一、前言 以水煤浆代油有着明显优越性,但带来的诸如出力下降、炉底积灰、炉内结渣、对流受热面积灰磨蚀和环境污染等问题尚需解决,大量水份的存在要求加强对水煤浆喷雾着火燃烧特性的研究,文献[1]提供了悬挂单滴水煤浆的试验结果,但对水煤浆喷雾至今仍缺乏相应的了解,尽管水煤浆喷雾燃烧已在实验室炉和工业炉上获得了成功. I. Introduction Coal-water slurry substitution has obvious superiority, but problems such as output decline, bottom fouling, furnace slagging, convection and heating area gray abrasion and environmental pollution have yet to be solved. A large amount of water However, there is still a lack of understanding of CWS spray. Although coal-water slurry spray combustion has been studied for a long time, Laboratory furnaces and industrial furnaces have been successful.
