缝宽对开缝钝体燃烧器着火及燃烧影响的研究

Investigation on Influence of Slit Width on Pulverized Coal Ignition and Combustion with Slitted Blunt Body

本文通过对具有不同缝宽的开缝钝体燃烧器热态实验研究结果的分析，得出了开缝钝体燃烧器缝宽过大或者过小均会影响到煤粉的着火及火焰稳定的重要结论，而且得到了在本实验条件下缝宽的最佳值即缝宽大约为钝体边宽１０％左右。这一结论为开缝纯体燃烧器的工业应用提供基础。

On the basis of analysis of hot experimental results with different slit width of slitted blunt body, a very important conclusion is obtained, that is, the slit width has much influence on the pulverized coal ignition and flame stability and the optimal value of slit width is about 10% of blunt body width under condition of experiments. This is very useful for slitted blunt body used in power plant.
