【摘要】 本文介绍了MFP、MPY、MLP型管式双股同轴射流煤粉烧嘴和这些新烧嘴的实验结果及其应用。主要内容包括: 1)空气通过可动塞块旋流器产生旋流; 2)在烧嘴中安装钝体; 3)对MPY和MLP型烧嘴安装渐扩延伸段; 4)热的燃烧产物在旋涡中回流提供了燃料点火时所需的热量。更多还原

【Abstract】 Three types of circular double concentric jet pullverized coal burners(MFP, MPY and MLP) and their experimental results and applications are described in this article. The major items are;1) Air swirl generated by movable-block swirl generator;2) Bluff bodies set in to combustion nozzles;3) Fitting of divergent extension to MPY type and MLP type burners;4) The heat required for ignition can be met by the hot combustion products recirculated in the vortex.更多还原
