双回流燃烧器实验研究与应用

Experimental Study of a Dual Return-flow Burner and Its Application

本文针对国内电站锅炉燃用劣质煤所存在的着火困难、燃烧不稳定和燃烧效率低等问题，提出了能产生内回流区和外回流区的双回流新型结构直流燃烧器，分析讨论了它的实验室冷态试验和热态试验结果，介绍了这种燃烧器在工业应用中的情况。

In view of the existing problems related to the firing of low-grade coals in home-made utility boilers, such as ignition difficulty, instable combustion and low combustion efficiency, etc the authors have proposed a new type of direct flow burner capable of producing both and inner an outer return flowzone. Its laboratory cold and hot-stats test results are analyzed and discussed followed by a brief description of the industrial use of such burners.
