摘要
利用5种成浆性能好的单煤、4种成浆性能差的单煤和2种成浆性能中等的单煤进行配煤组合,通过实验考察了配煤的成浆性能.结果表明,通过配煤可以提高成浆性能差的单煤的成浆效果,其中成浆性能好的配煤组合是有淮南B煤和神火煤两种煤的配煤组合,成浆性能较差的是大会战煤和华亭煤组合,最大成浆浓度仅为61.58%.实验发现,淮南B煤与成浆性能较差的煤种进行配煤可以提高其成浆浓度,大会战煤种虽然自身成浆性能较好,但与成浆性能差的煤种进行配煤不能收到很好的成浆效果.
In this article, five coal with high slurring quality, four coal with low slurring quality and two coal with medium slurring quality is taken as sample for blending coal＇s slurring experiment. The blend coal is made of high slurring quality and low slurring quality coal in 1 ： 1 proportion. The slurring results show the low slurring quality coal＇s CWS＇ concentration is improved by blending with the high slurring quality coal. The higher slurring quality blend coal contains Huainan B coal and Shenhuo coal. The lowest slurring quality blend coal is blended by Huating coal and Dahuizhan coal, whose CWS＇ concentration is 61.58%. It is got from the experiment that the Huainan B coal is an excellent coal for coal blending to improve the slurring quality of the low slurring quality coal. Dahuizhan coal has high slurring quality, but it doesn＇t suitable for coal blending to improve the slurring quality of the low slurring quality coal.
