单角煤粉燃烧炉中煤粉着火与稳燃的数值模拟

Numerical Simulation for the Igmition and Flame Stability of Pulverized Coal in a Single Pulverized Coal Furnace

在自行建立的数学模型基础上，对单角煤粉燃烧炉中煤粉着火与火焰稳定性进行了详尽的数值模拟。给出了直流式燃烧器、钝体燃烧铭及开缝钝体燃烧器的数值模拟结果，得到了与实验一致的结论，还针对直流式燃烧器考察了影响煤粉着火与火焰稳定性的各个因素。

ased on a mathematical model developed by the authors, numerical simulation has beenmade for the ignition and flame stability of pulverized coal in a single pulverized coal furnace.Numerical simulation results of a straight-flow burner, bluff-body and slit bluff-body burn-ers are given. For a straight-flow burner with a rectangular section, a series of factors af-fecting the coal ignition and flame stability have been investigated.
