具,对某电厂1 000 MW机组微油点火系统进行研究。以Gambit对微油点火燃烧器进行网格划分,湍流模型采用RNG K-ε双方程模型,辐射传热采用P-1辐射模型,煤粉颗粒跟踪采用离散相模型,最终获得微油燃烧器内流场、温度场、组分场以及煤粉颗粒的运动轨迹。模拟结果可作为其微油点火系统运行和维护的借鉴和参考。Based on Fluent,tiny-oil ignition burners of 1 000 MW units were researched by numerical simulation.Gambit was used to build gridmesh of the burners.Gas flow was described with RNG turbulence models;radiative transfer was described with P-1 radiation models;the motion of pulverized coal was described with discrete phase models.Finally velocity field,temperature field and motion trajectory of pulverized coal were attained.The result could be helpful for operation of tiny-oil ignition systems.
