摘要
准东煤在中国能源利用中具有重要地位,由于特性独特,对准东煤燃烧颗粒物的生成特性和相应控制方法的研究十分必要。本文在沉降炉中研究了1000~1300℃下准东煤高岭土添加对PM_1（空气动力学直径小于1μm的颗粒物）生成的影响。实验结果表明,随着温度的升高,准东煤PM_1的生成量先急剧减少后略微增加,并向小粒径偏移。高岭土的添加对PM_1的作用在不同温度下差异明显,1000℃时高岭土添加大幅降低了PM_1的生成量;1100℃时,PM_1的生成量较原煤有一定的降低;1300℃时反而略微增加了PM_1的生成。
Zhundong coal will play a great role on the energy structure of China in the future.As its coal property is very special,it is essential to study the particulate matter formation characteristics of Zhundong coal and related control methods.Experiments were conducted on a drop tube furnace at temperature 1000~1300℃ to study the effect of kaolin addition on the particulate matter formation of a Zhundong coal.Results showed that,as the temperature increased,the amount of PM_1 during Zhundong coal combustion were largely reduced at first,and slightly increased later,with the peak size became smaller.The addition of kaolin showed different performance at different temperatures,the PM_1 was greatly cut down by kaolin at 1000℃.When increased to 1100℃,the PM_1 was reduced to some extent.While at 1300℃,even more PM_1 was produced with kaolin addition.
