摘要
水煤浆是新型洁净燃料 ,有着很好的应用前景。在山东新汶矿业集团中心医院 2 .8MW热水锅炉改烧水煤浆的工业应用中 ,锅炉燃烧稳定 ,燃烧效率高 ,低负荷稳燃能力良好。本文对水煤浆在炉内燃烧过程 ,火焰中心 ,火炬长度 ,结渣特性等进行了分析。
Coal-water slurry is a new type of clean fuel, which enjoys very good usage prospects. Its use on a retrofitted 2.8MW hot-water boiler in the central hospital of Xinwen Mining Group Corp. is credited with a stable combustion even at low loads. The combustion process of coal-water slurry in the above-mentioned boiler is described along with an analysis of the flame center and length as well as slag-forming characteristics, etc. After its retrofitting the boiler has attained a thermal efficiency of 80.04% and a combustion efficiency of 99.36%. It is noted that the secondary-air swirl intensity, atomization air pressure, slurry pressure, air feed rate and boiler load, etc have a significant impact on the combustion of the coal-water slurry, and, hence, combustion efficiency. The retrofitting of this hot-water boiler can serve as a fine example for the retrofitting of other analogous boilers.
