摘要
针对浓淡燃烧器两相流的分离特性和阻力特性,采用冷态模化试验进行研究,全面了解它们的特性,以便改进燃烧器的性能。研究表明:浓淡分离装置的撞击挡块高度、挡块与隔板的距离都可以作为煤粉浓度调节的手段;挡块高度和气流速度对阻力损失的影响较大。
The separatikon characteristics and resistance characteristics of twophase flow in rich lean burner were studied by cold model experiment realizing their characteristics roundly so that to improve burner capability. Study shows that the impact block's high and the distance between block and clapboard are available means for pulverized coal rich lean regulation, block's high and gas flow velocity influence resistance loss greatly. Figs 8 and refs 4.
