选煤尾矿水煤浆在中小型热电机组中燃烧的可行性分析

Possibilities of coal water slurry combustion prepared from rejects in small and medium thermoelectric units

介绍了利用选煤厂微粒尾矿制备的水煤浆应用于中小型热电机组的可能性,确定了该燃料在ДКВР10-13锅炉中燃烧的稳定参数。结果表明:研制的热电机组可有效用于燃烧选煤尾矿(煤泥)水煤浆,锅炉的效率值达到80%或更高。试验结果可为建设电能1.2 MW燃选煤尾矿水煤浆的热电自动化机组提供参考。

Introduce the preparation of coal water slurry from rejects in coal preparation plant.Explore the possibilities of burning this coal water slurry in small and medium thermoelectric generators.The parameters of stable combustion in the ДКВР 10-13 are established.The CHP units can fully burn the CWS prepared from tailings（slime） of coal preparation plants.The thermal efficiency of the boilers can be up to 80 percent or higher.The test results show that the retrofitted boilers can burn CWS stably and effectively.The achievements can guide the construction of 1.2 MW CHP units burning coal slime-water slurry.
