| 摘 要： | 本文实验研究了驻涡煤粉燃烧器的气流结构及燃烧机理。在ＢＤ（ＢａｒｃｈａｎＤｕｎｅ）型旋涡发生器的特殊作用下，燃烧器出口处形成了一个利于煤粉着火和燃烧的高温热核和高浓度煤粉区域，从而使煤粉着火迅速，燃烧稳定。实际应用证明，驻涡煤粉燃烧器在节省锅炉点火及助燃用油，提高锅炉的低负荷稳燃能力等方面，具有显著作用。

| Abstract: | This paper deals with the experimental study of the air flow flow field and combustion mechanism of a Barchan Dune (BD)vortex pulverized coal burner. Under the special action of the BD vortex generator there emerged at burner outlet a high-temperature nucleus and high-concentration pulverixed coal region, which promotes the ignition and combustion of the pulverized coal, resulting in a speedy ignition of the pulverized coal and significant enhancement of its combustion stability. Practical applivations have shown that the AD pulverized coal burnerw play a key role in reducing start-up oil consumption during boiler ignition and enhancing the boiler low-load combustion stability, etc. |
