摘 要: | 分析了朱家峁长焰煤硫分组成、可选性及脱硫的可行性,结果表明,利用现有的物理分选无法得到S_(t,d)小于1.0%的产品,选择高精度的重介质分选工艺,精煤硫分能降到1.4%;小于0.5 mm粒级煤泥采用小直径重介质旋流器分选后能得到S_(t,d)小于1.0%的产品,优于常规浮选工艺;综合分析表明,该矿产品适宜配煤造气。

Abstract: | Constituents of sulfur,feasibility of its removal and washableability of Zhujiamao long-flame coal analyzed.Result denoted that:with existing physical separation technique,no concentrate of sulfur content less than 1.0%be obtained;with high-efficient HM process, sulfur content be reduced down to 1.4%;for slime of less than 0.5 mm,with small-diameter HM cyclone,sulfur content be reduced down to less than 1.0%,being better than that by flotation.Comprehensive analysis gives that this coal is suitable to be a stock admixture for gasification. |

Keywords: | long - flame coal sulfur removal comprehensive utilization study |
